Full textAbstract:
Weigh-in-Motion (WIM) systems have improved the process of collecting data from heavy vehicles on the U.S. highway system and enforcing the laws that govern vehicle weights. The benefits of WIM are reaped by everyone from highway designers and voernments officials, to truck drivers and transportation industry owners. The data collected by WIM devices is essential for proper pavement design, developing pavement management systems, weight enforcement strategies, modeling traffic improvement projects, and predicting load-related distresses and performance. While WIM offers many advantages over its alternative, static weighing, the technology is limited by problems associated with the accuracy of its measurements. Weigh-in-Motion systems that lack accuracy require vehicles to travel slower and can result in higher queues, longer delays, and potential hazards. For these reasons, WIM system performance must be improved in order to adequately serve its purpose.
In order to evaluate WIM system performance and determine what vehicle characteristics have the most affect on it, two systems in the Commonwealth of Virginia were evaluated. The first system was an in-service WIM system at the Troutsville weigh station on I-81. The Troutsville station had bending plate WIM scales located in both the northbound and southbound directions. The second system in a newly developed WIM system manufactured by Omni Weight Corporation (OWC) and was installed at the Virginia Smart Road for evaluation. The OWC scale is a completely sealed and buried system that has ten strain gauge sensors in its interior.
Evaluation of both scales was performed by conducting a number of test runs under varying load conditions. Testing at Troutsville was performed using four different test vehicles with multiple loads on each. Variation in load was achieved by loading the test vehicles with various numbers of concrete Jersey Walls. Testing on the OWC scale was performed using only two test vehicles while varying the speed, load, tire pressure, and direction of travel over the scale.
The study showed that the scales at the Troutsville weigh station yielded 10% error or less on only 77% of the tests, not complying with the required 95% set forth by ASTM E-1318. In comparison, using the manufacturer's processed data for the OWC scale yielded only 18% of its tests with 10% error or less, far below the ASTM standard. A model was developed to re-calculate the axle weights using the raw sensor data from the OWC scale; and an evaluation of the accuracy of this data showed that the OWC scale performed much better. While compliance with the ASTM standards was still not achieved, it rose from 18% to 71% of the tests having 10% error or less. Repeatability of the Troutsville scales and OWC scales was found to be comparable.<br>Master of Science

Full textAbstract:
The thesis is concerned with road transportation of fuel. In theoretical part there are described the legal clauses that are related to this issue. The most detailed regulations can be found in the European Agreement on the International Carriage of Dangerous Goods by Road (so called Agreement ADR). Hence the biggest part of the theoretical section is devoted to these regulations. Instructions for transportation of diesel and petrol have been chosen from this international agreement and explained. Practical part deals with particular carrier of fuel - company Petrotrans s.r.o. Standard of service is compared according to several different customers, established demands on safety of fuel transportation are decribed and security of consumption tax in international fuel transportation is analysed.

Dissertação de Mestrado Integrado em Arquitetura, com a especialização em Arquitetura apresentada na Faculdade de Arquitetura da Universidade de Lisboa para obtenção do grau de Mestre.<br>Através de um olhar sobre Alepo, pretende-se com este exercício
aplicar o desenho projetual a uma visão de paz para 2060, assumindo o
período pós-guerra como otimista e próspero. Paralelamente à reconstrução
do tecido urbano afetado pelos conflitos da Guerra Civil Síria, existirão
novos projetos que influenciarão não só o futuro dos habitantes locais, mas
também dos visitantes curiosos que anseiam por conhecer este lugar.
Esta temática surgiu da vontade de contribuir com uma resposta
arquitetónica a um projeto infraestrutural ambicioso, cujo impacto se tornará
global. Através de uma reconciliação entre o imaginário islâmico local
e o desenvolvimento tecnológico do território Euroasiático, a cidade será
reintegrada numa rota ancestral de idiomas, culturas e bens.
A estação ferroviária foi a resposta encontrada para as premissas
definidas, permitindo a inclusão da Síria na Nova Rota da Seda que unirá,
através da circulação de comboios de alta velocidade, a China às portas da
Europa.
Considerando o papel que este elemento terá na regeneração de
Alepo, existe oportunidade de estudar antecipadamente o seu impacte, desde
a escala do território até à do passageiro que dele poderá usufruir, viajando
a bordo de um meio de transporte sustentável para qualquer parte do

architectural design to a vision of peace for 2060, assuming the post-war
period as optimistic and prosperous. Alongside the reconstruction of the
urban fabric affected by the Syrian Civil War conflicts, there will be new
projects that will influence not only the future of locals, but also curious
visitors who want to know the site.
This theme arose from the desire to contribute to an architectural
response to an ambitious infrastructure project, which impact will become
global. Through a reconciliation between the local Islamic traditions and the
technological development of the Eurasian territory, the city will be reintegrated
into an ancient road of languages, cultures and goods.
The railway station was the answer found for the stated assumptions,
allowing Syria to be included in the New Silk Road that will connect
China to the gates of Europe through the movement of high-speed trains.
Considering the role this element will play in the regeneration of
Aleppo, there is an opportunity to study in advance its impact, from the
scale of the territory to the scale of the passenger who will use it, traveling
aboard a sustainable mode of transport to any part of the world.<br>N/A

Full textAbstract:
Att hålla de svenska vägarna säkra under vinterhalvåret är något som kräver stora resurser och kostar samhället stora pengar. De system som idag finns för att ge information om hur väg förhållandena ser ut är inte tillräckliga. Det finns för få väderstationer utplacerade runt om i vägnätet för att kunna ge en bra geografisk upplösning åt de som beslutar om ut dirigering av insatser. Att ta fram en kostnadseffektiv och helt trådlös väderstation som kan placeras ut oavsett tillgång till strömförsörjning eller trådbunden kommunikation är något som funnits som önskan hos de stora aktörerna inom vinterväghållningen i Sverige en längre tid. Vid ökad geografisk upplösning av väderförhållandena i vägnätet kommer det möjliggöras mer riktade insatser av vinterväghållningen. Detta skulle resultera i minskat slitage på verktyg samt minskat användande av salt på vägbanan vilket innebär ekonomiska vinster och inte minst miljömässiga vinster. Intervjuer och enkätsvar har legat till grund för framtagning av ett underlag för en väderstation av detta slag. Under arbetet med väderstationens underlag har ytterligare önskemål och idéer från människor som är aktiva inom branschen dykt upp. Detta har lett till att examensarbetet inriktat sig framför allt på att ta fram ett nytt sensorsystem som helt kontaktfritt från vägbanans yta detekterar vad som finns på vägytan när det gäller torr, våt eller isig vägbanan. Ett komplett sensorsystem har utvecklats som placeras i vägbanan och mäter temperaturen samt helt kontaktfritt från vägytan detektera om vägbanan är torr, våt eller om det finns is på den. Sensorsystemet är helt batteriförsörjt och skickar data helt trådlöst från vägbanan. Detta gör det möjligt att använda flera sensorer i vägbanan och på detta sätt skapa ett sensornätverk som kan avgöra hur förhållandena ser ut på längre sträckor än i dagsläget endast i en punkt.<br>Keeping the Swedish roads safe during winter months is something that requires large resources and costs society a lot of money. The systems that provide information on road condition today are not enough. There are too few weather stations located around the road network to provide a good spatial resolution to those who decide if there is a need for ice- or snow removal on the roads. To provide a cost effective and completely wireless weather station that can be deployed regardless of access to power or wired communications is something that existed as a desire by the major contractors for the winter road maintenance in Sweden for a long time. A higher spatial resolution of weather conditions in the road network will make it possible to use more focused efforts where the road conditions are not good. This would result in reduced wear on the tools, less fuel consumption and reduced use of salt on the roadway resulting in economic gains and not least environmental benefits. Interviews and questionnaires were the basis for creating a base for a weather station of this kind. While working on weather station data, additional requests and ideas from people who are active in the industry emerged. This has led to the thesis work focused primarily on developing a new sensor system that completely contact-free from the road surface detect what is on the road surface when it comes to distinguish dry, wet or icy road surface. A complete sensor system has been developed that is placed in the roadway and which measures the temperature and uses a sensor that doesn't have any contact with the road surface to detect if the road surface is dry, wet, or if there is ice on it. The sensor system is battery powered and transmits data wirelessly from the road. This makes it possible to use multiple sensors in the roadway, thereby creating a sensor network that can determine what the conditions are at longer distances than in only one point.

Full textAbstract:
Since ancient times, roads have tied people and cultures together. Roads have been createdwith the aim of facilitating trade and cultural exchange among different regions in the world. After the technologic development in vehicle industry and dramatically increase of motoring in the world during the past century road communication has gained a great importance for transporting people and goods. Thus, good safety and accessibility on roads all year round is now a vital necessity for a healthy economy in all modern societies. In order to keep roads safe, available for use with high transport quality they need to be maintained in real time. One of the most difficult tasks in this context is to keep the roads in good condition and accessible even during winter. The main objective of this doctoral thesis is to attempt to specify the most efficient ways of executing winter road maintenance. The preliminary issue in this context is whether it is the use of current assistive tools, that is, technical aspects that should be optimized and developed or whether it is the way in which winter maintenance services are procured and outsourced, that is, contractual aspects that should be improved which could give the optimal impact for both clients and contractors and make winter road maintenance more effective, or both issues. In order to define the outline of the research project a comprehensive state of the art survey was initiated with the intention of collecting and gaining insights into the earlier studies in the research area. Three basic areas associated with the performance of winter road maintenance were considered to be most relevant for review due to the anchorage between the areas. The selected areas were climatological, technical and contractual aspects. The literature review was followed by an electronic questionnaire survey. The results of the study in this stage showed that current technical methods almost functioned in a reasonable manner but there was an imprecise dissatisfaction with the current maintenance contract. The second stage of the research consisted of a number of additional empirical investigations in order to identify contractual problematic issues behind the current winter road maintenance in Sweden. Generally, those factors that are rarely considered as potential underlying causes to costly performance of winter road maintenance in Sweden were studied in this research project for example improper use of related technical assistive tools, procurement of improper bundled winter services and inappropriate contract structure. This thesis consists of six papers, five of which are related to each other, and the first one is completely independent but within research area. Findings in the thesis contributes to extend understanding about; how designing appropriate contracts can improve winter road maintenance, how proper use of assistive tools can reduce unnecessary winter road maintenance costs and minimize road traffic disruptions and delays, how a partnering structure in contracts can create confidence and trust between clients and contractors that in turn leads to minimizing or eliminating conflicts and disputes between parties involved, how choice of appropriate procurement methods through proper bundling of winter road services can contribute to shorten the procurement process and create incentives for contractors, and how selection of proper payment mechanisms can contribute to higher service quality of performed winter road measures. Additionally, an adequate knowledge and understanding of climate, proper knowledge of road weather and its impact on winter road traffic is essential for contribution of better planning of how to maintain the road network during winter. Since understanding about winter issues and its effect on winter road traffic is far from complete and winter road maintenance in the cold regions is a similar challenge, broad and complex, the results of this research may even contribute to improving winter maintenance problems in the countries with severe winters like Sweden.<br><p>QC 20140227</p>

El texto completo de este trabajo no está disponible en el Repositorio Académico UPC por restricciones de la casa editorial donde ha sido publicado.<br>At present, topographic surveys in road projects are very important, since it allows us to know the conditions and variable characteristics of the area to be executed. Commonly these surveys are carried out using a total station, high precision equipment, which in turn generates a lot of demand for time in the field and a greater number of personnel for a wide study area. For this reason, another alternative for obtaining terrain data is the use of the photogrammetric technique with UAV, since the objective is to increase productivity in the topographic survey. In this article, the productive development generated in the crews was analyzed using the total station survey methodology and the UAV photogrammetric technique using balance charts with the aim of obtaining the productive, contributory and non-contributory works, since the latter two they do not add value to the development of the project. This research was carried out in a rural area with a study area of 3 Ha and its classification by orography is of type 2 soil (undulated terrain), located in the Cuculí town center, Chongoyape district, Chiclayo province in the department of Lambayeque, Peru. In order to demonstrate that the UAV survey reduces non-contributory work by 47.2%, among the most outstanding activities obtained in this research are the leisure time that the staff presents in different situations of the project development, care of topographic equipment and another of the most outstanding was the use of cell phones in the field, which do not provide efficiency in the development of data collection and therefore would increase in time and cost of linear works, sanitation and projects in open places in the stage of design engineering.

Full textAbstract:
The flow of goods to Russia has grown faster than the bottleneck can handle and the infrastructure on Finnish eastern borders has been stretched to the limit. The authors choose this topic according to their educational background and the direct and indirect future opportunities that can rise up for everybody by a possible solution. Purpose The main purpose of this thesis was to identify the main reasons for the inefficient border crossing process at the border station in Vaalimaa. The authors will analyse the current situation at the border crossing station in Vaalimaa from two different perspectives: Finnish Customs and Logistics Companies. The authors will propose a possible solution by improving the border crossing process Methodology Qualitative research method is used in order to get the most dependable information for the reasons of the problems. The aim was to get information about the current situation at the border crossing point in Vaalimaa rather than quantitative information. The qualitative research method will allow authors to go deeper inside the topic by interviewing the logistics companies, who are using the route via Finland to Russia and, as well as, Finnish customs and border guards, who are working in Vaalimaa. After the data collection, the authors will propose their own solution for the crossing border problems and they will conclude the research by measuring its validity and reliability. Conclusion The authors will present the main reasons for the inefficient border crossing process, which are bureaucracy, legislation issues, criminality level and poor IT-systems. In order to solve the problem and manage all the possible changes, Russia and EU should have a closely cooperation in any level. The authors after analysing the current situation in Vaalimaa, created the “One-stop” model as an improvement of the whole border crossing process.

The purpose of this study is to determine the most suitable remediation technique via geotechnical assessment of the landslide that occurred during the construction of Bursa-inegö<br>l-Bozü<br>yü<br>k Road at KM: 72+000-72+200 in an ancient landslide area.
For this purpose, the geotechnical parameters of the mobilized soil along the slide surface was determined by back analyses of the landslide at four profiles by utilizing the Slope/W software. The landslide was then modeled using coupled analyses (with the Seep/W and Slope/W softwares) along the most representative profile of the study area by considering the landslide mechanism, the parameters
determined from the geotechnical investigations, the size of the landslide and the location of the slip circle. In addition, since the study area is located in a second degree earthquake hazard region, pseudo-static stability analyses using the Slope/W software were performed incorporating the earthquake potential. The most suitable slope remediation technique was determined to be a combination of surface and subsurface drainage, application of rock buttress at the toe of the slide and unloading of the landslide material.
A static and dynamic analyses of the landslide was also performed through utilizing finite element analyses. The static analyses were calibrated using the inclinometer readings in the field. After obtaining a good agreement with the inclinometer readings and finite element analyses results, the dynamic analyses were performed using acceleration time histories, which were determined considering the seismic
characteristics of the study area.

Full textAbstract:
Because winter maintenance is so costly, Utah Department of Transportation (UDOT) personnel asked researchers at Brigham Young University to determine whether asphalt or concrete pavements require more winter maintenance. Differing thermal properties suggest that, for the same environmental conditions, asphalt and concrete pavements will have different temperature profiles. Climatological data from 22 environmental sensor stations (ESSs) near asphalt roads and nine ESSs near concrete roads were used to 1) determine which pavement type has higher surface temperatures in winter and 2) compare the subsurface temperatures under asphalt and concrete pavements to determine the pavement type below which more freeze-thaw cycles of the underlying soil occur. Twelve continuous months of climatological data, primarily from the 2009 calendar year, were acquired from the road weather information system operated by UDOT, and erroneous data were removed from the data set. To predict pavement surface temperature, a multiple linear regression was performed with input parameters of pavement type, time period, and air temperature. Similarly, a multiple linear regression was performed to predict the number of subsurface freeze-thaw cycles, based on month, latitude, elevation, and pavement type. A finite-difference model was created to model surface temperatures of asphalt and concrete pavements based on air temperature and incoming radiation. The statistical analysis predicting pavement surface temperatures showed that, for near-freezing conditions, asphalt is better in the afternoon, and concrete is better for other times of the day, but that neither pavement type is better, on average. Asphalt and concrete are equally likely to collect snow or ice on their surfaces, and both pavements are expected to require equal amounts of winter maintenance, on average. Finite-difference analysis results confirmed that, for times of low incident radiation (night), concrete reaches higher temperatures than asphalt, and for times of high incident radiation (day), asphalt reaches higher temperatures than concrete. The regression equation predicting the number of subsurface freeze-thaw cycles provided estimates that did not correlate well with measured values. Consequently, an entirely different analysis must be conducted with different input variables. Data that were not available for this research but are likely necessary in estimating the number of freeze-thaw cycles under the pavement include pavement layer thicknesses, layer types, and layer moisture contents.

The transport sector accounts for a third of Sweden’s total greenhouse gas emissions where cars and heavy trucks dominate the use of fossil fuels. The Swedish government is now intensifying the work for an electrified transport sector where electric roads could be an important part. Electric roads enable heavy vehicles to charge their batteries while driving, which is expected to contribute to environmentally friendly and time-efficient freight transports. To implement electric roads, availability of electric power along the electric roads will be required. This study presents a plan for connecting an electric road to the electricity grid in the electricity network area of Vattenfall Eldistribution. From the results, the idea was to present general conclusions from the experiences of the study, that could contribute in further implementation of electric roads. The road that has been selected for the study was the E4 between Gävle and Stockholm. A model for calculating the power demand along the electric road has been modeled and connection possibilities to transformer stations has been investigated. The analysis was based on three scenarios where different degrees of strengthening of the existing electricity network were assumed. In addition, a forecast for 2030 and a cost estimation for each scenario has been carried out. The result of the study indicates that for road sections close to larger cities, there are a larger number of connection options in comparison to rural areas. Furthermore, the designed solution in the study required strengthening of the electricity grid and the investment cost was 362 million Swedish crowns.

In the development of the project of a road, it is expected that centimetric deviations in the determination of the points coordinates of the reference bases cause small effects in the final results. Trying to verify the contribution of these deviations, several surveys were accomplished with the Total Station and GPS along the axis of a road projected in the city of São Carlos. In the end of the work several aspects are analyzed about the execution of these surveys, concluding on the advantages and disadvantages of each method and of the integration GPS and Total Station.

The word revise means to reconsider or modify as with text. If we think of the suburban landscape as a text, the culture of each era left documentation of their values, policies and way of life in the form of transportation networks and other infrastructure, such as Main Streets, squares and public buildings. While evidence of most of the everyday life of individuals of every era gets erased by the following era, infrastructure investments of each era are adaptively reused and remain to tell the story. This thesis documents the adaptive reuse of these suburban frameworks and develops a proposition for the appropriate next layer to accommodate a new culture of inhabitants.
Focusing on second generation suburbs, using Gwinnett County as a case study, this analysis identifies three problems of the current suburban situation: the problem of abandoned strips, a demographic shift, and the need for place. As new strip highways develop, old strips decline leaving abandoned shopping centers and declining property values. New development continues to move north and out of the county, and middle class residents, for which existing auto-oriented suburbs were created, move as well. A new, poorer, and more ethnically diverse population inherits the auto-oriented landscape left behind. This phenomenon is particularly concentrated along the southern portion of the Buford Highway corridor. Those with more money move closer to new development, while those with less money have less choice and are found near declining strips with fewer services, poorer quality housing and lower quality of life. Finally, county officials have expressed a desire for defining "the epicenter of Gwinnett."
I believe that there is no one "center" of Gwinnett, but a series of places defined by memory, design or events. I propose to improve the situation of these three problems with a light rail line that connects existing places and creates new walkable, livable places to improve quality of life. This connective piece will serve as a social condenser in lieu of a center, provide links between polar populations, and reactivate declining strips while creating a sustainable infrastructural spine for future growth in the region.

A pavement construction designed to cope with the different type of traffic loads; it is exposed to and at the same time it can resist the effect of the climate. A road structure consists of sub- and superstructure which is divided by a boundary known as terrace. During the construction of unbound layers (base course and sub-base course) in the superstructure, it is always ensured that the material meet the requirements for bearing capacity and the degree of compaction. These parameters are controlled by various laboratory tests and control methods. To obtain increased knowledge of the material and improve the quality of the compaction in the field, it is necessary to perform laboratory tests in order to determine material properties. A base course material 0/ 32 mm limestone from Gotland (Hejdeby) was investigated in this study. To determine properties of the material various laboratory tests such as proctor compaction test, Micro-Deval, Los Angeles, and grain distribution curve are conducted. To investigate how grain size distribution affects technical properties of the material, the 0/32 mm material was modified with two different samples; grain size distribution of 2/32 mm excluding superior material content, and 0+/32 mm with enhanced superior material content. The purpose of this study was to examine changes in material behavior during proctor compaction. Two aspects of changes in material behavior were emphasized in this study; the optimal water content and maximum dry density, as well as changes of both. As a reference for the limestone features, a traditional 0/32 mm tonalite material (granite) from Vällstaverket was used relating to proctor investigation. Material's resistance to abrasion and fragmentation was investigated by two methods: Micro-Deval and Los Angeles. The results were compared with other rock materials. Furthermore the bearing capacity of the material was verified by examination of the Young's modulus and degree of compaction, as well as properties of water content and dry density, at three trial areas on Gotland. This is performed with various methods such as static plate loading test, light weight deflectometer, density gauge/SDG200, and water/sand volume meter measurement test. By comparing results from different methods of measurement, it may indicate a relationship between these. Test area 3 consists of two smaller test areas which have different water content. The bearing capacity (Young's modulus) and the degree of compaction were measured after each roller passage. Different relationships were obtained between the amount of roller overpass, with Young's modulus of material; as well as degree of compaction. It was found in this study that limestone from Gotland (Hejdeby) maintain its position as construction material for the unbound layers of the road. The result from static plate load which indicated high E V2 values (Young's modulus) was obtained from the field, and it suggests that a fine bearing capacity can be achieved in the use of limestone.

Thesis, KTH, Skolan för industriell teknik och management (ITM), 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:kth:diva-258922.
Full textAbstract:
Due to legislative pressure on a global, European and Swedish level the heavy-duty transportation sector needs to drastically reduce its emissions. One potential pathway forward for the heavy-duty transportation sector is that of electrification, which would require novel infrastructure to be established in the form of stationary charging or dynamic charging through what is often called electric road systems (ERS). The aim of this thesis has been to investigate how developments in battery technology impacts the potential electrification of heavy-duty transportation in Sweden. The starting point is from the perspective of battery technology and the resulting impact that battery technology has on the provision of charging infrastructure. In order to analyse the relation between these parameters the market developments of lithium-ion batteries were explored and an empirical study of the likely stakeholders of an electrified heavy-duty transportation system was conducted. The study finds that battery technology has a substantial momentum and several stakeholders view the electrification of heavy-duty transportation as the most cost-efficient solution in the long-term. There is however a consensus that battery development has not yet progressed to a stage where the electrification of heavy-duty transportation is financially or technically viable. Developments in battery technology affect the prospects for stationary charging provision and ERS (i.e. dynamic charging) differently, with stationary charging being more dependent on positive developments. The relation between developments in battery technology and ERS is more complex as its deployment is not only dependent on market developments but is also highly dependent on decisive actions by policy makers. Developments in battery technology could however affect both alternatives positively in the long-term, as a sustained positive battery development will make fully electric heavy-duty trucks an attractive option for the market to pursue. Once a common belief in the electrification of heavy-duty transportation has been established the main issue described by stakeholders, ensuring a long-term positive business case, could therefore be achieved by both alternatives. The study concludes that for an electrification of heavy-duty transportation to be financially sustainable in the long-term, continued positive battery developments are a prerequisite.<br>Till följd av lagstiftningskrav på en global, europeisk och svensk nivå så måste tunga vägtransporter drastiskt minska sina utsläpp. En möjlig utveckling för tunga vägtransporter kan vara elektrifiering vilket skulle kräva en etablering av ny infrastruktur, antingen i form av stationära laddstationer, eller i form av elvägar. Syftet med denna uppsats har varit att utreda hur batteriutvecklingen påverkar förutsättningarna för att tunga vägtransporter i Sverige skulle kunna elektrifieras. Utgångspunkten har varit utifrån perspektivet av batteriteknologi och den påverkan som batteriteknologin har på tillhandahållandet av laddinfrastruktur. För att analysera relationen mellan dessa parametrar så har marknadsutvecklingen för litium-jon batterier utretts och en empirisk studie med de aktörer som troligen skulle vara delaktiga i ett elektrifierat transportsystem har utförts. Studiens slutsatser är att batteriteknologin har ett betydande momentum och att flera aktörer på sikt ser elektrifieringen av tunga vägtransporter som den mest kostnadseffektiva lösningen. Det råder dock en konsensus om att batteriutvecklingen ännu inte har kommit långt nog för att elektrifieringen av tunga vägtransporter ska vara tekniskt eller ekonomiskt gångbar. Batteriutvecklingen påverkar utsikterna för tillhandahållandet av stationära laddstationer och elvägar på olika sätt, där stationära laddstationer är mer beroende av en positiv batteriutveckling. Relationen mellan batteriutvecklingen och elvägar är mer komplex då etableringen av elvägar inte bara är beroende av marknadsförhållanden utan även är avhängig på ett starkt politiskt stöd. Batteriutvecklingen kan dock ha en positiv påverkan på båda dessa alternativ på lång sikt, då en ihållande positiv batteriutveckling skulle göra helelektriska tunga lastbilar till ett attraktivt alternativ för marknaden att eftersträva. När en gemensam övertygelse om att elektrifieringen av tunga vägtransporter är den optimala vägen framåt har uppnåtts så kan det huvudsakliga problemet som aktörer beskriver, upprättandet av långsiktigt hållbara affärsmodeller, uppnås av båda alternativen. Studien drar slutsatsen att för att en elektrifiering av tunga vägtransporter ska vara ekonomiskt hållbar på sikt så är en fortsatt positiv batteriutveckling en förutsättning.

Full textAbstract:
This Master of Arts project in Creative Writing was submitted to the School of Creative Media at Royal Melbourne University of Technology. It contains a full length feature screenplay for an un-produced road movie entitled Free Radicals. It is primarily a dark love story between the drug-addicted rent boy Roman and the budding actor, the protagonist Jonathan. It is however written in a conventional structure familiar to Hollywood professionals, and a good deal of humour is used to attract interest in the story. The storyline itself is more familiar to the audience of road movies and independent features in the US or European Art House ventures. The exegesis explores the history and the conventions of the road movie genre, in addition to the established and not often debated conventions of screenwriting theory. The thesis attempts to show how these theories were applied to the screenplay and how they influenced the process of writing it within an academic and commercial context. The MA project shows how different expectations may create a conflict in the personal writing process and inspire a product that makes compromises. The reason for reading this project may not only be the product itself but also the insight it offers into a screenwriting profession where it is often important to meet expectations.

Traffic collisions cost Uganda millions of dollars each year. The purpose of this descriptive case study was to describe the strategies and processes needed to implement a road management system. Such a system would significantly reduce the fatalities and accidents in Uganda, improve the transportation within Kampala's business district, and increase business profitability. Three conceptual theories framed the research study: management theory, strategic management theory, and criminology theory. Using a snowball sampling strategy, data were collected from open-ended interviews, questionnaires, observations, and archived documents from 20 administrative participants in the government and organizational leaders involved in the transport operations and transport services in the Kampala business district in Uganda. Data were analyzed using 3 phases: (a) interpretational analysis, coding, and grouping segments; (b) structural analysis, consistency, and quality; and (c) reflective analysis, consequences, what, when, where, and how. Five themes or action requirements emerged from the data analysis: to improve transport operations and transport services profitability, reduce traffic jams and fatalities, provide sufficient driving training, maintain road infrastructure, and maintain traffic law enforcement. The findings and recommendations from this study may improve the profitability of businesses, reduce the traffic jams and fatalities, and improve the gross domestic product of Uganda, thereby contributing to positive social change.

Urbanmorphology is the evolutionary process where urban centers experience growth or decline due to series of changes and events or changes leading to events. This thesis came about due to an event that has a big impact on an urban environment, a military base on a large swath of land was closed and the property became available for development. Closed military bases provide us with opportunities to accelerate urbanmorphology, to simulate the organic evolution of an urban center and to explore urban and architectural ideas that, otherwise, are very difficult to test. The results could be used as models for adaptation in other, less expansive and more restrictive applications. This opportunity allows us to address todayâ s constituencies using todayâ s technology, attempt to define our era and hopefully help in defining the future exactly as the past helped in defining ours.<br>Master of Architecture

SOUTH ROAD, a novel told in third-person limited, follows Adrienne Harris as she navigates the trials of her coming-of-age summer and then must deal with the aftermath. 1997: seventeen-year-old Adrienne Harris wants nothing more than to flee her eccentric grandmother’s rule and leave Harbor Point and never look back. When she meets her new neighbors, Adrienne knows her life will never be the same. Adrienne quickly falls in love with the charismatic Quinn Merritt. They decide to keep their relationship a secret since both families disapprove. This secret starts a chain reaction that seemingly leads to the suicide of the troubled and poetic Lucas Merritt. The summer culminates with Adrienne running away, pregnant and heartbroken. 2011: thirty-one-year-old Adrienne is an out of work line cook and single mother. The story opens as Adrienne reluctantly returns home to Harbor Point to care for her ailing grandmother. Once home, Adrienne has to confront the things that haunt her—the summer she met and lost both Merritt brothers, and also her dysfunctional relationship with her grandmother—in order to heal and repair her own life and her relationship with her daughter.
In the end, Adrienne discovers many truths that alter her perception of her past in Harbor Point. Adrienne is finally able to move forward and start to build a life for her and her daughter. Harbor Point, the last place in the world Adrienne Harris wanted to be, turns out to be the only place she wants to call home.

Full textAbstract:
This dissertation comprises two parts: Part I, which discusses the growing trend in project books in contemporary poetry, and Part II, a collection of poems titled, Road Debris. There is an increasing trend in the number of project books, which are collections of poetry unified in both thematic and formal ways. the individual poems in a project book share overt connections which allow the book to work on many different levels, blending elements of fiction and non-fiction or sharing a specific theme or speaker. While these books have the advantage of being easily memorable, which might gain poets an edge in book contests, there are also many risks involved. the main issue surrounding project books is if the individual poems can justify the book, or do they seem too repetitive or forced. As more poets, especially newer ones, try to use the project book as a shortcut to publication, it can result in poorly written poems forced to fit into a particular concept. By examining three successful cotemporary project books—The Quick of It, by Eamon Grennan; Incident Light, by H. L. Hix; and Romey’s Order by Astory Riley—this essay discusses how these books work in order to understand the potential of the project book. All of these books work in distinctly different ways, yet they all fall into the category of project book. While project books will inevitably result in poor imitations, it allows books of poetry to expand and explore in different directions.

Full textAbstract:
“Station to Station: Contemporary British Literature and Urban Space After Thatcher,” examines specific literary representations of public and private urban spaces in late 20th and early 21st-century Great Britain in the context of the shifting tensions that arose from the Thatcherite shift away from state-supported industry toward private ownership, from the welfare state to an American-style free market economy. This project examines literary representations of public and private urban spaces through the following research question: how did the textual mapping of geographical and cultural spaces under Margaret Thatcher uncover the transforming connections of specific British subjects to public/private urban space, national identity, and emergent forms of historical identities and citizenship? And how were the effects of such radical changes represented in post-Thatcher British literary texts that looked back to the British city under Thatcherism?
Through an analysis of Thatcher’s progression towards policies of privatization and social reform, this dissertation addresses the Thatcherite “cityspace” (Soja) and what Stuart Hall calls the “deregulation of the city” (23) as these open my research to issues of spatially affected identities in literary representations of the British city at the turn of the century. My four case studies move from a broad discussion of the effects of the heritage industry on the city and the individual (Iain Sinclair’s Lights Out for the Territory [1997]); to the relationship between space, identity, and the rolling back of the welfare state as it plays out in the stigmatization and neglect of council estate housing (Irvine Welsh’s Trainspotting [1993]); to representations of race and entrepreneurialism in the Thatcherite city (Monica Ali’s Brick Lane [2003]); and, finally, to representations of space, gay identities, and class during a period of institutionalized homophobia (Alan Hollinghurst’s The Line of Beauty [2004]). The project takes as its aim the tracing of various tentacles of Thatcherism as they creep across the spaces of the British city in a way that draws attention to how the processes and flows of Thatcherite neoliberal policies circulate across the spaces of the city, forever altering the ways in which individuals move and form identities within those spaces.

Full textAbstract:
Road lighting is widely recognised as an efficient traffic safety measure. However, we know too little about the effect of road lighting on accidents in a given situation and we do not know what kind of lighting that is optimal for the situation. Society today has a demand for energy savings, locally and globally, and we should not use more energy for road lighting than is necessary. In the field of road lighting the demand for energy savings is accompanied by a fast development of techniques and equipment that give great opportunities for energy savings. The opportunity already exists to adapt the lighting to the actual road, traffic and weather situation. It is a problem, however, that we do not know what lighting quantity and quality which gives the best benefit – cost ratio. The objective of this thesis is to contribute to more knowledge about the relationship between road lighting and traffic safety and thus make a basis for benefit – cost calculations (including environmental costs). The thesis is based on four studies about the safety effect of road lighting, reported in four papers. The first is a literature study, the second is a Norwegian before-and-after study, the third is a cross-section study of Dutch accidents and the fourth is a study of Dutch motorway accidents. The thesis also contains three appendices presenting some more details from the studies than were shown in the papers. The content of the four papers are presented and discussed as a whole in a (fairly comprehensive) introductory part consisting of 10 chapters, where conclusions about the safety effect are discussed and summarised. The thesis in addition discusses the benefit – cost ratio of road lighting, but it is not treated in any of the papers. It has been useful to discuss this matter in advance of the discussion of the future role of road lighting. In the literature study (Paper I), the mean effect of road lighting on injury accidents during darkness was found to be -30 %. The mean effect on fatal accidents was -60 %. The mean effect on pedestrian injury accidents was -45 %, and on motorways the mean effect on injury accidents was -50 %. In the Norwegian before-and-after study (Paper II), the estimated effect of road lighting on injury accidents during darkness was -28 %. The estimated effect was larger at high speed limits than at low speed limits. The estimated effect was smaller on roads with AADT (average daily traffic volume) > 8000 vehicles than on roads with AADT < 8000 vehicles. In the cross-section study of accidents on all Dutch roads (Paper III), the mean effect of road lighting on injury accidents during darkness was found to be -50 %, while it was -54 % when only rural roads were considered. The effect on pedestrian, bicycle and moped accidents was larger than the effect on automobile and motorcycle accidents, and the differences were statistically significant. There was no significant difference between the safety effects for different accident types (Rear end collisions, Frontal collisions etc.) and no significant difference between the driver age groups 60 – 74 years and 30 – 39 years. The effect on fatal accidents was found to be slightly larger than the effect on injury accidents. The mean effect on twilight accidents was 2/3 of the effect during darkness. In the study of motorway accidents (Paper IV), the effect on injury accidents during darkness was found to be -49 % on Dutch motorways, while the effect seemed to be much smaller on British and Swedish motorways. On Dutch rural roads and Dutch motorways, the estimated effect of road lighting on accidents during darkness was smaller during adverse weather and road surface conditions than in fine weather and dry surface conditions. The differences were statistically significant. In fog, there was found no effect of road lighting during darkness. However, there were indications on a daylight safety effect during fog, possibly due to guidance from light poles. The results from the studies described in this thesis give a basis for increasing the application of road lighting as a traffic safety measure worldwide. Cost – benefit calculations indicate that road lighting is one of the most efficient road safety measures available. However, the energy consumption related to road lighting is a problem that must be considered. The great challenge is to reduce the energy consumption as much as possible without reducing the safety benefit too much. Future road lighting will probably be of the adaptive type, and it will be essential to know how the safety effect varies according to traffic and weather conditions and how it varies with the road lighting level and the quality of the lighting. The thesis answers some question about the safety effect during different weather conditions. There is, however, too little information about safety effect related to varying road and traffic conditions. A more serious lack of knowledge is that we do not know how the safety effect varies according to the lighting level. It is not possible to balance the energy consumption and the safety effect as long as this relationship is not known.

Full textAbstract:
The purpose of this Master thesis in Vehicle Engineering, is to study the road unevenness relation to road safety. The long term objective is to be able to prioritize which road section that is in the need of repair and maintenance prior to other road sections. This study focus on how close to an acceptable safety limit the vehicle is handled when it is run over different road surfaces. This applies to straight road sections as well as cornering, where the road surface is uneven and bumps/pits occurs. No driver behaviour or random actions are analysed but these aspects will be included in the overall discussion. The method to analyse this is through computer simulation. From a Volvo S40 a computerised vehicle model has been developed in Matlab and the effect of different road unevenness has been implemented and analysed. Forces that are generated by the unevenness of the road are compared with the normal forces that a driver needs to correct the course based on the friction between tire and road surface. On this basis, a margin to the risk of losing the grip can be estimated. In this way it can be interpreted how a road section contributes more or less, compared to another section, to whether the vehicle is closer to a safe limit from a vehicle dynamic perspective. The vehicle model has been analysed at a speed of 70 km/h with the simplification that the irregularities can be described by sinusoidal shapes. For larger bumps or dips in the road the results show that both front and rear tires can absorb side forces so that stability can be achieved. If the grip would deteriorate due to gravel, ice, etc. there is a risk that the vehicle loses steering control and/or cord leading to damage of the tyre and consequently an accident will occur. For the analysed road unevenness in the form of bumps and pits the tires do not have any ability to absorb required side forces during an avoidance manoeuvre when travelling over the road due to the tyre model used. It is therefore important that a section with varying unevenness are analysed to determine a maximum speed so that the control of the vehicle during the whole distance can be maintained regardless of whether control needs to be done in connection with the unevenness. A recommendation of future work in this area is to develop this model to make it more robust and to update the input data with relevant data for one today representative car and to carry out a more detailed full-scale modelling with also lateral simulations. If the model was verified with measured normal forces for a test car that has travelled over various bumps and pits, this would also be valuable to confirm the validity of the model. There would also be improvements if available road profile is implemented in the analysis so that realistic examples can be analysed for better real-world analysis.<br>Arbetet avser att, ur ett fordonsdynamiskt perspektiv, studera vägojämnhetens påverkan på trafiksäkerheten. Det långsiktiga målet med arbetet är att kunna prioritera vilka vägavsnitt som behöver repareras före andra. Studien behandlar hur nära en acceptabel säkerhetsgräns fordonet ligger rent fordonsdynamiskt när den färdas över vissa vägunderlag. Det gäller såväl på raksträckor som vid kurvtagning där vägytan har större ojämnheter (svackor) och gupp eller gropar. Metodiken som har använts är datasimulering. Utifrån en Volvo S40 har en fordonsmodell byggts upp i Matlab och inverkan av de olika typerna av vägojämnheter har sedan analyserats. Krafter som skapas från vägojämnheter jämförs sedan med de normalkrafter som en förare behöver för att korrigera kursen utifrån friktionen mellan däck och vägbana. Utifrån detta kan en manövermarginal uppskattas och på så sätt kan tolkning ske hur vida ett vägavsnitt bidrar mer eller mindre, jämfört med ett annat avsnitt, till att fordonet befinner sig närmare en trafiksäker gräns rent fordonsdynamiskt. Analysen har gjorts utifrån antagandet att fordonet har färdats med en hastighet på 70 km/h över de olika vägprofilerna. För större ojämnheter och svackor i vägbanan visar resultaten att både fram och bakdäck kan uppta de nödvändiga sidkrafterna för att stabilitet skall upprätthållas då goda vägförhållanden råder. Men skulle greppet försämras exempelvis av grus, halka etc. så föreligger risk att fordonet tappar styrförmåga och/eller får sladd. En begränsning i denna studie är att inga förarbeteenden eller slumpmässiga händelser kommer analyseras men däremot kommer dessa tas med i den övergripande diskussionen. Dessutom har ojämnheterna antagits vara beskrivna av sinus-funktioner och däcken har beskrivits av en modell som ej tar hänsyn till laterala egenskaper. För att kunna bestämma en maximal hastighet under vilken en kontroll över fordonet kan upprätthållas under hela sträckan oavsett manöver är det av vikt att ett vägavsnitt med varierande ojämnheter analyseras. För att vidareutveckla denna modell och göra den mer robust och aktuell rekommenderas att indata uppdateras med relevanta data för en idag representativ bil samt att modelleringen genomförs i full skala. Om modellen kan verifieras med uppmätta normalkrafter för en bil som har färdats över olika ojämnheter eller gupp vore det värdefullt. Att även implementera uppmätta vägprofiler så att realistiska exempel kan analyseras skulle dessutom ge ännu mer verklighetstrogna analyser.

<p>This project was about develop a concept for next generation weather station and was</p><p>assigned by Bushnell, Kansas U.S. The project was appropriate for the students since it</p><p>would involve product development with both visual design and engineering. For the</p><p>reason that the initiator was located in another country, the students got an offer of being</p><p>positioned at the consultant firm; Epsilon in Gothenburg.</p><p>This project is about developing an innovative product as the next step of their evolution;</p><p>a portable Wi-Fi household appliance that keeps the user up-dated with weather forecasts</p><p>as well as news and other desirable info. This next generation weather station shall be</p><p>transboundary by offering more than traditional weather forecasts. Through its direct</p><p>connection to Internet it shall display and capture customizable data such as news, traffic,</p><p>sports (scores, news and highlights), photo and video content to name a few. The user</p><p>shall be able to get “data at-a-glance” in a fun user-friendly, low maintenance approach</p><p>while keeping the simplicity of the older products.</p>

Full textAbstract:
DC United is one of Major League Soccerâ s most decorated franchises, yet it still plays its home games within the crumbling confines of RFK Stadium. This structure and the surrounding parking lots sit vacant for most of the year, though they occupy a prime site along the Anacostia River. In this project, I am proposing to incorporate a new metro station, transit hub and commercial development into the design of a stadium for DC United along the northern portion of the site. By providing services and amenities that do not currently exist in this part of the city, this endeavor could be a viable year-round resource for the community.<br>Master of Architecture
