Suite of Roads is an orchestral suite comprising of two contrasting movements. This work explores and develops my original musical ideas in regard to the nature of roads and their role in connecting individuals and societies. Each movement follows the musical narrative of a hypothetical road, the first being titled "To" and the second being titled "From." All of my musical ideas evolve out the lucid imagined experience of traveling along one of these roads-away from a musical "home" to an imagined destination, then making a return trip along a very different yet equally vivid route. The musical ideas in the first movement are vast, spacious, and wandering, whereas the second movement is quick and vigorous. True to the concept of departure and return, the musical material presented at the beginning of the first movement briefly reappears at the end of the second movement, thus signaling the end of the musical journey and the final return home.

Abstract:

Stormwater runoff from highways can contain pollutants such as suspended solids, nitrogen and phosphorus, organic material, and heavy metals. Growing awareness leading to regulatory requirements reflects the need to protect the environment from highway runoff effects. The management practice discussed in this study is the use of vegetated roadsides. The primary objective of this research is to document the potential treatment values from vegetated roadsides typical of common rural highway cross sections in two Texas cities: Austin and College Station. Three sites in each city were examined in this study over a 14-month monitoring period. No significant difference between the edges of pavement pollutant concentrations were observed at any of the research sites in the two study areas. This allowed for direct comparisons of the vegetated roadsides and their associated site characteristics such as annual daily traffic (ADT), dry period, and rainfall intensity. The scatter plots of College Station data show that concentrations of total suspended solids (TSS), total Pb, and chemical oxygen demand (COD) in runoff are dependent on the antecedent dry period and decrease with longer dry periods. The results show that pollutant concentrations are not highly dependent on ADT. However, the results show that the number of vehicles during the storm (VDS) was evaluated and accepted as a satisfactory independent variable for estimating the loads of total Pb and TSS. The results of correlation analysis show that the concentrations of total Pb and chemical oxygen demand are significantly correlated with TSS levels. The findings indicate that nitrate concentrations in runoff is most dependent on the average daily traffic using the highway during the preceding dry period as well as the duration of that dry period. Sites 2 and 3 in College Station are steeper but outperformed Site 1 which has much flatter slopes. This could be accounted for by the poor vegetative cover (brown patches) at Site 1. In the Austin sites, the permeable friction course appeared to have a significant impact on the quality of runoff leaving the road surface. On the whole, the results of this study indicate that vegetated roadsides could be used as a management practice for controlling and treating stormwater runoff from Texas highways.

Abstract:

The Wakatipu Basin lies within the Otago Schist belt, and aggregates derived from the schist do not meet New Zealand basecourse specifications. This study comprises engineering geological investigations of the roading aggregate with the objective of identifying potential aggregate source areas which comply with specifications. Five aggregate sources, two glacial and three post-glacial, have been identified, and their geology related to aggregate quality. A survey of existing aggregate quarries confirmed the sub-specification quality of schist derived roading aggregate, and that the highest quality roading aggregate of the Basin is produced from exotic glacial transported graywacke. A graywacke rich aggregate source area of Kame terraces was investigated. Investigations included mapping at scales of 1:10 000 and 1:1 500, and the excavation of test pits. A geotechnical testing programme concluded that the Kame terrace source area was capable of producing roading aggregate for basecourse, and is comparable with the highest quality roading aggregate of the Wakatipu Basin. Subsequently, the Queenstown - Lakes District Council has developed an aggregate quarry within the Kame terrace source area.

Full text

Abstract:

A driveway is needed to get to and from a property. Sometimes there are no opportunities to locate the driveway on the own property. One possibility is to use someone else´s land for locating a driveway in exchange for compensation. The purpose of this study was to examine how the compensation is determined for both long and short driveways outside zoning by doing a case study and compare the result with the various reimbursement rules. The work also addresses the different methods of profit distribution and how they are applied in practice. The conclusion from the case study is that the average value principle is used the most because it is expected to be similar to the case in “normal voluntary agreement”, which is the purpose with the reimbursement rules. To make the reimbursement correspond with the value decrease of the waiver property, adjustments are made on the average value in different ways. The cadastral files to the case study did not match the purpose completely. Therefore, the result can be questioned, but another conclusion drawn from the case study is that in the cadastral files no one discusses about the size of the driveway. It may be that the size of the road is not considered to be a problem or that there is a well-tested method to solve this problem.
För att ta sig till och från en fastighet behövs en utfart. Det är dock inte alltid möjligt att placera utfarten på egen fastighet. Då finns möjligheten att mot ersättning nyttja annans mark för utfart. Syftet med denna uppsats var att undersöka hur ersättningen bestäms för både långa och korta utfarter utanför detaljplan genom att göra en fallstudie och jämföra resultatet med de olika ersättningsreglerna som finns. Uppsatsen berör också de olika vinstfördelningsmetoderna och hur dessa tillämpas i praktiken. Slutsatsen av fallstudien är att den vinstfördelningsmetod som används mest är genomsnittsvärdeprincipen för att den förväntas likna fallet vid ”normal frivillig överenskommelse”, som också är syftet med ersättningsreglerna. För att ersättningen ska stämma överens med marknadsvärdeminskningen på den upplåtande fastigheten justeras genomsnittsvärdet på olika sätt. Förrättningsakterna som användes till fallstudien stämde inte överens med syftet helt. Därför kan resultatet ifrågasättas, men ännu en slutsats som dragits utifrån fallstudien är att i förrättningarna är det ingen som diskuterar storleken av utfarten. Det kan vara för att vägens storlek inte anses vara ett problem eller för att det finns en väl beprövad metod för att lösa detta problem.

Full text

Abstract:

A fauna passage is a way for animals to cross roads separated from the traffic. In Sweden, there are an unknown number of passages with different functions and appearances. These passages would, with the question “Which fauna passages can be found in Sweden, and how well do they work?” as a base, be compiled in a comparable way. This would be done with a number of questions asked to the different regions of Vägverket. The essay was delimited to only include ecoducts, animal bridges, landscape bridges, animal gates, tunnels for small animals, shore passages and fence openings.

Most of Vägverkets regions had poor documentation of their passages and lacked the time to improve it. Most questions could only be answered for the region in general, and not for every passage, which forced us to change our way of account. In the end, most of the questions were answered by every region, even though it had not seemed possible earlier. Almost all regions also accounted for all their pas-sages in tables and with selected pictures to illustrate the passages.

The compiled result showed that there were no ecoducts in the country and the passages directed to otter was clearly dominating. There were only a few passages constructed for larger animals, such as deer and elk, but those existing were better documented and followed up, than the smaller passages. It is likely that a lot of animals use regular road bridges and tunnels, but there is no documentation of this.

The smaller passages are often planned in a simplified way, sometimes only through discussion in field. This often gave a fully sufficient and functional result, but there are examples of passages which did not function alright due to simplify-ing and inadequate planning.

The passages varied in shape in the different regions, which all seemed to prefer certain kinds. It was not clear from the basic data if this depended on climate dif-ferences between the regions, or if it simply was a question of taste.

Abstract:

Placing security cameras in buildings, finding good locations for cameras to enforce speed limits or placing guards to defend a border are some of the problems we face everyday. A nation that wishes to defend its border with armed guards wants to be sure the entire border is secure. However, hiring more guards than necessary can be costly. A start-up company moving into a new building wants to be sure every room in the building is seen by some security camera. Cameras are expensive and the company wants to install the smallest number of cameras; at the same time the company wants to be sure the building is secure. These problems, and many other visibility type problems, are not easy to solve in general. In some specific cases, optimal solutions can be obtained quickly. In general, finding an optimal solution may take a very long time. The original results of this thesis address some of these problems. We show some positive results for solving some of these visibility problems. We also give some negative results for some of these problems. These negative results are useful because they tell us that we are unlikely to find a fast algorithm to solve a particular problem optimally.

Full text

Abstract:

There is increasing concern about the adverse effects of the road network on wildlife. The impacts of roads in the ecological landscape include habitat loss, habitat fragmentation and habitat degradation. These interrupt and modify natural processes, altering community structures and population dynamics. The large number of animal fatalities from road traffic accidents is also of concern. Only limited work has been carried out to investigate the intensity of these effects in the UK landscape. This study investigates the effects of roads on both small and large mammals and reviews mitigation measures that have been installed to ameliorate some of these effects. Roads of all sizes present a significant barrier to animal movement and they affect it in specific ways. Movement of small mammals is inhibited by lack of cover and the hostile road surface, whilst fragmentation of the road-verge by highway-related structures, impedes dispersal and compromises the benefits of connectivity often ascribed to such areas. Large animals, which use roads to travel through their territory, are more likely to be struck by traffic and are therefore, more directly affected by traffic-intensity. There is room for further mitigation to reduce the worst of the road-related impacts.

Brito, Lelio. "Design methods for low volume roads." Thesis, University of Nottingham, 2011. http://eprints.nottingham.ac.uk/12081/.

Full text

Abstract:

This thesis is concerned with producing a simple method to design low volume roads (LVR) by means of a rationale which accounts for permanent deformation development in granular layers. Rutting is regarded as the main distress mode in unsealed and thinly sealed pavements. Hence, it is desirable that it be analytically approached rather than empirically, as in most design methods. The overall aim of this PhD thesis was to look into the behaviour of in-service roads and from a newly developed process, to advance, in a systematic manner, the elements required to produce a simple mechanistic design procedure. The study took as its basis an assessment of the proximity of the stress distribution in the pavement to the material’s failure envelope. After a literature review on unbound granular materials mechanical behaviour and on low volume roads pavement design methods, Chapters 4 and 5 discuss full scale trials carried out in Scotland on typical forest roads. The overall goal of the trials carried out within the Roads Under Timber Transport project was to establish the effect of weather and seasonal effects on the rutting of forest roads and to improve their performance while enabling the roads to be economically constructed and maintained. It appears that most of the rutting occurring in the sites surveyed came shortly after their construction/resurfacing, leading to the assumption that workmanship may be a highly important variable. Lack of compaction of the layer could be one of the likely reasons for the high initial rutting rates. Establishing the effect of weather on rutting further to the existing knowledge was, however, difficult to achieve; this was mainly due to the difficulties faced in monitoring traffic conditions. A newly developed method was needed to quantify permanent deformation development due to wandering traffic on a non-level pavement; this was achieved by the use of wheel path areas, and seemed to be a way forward in the analysis of rutting in unsealed roads. Accelerated pavement trials are reported that aimed to evaluate the performance of aggregate under soaked conditions and the relative pavement deformation caused by different timber haulage vehicles. A road segment simulating a standard forest road section was constructed in a purpose-built facility located at the Ringour Quarry facility. Ten different trials were carried out combining three different aggregate materials and five types of vehicles. Tyre fitment, axle configuration and tyre pressure were assessed and demonstrated to play an important role on the study of rutting development. Conclusions drawn from the results suggest that management of the tyre inflation pressure and axle overload may be one of the most economic means of managing pavement deterioration in the forest road network. A mechanistic analysis of a variety of unsealed pavements was carried out in Chapter 6; and the newly proposed methodology is described in Chapter 7. With changing loading conditions – e.g. as a consequence of the introduction of Tyre Pressure Control Systems and super single tyres – more detailed analyses are required, so that their effect can be analytically assessed. Then an analytical method is introduced for evaluating the stress-strain condition in thinly surfaced or unsurfaced pavements as typically used in LVR structures. It aims to improve the understanding of the effect of tyre pressure and contact area in regard to permanent deformation. To achieve this, several scenarios were modelled using Kenlayer software varying aggregate material, thickness, stiffness, tyre pressure & arrangement. The results usually show a fairly well defined locus of maximum stresses. By comparing this stress envelope with failure envelope, conclusions could be established about the more damaging effect of super singles over twin tyres and, likewise, the greater damage inflicted by high tyre pressures compared to that incurred by lower tyre pressures. Finally, the framework of the proposed method contributes to LVR pavement design procedures mainly due to its simplicity. It still treats the pavement analytically, permitting a more fundamental description of the behaviour of granular layers than in simple linear elastic analysis, but by simplifying the elasto-plastic analysis for routine use it thereby reduces demands of material characterization and computational skills, thus increasing its utility in practical application.

Abstract:

Soil loss was measured on selected unsurfaced forest roads in Idaho and Colorado, using a rainfall simulator. From the data collected, both flow-induced and raindrop-induced interrill erodibility parameters were determined. Each forest road site consisted of one 5 m² and on 1 m² plot which simultaneously received artificial rainfall. Soil loss from the small plots was attributed solely to detachment by raindrops. The larger 5 m² plots may include some flow-induced soil loss. A method was developed to apportion the erosion from the 5 m² plots between flow-induced and raindrop-induced soil loss. Four different models of raindrop-induced erodibility and three different models of flow-induced erodibility were compared. Those considered most applicable to forest road conditions were suggested for further use in an erosion model for disturbed forestlands. This study serves an an important contribution in developing such a model by providing initial estimates of interrill erodibility parameters for forest road conditions.

Abstract:

This paper presents the phenomenon of private co-financing of national roads. The theory section show that there is currently no statutory regulation of private co-financing. However a regulation is proposed in a supplement to existing planning and building law (2010:900). The case studies present examples of how private co-financing of national roads works in practice. In these cases, private co-financing is regulated by the development agreement. The analysis points out that problems can arise when the parties in a development agreement are not equal.
I denna uppsats presenteras fenomenet privat medfinansiering av statliga vägar. I teoriavsnittet visas att det idag inte finns någon lagreglering av privat medfinansiering. En reglering föreslås dock i ett tillägg till gällande plan- och bygglag (2010:900). I fallstudier presenteras exempel på hur privat medfinansiering av statliga vägar går till i praktiken. Där framkommer att privat medfinansiering regleras i exploateringsavtal. Analysen visar bland annat på att vissa problem kan uppstå då parter i ett exploateringsavtal inte är jämbördiga.

Abstract:

Traffic congestion is a common problem in larger cities. Time consuming queues affects both the humans and the environment. This report investigate show to improve the traffic flow in a future scenario where only autonomous vehicles are present. The methodology was to construct traffic networks on routes where congestion is a problem. This was done with three different Stockholm routes. The networks were transformed into graphs and then the maximal flow was calculated by Edmond Karp’s flow algorithm. The result proves that this type of route planning is a concept that can be used in future studies to decrease congestion. This is due to the fact that the flow increase was much larger than both the increase in travelled distance and time.
Trafikstockning är ett vanligt förekommande problem i större städer. Tidskrävande köer påverkar både människan och miljön. I denna rapport studeras hur man kan förbättra trafikflödet i ett framtida scenario där endast automatiserade fordon är tillgängliga. Metoden var att konstruera ett nätverk utav vägar där trängsel är ett problem. Detta gjordes för tre olika rutter i Stockholm. Nätverken transformerades sedan till grafer och det maximala flödet beräknades med hjälp av Edmond Karps flödesalgoritm. Resultatet visar på att denna typ av ruttoptimering skulle kunna användas i framtida studier för att minska trafikstockning i och med att flödesökningen var betydligt större än både ökningen i avstånd och tid.

Abstract:

Thesis (M.Eng.)--Massachusetts Institute of Technology, Dept. of Electrical Engineering and Computer Science, 2000.
Includes bibliographical references (leaves 36-38).
We have developed a wireless sensor package to instrument roadways for Intelligent Transportation Systems. The sensor package counts passing vehicles, measures the average roadway speed, and detects ice and water on the road. Clusters of sensors can transmit this information in near real-time to wired base stations for use controlling and predicting traffic, and in clearing road hazards. The sensor package draws a maximum time-averaged current of 17 tA from an internal lithium battery, allowing it to operate in the roadbed for at least 10 years without maintenance. The nodes cost well under $30 to manufacture, and can be installed without running wires under the road, facilitating wide deployment. Unlike many other types of traffic sensors, these sensors count vehicles in bumper-to-bumper traffic just as well as in widely separated traffic. The devices detect vehicles by detecting the perturbations in the Earth's magnetic field caused by the vehicles. They measure this perturbation using an anisotropic magneto-resistive magnetic field sensor. The radio transmitters in the sensor are frequency-agile, and the sensors use a randomized sparse TDMA protocol, which allows several transmit-only devices to share a channel. The sensor package includes a custom-designed, compact, broadband, inexpensive printed circuit microstrip antenna for the 915 MHz U.S. ISM band. We built a prototype sensor package, and installed it in a pothole in a city street. We used the sensor to monitor the traffic flow rate during free-flowing traffic and a traffic jam.

Abstract:

This study evaluated the success of recently revegetated roadsides in Tucson, Arizona. The primary objectives of this study were to (1) evaluate a sample of revegetated roadsides by assessing site condition and comparing existing vegetation to the original seed mix; and (2) develop recommendations for appropriate revegetation practices for use in Tucson. Density data were collected at 20 locations using belt transects to derive species information such as origin, vegetative life-form, and invasiveness. Results indicated that the study sites had greater proportions of plant material not specified in the original construction documents than specified plant material. Of the specified species, creosote bush, desert senna, and triangle-leaf bursage had the highest rates of establishment while brittlebush, globemallow, shrubby buckwheat, and fourwing saltbush provided the most vegetative cover. Several non-specified species exhibited successful establishment on many study sites, while some species rarely or never appeared in the study area despite frequent specification.

Full text

Abstract:

Exotic plant species can be a serious threat to native ecosystems and the human economy. They have often been found to grow in greater abundance along roadsides, and seem to use them as corridors of invasion into the surrounding habitats. This study sought to determine whether there were any relationships between the distribution of exotic plant species and adjacency to roads in southern Illinois. To test this question, I conducted two research projects. For the first project, I ran transects from active and abandoned roadsides into adjacent forest interiors to collect data on the presence and abundance of exotic species. Along most roads, exotic species richness declined with increasing distance from the road. In most cases, abandoned roads were more likely than active roads to have a high abundance of Lonicera japonica and Rosa multiflora. For the second project, I collected geographical data for exotic species from field studies, herbaria records, and literature records, and compared them based on distance from the nearest road, family composition, and life form composition by both number of species and number of records. On average, herbaria records were farther from the road than field studies. Composition of families and variety of life forms were not significantly different when comparing by number of species, but were significantly different when comparing by number of records.

Harvesting Energy stands alone as one of the most promising techniques for approaching the global energy problem without depleting natural resources. Energy harvesting technologies from road infrastructure is a new research territory that encompasses technologies that capture the wasted energy occurred at pavements, accumulate and store it for later use. Their most enticing characteristic is that they already offer extended paved surfaces. Paved surfaces with conductive pipes, PV sound barriers, nanomaterials or Phase Change Materials, piezosensors and thermoelectrical generators and induction heating technique are just the most updated representatives. Their outputs can be listed as production of electric energy and district heating and cooling, deicing surfaces or powering wireless networks and monitoring pavements conditions along with the enhancement of their self-healing process. The objective of this thesis is to review them and identify their strong and weak points. The three Green Roadway Concepts that shaped, proposed and implemented, theoretically are identical for the long- and short-term challenges that they meet. Their forthcoming future is here and only their in-situ implementation can prove their viability and prominence.

Abstract:

The main purpose of this report, is to evaluate feasibility of using The Global Positioning System as an aiding tool for vehicle state estimation based on nonlinear techniques, and to develop a potential solution to the road bank angle problem. Previous work within the CEmACS project, includes development of a general nonlinear observer for lateral and longitudinal velocity, and an augmentation in the form of road-tire friction adaptation. Because the existing solutions have been shown to lack robustness with regards to certain disturbances, such as road grade and road bank angle, it has been stated that the estimation scheme should be upgraded, so that these disturbances can be accounted for. By including GPS velocity or a or a roll rate gyro measurement in the observer feedback loop, the possibility of detecting previously inobservable quantities is gained. In simple terms, evaluation of feasibility corresponds to demonstrating improvements and limitations of new solutions, using relatively crude methods in the test procedures. Problems related to the above mentioned task, are approached by means of signal processing and control theory. Following an intuitive sequence of operations, the report presents GPS theory and results first, as this lays the foundation for all subsequent results. Methods used comprise simple differentiaton, rotational kinematics and discrete filtering. Secondly, theory and results related to nonlinear observers, with focus on GPS aiding, are examined thoroughly. Lyapunov theory, known from control engineering, is used to evaluate stability, while data from simulations and actual vehicle tests is used to show how a new observer scheme can improve existing solutions. Before the most important results are presented, something should be said about their accuracy and significance. It has already been pointed out that the methods used are not based on optimality requirements, and consequently the results are best viewed as indicators of potential, rather than absolute solutions. This is especially true for the GPS velocity calculations, which are based on differentiation of position measurements; generally not a desired approach. In this report, it is firstly shown that GPS position measurements can be used to compute receiver velocity in the body-fixed coordinate frame. While this is a crude approach, resulting in relatively poor signal to noise ratio, it is easily implemented on low-level equipment. It is also shown that it is possible to use these velocities as measurements in a nonlinear observer structure, slightly modified from previous solutions within the CEmACS project. By doing this, accurate estimates of road grade and bank v angle are achieved, so long as these vary slowly enough. Stability of the observer is not proven in the general sense, but it is shown that it can be made stable through realistic assumptions and gain selection. Stability is further demonstrated through the use of data sets from actual vehicle tests. Secondly, a mathematical model of roll dynamics is combined with a roll rate measurement to create the possibility of detecting road bank angle. This is done by the now familiar nonlinear observer approach. Usefulness is demonstrated by simulations, but no stability proof is presented. The main conclusion is that it is feasible to use GPS aiding to account for robustness problems in a vehicle state estimation scheme, and that the inclusion of a roll rate measurement opens up possibilities for cheap bank angle detection. A direct implementation of results presented in the report may not be ideal, but the fact that the system works for a large set of conditions, suggests that it is worthwhile to develop it further. This is especially true when it is assumed that GPS receivers will become an integral part of new vehicles in the near future. Refinements and upgrades can be made in the form of more advanced GPS technology, new parameter estimation techniques and integration with the road-tire friction adaptation scheme.

Abstract:

Current available methods for the design of unpaved roads, with and without geosynthetics, were used for sixteen full-scale test sections which were constructed at the Bothkennar Soft Clay Site, Airth, Scotland. The full-scale trials consisted of twelve pavements including geosynthetics and four control pavements incorporating two types of aggregate and two design life expectancies. The test pavements were instrumented to monitor the transient stress and strain distribution, permanent strain distribution, geosynthetic temperature and ground water level during the trafficking operation. Traffic loading was provided in two stages by a standard road-going vehicle. The vehicle used for Phase One applied an 80kN axle load and in Phase Two a 126kN axle load. Failure of the pavements was defined as a rut depth of 150mm. The passage of 2115 axles resulted in failure of three sections and significant deformations in many others. Back-calculation to compare predicted and measured performance was performed and hence the existing design methods were critically assessed. Where possible the measurements obtained from field trials were used to examine the assumptions made within the design methods. The existing design methods were found to be essentially static in approach and did not model transient stresses and strains or permanent strain development adequately. Pointers towards a new approach ensuring strain compatibility between the elements of the system are suggested. This should enhance the ability of the engineer to assess the value of differing products used in this application.

Abstract:

Bitumen emulsion mixtures, or cold mix, offers certain advantages over hot bituminous road mixtures in terms of potential cost savings, environmental factors, energy savings and easing of logistical difficulties inherent with hot mix. For these reasons, they are currently used in a number of regions including the United States of America, Continental Europe, Scandinavia, Southern Africa and Australia. However, cold mix has not been seriously evaluated or utilized in the UK until comparatively recently. This is due to the slow rate at which it builds strength or cures and its susceptibility to rainfall, particularly during this curing period. The overall aim of this research was, therefore, to study the behaviour of cold mix in terms of mechanical properties and the mechanisms involved in emulsion breaking and mixture curing to gain an insight into how performance may be improved. Mechanical properties were shown to be affected by a number of parameters, including binder grade, void content, curing time and additives such as cement. Fatigue tests showed that without cement, the performance in-situ of cold mix would be very poor. Pavement design calculations revealed that, with cement, emulsion mixtures could be expected to perform similarly to equivalent hot mix. Field trials have indicated that cold mix can be manufactured using conventional hot mix plant and laid using similar techniques. However, problems are still to be overcome in terms of the control of mixture composition and laying in adverse weather conditions. Fundamental tests have shown that emulsion droplet coalescence (which is an essential part of the curing process) was affected by pressure, bitumen type, emulsifier level, cement and temperature and that cement can cause emulsion charges to become more positive (or less negative) but other parameters had no effect on charge. It was also proved that cement can cause bitumen emulsion to set completely and that the residual binder has an increased viscosity compared with unmodified binder. This was shown to be due to the formation of a composite bitumen cement binder.

Abstract:

This paper discusses the conflicts between some cultural practices of the Midzichenda (i. e. divination, healing and witchcraft) and the Kenyan Law. For decades, diviners and healers have been misconceived and condemned wholesale as `witchdoctors´, `wizards´ or `witches´. This misconception has seen many innocent diviners and healers mercilessly arrested, hurriedly arraigned in court, heavily fined and (or) eventually imprisoned, and their paraphernalia confiscated and finally destroyed by the state. The paper calls for proper understanding of the intricate belief in and practise of divination and healing vis-a-vis witchcraft and proposes ways which could help solve the conflicts.

Full text

Abstract:

During strong winds, drifting snow causes problems on roads in many harsh winter climate countries. Increased snow-removal costs, reduced access and safety problems are typical results of excessive snowdrift sedimentation and bad visibility along many roads in the exposed regions.

The objective of the study is to enhance knowledge on drifting snow behaviour on roads and to develop design criteria for better road construction in mountainous areas and other areas where frequent snowfall and strong winds occur. The study is focused on road cuts, because road sections with terrain cuts are the most vulnerable both concerning visibility and snow depositing on the road. The study is mainly based on CFD (Computational Fluid Dynamics) and field measurements. Field studies were carried out in both Norway and Iceland, and include snow surveys, wind measurements and a visibility registration. A wind tunnel study on snow drifting around a model avalanche dam is also a part of the thesis.

Wind flow in road cuts was simulated and the resulting wind speed distribution and flow pattern were compared to snow surveys. On basis of this comparison and by considering experimental relationships between wind flow and snow drifting, new design principles were proposed.

An important result of the study is the distinction between wind flow and snow drifting in gently sloping road cuts and in steep road cuts, respectively. Wind and snow drifting in gently sloping cuts and on leeward facing hillsides can usually be described as a two-dimensional flow. On the other hand, steep road cuts generally create a vortex moving parallel the road, and the resulting flow pattern must be described in three dimensions.

Results for gently sloping road cuts suggest that in order to achieve a drift free road, it must be placed downwind of the equilibrium snowdrift surface. This implies that a considerable speed up in the wind has to occur over the road embankment to facilitate snow erosion from the road surface. A statistical method to predict equilibrium snowdrift surfaces by using terrain information only is proposed. The model is based on weighing terrain slopes, and creates a streamlined surface to imitate the shape of the equilibrium snowdrift surface.

For steep cuts, a design that features an expanded cut width at both ends of the cut was tested. The design increases the speed of the transverse vortex under the cut edge, and generates less turbulence than a straight cut, which is believed to have a positive effect on the visibility. The proposed design also moves the critical low speed areas away from the road, and should therefore result in less snow accumulation on the road.

It is concluded that plain wind flow simulations are a helpful tool to learn about snow drifting on roads, and can be used to test the quality of a proposed design. The suggested design principles for road cuts are promising for full scale testing.

Abstract:

Roads and routeways, whether engineered or created ad hoc, create a dynamic element to the lives of those who use them and facilitate many features of day to day life. As such they have been a fundamental and powerfully ideological part of human existence. This thesis shows the causes and effects of road and transport network development in County Durham in the period from 1530 to 1730, and challenges the commonly made assertion that routes changed little from the Medieval period until the Industrial Revolution. Drove routes, lead mining routes and the infrastructure of re-used Roman roads are viewed holistically and considered as individual and integrated networks over a broad time period. These networks are analysed and compared using quantitive spatial analysis and GIS (Geographic Information System) techniques to examine which factors were pivotal in the creation of each road or routeway system. In addition, factors such as consumption patterns, shifts in population and funding mechanisms are drawn upon to examine roads as artefacts and cultural markers. Thus the roads and the roadscapes are used to study the identities of those who used them. A trial of dating techniques with which to date roads, with the use of optically stimulated luminescence (OSL) infra-red stimulated luminescence (IRSL) and radiocarbon dating, was also completed. It will be shown that different factors influenced the placement of the different routes. Distance and slope being of prime importance for the Roman network; land use type, distance and visibility for the drove routes and land use type and slope for the lead routes. These routes formed part of an holistic network which, through using different network types for different tasks and purposes, gave strength to the overall transport system of County Durham. Thus the network helped to drive new aspirations and patterns of consumption, facilitated the exchange of information and fashions and helped to provide new sources of wealth. The connectivity that the roads and routeways brought created a county with greater geographical, cultural and social knowledge that stimulated an increase in class consciousness, in so doing they also provided the means by which these new ideals and ideas could be expressed.
