Abstract Rural roads are the backbone to any country and is always a key for sustainable development. Rural roads are often considered as an entry point for poverty alleviation and employment generation. Rural Connectivity is achieved in different levels of hierarchy through a traditional hierarchical structure – National Highways, State Highways, Major District Roads, Other District roads and Village roads for achieving a long term objective of adequate road communication in India. The policies for connectivity of villages are followed mainly by population criteria. The connectivity through hierarchy is to be planned from the travel behaviour and activity generation, which depends on various profiles like demographic, socio – economic profiles, facility profile and the impedance values. This methodology proposes a strategic model that characterizes the varying profiles in an area and accounts the demand based on these profiles. An integrated model based on clustering analysis and GIS has been formulated for assessing the demand potential and thereby giving an orientation to a hierarchal rural road network configuration. This promises to be scientific tool as it was validated with the existing higher order road network such as National and State highways in the region. The study has been attempted on Medak district of Telangana state.

Abstract. Road network functional hierarchy classifies individual roads into several levels, for efficient traffic management and road network generalization purposes. Automatic and semi-automatic road network extraction methods exist, but the generated products normally lack information on its functional hierarchy. This paper presents a methodology for automatically retrieve functional hierarchy for an OpenStreetMap derived road network from Floating Car Data, obtaining evenly distributed (e.g. for generalization purposes) or dynamic (e.g. to take into account differences in traffic volumes in different moments of the day) classifications. Road network elements are classified in function of vehicle speed values: the class distribution generated with the proposed methodology follows a linear distribution that can be better exploited for generalization purposes. Furthermore, the methodology allows to clearly distinguish different distributions in different moments of the day and days of the week, supporting traffic management activities.

The rigid pavement on many roads is considered as a solution due to the increasing traffic load that requires high performance and durability of the road construction. However, the implementation of rigid pavement takes a longer time to reach its concrete strength until the road operation. Some industries have developed pavement from precast concrete panels to reduce construction time. This paper discusses the comparison of rigid pavement between precast concrete and conventional concrete. Two road sections are Jalan Margomulyo Surabaya using precast-concrete-pavement and Jalan Semarang-Jambu using conventional-concrete-pavement chosen as research objects. Cost, construction time, serviceability, and traffic performance are the four variables reviewed in this study analyzed using the Analytical Hierarchy Process (AHP) method with considers 15 competent experts as respondents. Based on the analysis shows that a road improvement project by using precast-pavement is more effective and efficient with a score of 58.42 %, while the score of conventional concrete is 41.58 %.

Full textAbstract:
The primary purpose of a road hierarchy is to ensure that appropriate management, engineering standards, and maintenance practices are applied to a road on the basis of its function. A hierarchy also enables more efficient use of limited resources by allocating funds to those roads that are in greater need and for which the costs are better justified. Studies were recently completed to arrive at a classification system for a wide range of low-volume roads covering rural municipalities and forestry organizations. Results are presented of an extensive literature search and the process and methodology developed to arrive at acceptable standards for various stakeholders relative to a classification system and geometric design and maintenance standards for low-volume roads. Five road classifications are derived for low-volume roads, including functional and road characteristics, to assist in classifying each road in a network. Also included for each road class are guidelines for geometric standards that relate to design speed, cross-sectional elements, and horizontal and vertical curve requirements for flat, hilly, and mountainous terrain. These standards were derived with reference to existing standards, engineering experience, and resources available to a road agency. Each classification has a set of maintenance criteria for both sealed and unsealed roads, covering the key defect types and intervention levels for routine and urgent maintenance.

Roads are the key infrastructure that is needed to support the smooth transportation to improve the condition of the community economy. Along with the passage of time and the use of the road, the road will suffer damage due to natural factors as well as other technical factors, so it takes serious handling efforts from the local government to maintain excellent road infrastructure for the community. In case of road damage handling in some areas still found problems that need to be resolved immediately, one of them is the problem of availability of budget that is not comparable to the level of damage of the road is quite a lot required a method to know the order of the road priority should be addressed immediately. To determine the prediction and priority order of road handling, the Analytic Hierarchy Process (AHP) algorithm is used with consideration of damage, traffic, and economic factors as criteria decision. The result shows that area of Serang city with the value 0.231 (23.1%) as the most priority road to be repaired.

When handling roads, there should not be any roads that are neglected. Due to the limitation of funds, among the roads that have to be maintained, it is not necessarily possible to handle all of them with the same priority. It is necessary to prioritise road handling by considering the conditions and factors that influence its use. Roads that are used more often will be prioritised when it comes to maintenance. The data used in this study consisted of secondary and primary data. The secondary data was obtained from the Public Works Office of Solok City (Database of Solok City Roads, 2017) and Bappeda (RPJMD and RTRW). 8 segments of road were observed. Traffic volume surveys were conducted for 2 x 24 hours. Furthermore, questionnaires were distributed to support the secondary data, and 30 respondents answered. Six criteria were considered: Condition Factors (A), Traffic Volume Factors (B), Economic Factors (C), Policy Factors (D) Land Use Factors (E), and Side Building Factors and Road Complement (F). This study used the Analytic Hierarchy Process (AHP) method developed by Thomas L. Saaty. This method will simplify the complex multi-criteria problem into a priority scale hierarchy. The results of the AHP method analysis were included in a mathematical model as according to Brojonegoro (1991).The results showed that the priority for routine road maintenance was “Traffic Light Pandan - Tanjung Paku” road section (033), the priority for periodic road maintenance was “SMP 1 Simpang Damar” road section (047) and the priority for road improvement in general was “Simpang Sigege - Ampang Kualo” road section (051).a

It is a challenge in the research field of GIS-T and ITS to design a road network model that can well express the full range of transportation information. The existing Multi-hierarchy road network models often have some defaults, such as repeated storage of data, high degree of redundancy, difficult to analyze network, etc. Based on the analysis of image pyramid model and road feature hierarchy, a road network pyramid model has been proposed in this paper. This model has the adaptive ability to express multi-scale information and can descript road network the most detailedly with comprehensive road characteristic of all hierarchies. Low degree of redundancy of spatial and topologic data is another advance of the model. So this model is more suitable for multi-hierarchy analysis of road network.

The article substantiates the relevance of comprehensive comparison of various versions of vehicles for off-road container transportation. Following the need to identify a specific engineering solution for development of a tracked road train, it is proposed to use the analytic hierarchy process designed to solve problems associated with determining the priorities of the multicriteria hierarchical structure of the goal, as well as in the presence of heterogeneous criteria or dimensional and dimensionless indicators. The comprehensive comparison of vehicles for off-road container transportation is based on the hierarchy of the mobility features, which is considered decisive for the choice of the priority variant of the structural design. The objective of the work is to substantiate the choice of a priority engineering solution for structural design of tracked road trains for off-road container transportation based on a scientifically grounded hierarchy of the mobility features. To attain the objective, a consistent solution of the following tasks is suggested as follows: development of requirements for vehicles and for a hierarchy of operational properties; analysis of existing structural design and layout solutions and justification of the choice of alternative solutions (specific designs of tracked road trains); conduct of a hierarchical synthesis of criteria based on the results of expert assessment; identification of the preliminary priority of alternative solutions; obtaining indicators of operational properties by methods of simulation mathematical modelling and/or full-scale mathematical modelling; choice of the priority engineering solution. The article discusses the feasibility of using tracked road trains both for transportation of a single 45-foot container and for simultaneous transportation of two 20-foot containers with a total mass of 61 tonnes. The analysis of the existing versions of structural design of tracked road trains has shown that only a vehicle of SVG-701 «Yamal» series, developed in the 1980s and which is not currently manufactured, can provide such a payload capacity. Existing modern articulated tracked vehicles cannot provide transportation of such goods. Hence, the relevance of the task of determining the priority engineering solution referring to structural design and layout of tracked road trains at the present stage of development of technology. Tracked single-hinged articulated semi-trailer road train and a doublehinged tracked road train are proposed as variants of structural design and layout versions of tracked road trains for off-road container transportation. Based on the analytic hierarchy process, opinions of experts and the hierarchy of operational properties, it was established that the engineering solution referring to double-hinged tracked road train should be prioritised. However, due to the small difference between the values of indicators used to select the options, it is necessary to conduct further studies to determine the values of the indicators of operational properties and to re-compare the options considering the results obtained.

Roads are made up of both pavement and off pavement components. In many cases, only road pavement is subjected to maintenance, leaving out accessory road components even though these components also contribute to overall road performance. Hence, the assessment of both road pavement and road components is vitally important in keeping roads safe and enhancing their overall performance. This study was conducted to know the performance of a select road as well as relevant handling recommendations. The research was carried out on 16 road sections of Magetan Regency, East Java Province with a total length of 85.60 km. The Kabupaten Road Management System (KRMS) Software was used in gathering precise road performance information. Weighting of road components was done using AHP (Analytical Hierarchy Process) while priority handling was determined using Analysis Network Process (ANP) with Super Decision software. A camera was used for the observation of both road and off pavement conditions. From research results after analyzing 16 Straight Line Diagrams, all road segments were in good condition. However, routine maintenance recommendations have been provided after a 16 Strip Map Diagram analysis of road segments. The first priority is Genengan-Lembeyan road segment followed by the Tamanarum-Lembeyan road.

To promote the development of unmanned ground vehicle technologies, it is necessary to design a scientific and reasonable test method. Road is an important part of test environmental elements, and different road conditions can examine the adaptability of unmanned ground vehicles to the environment. Therefore, the scientific calculation of road complexity is of great importance. Previous studies on road are mainly based on the concept of road roughness; however due to the unicity of road feature indicators, road complexity can only be reflected to a certain extent. This paper proposes a new road-feature-based multiparameter road complexity calculation model of off-road environment to show the complexity of road more comprehensively. First, a multi-sensor-based data acquisition mobile platform is established to obtain more complete road data. Then, based on the analysis of road feature, road indicators like three-dimensional scale, average slope, and adhesion characteristics of travelable area are obtained. According to the analysis methods of road roughness, the principle of analytic hierarchy process, and the data collected from off-road environment, the calculation model of road complexity is determined. Finally, by calculating complexities of several cross-country roads, the feasibility of this model is verified, which provides a theoretical support for the scientific calculation and quantitative analysis of different road complexities.

Urban road networks are typical complex systems, which are crucial to our society and economy. In this study, topological characteristics of a number of urban road networks purely based on physical roads rather than routes of vehicles or buses are investigated in order to discover underlying unique structural features, particularly compared to other types of transport networks. Based on these topological indices, correlations between topological indices and small-worldness of urban road networks are also explored. The finding shows that there is no significant small-worldness for urban road networks, which is apparently different from other transport networks. Following this, community detection of urban road networks is conducted. The results reveal that communities and hierarchy of urban road networks tend to follow a general nature rule.

The analytic hierarchy process (AHP), a decision-making method, allows the relative prioritization and assessment of alternatives under multiple criteria contexts. This method is also well suited for road selection. The method for road selection based on AHP involves four steps: (i) Points of Interest (POIs), the point-like representations of the facilities and habitations in maps, are used to describe and build the contextual characteristic indicator of roads; (ii) form an AHP model of roads with topological, geometrical, and contextual characteristic indicators to calculate their importance; (iii) select roads based on their importance and the adaptive thresholds of their constituent density partitions; and (iv) maintain the global connectivity of the selected network. The generalized result at a scale of 1:200,000 by AHP-based methods better preserved the structure of the original road network compared with other methods. Our method also gives preference to roads with relatively significant contextual characteristics without interfering with the structure of the road network. Furthermore, the result of our method largely agrees with that of the manual method.

This paper describes an automated method of constructing a hierarchical road network given a single dataset, without the presence of thematic attributes. The method is based on a pattern graph which maintains nodes and paths as junctions and through-traffic roads. The hierarchy is formed incrementally in a top-down fashion for highways, ramps, and major roads directly connected to ramps; and bottom-up for the rest of major and minor roads. Through reasoning and analysis, ramps are identified as unique characteristics for recognizing and assembling high speed roads. The method makes distinctions on the types of ramps by articulating their connection patterns with highways. Major and minor roads will be identified by both quantitative and qualitative analysis of spatial properties and by discovering neighbourhood patterns revealed in the data. The result of the method would enrich data description and support comprehensive queries on sorted exit or entry points on highways and their related roads. The enrichment on road network data is important to a high successful rate of feature matching for road networks and to geospatial data integration.

Road safety is one of the influential factors in reducing road accidents and the resulting injuries and fatalities. The aim of this study is to determine the safety position of the roads of the Bushehr province based on various quantitative and qualitative criteria. For this purpose, a Multi-Criteria Decision Making (MCDM) approach has been utilized. In this approach, first all criteria influencing road safety in the Bushehr province were classified into main and sub-criteria groups and their weights were obtained using Group Analytic Hierarchy Process (GAHP). Then, the rankings of the Bushehr province roads were calculated through the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS). The results indicate that during the period of investigation, the roads of Bushehr-Borazjan and Borazjan-Genaveh were the best with minor difference and Deylem-Behbahan road was the worst road of this province. In this regard, the criteria of violations/traffic and road facilities contribute more to the results due to their weights. It is clear that continuous evaluation of road safety will have significant effect on governmental policy-makings for improving roads and safety-related actions.

The traffic system is as essential to modern society as the circulatory system to the human body. Road section design is therefore a key infrastructure activity for economic development, and multi-criteria decision-making can provide an interdisciplinary approach that moves beyond purely economic optimisation to include technological, technical and ecological factors. The present work describes applying the multi-criteria Analytical Hierarchy Process (AHP) method to evaluate road section design in an urban environment through differential weighting of various criteria and sub-criteria. The model is tested on a stretch of National Road D8 in the municipality of Podstrana near the city of Split (Croatia), which serves as an important route for commuters and tourists. The proposed AHP model provided reliable results that were robust to sensitivity analysis. This approach involving differential criterion weighting may prove useful for evaluating and selecting appropriate road section designs for this and other contexts.

National road are crucial to the economy and it spurs the economic development potential of the area contained in the province of Bangka Belitung Archipelago. National road lines is the busiest traffic lane linking inter-cities/regencies in Bangka Island requires maximum handling but the ability of the central government in providing funding is very limited. Prioritization of road handling must be done evenly as needed so that the purpose of the existence of these roads remains unfulfilled. The purpose of this study was to determine the priority handling of national road Lines in Bangka Island by the method of Analytical Hierarchy Process (AHP) using 6 (six) criteria. Data results of the questionnaire showed that of 6 (six) criteria taken in this study namely accessibility (19.3%) is the most dominant criteria. Followed mobility (17.6%), the condition of roads (17.1%), current road segment (16.3%), the development of regional (15.9%), and Economic of Gross Regional Domestic Product (13.8%). By entering the 6 (six) criteria to 21 segments, the roads segment that became the priority of road handling is Sungailiat – Boundary of Pangkalpinang followed Tanjung Gudang - Lumut, and the next successive.

Road an important component for a region, as well as for Magetan Regency, its position is located at the end of East Java, making the road infrastructure very useful. For this reason, it is necessary to assess the condition of the pavement and the outer side of the pavement and get results. The assessment model of the national road component condition in Magetan district was developed by adopting a condition index system according to the weight and hierarchy of each road component. The weighting of road components using the Analytical Hierarchy Process (AHP) method through questionnaires resulted in the weight of pavement components 0,80 and for the components outside the pavement of 0.20 with the road shoulder sub component having a weight of 0.37; drainage channel / edge 0.33; edge slopes 0.15; sidewalks of 0.09 and 0.06 and pavement values using the PCI method, where the results of road performance when observed from pavement or out of pavement spawn periodic maintenance.

Abstract More than 1,24 million people die each year on the worlds roads and between 20 to 50 million suffer from nonfatal injuries. The UN Road Safety Collaboration Meetings under the leadership of WHO developed the Programme for the Decade of Actions for road safety taking nations into the responsibility of improving their accident figures by the five pillars of a national Road Safety Policy, safer Roads, safer Vehicles, safer Road Users and Post Crash Care. It is this Safe System Approach that takes into consideration the land use, infrastructure and transport planning, road user’s abilities and limitations and the close cooperation of all governmental and none governmental stakeholders involved. Following the European Transport Safety Council's (ETSC) 8th Road Safety Performance Index Report on Ranking EU Progress on Road Safety; June 2014 Romania has made progress during the last 10 year but had still the highest fatality rate of 93 fatalities per 1 million inhabitants in Europe. [1] The contribution will present the main activities of the fife pillars with a focus on PIARC's Road Infrastructure Management tools to improve safety and function of the road infrastructure based on the experiences with the land use problems in Asian, African and European countries. A GPS based accident data system will help researchers and practitioners to improve their countries road safety. The report will show the important steps for safer roads which had been developed in Romania and how actions of short and long term measures on all five pillars have reduced the number of traffic victims remarkable in Eastern Germany after reunification and in addition how the hierarchy of motorways, 2+1 express roads, the rural roads and traffic calming in built up areas, have improved the economic development of cities and villages in a safe way.

Full textAbstract:
To achieve sustainable development in the road sector, the use of Electric Vehicles (EVs) appears as a positive response to transport emissions. Among the available technologies, dynamic charging seems to overcome the main weakness points of EVs, even if it requires that traditional roads (t-roads) be equipped with a system providing electricity for EVs. Thus, so-called electrified roads (e-roads) must be implemented into the urban road networks. Since it is not possible to electrify all roads simultaneously, and also to consider the demand needs of citizens, a selection criterion is essential. This research describes and develops a simple, self-explanatory, repeatable, and adaptable selection criterion aimed at helping city managers in prioritizing the roads of an urban network to be upgraded from t-road to e-road status. This method belongs to the so-called Multicriteria Spatial Decision Support Systems (MC-SDSS)—processes useful for solving spatial problems through the integration of multicriteria analysis (Fuzzy Analytic Hierarchy Process, F-AHP) with a geo-referenced data management and analysis tool (GIS). The developed algorithm is based on several criteria related to the infrastructure/transport, social and environmental areas. The result of the implemented method is a Feasibility Index (FI), able to prioritize the roads most eligible to be upgraded as e-roads, as also verified by its application on the urban area of Milan (Italy).

Full textAbstract:
Road management in both Australasia and America has historically focused on facilitating vehicle movement and reducing congestion. More recently, however, there has been a shift to acknowledge the wider role that roads play in society. Road safety, equity impacts, considerations of “place” and the needs of different road users (including transit, pedestrians, and cyclists) are all gaining prominence. Two relatively new approaches to road design and management—Complete Streets in the United States and SmartRoads network operations planning in Australia—embody the spirit of this change. This paper summarizes the development of the Complete Streets movement in America and introduces the SmartRoads management framework, which was developed in the state of Victoria, Australia. In the SmartRoads process, roads within a network are classified in a multimodal Road User Hierarchy, network issues are identified using multimodal level of service measures, and possible operational or design solutions are compared using decision-making Network Fit Assessment software. We compare the scope, emphasis, and approach of the two frameworks; although they were developed at around the same time, the two approaches differ in significant ways. Yet the two approaches can learn from each other in order to significantly improve the management and design of roads in both Australia and the United States.

Abstract The Department of Rural Roads (DRR) is one of the highway authorities in Thailand responsible for over 48 000 kilometres of rural roads and highway networks. One of its responsibilities is to provide better road safety management. In road safety procedures, black spots are usually identified by observing the frequency of accidents at a particular road section. This research aims to develop a model that includes levels of accident severity in the black spot identification process. The classification of severity levels includes fatalities, serious injuries, minor injuries, and damaged property only. The Analytic Hierarchy Process (AHP) is employed to derive the weight of each severity level. The identification model is developed using Equivalent Accident Number (EAN) and Upper Control Limit (UCL). The data applied in the model are obtained from the road accident investigation of DRR. Five roads — Nakhon Ratchasima 3052, Chonburi 1032, Nonthaburi 3021, Samutprakarn 2001 and Chiangmai 3029 — have been selected based on the top frequency accident recorded in the last three years. Based on the results of black spots identified in the study, most accidents occurred from frontal and rear-ended impacts due to exceeded speed limits. The article discusses recommendations.

Efficiently determining Shortest Paths on Road Maps has been a heavily engineered function for many routing apps like Google Maps & Yandex Maps for years now. Dutch computer scientist, Edsger W. Dijkstra set the stepping stone by formulating the now famous, Dijkstra’s algorithm for shortest paths. Later it was improved upon by newer algorithms like A*. We introduce a way to implement modern algorithms such as Contraction Hierarchy, Highway Hierarchy and PHAST Algorithm to find optimal shortest paths in real life scenario road maps. It bases heavily on constructing a virtual “highway” which the shortest path should pass through theoretically as they are heavily traversed in real life generally. It considers parameters such as Road Distance between nodes(Edge Weight), Importance Factor during Contraction Hierarchy Phase, Cartesian Distance From Target, External Real Time Factors like Weather and Traffic. We determine a Heuristic Function using the above parameters and then use that to run a Bi-Directional PHAST based A* from both the source and the target node and then determine the shortest path once a common highway exists in both directional search’s settled vector or a fallback stage is reached.

The article analyzes the transformation processes in the transport system of the Russian Empire as a result of Catherine II’s legislative activity. The empress considered roads not only as means of transportation but also as means of communication (including information communication) linking the whole state. The new road system was to reflect the hierarchy of state power location: capitals – principal towns of provinces – principal towns of districts – gentry estates and rural settlements. Of particular interest are technical innovations in road construction, river channels, bridges and other structures that were especially developed during that period. Some of them were so idealized that they finally remained unrealized.

The importance of road management for the economy and the state as a whole is determined. Developed transport infrastructure and highways are the key to a developed society and the efficient functioning of the economy of any state. According to the latest estimates of the Ministry of Infrastructure, the technical and operational condition of roads meets modern requirements for strength and equality by only 39.2% and 51.1%, respectively, due to the crisis in budget funding, insufficient maintenance of infrastructure, backwardness of technologies in the field of construction, which in turn causes economic and environmental losses in other sectors of the national economy. The main problems that damage the development of the road industry include: non-compliance of road coverage with European standards and traffic intensity, road wear, reduced road safety, poor quality of road repairs, poor control and others. The article examines the state, trends and prospects of road development in Ukraine. The main participants and the hierarchy of road users and the functions they perform are described. The structure of state and local roads of Ukraine is analyzed.

Full textAbstract:
Dust, sediment, and stone chips often block the rainwater-infiltration paths of permeable pavements, which, in conjunction with vehicle load, reduces drainage capacity. To restore this capacity, a reasonable maintenance time and suitable maintenance measures must be determined. Therefore, we investigated the void attenuation and decline in drainage capacity of permeable asphalt pavements under the combined action of dust blockage and vehicle load. First, the water seepage coefficient decay and the decay rate under blocking and compaction were determined via clogging and compaction experiments. Second, experimental data were incorporated into an entropy–analytic hierarchy process analysis model, with the gross domestic product ratio, wind scale, and maximum five-year rainfall for the area. Finally, three test roads were studied as the weight to rank the maintenance urgency and predict the maintenance timing for each road under different rainfall conditions. The results demonstrate that the drainage capacity of permeable pavements obeys the parabolic exponential attenuation law. From the findings regarding road water storage capacity, the latest pavement maintenance time at different rainfall levels were obtained. This predicted maintenance time enables better decisions than regular time on code, which is the effect of drainage caused by multiple factors.

Category1 defects such as potholes significantly accelerate structural deterioration and pose imminent hazards on trunk road networks. Frequent occurrences of category1 defects have increased service disruptions on trunk road networks. Road maintenance agencies are now required to effectively prioritize trunk road network category1 defects maintenance works. However, existing road maintenance prioritization methods such as value engineering and traditional expert judgment methods have limitations. Value engineering is resource and time intensive thus best suited for project level prioritization and traditional expert judgments are subjective and lack audit trails. In an attempt to address the limitations of above methods, this study presents a Reliability Centered Maintenance and Analytical Hierarchy Process based hybrid model for trunk road network maintenance prioritization. The proposed hybrid model is used to establish failure diagnostic and Multi-criteria Decision Making respectively. As a case study, the hybrid model is implemented on a trunk road network in the United Kingdom. Relevant category1 defect failure information linked to trunk road network subassets are extracted from databases and relevant information elicited from maintenance experts. The criticality analysis results presented show the risk priority numbers of category1 defect related failures and cost effective preventative maintenance tasks are proposed. The Analytical Hierarchy Process results are used to address the complex prioritization process. The proposed hybrid model facilitates a systematic prioritization of a large number of trunk road network category1 defect failure maintenance activities consistently.

It is attempted to identify and prioritize the accident prone points (black spots) in “Iraanshahr-Sarbaaz-Chabahar” road located in Baluchistan, Iran, without no use of accident data but rather using Analytic Hierarchy Process (AHP), which is the enhanced procedure of road safety audit technique. First, by surveying the whole route, all factors that could influence accidents in this road were specified; then the route was divided into eight sections; this division was performed based on the uniformity and homogeny of each section in terms of geometric design and regional conditions. In each section, potentially hazardous locations were identified and some questionnaires were prepared, which were filled by 5 road traffic experts familiar with the route; then the collected data were analyzed by Analytical Hierarchy Process (AHP) using Expert Choice Software and the black spots were identified and prioritized. Finally, these black spots were compared with the black spots that had been obtained by traffic police based on accident data.

Purpose – The purpose of this paper is to investigate the use of the impact hierarchy and the optimization model to determine the optimal intervention strategy for a road link composed of multiple objects. The paper focusses on the results of a case study of intervention project on A20 road link in Rotterdam, the Netherlands. Design/methodology/approach – The study was a case study research. It describes briefly the impact hierarchy and its link to the optimization model, and then focussed on analyzing the results obtained from running the model. In order to understand the influence of various factors affecting the results of optimization, sensitivity analysis was performed. Findings – The proposed hierarchy is suitable to be used to support the determination of optimal intervention strategies (OISs) for public road. From the case study, it was also realized that optimal intervention strategy can be changed due to not only intervention costs incurred by the owner, but also due to the setup of traffic configuration during the execution of interventions since the impacts incurred to users, directly affected public, and indirectly affected public are significantly different from one traffic configuration to the others. The optimal intervention strategy also depends greatly on the factors of deterioration during the operation of the infrastructure objects. Research limitations/implications – In the impact hierarchy, some impact factors are difficult to be quantified, e.g., the long-term economic impacts on the region where having intervention projects. The use of only exponential function for impacts could be oversimplified the actual behavior of the impacts. Other functional form should be investigated to be used within the framework of the optimization model. Practical implications – The proposed hierarchy and the optimization model could be used in practical situation for determination of OISs for multiple objects within a road link. Originality/value – This paper contributes to the body of knowledge of stakeholder analysis in the field of infrastructure asset management. It also gives a guideline and tool for infrastructure administrators to select the OISs for their infrastructure network.

With the increasing population of cities, expanding roads as one of the essential urban infrastructures is a necessary task; therefore, adverse effects such as increased fuel consumption, pollution, noise, and road accidents are inevitable. One of the most efficient ways to mitigate congestion-related adverse effects is to introduce effective intelligent transportation systems (ITS), using advanced technologies and mobile communication protocols to make roads smarter and reduce negative impacts such as improvement in fuel consumption and pollution, and reduction of road accidents, which leads to improving quality of life. Smart roads might play a growing role in the improved safety of road transportation networks. This study aims to evaluate and rank the potential smartification measures for the road network in Calabria, in southern Italy, with sustainable development goals. For this purpose, some potential smartification measures were selected. Experts in the field were consulted using an advanced procedure: four criteria were considered for evaluating these smartification measures. The Integrated fuzzy decision support system (FDSS), namely the fuzzy Delphi analytic hierarchy process (FDAHP) with the fuzzy technique for order performance by similarity to ideal solution (FTOPSIS) were used for evaluating and ranking the potential smartification measures. The results demonstrated that the repetition of signals in the vehicle has the highest rank, and photovoltaic systems spread along the road axis has the lowest rank to use as smartification measures in the roads of the case study.

The provincial roads maintenance and repair are often constrained by limited budgets, so that the road management priority is generally determined by policy factors, which often cause roads treatment disparity. The purpose of this study was to determine the criteria and sub-criteria, the weights of criteria and sub-criteria, as well as develop a mathematical equation in order to determine to roads handling priority in the area of Purwakarta, West Java. The Delphi and Cut Off Point methods were applied to determine the criteria, which result in three criteria selected i.e. road condition, traffic volume and economic factors respectively. Afterward, the Analytical Hierarchy Process was used to determine the weighting factors for the criteria and sub-criteria. The results for the criteria weights were as follows: the roads conditions had a weighting factor of 67.7%, the traffic volume of 18.3% and the economy of 13.0%. Based on the criteria and sub-criteria weight, a mathematical equation was developed to define the handling priority of roads in Purwakarta.

<p><em>As one of the busiest toll roads in Indonesia, Jagorawi is exposed to various operational risks. The purposes of this research are to analyze operational risks of Jagorawi toll road and to determine the effectiverisk reduction strategies. Cause and effect diagrams are employed to identify and classify these risks. Then risk priorities are quantified by applying Failure Mode Effect Analysis (FMEA). Finally, in order to determine prioritized strategies, Analytical Hierarchy Process is applied. The results indicate that the main risk is the traffic risk. The most prioritized risk reduction strategies are educating both the toll road users and surrounding inhabitants. This is then needs to be followed by developing the instrastructure, investing human resource quality, automating gate, and improving the service and safety.</em></p><em>Keywords : AHP, FMEA, cause-effect, operational risk, toll road</em>

More than two-thirds of road fatalities in the Republic of Korea (hereafter Korea) occur on roads managed by local governments. There is also a big difference in road traffic death rates between local governments. This study aims to develop indicators to evaluate the current status of road safety management systems (RSMS) of local governments, which can result in different road safety performance. The indicators for RSMS will be categorized into: institutional management, intervention, intermediate outcome, and final outcome. A comparison of those indicators will help local governments to identify the pros and cons of their RSMSs. It will also help to benchmark good practices of other local governments and eventually contribute to reducing the gap of road safety outcomes between local governments. Indicators have been developed for both quantitative and qualitative aspects. The former includes road mortality rates for various road user types and budgets for road safety, and the latter includes the existence of a road safety team and the level of cooperation between relevant organizations. The overall road safety score is calculated based on the weighted sum of the selected indicator scores. The weights are derived through the analytic hierarchy process (AHP). A comparison of developed indicators between local governments shows many local governments in Korea need to set up a responsible organization for road safety. This comparison will also provide useful information on how the central government can help local governments with low scores.

Abstract The main objective of this study is to rank the chief parameters and their important features which lead to rural roads accidents in Iran. To conduct this, an item as Risk Index is defined as the risk of a parameter and feature causing road accidents. Of all detected parameters, only five parameters and their features were chosen. Then Analytic Hierarchy Process (AHP) was applied to find the scores of Risk Indexes of each parameter and feature to rank them with regard to the two main criteria. These criteria were “Effect on Accidents Number” and “Effect on Accident Severity”. The data of this research was collected from two forms of questionnaires. Each of the 622 participants of this research filled both forms of the questionnaires. The results show that considering only Risk Index of main parameters in rural roads led to a big misunderstanding about detecting traffic accident causes. A comparison between obtained scores for both Risk Indexes of parameters and features clarifies that paying more attention to road features rather than road parameters can bring about detecting hazardous locations more accurately to assign limited budget to vulnerable locations in rural roads and decrease the rate of traffic accidents.

Landslides are a very dangerous threat to the roads. Good management is required to prevent the problems occurring from extensive possible landslides. This is because the number of potential landslide points on the National roads are numerous. Maintenance and prevention are crucial to keep these disasters from occurring. Therefore these need to be a priority. The locations in question are: The National Road in the Provence of North Sumatra, the area of Satker PJN Ill (Satuan Kerja Pelaksanaan Jalan Nasional III) and The Satker PJN IV (Satuan Kerja Pelaksanaan Jalan Nasional IV). There are 26 roads in the Satker PJN III and IV areas with 34 that have occurred. The method that is used in this study is the AHP (Analytical Hierarchy Process). Method using two stages: The first stage is to analyze the level of landslide hazard on the road. The second stage is to determine the priority level for the handling of each landslide point for each section of the road. The parameters used determining the level of landslide hazard are: Soil, slope, landcover, rainfall, subgrade and drainage conditions, at the same time as using the landslide hazard perimeters, landslide dimensions, slope engineering and every day traffic
