To have an effective development among the isolated, remote areas, rural transportation is recognized as a key factor. Efficient rural transportation depends largely on a well-knit road network to provide accessibility and mobility in rural areas. This work affords an applied method for the development of rural road networks in rural areas of developing countries. The proposed methodology enables to determine nodal points in the rural road network based on the facility index of the settlements. The rural road network is generated by connecting the nodal points by minimum travel time path in Geographical Information System (GIS). Spatial analysis is carried out in the study area to identify the Desirable Coverage Distance of the Facility(DCDF). The Village Facility Index (VFI) is calculated by considering the desirable coverage distance. The suggested methodology is simple and practical, hence, highly applicable to real-world scenarios, as demonstrated in the definition of the road network for the rural areas.

Abstract A sustainable transportation system is possible only through an efficient evaluation of transportation network performance. The efficiency of the transport network structure is analyzed in terms of its connectivity, accessibility, network development, and spatial pattern. This study primarily aims to propose a methodology for modeling the accessibility based on the structural parameters of the urban road network. Accessibility depends on the arrangement of the urban road network structure. The influence of the structural parameters on the accessibility is modeled using Multiple Linear Regression (MLR) analysis. The study attempts to introduce two methods of Artificial Intelligence (AI) namely Artificial Neural Networks (ANN) and Adaptive network-based neuro-fuzzy inference system (ANFIS) in modeling the urban road network accessibility. The study also focuses on comparing the results obtained from MLR, ANN and ANFIS modeling techniques in predicting the accessibility. The results of the study present that the structural parameters of the road network have a considerable impact on accessibility. ANFIS method has shown the best performance in modeling the road network accessibility with a MAPE value of 0.287%. The present study adopted Geographical Information Systems (GIS) to quantify, extract and analyze different features of the urban transportation network structure. The combination of GIS, ANN, and ANFIS help in improved decision-making. The results of the study may be used by transportation planning authorities to implement better planning practices in order to improve accessibility.

Over the past few decades, the growth of the urban population has been remarkable. Nowadays, 50% of the population lives in urban areas, and forecasts point that by 2050 this number will reach 70%. Today, 64% of all travel made is within urban environments and the total amount of urban kilometers traveled is expected to triple by 2050. Thus, seeking novel solutions for urban mobility becomes paramount for 21st century society. In this work, we discuss the performance of vehicular networks. We consider the metric Delta Network. The Delta Network characterizes the connectivity of the vehicular network through the percentage of travel time in which vehicles are connected to roadside units. This article reviews the concept of the Delta Network and extends its study through the presentation of a general heuristic based on the definition of scores to identify the areas of the road network that should receive coverage. After defining the general heuristic, we show how small changes in the score computation can generate very distinct (and interesting) patterns of coverage, each one suited to a given scenario. In order to exemplify such behavior, we propose three deployment strategies based on simply changing the computation of scores. We compare the proposed strategies to the intuitive strategy of allocating communication units at the most popular zones of the road network. Experiments show that the strategies derived from the general heuristic provide higher coverage than the intuitive strategy when using the same number of communication devices. Moreover, the resulting pattern of coverage is very interesting, with roadside units deployed a circle pattern around the traffic epicenter.

The road sector in Botswana continues to develop its road network throughout the country at a tremendous rate. When Botswana gained independence in 1966, it had only 10 km (16 mi) of bitumen road. By 1992 the total length of bituminous surfaced road reached 3500 km (2,175 mi) out of a total road network of 18 000 km (11,285 mi). These statistics clearly show that the majority of roads are not yet surfaced; these are low-volume roads that provide access to the rural areas where most of the country’s population is found, though in low density. In spite of the rapid improvement in the quality of the national road network in recent years, much remains to be done. In the early 1970s and early 1980s the rural roads unit was introduced in the Ministry of Works Transport and Communications, which was charged with the responsibility of design and construction of low-volume roads around the country in a bid to integrate the country’s road network. This unit was later disbanded in the 1990s, and all roads are improved through the conventional procurement system using private contractors. For these roads the justification of a surfacing project based on conventional economic return methods does not apply, and worse still, the road improvements have to compete with other amenities for the same limited resources. Three ministries in Botswana are responsible for roads: Ministry of Works Transport and Communications, Ministry of Local Government, and Ministry of Trade, Industry, Wildlife and Tourism. These ministries have different responsibilities for different roads within the country, and earth, sand, and gravel roads are found under the jurisdiction of each of the ministries. The major drawbacks concerning low-volume roads in Botswana are inadequate maintenance, poor road construction materials, and the environmental impacts of the roads. Since the budget and resources are inadequate to keep these roads in good condition, it would be prudent to find technological means that would improve the locally available road construction materials so as to minimize their effects on the environment and vehicle operating costs.

Internal Debt

The aim of this paper is to present the issue of financing the extent and quality of the road network, which is a necessary prerequisite for economic and social development of the Vysočina Region. The paper gives a methodological approach to the calculation of internal debt of the road network in the Vysočina Region, made its own calculation in the alternatives, whereas those alternatives reflect financing by the region through its own resources, as well as an alternative, which includes financing and the involvement of external resources (loans, fund state infrastructure and European sources). The calculation determines the size of internal debt, and therefore the extent of the problem. The definition of internal debt we can express as an annual expenditures which has to follow to the road infrastructure to ensure the sustainable quality of road network. The paper describes a potential process ensuring the increase of efficiency of public financing for the road network. In the contribution there is designed a potencial solution which deal with dividing regional roads into main three categories and in one of the category to introduce the system of road management.

Graph partitioning has many applications. We consider the acceleration of shortest path queries in road networks using Customizable Contraction Hierarchies (CCH). It is based on computing a nested dissection order by recursively dividing the road network into parts. Recently, with FlowCutter and Inertial Flow, two flow-based graph bipartitioning algorithms have been proposed for road networks. While FlowCutter achieves high-quality results and thus fast query times, it is rather slow. Inertial Flow is particularly fast due to the use of geographical information while still achieving decent query times. We combine the techniques of both algorithms to achieve more than six times faster preprocessing times than FlowCutter and even faster queries on the Europe road network. We show that, using 16 cores of a shared-memory machine, this preprocessing needs four minutes.

The PURA (Providing Urban Amenities in Rural Areas) scheme has been designed to induce sustainable growth in underdeveloped areas. The test region is the Nuh Block, Haryana, a region severely lacking the amenities required for an area with a population of 201,816 which is increasing rapidly. The proposed development period of 2005 to 2020 is split into three equal phases to help distribute the expenditure evenly over time. Five ‘nodal’ villages are chosen to act as centres of development for the block. These are linked together through the road network system. Three alternative networks are discussed in terms of the cost-effectiveness of the design.

Purpose The quantity of e-taxi in Bangladesh is increasing day by day, especially in the municipality area. With the increase of this e-taxi quantity, it becomes hard to provide parking space for these consequences the illegal parking on road. This parking consequences traffic congestion on the road and obstructs the free flow of traffic. So, this paper aims to investigate the present scenario of this e-taxi parking problem and provides a solution by finding out a suitable location for an e-taxi station by the analytic hierarchy process (AHP) approach. Design/methodology/approach For the study, both primary and secondary data were collected. Primary data on existing parking points on the road of e-taxi which consequences traffic congestion are collected from the Municipality area. Secondary data on the existing road network of the Pabna Municipality has collected from the MIDP data also from the literature review. For the suitability analysis process for establishing an e-taxi station, six variables were determined. These variables are determined from the previous studies and the expert opinion survey. The six variables are land use of the study area, road network of the study area, proximity to the office area, proximity to the educational facilities, proximity from the market and finally,proximity from the hospital. After the selection of the variables ranking value was determined from the expert opinion. Then using The AHP method final weight value is determined and, finally, with the assist of geographical information system. Findings From the resulting total 4,285 spots were found as optimally suitable spots are found which is almost 21% of the suitable spot. No mostly suitable spots are found from the GIS analysis. The moderately suitable spots were found in the prime number of 14,817 spots, almost 75% of the suitable spot. Likely the most suitable spots no partly suitable spots were found but the number of very few suitable spots was found in the number of 918, 4% of the suitable spot. A total of 20,020 spots was found as suitable for the construction of E-taxi station. Originality/value Finding out a suitable spot for e-taxi stand the traffic congestion can be solved, accident risk can be minimized during loading and unloading of passengers and the municipality authority can find a permanent solution for the traffic congestion problem.

The Village

In the present paper, the serious landslide phenomena that make difficult the residential development of Kanalia village are studied. Kanalia village is located on a slope of the eastern bank of Roustianitis torrent, the main hydrographie axis of the broader area, which is one of the main branches of Sperchios River. The geological structure of the area (sandstones and siltstones of the Pindos zone flysch) as well as the hydro meteorological and climatological conditions favoring the formation of locally very thick weathering mantle and also the development of seasonal aquifers, were at first studied. As it was confirmed, the main causes of landslide phenomena manifestation are related to the above conditions, to the erosional activity of water in the slopes of the hydrographie axes and finally to the human interventions.These phenomena are observed in five (5) main sites with most important the one affected the South - Southwest part of the village covering the area from KanaliaGardiki provincial road until Roustianitis torrent downwards. In that case, the periodic re-activations of the sliding phenomena during the last forty years have caused full destruction and abandonment of this part of the village, since no relevant measures have been taken so far. The remaining sites are restricted in some parts of the village road network, without affecting residential zones.For the protection and development of the residential area of Kanalia village, the following measures were recommended for the improvement of the ground conditions in the slope affected areas: (a) drainage both of the surficial and ground waters in the vulnerable zones, (b) slope supporting works with gabion walls (flexible structures), (c) protection of the stream slopes from erosion and undermining with gabion walls and gully dams, (d) tree plantations, and (e) suitable and appropriate foundation of the new constructions on the stable basement or foundation using specific types, if necessary. It is suggested the application of these measures for the safety of the road network, the good operation of which constitutes a prerequisite for a safe residential development.
