The popularity of location-based services and the need to perform real-time processing on them has led to an interest in queries on road networks, such as finding shortest paths and finding nearest neighbors. The challenge here is that the efficient execution of operations usually involves the computation of distance along a spatial network instead of “as the crow flies,” which is not simple. T...

Road network management is an important task for the economic and social growth. In the context of an Indian city, efficient road network management is required to overcome the problem of traffic congestions and road accidents. Computer traffic simulation is a better way to analysis the road network. In this study a maiden attempt for a systematic empirical traffic simulation study is performed...

This work provides a practical method for the development of rural road networks in rural areas of developing countries. The proposed methodology enables to determine obligatory points in the rural road network maximizing the number of settlements that have access to basic services within a given maximum distance. The proposed methodology is simple and practical, hence, highly applicable to rea...

abstract: gridlock is an extreme traffic state where vehicle cannot move at all. this research studies the development of gridlock by theoretical and numerical analysis. it is shown that the development of gridlock can be divided into several stages. the core of the development is the evolution of congestion loop. a congestion loop is comprised of a number of consecutively connected spillover l...

an urban map, the procedure composes the road-network by searching the roads from each intersection. Next, it In this paper, we propose an experimental method to modifies the road-network by interpreting the original urrecognize roads from an urban map on the basis of the ban map and the network simultaneously with heuristic road-network. The road-network is a conceptual graph knowledges about ...
