ABSTRACT
ABSTRACT: Highways are suffered from the recurrent accidents. Although the locations of these accidents are known, their impact to the traffic flow for imposing the control strategies is still a challenging issue. So, recent investigations revealed that there is a substantial need for the development of a micro-simulation designed for traffic interaction assessments. Traffic interactions are complicated relations among drivers, vehicles and the road or the environment. The large and different types of data, analyses and criteria involved in traffic situations as well as their dependency to space and time are important motivations of using spatio-temporal geospatial information system (GIS) in this kind of problems. In this context, this paper considers a spatiotemporal GIS-based multi agent traffic micro-simulation for Shahid Chamran highway, one of the most important roads in Esfahan traffic network, in order to investigate traffic interactions caused by some accidents and identify the most important accident locations. Tests of the proposed method are conducted and the results show the efficiency of the algorithm and support our hypotheses.
