Advanced OR and AI Methods in Transportation PATH SEARCHING AND FILTERING FOR NETWORK SIMULATION TOOLS AIMED AT ROBUSTNESS ANALYSIS

Traffic simulation models dealing with road networks are already available for several years. Most of them include procedures to distribute traffic over alternative routes between an origin and destination. However, most of these tools are not capable to include ADAS and route guidance systems realistically. In addition, the interest in the design of reliable and robust networks is growing, while a tool to analyze and quantify these properties is still missing. One important element in such a tool would be the realistic distribution of traffic over logical paths, and the availability of dissimilar alternative paths in case of emergencies. An overview and a new approach are presented in this paper.
