Dynamic Traffic Simulation for Accessing Road Network Reliability under Large-Scale Events: System Development and Case Studies

A dynamic traffic simulation system for accessing the road network reliability under large-scale events was developed,by using the dynamic traffic simulation model INTEGRATION and road network reliability evaluation methodologies. First,the functional modules of the system were described,which included road network module,traffic demand generation module,traffic simulation module,and road network reliability evaluation module. Then,the road network reliability evaluation systems and algorithms were developed. Therefore,it provided a set of effective analysis tool for evaluating the road network reliability under large-scale events. Finally,a real vocal concert in Beijing Capital Gym was selected as the case study.
