Abstract

Traffic accident on expressway is one of main reasons of traffic congestion on the road section and the road network. In order to accurately estimate expressway capacity under traffic accident and upstream direct traffic diversion, a parking model of traffic accident section is presented with VISSIM parking tool, and sensitivity of simulation parameters is analyzed with single-factor displacement method. Then choosing travel time as the correction index of the simulation model parameters, a VISSIM simulation parameter correction program based on genetic algorithm is designed. Finally, a rear-end accident on four-lane expressway is used as case study, the results show that the relative error rate between simulation and actual investigation is 3.04%, which validates that the correction model of simulation parameter is reasonable.
