Abstract:

In order to reveal the interaction and its evolution rule between route travel time and route choice probability in traffic accidents,a quasi-dynamic model is established based on the link transmission model and the LOGIT model,and the methods to calculate the travel time and the traffic flow density are respectively presented. Then,the corresponding queue dispersing and dissipating courses are analyzed. The results indicate that the route travel time and the route choice probability rise and subside alternately and remain in a concussed condition during the accident and in the queue dispersing process,and that the queue spot transfers in the accident duration and in the clearing period.

Key words: traffic accident, link transmission model, route travel time, route choice probability, traffic flow density
