摘要
为描述交通事故影响下路径走行时间与用户择路概率的相互作用及其演变规律,建立了基于路段传输模型和LOGIT选择模型的拟动态模型,给出了事故影响下路网各时段行程时间和交通流密度的计算方法,分析了事故影响下路段的排队扩散及消散过程.结果表明:事故持续期到排队完全消散期内,路径走行时间和路径选择概率呈现此消彼长并持续震荡的状态;事故持续期和事故清除后,事故路段上的排队位置发生转移.
In order to reveal the interaction and its evolution rule between route travel time and route choice proba- bility 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.
