| 摘 要： | 在交通信息系统作用下的路网中,出行者会根据交通信息系统提供的交通状况信息和以往的经验来选择自己的出行路线和出发时间.根据出行者对交通信息的信任和接受程度,文中将出行者分为怀疑保守型、信任乐观型和中庸型3种类型.在获得路径旅行时间信息和已往旅行经验的基础上,推导出新一轮的期望理解路径旅行时间函数,讨论了该函数的特性,建立了一个等价的随时间演进的随机用户均衡模型,并用一算例验证了模型的效率.

| Abstract: | In a road network served by advanced traveler information system(ATIS),commuters will select their routes and departure times through comprehensively utilizing previous knowledge on traffic condition and current information from ATIS.In this paper,we divide all commuters into three types,namely optimism,pessimism and compromise with different attitudes toward ATIS service,and study their travel choice behaviors.We then formulate an expected perceived travel time function that will be used as personal knowle... |
