将道路交通网络出行时间连续随机分布条件下的出行用户交通出行作为研究对象,结合我国交通信息系统逐步普及的背景,按其所采用出行策略的不同划分出行用户,将出行者有限理性的特点引入到出行者路径效用函数当中,以累积前景理论为基础,建立出行者的路径感知效用函数。结合W ardrop原理和变分不等式思想建立多类型用户的网络均衡模型,通过实例分析,证明了文中模型在描述出行时间不明确条件下出行者的路径选择行为和预测道路网中交通流量的分布形态方面的科学性。
Based on the background of gradual popularization of traffic information system in our country, the traveling users who travel under the conditions of continuous and random distribution of the travel time of the road network are taken as the research object. Based on the gradual popularization background of the traffic information system in our country, To the traveler’s path utility function, based on the accumulated foreground theory, the path-aware utility function of the traveler is established. Based on W ardrop principle and variational inequality, a network equilibrium model of multi-type users is established. By the example analysis, it is proved that the model of the route selection behavior of the traveler and the distribution of the traffic flow in the road network under the conditions of describing the travel time are not clear Scientific aspects.
