出行者有限理性条件下混合策略网络均衡模型

Network Equilibrium Model with Mixed Strategies under Bounded Rationality

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。

Taken traveler＇s trip under the condition of continuous random distributed road network travel time as research object,combined the background of gradually popular traffic information system in China,the travelers were divided into different types according to the travel strategies.Also,by introducing the bounded rationality into path utility function to build traveler＇s path perception utility function on the basis of cumulative prospect theory.Then,a network equilibrium model for multiple users was built combining the Wardrop principle and the variational inequality.The case analysis proved the model＇s scientificity for describing the traveler＇s route choice behavior and predicting road network traffic flow distribution under the unclear travel time.
