摘　　要：收取交通拥挤费作为交通需求管理的一种有效措施在许多国家和地区开始提倡。本文提出了根据多路径选择的交通分配双层规划模型结果,建立的交通拥挤定价模型。针对双层规划模型,采用了Kuhn-Tucker原理将双层规划模型转化为单层规划问题求解。算例分析不同拥挤费对交通量分配的影响,结果表明模型可以兼顾社会总成本与个人成本的利益,合理确定拥挤费用。Traffic congestion pricing has been adopted as an effective measure tbr traffic demand management m many countries and regions. This paper mainly focuses on the study of traffic congestion pricing model based on the results of multi-path choosing traffic assignment bi-level programming. The bi-level programming can be transferred into the single-layer model using Kuhn-Tucker theory. Example analyzes the impact of different con- gestion prices on traffic assignment, and results shows that model can take both social costs and personal interests into account to determine the price of congestion reasonably.
