摘　　要：通过分析交通信息对出行者路径选择行为的影响,构建了一个同时考虑惯性出行者和非惯性出行者路径选择行为的混合用户均衡模型.随后,提出了求解混合用户模型的算法,通过算例对模型和算法的合理性进行验证,并探讨当出行者路径选择存在惯性行为时,交通信息是否能够缓解交通拥堵.研究发现交通信息虽然可以影响出行者的路径选择行为,但是可能会增加整个系统的总出行时间.而合适的信息渗透率有助于显著地减少整个系统的总出行时间,使得系统趋向于最优化.By analyzing the impact of traffic information on travelers’ route choice behaviors,this paper developed a mixed user equilibrium model.And in the mixed user equilibrium model,we considered two types of travelers:Inertial choice travelers and non-inertial choice travelers.Then,numerical examples were provided to illustrate the application of the proposed mixed user equilibrium model,and explored whether traffic information would help to relieve congestion when the travelers’ route choices are inertial.The results showed that the traffic guidance information can influence travelers’ route choice inertial behavior,but can also lead to increase the system’s total travel time.Moreover,an appropriate permeability of traffic information can help to reduce the system’s total travel time and make the system tend to optimize.Such an understanding has important implications on traffic information compliance.
