摘　　要：基于流量依赖的突显理论,考虑出行时间和出行成本的双重影响,提出了双属性突显出行效用模型,并采用了一种构造性的方法证明并界定了均衡存在性和唯一性成立的充分条件,通过数值检验验证了本文理论的正确性。研究结果表明,均衡是否存在以及所处位置与出行者对于突显的敏感度和道路收费设计密切相关,通过对相关变量的控制可以影响出行者的出行方式,该研究结果对于未来交通网络及拥堵收费的最优设计提供了新的依据与思路。Based on the flow-dependent salience theory,the dual effects of travel time and travel cost were considered,a bi-attribute salient travel utility model is proposed,and a constructive method is used to prove and define the sufficient conditions for the existence and uniqueness of equilibrium.The correctness of this theory is verified by numerical examination.The research results show that whether the equilibrium exists and where the location is closely related to the traveler’s sensitivity to the salience and the road toll design.Through the control of relevant variables,the traveler’s travel mode can be affected.The research results provide a new basis and idea for the optimal design of traffic network and congestion charging in the future.
