摘　　要：分析了交通方式服务可靠性的特点和计算方法,并将其引入到效用函数中,提出了考虑方式服务可靠性的效用函数模型,给出了不同交通方式间的均衡配流模型.利用灵敏度法分析了不同方式出行时间可靠度改善对客流的影响关系,给出了具体的关系模型.通过一实例表明该模型与算法是有效的.When people decide which mode to be selected before a trip, not only fare and time but also the service reliability of modes is regarded as an important factor. Firstly, the meaning and expression of service reliability are interpreted fully. Under this condition, the utility function model is presented which consider the service reliability of different modes. And an equilibrium model for different traffic modes is proposed. Then the relationship between reliability of traffic modes and passenger flow is analyzed, and a material model is put forward. Finally an illustrative example is given to show the relationship between service reliability of traffic mode and passenger flow volume.
