中文摘要
      本文在假设乘客对拥挤敏感程度具有异质性的基础上分析乘客乘车成本的构成,并对双起点单讫点的公交线路,利用 Wardrop用户分配第一准则建立了均衡的基本模型,通过数学推导,证明了在该假设下早高峰的存在性,并证明了均衡条件下不同类型的乘客间的混成特点以及分布特征。算例结果支持了模型的结论。这有助于加深对复杂交通行为的理解,对改进公交规划与管理具有理论指导价值。
英文摘要
      This paper analyzes the equilibrium properties of the morning peak-period commuting profiles on double origins and single destination transit system with in-vehicle crowding effect and schedule delay cost. Commuters are assumed heterogeneous, which means different commuters have different crowding effect function. Commuters always choose their optimal time-of-use decision from home locations to a single destination by trading off the travel time and the crowding cost against the schedule delay cost. In these conditions, a Wardrop equilibrium model is established. We first prove existence of the morning peak-period. In addition, we find how heterogeneous Commuters choose travel time and distribution characteristics between different Commuters types under equilibrium condition.
