摘要
在假设乘客对拥挤敏感程度具有异质性的基础上分析公交乘车的成本构成,并利用Wardrop用户分配第一准则对多起点单讫点的公交线路建立了基本均衡模型,通过数学推导,证明了在该假设下早高峰的存在性,并探索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.
This paper analyzes the equilibrium properties of the morning peak-period commuting profiles in a many-to-one transit system with in-vehicle crowding effect and schedule delay cost. Passengers are assumed to be heterogeneous, which means different passengers have different crowding effect functions. The passengers 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 the existence of the morning peak-period. In addition, we find how heterogeneous passengers choose travel time and distribution characteristics between heterogeneous passengers under the equilibrium condition.
