基于网络均衡的运输通道客流分配模型

Trip Assignment Model for Transportation Corridor Based on Network Equilibrium

根据各运输方式的经济技术特征,构建了运输通道的时空运营网络来描述各运输方式的竞争性。认为旅客的时间价值(VOT)服从某种分布,旅客的广义出行费用取决于票价和时间两个参数。运用城市交通分配网络均衡思想,提出基于网络的区域运输通道多交通模式客流分配模型,建立了用户最优和系统最优两个目标函数,并给出了模型的求解方法。用一数值示例验证了模型的有效性。

Based on operational characteristics of each transportation mode, a time-space operational network of a regional transportation corridor, which can reflect mode competition, is constructed. Let the probability density function of the distribution of VOT across the user population be represented by certain distribution, the cost of the system users be composed of time and fare, using the idea of network equilibrium, the trip assignment model for transportation corridor is developed. Two objective functions of UE and SO are formulated, and the solving algorithm is presented. With a practical example, the model is tested.
