考虑停车位置和步行成本的双起点单讫点通勤均衡分析

考虑来自两处不同居住地的通勤者, 经由两条完全不重叠的含有瓶颈的道路,到达同一个工作地上班的问题, 引入两组通勤者对于停车位的竞争,在瓶颈模型的基础上, 构造停车位置函数,建立了考虑步行成本的出发时间选择模型.根据两组通勤者通勤高峰开始及结束的早晚关系, 将均衡状态分为 4 种情形, 并进一步考虑通勤者准点到达时刻, 分为 14 种子情形,推导得出了通勤者的出发和到达曲线. 最后,通过算例分析了两组通勤者时间价值相同且两条道路的瓶颈通行能力相同的条件下,均衡态随步行速度、出行人数变化的情况.

An equilibrium analysis of commuting considering location of parking slot and walking cost in a two-to-one network

Commuters from two different residence places drive to the same working place through two completely non-overlapping highways with bottlenecks and share a parking space. Based on the classical bottleneck model, we introduced competition for parking spaces between the two groups of commuters, constructed a function about location of parking slot and established the departure time choice model considering walking cost. Based on the start time and end time of the rush hour of the two groups, the equilibrium state can be classified into four situations. Considering the time of on time arrival, the four situations can be further classified into 14 sub-situations. We have derived the departure pattern and arrival pattern of the commuters in these sub-situations. Finally, considering the scenario that two groups of commuters have the same value of time and the bottleneck capacities on the two highways are also the same, numerical examples have been presented to show how the equilibrium state changes with walking speed and commuter numbers.
