直达轨道交通的拥挤瓶颈模型

首先,运用瓶颈模型的思想对直达轨道交通拥挤进行分析。分析包括两个方面,一是考虑轨道交通输送能力的限制,提出了拥挤风险费用的概念,解决了轨道交通出行费用不等的问题;二是根据用户平衡原则,通过寻找出行者选择不同出发时刻的费用平衡点,得到平衡情况下的出行费用;其次,对拥挤风险费用与出发率等特征进行分析,得出平衡条件下的出行规律,并与经典瓶颈模型进行比较。最后,给出一个算例。

A bottleneck model for the congestion of through rail transit

This paper analyzes and extends the bottleneck model to rail transit congestion. The analysis is in two aspects. On the one hand, this paper considers the restriction of rail transit capacity and putting forward congestion risk cost to tackle the problem of unequal trip cost of rail transit users. On the other hand, through studying the costs incurred on commuters, this paper investigates the user equilibrium of rail transit. Secondly, this paper analyzes the characteristic of congestion risk cost and departure rate. The law of rail fransit users under equilibrium conditions has been obtained and compared with the classical bottleneck model. Finally, this paper puts forward a simple case to explain the model.
