公交挤车是许多公交线路上常见的现象，其中一辆车的初始延误可能会扰乱整个公交计划，因为这会导致后续公交在站点停留时间的差异。本文研究了当车站有多辆公共汽车服务时的乘客行为，重点研究他们的选择和从排队等候的公共汽车换乘的可能行为。引入参数γ来表示同时上车的两辆公共汽车中乘坐前排公共汽车的乘客百分比。在允许或不允许超车的情况下，这也会影响乘客的行为。然后实现一组离散状态方程，以获得在其中一辆公共汽车发生外生延迟后公共汽车的出发时间。引入评价指标来衡量不同γ水平下走廊公交服务的绩效。我们表明，保持乘坐前排公共汽车的乘客比例较低是有利的。此外，超车是相对较高的前车偏好的有利对策。
ABSTRACT Bus bunching is a well-known phenomenon on many bus routes where an initial delay to one service can disturb the whole schedule due to resulting differences in dwell times of subsequent buses at stops. This paper deals with the passenger behaviour when there is more than one bus serving the stop, focusing on their choices and possible switching actions from the queue of the bus they are waiting to board. A parameter γ is introduced to denote the percentage of passengers boarding the front bus of two buses boarding at the same time. Cases when overtaking is allowed or not are distinguished as this will also influence the passenger behaviour. A set of discrete state equations is then implemented to obtain the departure times of the buses following the occurrence of an exogenous delay to one of the buses. Evaluation indices are introduced to measure the performance of the bus service along a corridor under different γ levels. We show that it is advantageous to keep the percentage of passengers boarding the front bus low. Beside, overtaking is a favourable counter-measure against comparatively high front-bus preference.
