基于行人仿真的中运量公交站台的规模分析与设计

Scale Analysis and Design of Medium-Capacity Bus Stops Based on Pedestrian Simulation

摘要:

公交站台是客运系统中的重要一环，合理设计公交站台能够有效显著提升乘客出行体验和出行效率。以上海市71路公交西延伸工程为例，基于行人运动规律，为中运量公交站台的设计和服务水平评价提供支撑。首先，通过计算中运量公交泊位数得出站台的最小长度。然后，基于行人运动基本图和速度优化公式建模仿真，分析乘客在不同场景和状态下的运动速度、密度和流率情况，得出通道宽度等场景的较优解；最后，对站台服务水平进行评价，得出不同服务水平下的行人运动速度与流率，并结合71路公交西延伸工程设计进行了验证；行人仿真为中运量公交站台的规模分析提供了一个新的方法，可供类似工程参考。

Abstract:

Bus stops are an important part of the passenger transport system. Rational design of bus stops can effectively and significantly enhance the travel experiences and travel efficiency of the passengers. Taking the Shanghai Bus Route 71 West Extension Project as an example, and based on the movement laws of pedestrians, a support for designing the medium-capacity bus stops and evaluating the level of service (LOS) is provided. Firstly, the minimum length of the bus stops is obtained by calculating the number of parking spaces for medium-capacity buses. Subsequently, based on the basic graph of pedestrian movement and the speed optimization formula, the modeling and simulation are conducted to analyze the movement speed, density and flow rates of the passengers under the diverse scenarios and states for obtaining the better solutions of scenarios such as channel width. Finally, the LOS of the bus stops is evaluated to give the movement speeds and flow rates of the pedestrians under the different levels of service, which are verified with the design of the Shanghai Bus Route 71 West Extension Project. The pedestrian simulation provides a new method for the scale analysis of medium-capacity bus stops and can provide a reference for the similar projects.
