大型活动地面公交组织仿真研究

有效的交通组织是成功举办各类大型活动的关键因素之一，而地面公交的组织是大型活动交通组织的一项重要内容。本文运用VISSIM和Legion微观交通仿真软件的功能，以北京奥运会工人体育馆的地面公交组织为案例进行了仿真研究。通过仿真分析，发现了观众到达站台的时间过于集中和公交车辆进出站相互干扰的问题，提出了适当增加观众的步行距离，扩建公交站台的改进措施。通过对改进措施的仿真，结果表明，本文提出的改进措施可以有效的提高公交车辆的运行效率和行人交通的服务水平。

Simulation and Analysis on Ground Public Transportation Organization in Special Events

The effective transportation organization is one of key aspects to hold a successful special event, and the ground public transportation organization is an important content in special event transportation organization. VISSIM and Legion as micro-simulation software are used to analyze the ground public transportation organization of Workers’ Gymnasium in Beijing Olympic Games in this paper. By the method of simulation analysis, the problem in this case study are that the audience arrival to the stop is too concentrated and that the traffic jam is very severe when buses pull in and out of the stop. Some improved methods, such as increasing audience walk distance suitably and adding the stop platform measure, are proposed. Simulation results denote that the proposed methods are valuable in improving the efficiency of the public transportation system and the level of service of pedestrian.
