公交车辆在中途站点的排队论分析

公交站台停靠区的排队问题决定了公交车辆的通行能力。把公交中途站台与公交车辆模拟成一个单服务系统、公车到达率 ，两服务率 、 的负指数分布的排队M/M/1/N系统。根据排队论理论，实测计算了北京中关村海淀黄庄、人民大学站点公交车辆排队队长，站内逗留时间等参数。结论为：城市主干道关键站台改造为主、副双公交站台制式以及调整公交线路布设，优化各线路发车频率是花费成本低，畅通成效大的解决站点塞车排队的方法。

The Procession Theory Analysis of Buses Midway Site

The queuing problem in bus stops determines the vehicle capacity. We simulate a list service system the public transportation midway platform and the public transport，public transportation vehicle to arrive a rate , two service rates 、 , of the negative index number distribute of in procession M/M/1/N system. According to queuing theory, we measured the parameters such as buses queue and waiting time in HaiDianHuangZhuang station and People’s University station. The conclusion is: In order to solve the queuing problem and traffic jam in bus stations with low cost, we should transform the key stations for urban trunk road into primary and secondary double standard bus stations, adjust bus lines laid, and optimize the bus headways.
