实时定点停靠公交站通行能力研究

摘要

Based on the analysis of vehicles stop process in multi-berth bus station,this paper ana-lyzed the advantages and disadvantages of the three kinds of docking mode;and then brought forward a re-al-time-pointing-parking for the multi-berth bus station,which aims at improving the traffic organization, reducing vehicle delay and increasing the bus capacity in the station.The system consists of platform-real-time-intelligent-guiding,bus-real-time-pointing-parking and passenger-real-time-pointing-queuing.After analyzing bus dwelling feature in the real-time-pointing-parking bus station,the paper explained the defi-nition of the average berth delay,and then gives the probability distribution model to the length of bus team calculation method of the long delay and the corresponding delay of each kind of bus team with dif-ferent length.Finally the paper brought forward calculation method for the station capacity under the sys-tem above:the team-through method.At the end of the paper,the writer collected data of Chengdu bus station,and then calibrated the parameters in the capacity model and analyzed the effect of the real-time-queue-guiding system on improving multi-berth bus station capacity.%按照停靠组织方式的不同，将现有多泊位公交站划分为：独立停车位定点停靠公交站、顺序进出站依次停靠公交站以及交叉进出站自由停靠公交站。以上述3种公交站各自停靠特征的对比分析为基础，以改善公交站内交通组织秩序、减少车辆站内延误、提高公交站通行能力为目标，提出以站台实时智能引导、乘客实时定点排队与车辆实时定点停靠为核心的实时定点停靠公交站。通过分析实时定点停靠公交站内车辆停靠特征，定义了平均泊位延误，进而给出了系统下车队队长概率分布的模型以及不同队长对应的车队延误计算方法，最后提出实时排队诱导系统下多泊位公交站通行能力计算方法：车队通过数法。文章的最后利用成都常规公交站实测数据，标定了实时排队诱导系统下多泊位公交站通行能力计算模型中的参数，分析了实时排队诱导系统在提升多泊位公交站通行能力上的效果。
