苏州星湖街公交主干线优化方法研究

Optimization Method for Xinghu Street Bus Trunk Line in Suzhou

在城市轨道交通快速发展的背景下,城市公共交通客流逐步提升,常规公交因线路运送速度、准时性等问题,客流吸引力逐步降低。为提升主要客流通道公交线路运送速度,提升公交出行吸引力,利用轨道交通刷卡数据、常规公交刷卡数据对既有线路客流特征进行分析,制定初步优化方向,利用手机信令数据和互联网开放地图导航路径对沿线职住特征、途经通道人群出行起终点和相连道路专项特征进行分析,对优化方案进行补充。最后,以苏州工业园区星湖街客流通道为例,对相关线路进行优化。优化后主干线176路平均运送速度由21.3 km/h提升至26.0 km/h,单程时间由60 min下降至40 min。

With the rapid development of urban rail transit,the passenger flow of urban public transportation is gradually increasing,but the attractiveness of passenger flow of conventional buses is gradually decreasing due to problems such as line delivery speed and punctuality.The rail transit card data and bus card data are used to analyze the passenger flow characteristics of existing lines,and a preliminary optimization direction is formulated.Then,the mobile phone data and Internet open map API are used to analyze the characteristics of occupation and residence along the line,the starting and ending points of people passing through the passage,and the special characteristics of connected roads,and the optimization plan is supplemented.Finally,Taking the passenger flow channel of Xinghu Street in Suzhou Industrial Park as an example,the relevant bus lines are optimized.After optimization,the average transportation speed of the main line No.176 has increased from 21.3 km/h to 26 km/h,and the one-way time has dropped from 60 minutes to 40 minutes.
