探索城市群通道出行特征对于优化通道资源具有重要意义。为获取城际通道多方式、多时段、高样本量的出行特征数据,基于手机信令数据识别城市群通道出行的原理,研究了通道出行特征指标提取方法。以成渝城市群中重庆至合川通道为例,利用手机信令数据分析了通道出行特征和时空规律。结果表明:重庆至合川通道平均出行总量为3.9万人次,出行强度为1.19,通勤出行占比为7.2%,私家车出行占比为84%,出行时间主要集中在早高峰。研究为城市群运输通道系统优化、资源配置和产业布局规划的数据获取提供了一种新思路。
It is of great significance to explore the travel characteristics of urban agglomeration channel to optimize the access resources. In order to obtain multi-modal, multi-period and high-sample travel feature data of inter-city channel, the principle of urban cluster channel travel was identified based on cell phone signaling data and the method of extracting travel channel feature index was studied. Taking Chongqing-Hechuan Passageway in Cheng-Yu urban agglomeration as an example, this paper analyzes the travel characteristics and space-time rules of passageway by using mobile phone signaling data. The results showed that the average travel volume from Chongqing to Hechuan was 39,000, the travel intensity was 1.19, commuter travel accounted for 7.2%, private car travel accounted for 84%, and the travel time mainly concentrated in the morning peak. The research provides a new idea for the data acquisition of urban corridor transportation system optimization, resource allocation and industrial layout planning.
