基于京津旅客出行特征的城际铁路通勤出行研究

Study on Intercity Railway Commuting Based on the Characteristics of Beijing-Tianjin Passengers' Travel

本研究以京津城际高速铁路旅客出行行为作为研究对象,基于1500份旅客调研问卷及实证调查,从旅客社会经济属性、出行交通方式、出行时空分布、出行体验等方面分析城际旅客出行行为,并对通勤族这一特定人群出行特征进行重点分析。研究表明:京津城际客流主要为商务出行及休闲旅游,跨城通勤比例较低,以男性、中青年、高收入群体为主,受出行时间、出行成本、城市内部交通接驳方式等因素约束。城际铁路客流的分布受城市功能分区及站点辐射范围的影响,现阶段京津城际客流主要集中于北京与天津的中心城区,而远郊区县城际出行较为分散与稀疏。受通勤时间及通勤成本约束,京津通勤旅客更多以周为单位往返两地,日通勤旅客占比较低。京津两地尚未形成区域跨城"1小时"通勤,主要原因为除城际列车行驶时间以外的出行及等候时间较长,通勤交通效率较低。

The object of this research was passengers＇ behaviors who were taking a train of Beijing Tianjin intercity highspeed railway. To find out the characteristics of Beijing Tianjin intercity travel behaviors the research analyzed economic attributes, travelling purpose, travel frequency, travel time and space distribution and travel experience of passengers based on 1500 questionnaires of the passengers and empirical investigation. The results show that： firstly, the Beijing-Tiaajin Inter-city Passenger Flow mainly for business travel and leisure tourism, number of inter-city commuting is relatively low, most inter-city commuters were featured by male, young, high-income groups and restrained by the travel time, travel cost and inter-city transport interchange facilities and other constraints. Secondly, The distribution of inter-city railway passenger flow is affected by city function zoning and radiation range of station. At the present, the Beijing-Tianjin Inter-city Passenger Flow is mainly concentrated in Beijing and Tianjin＇ s central districts, while the suburban districts and counties are scattered and sparse. Thirdly, Limited by constraints ,such as commuting time and cost, most of the beijing-tianjin commuter passengers commute in week, commuter passengers commute in day is small. Fourthly, Beijing and Tianjin have not yet formed ＂1 hours ＂commuting between two cities, mainly due to extra travel time and waiting time have been spent, commuting traffic is unefficient
