城市不同空间通勤行为可转移性研究

通勤者因地域及个体特征差异造成选择行为显著不同,本文旨在识别这一差异并揭示城市不同空间通勤行为的可转移性.在分析上海市通勤出行行为影响因素基础上,建立融入OD(Origin and Destination)变量的全空间及分OD空间的通勤方式选择模型,依据转移度量指标研究通勤出行模型空间可转移性.结果表明:全空间模型不能准确揭示不同出行空间通勤行为差异,除全空间模型可转移至内环外—内环内出行空间外,其他空间模型均不可转移;此外,各空间通勤者更偏好常规公交、地铁,且不同出行空间通勤者偏好存在显著差异.

Transferability of Commute Behavior across Different Spaces within Metropolis

Commuters have significantly different behaviors due to differences in geographical and individual characteristics. This paper aims to identify this discrepancy and to reveal commuter behavior transferability between difference spaces. Based on the influence factor analysis of Shanghai commute travel behavior, WS (Whole Space) model incorporating OD (Origin and Destination) variable, different OD models are established to study commute travel model space transfer applicability according to transferability measurement indicators. Results show that WS model cannot reveal the commute travel behavior differences across ODs. Except that WS model can be applied to the OD originating from outside and ending within the inner ring area, other OD models are not transferable. Besides, commuters from different ODs prefer bus and subway with significant differences.
