基于方式-路径模型的组合出行时空效能分析
Spatio-temporal efficiency analysis of combined travel based on mode-route model
摘要
Abstract
The efficiency advantage of combined transportation mode compared with single transportation mode is not only reflected in the utility of travelers,but also in improving the overall efficiency of the transportation system.Therefore,the spatio-temporal efficiency can be used as an indicator to comprehensively analyze and evaluate the selected mode and route.This article analyzes the generalized travel cost of each stage of combined travel on the platform of a super network,establishes a mode-route joint model,and solves for the traffic sharing rate of each path.It proposes the concept and calculation method of spatio-temporal efficiency for combined travel from the perspectives of travelers and decision-makers,and evaluates the spatio-temporal efficiency of various routes through case studies.The results show that the spatio-temporal efficiency depends on the combination of public transportation modes,with metro routes having generally high spatio-temporal efficiencies.The spatio-temporal efficiency value of the"bus+metro"combination is highest at 1.13,which is 5.3%higher than the combinations with only metro and 85.4%higher than those with only buses.In combined short-distance and long-distance or medium-distance and long-distance travel,the spatio-temporal efficiency advantage of the metro is much higher than other modes.关键词
