摘要
组合交通方式相比于单一交通方式的效能优势不仅体现在出行者效用上,更体现在提高交通系统总体效率上,因而时空效能可作为指标综合分析与评估所选择的方式及路径。文章以超级网络为平台分析组合出行各阶段的广义出行费用,建立方式-路径联合模型并求解得到各路径交通分担率,从出行者和决策者的角度提出组合出行时空效能的概念以及计算方法,并通过案例分析评估各线路的时空效能。结果表明:时空效能的高低取决于相组合的公共交通方式,包含地铁的线路时空效能均较高;“公交+地铁”组合方式时空效能值最高为1.13,比只有地铁和只有公交组合方式分别高了5.3%和85.4%;“短距离+长距离”和“中距离+长距离”的组合出行中,地铁的时空效能优势要远高于其他方式。
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.
