通勤交通方式链适应性评价与优化导向

Adaptability Evaluation and Optimization Guidance of Commuting Traffic Mode Chain

摘要:

从通勤者视角，将通勤距离分为长、中、短3组，采用统一的出行时耗可接受度评价标准，从门到门行程速度、广义成本、可靠性、满意度和选择比例分别分析不同通勤距离分组下各方式链的行程速度、可靠性、广义成本与满意度相关性，基于相关性分析结果建立适应性好的方式链判断标准.根据这一判断原则，挑选出通勤距离分组下适应性好的方式链类型, 以适应性好的方式链所具有的特征指标为参照对象、公共交通优先发展为约束条件，提出通勤距离长、中、短分组中各交通方式链优化导向，为通勤交通服务质量的改善提供决策参考.

Abstract:

From the perspective of commuters, the commuting distance was divided into three groups including long, medium and short commuting distance and a unified evaluation criteria about the acceptability of travel time was used in this article. From five dimensions of door-to-door travel speed, general cost, reliability, satisfaction and choice ratio, various traffic mode chains in three group of distance are analyzed. Based on the results of correlation analysis between the travel speed, reliability, general cost and satisfaction for each group of commuting distance, judgment criterion of the adaptability was established and the traffic mode chain with good adaptability was selected. Finally, with the characteristic of the traffic mode chain with good adaptability as reference objects, optimization guidance for each traffic mode chain in long, medium and short commuting distance was proposed under the constraint on prior development of public transport, which was used to provide decision reference for the improvement of commuting traffic service.
