【摘要】：为了解上海市居民通勤现状并改善其薄弱环节,以通勤时间为切入点,调查并分析上海市15个小区的居民通勤出行特征。首先明确通勤方式链定义,分析通勤方式链基本结构和环节组成,将其分为9大类23小类。同时划分4类通勤时间区间以及5类交通态度人群。总结方式链的时空分布规律,考虑主要态度人群"简单安全型"的通勤意愿,以公共汽车、地铁、公共交通组合方式链为例,评价方式链各环节效率。依据感知时间设计通勤者主观评价模型,不同环节通勤时间的改善会存在感知效果的差异。结果显示,接驳和候车是必要且易于改善的重点环节:接驳时间每增加1 min,期望节省时间平均增加0.021 min;候车时间每增加1 min,期望节省时间平均增加0.619 min。
[Abstract]:In order to understand the current situation and improve the weak links of commuting in Shanghai, the commuter travel characteristics of residents in 15 residential areas in Shanghai were investigated and analyzed by using commuting time as the starting point. Firstly, the definition of commuting mode chain is defined, and the basic structure and link composition of commuting mode chain are analyzed, which are divided into 9 categories and 23 subcategories. At the same time, 4 kinds of commuting time interval and 5 kinds of traffic attitude crowd were divided. This paper summarizes the temporal and spatial distribution of the mode chain and considers the commute intention of the main attitude crowd of "simple safety type". Taking the bus, subway and public transport combination mode chain as an example, the efficiency of each link of the mode chain is evaluated. The subjective evaluation model of commuter is designed according to perceptual time. The difference of perceived effect exists in the improvement of commuter time in different links. The results show that the connection and waiting time are necessary and easy to improve: with the increase of the connecting time, the average time saved increases by 0.021 mins, and the average time saved increases by 0.619 mins with the increase of the waiting time by 1 mins.
