摘要:

国内以往关于城市空间结构与居民出行行为之间关系的研究主要建立在出行角度的分析之上,以巡回作为基本单元,从出行决策视角探讨居民出行时空间决策社区分异的研究尚少见报导。利用2007年北京市居民活动日志调查获取的第一手数据,构建基于巡回的出行时空间决策概念模型,并采用嵌套Logit对北京市居民工作日出行时空间决策的社区分异进行探讨。结果表明:居民巡回类型决策的社区分异较为显著,但会随出行目的变化而发生较大变化;巡回中主要活动起始时间决策的社区分异并不显著,但起始时间与活动类型存在较强的内在联系;出行距离及交通方式决策的社区分异较为显著,对单位社区及政策性住房社区应给予更多的研究和关注。

Abstract:

The relationship between built environment and travel behavior has long been studied in geography, transportation and city planning. There has been a large body of such researches in western countries from macro and micro perspectives, using different methods such as simulation, description and modeling. Relatively, in China most such researches have centered on trip-based analysis, no matter from aggregation level or individual level, paying little attention to tour-based analysis. In addition, the travel decision-making process of residents has rarely been considered either. This paper attempts to construct the concept model of tour-based spatio-temporal decision-making of travel behavior and explore its residential differentiation on workdays in Beijing city, by using nested logit model with the data of travel diary obtained in 2007. Moreover, it attempts to discuss the relationship between activity and mobility.The results first of all show that residential neighborhood has an effect on the tour type decision-making, but the effect varies with the change of travel purpose. For example, if it is a work tour, its residential differentiation will be significant; but if it is a non-work tour, it will be indistinct. This may be closely related with Chinese unique suburbanization. Secondly, the start time decision-making is mainly affected by the activity type, which implies that there is a strong tie between activity and mobility. But, anyhow, the residential differentiation of start time decision-making is not significant. Thirdly, the travel distance and mode choice is distinct in different neighborhoods, that is to say the residential differentiation of spatial decision-making is significant. On the whole, the travel distance of Danwei residents is comparatively short, and the mode choice is mainly non-motor vehicle. In contrast, the travel distance of residents in commercial housing community and policy-oriented housing community is much longer, and the mode choice is mainly motor vehicle, with car in the former and public transport in the latter. Therefore, the travel behavior of Danwei residents is to some extent low carbon while the travel of policy-oriented housing community residents is long and dependent on public transport. We should pay more attention to these unique neighborhoods in China.
