摘要:

运动出行(Active Travel或Active Mobility,AT或AM)是一种以出行者自我为驱动的出行方式,由于其占用道路面积小、机动性强、可持续性好,因此对缓解城市交通压力、改善城市交通的时空不合理性起着至关重要的作用。文中首先研究了运动出行的定义和内涵;其次从影响运动出行的时空条件出发,以点和线的视角将时间与空间拆分成出发时间、出行时间、出行距离与建成环境4类约束条件,依次阐述不同类型的时空条件特征,并对运动出行与时空约束间的潜在联系进行分析;接着以单一约束和多种时空组合作为切入点,分析其对运动出行的影响;通过归纳发现,时空约束对运动出行的影响比传统认知中更为复杂,主要呈非线性关系且存在相应的理论阈值;最后提出当前理论研究中的不足之处及未来的研究方向。文章旨在归纳时空对运动出行的制约作用,展示不同时空约束作用下运动出行的具体变化规律,以期改变城市出行者的固有思维,提高运动出行的分担率,促进城市交通出行结构的进一步优化。

Abstract:

As a self-driven travel mode, active travel or active mobility (AT or AM) plays a crucial role in alleviating urban traffic pressure and improving the temporal and spatial irrationality of urban traffic because of its small road occupation area, high mobility and good sustainability. The paper firstly studied the definition and connotation of active mobility. Secondly, starting from the spatiotemporal conditions affecting active mobility, it splited time and space into four types of constraints, namely, departure time, travel time, travel distance and built environment from the perspective of point and line, and expounded the characteristics of different types of spatiotemporal conditions in turn. It also analyzed the potential connection between active mobility and spatiotemporal constraints, and analyzed constraints influence on active mobility with single constraints and multiple spatiotemporal combinations as the entry point. Through summarization, it is found that the influence of spatiotemporal constraints on active mobility is more complicated than that in traditional cognition, and it is mainly a non-linear relationship and some of indexes have corresponding theoretical threshold. Finally, it put forward the shortcomings of the current theoretical research and the future research direction, which will provide a reference for the subsequent research. The purpose of this paper is to summarize the role of spatiotemporal constraints on active mobility, to show the specific change rule of movement travel under the role of different spatiotemporal constraints, aiming at changing the intrinsic thinking of travelers, improving the sharing rate of movement travel, and optimizing the travel structure of urban transportation.

Key words: urban traffic, spatiotemporal constraint, active mobility, spatiotemporal combination
