出行时耗的规律及启示

出行时耗是指人们用于出行的时间.城市居民一天出行的平均时耗是否具有一定的稳定性,或者是否存在固定的出行时耗预算,多年来一直是城市交通领域工作者的研究热点之一.首先,在回顾国外相关研究的基础上,分析说明我国城市居民人均日出行时耗的规律性.通过近2年国内几个城市的调查数据,说明出行时耗稳定性在集计水平上是存在的.最后,综合分析了出行时耗稳定性的形成机理及出行时耗稳定性对于交通系统建模与分析的启示.

Patterns and Their Implications of Travel Time

Travel time is the time consumed during a trip or trips made routinely. For residents in urbanized areas, whether their daily travel time is stable or they have a constant travel time budget has been one of the focuses of research for many years. This paper reviews the findings in travel time stability studies published abroad, and analyzes the patterns of travel time seen in Chinese cities. Recent survey data from several Chinese cities show that the travel time stability exists at an aggregated level. The reasons behind this stability and its implications are discussed as well.
