摘要
以居民出行调查数据为来源,对通勤者和非通勤者分别建立出行时间模型,分析两类出行者出行时间的分布规律,比较其出行时间对各类影响因素的不同响应程度.研究表明,随机成本边界模型的组合误差结构为研究个体出行时间差异提供了很好的分析手段,能为交通规划和管理工作提供依据.
Travel time frontier models are established for commuters and non-commuters using travel survey data.Model estimation results showed that work activity made travel time pattern of commuters quite different from that of the commuters and that travel time frontiers of the two kinds of travelers had different sensitivity to those influence factors in the model.The notion of minimum travel time provides a powerful framework for estimating the potential capability of a transportation plan or measurement in reducing travel demand from an activity-based time use allocation perspective.And the combination structure of the random effect in the stochastic cost frontier model presents a useful tool for the analysis of individual travel time variation.
