家庭成员活动-出行选择行为的相互影响

基于活动的方法对研究家庭成员活动-出行选择之间的相互影响关系提供了新的思路。针对已有研究多围绕发达国家展开的现状,以国内某直辖市2005年居民出行调查数据为来源,从基于活动方法的协作性限制出发,研究了主要家庭成员活动-出行选择之间的相互影响模式,利用结构方程模型,分析了活动和出行需求在家庭成员之间的分配情况,讨论了存在于同一成员和不同成员各次活动和出行中的替代、补充、陪同等影响关系对个体活动-出行选择行为的影响。研究得到了在行为学上具有较强解释力并达到各项统计学评价指标的模型,对出行行为分析有重要意义。

Research on Activity-Travel Choice Behavior Interactions between Household Heads

Activity-based method is becoming more sophisticated in the representation of intra-household interactions and constraints that influence individual activity-travel choices.However,most of the studies focus on residents of developed countries.Using the travel survey data of a municipality collected in 2005,this study examines inter-person interactions between heads of households.Daily work and non-work activity and related travel allocations between the two household members are analyzed using a structural equations model.Substitution,companion,and complementary relationships involving both activities and the associated travel between the heads of household are also examined.The model estimation results offer significant coefficients and reasonable interpretations consistent within Chinese context.This study captures strong interactions and task allocation among household members and their significant effects on members’ work and non-work activity and travel time allocation decisions.Results from this research are of significance for travel behavior analysis.
