摘要
以核心家庭为研究单元,运用苏州市2009年城市居民出行调查数据,以个人家庭属性为外源变量,家庭各类型活动时耗和出行时耗为内生变量,建立了深入揭示三者相关关系的结构方程模型.研究结果表明,个人家庭属性对家庭的活动和出行时耗有显著的影响;各类型的活动时耗和出行链出行时耗之间也相互影响;此外,模型还验证了个人家庭属性通过影响活动参与间接影响出行行为.研究家庭整体的活动和出行链行为有利于分析家庭共同的活动-出行决策机制,有助于从家庭整体角度理解活动和出行链的决策行为.
Taking a nuclear household as a unit,structural equation model is developed based on the data from the activity-travel survey conducted in 2009in Suzhou.Exogenous variables are household socio-demographics,and endogenous variables consist of household activity duration and trip-chaining travel time.The results indicate that household socio-demographics have remarkable influences on household activity duration and travel time.Additionally,there are interactions among different kind of household activity durations and trip chains travel time.Further,socio-demographics have indirect effects on household travel time through activity duration.
