考虑不同群体特征的通勤者出行选择行为影响研究

The Influence of Commuters Travel Mode Choice Behaviour Considering Characteristics of Different Groups

为细化探究不同通勤群体的出行选择行为影响机理,利用RP和SP调查方法获取通勤者出行信息并分析不同群体出行时空分布特征,从主客观维度选取个体属性、出行属性和公交使用意愿等出行方式选择影响变量,面向全体通勤人群和低频公共交通通勤人群利用结构方程模型实现出行选择行为影响关系的解析。研究结果表明:不同通勤人群的个体属性与出行属性因素均对其出行选择行为具有显著影响作用,且全体通勤人群的个体属性与出行属性因素间具有相关联关系0.12;低频公共交通通勤人群较全体通勤人群的出行属性因素对出行选择行为具有更大的负向影响作用-0.79;职业和月收入、性别,以及出行距离和性别分别为全体、低频公共交通通勤人群出行选择行为影响最大、最小的观测变量。

To explore the influence mechanism of travel mode choice behaviour of different commuter groups in detail,the spatial and temporal distribution characteristics of commuters travel were analyzed based on RP and SP questionnaires data,and the influencing variables of travel mode choice such as individual attributes,travel attributes and public transport use intention were selected from subjective and objective dimensions.Then,the structural equation model is used to analyze the relationship between commuters travel mode choice for all commuters and low-frequency public transport commuters.The structural equation model is used to analyze the relationship between commuters travel mode choice behaviour for all commuters and low-frequency public transport commuters.The results show that the individual attributes and travel attributes of different commuters have significant effects on their travel mode choice behaviour,and the correlation between the individual attributes and travel attributes of all commuters is 0.12.The travel attributes of low-frequency public transport commuters have a greater negative effect-0.79 on travel mode choice behaviour than that of all commuters.Occupation and monthly income,gender,are the observed variables that have the greatest and least influence on the travel mode choice behaviour of the whole commuters,respectively;while that for the low-frequency public transport commuters are travel distance and gender.
