基于态度-行为模型的低收入通勤者出行方式选择

摘要

To analyze modal choice behavior of low income commuters and reveal the influence of individual’s socio-demographics, activity attributes and latent attitude variables on mode choice, an integrated attitude-behavior model is utilized to estimate these relationships based on Fushun activity-based travel survey. Firstly, based on a multiple indicators multiple causes model to analyze effects of explanatory factors on attitude variables, results indicate gender, age and driving license possession play important roles on attitude formation. Then, multinomial Logit models with and without latent variables are both estimated. Findings show that the latent variables enriched choice model provides additional explanation on travel behavior. Socio-demographics, activity attributes and attitude variables exert different impacts on low income commuters’mode choice.%为了分析城市低收入通勤者交通方式选择行为，揭示个体社会经济属性、活动属性和潜在态度变量对出行者出行方式选择的影响，基于抚顺市居民一日出行调查数据，采用态度—行为模型探究低收入通勤者出行方式选择机理。首先基于多指标多原因模型分析影响态度变量的外在因素，结果表明性别、驾照拥有情况和年龄对态度变量的构成影响较大。然后，分别建立含潜变量和不含潜变量的多项Logit模型，发现含潜变量的选择模型更能解释出行行为，社会经济属性、活动属性和态度变量对低收入通勤者出行方式选择影响存在一定差异。
