公交信息条件下的公交出行意愿研究

摘要

In-depth analysis of influencing mechanism of bus information on the residents travel mode choice is the theoretical basis of rational planning of urban bus travel information environment ,which has important significance for ur-ban traffic management and congestion mitigation .Based on the theory of planned behavior ,at the basis of three basic variables of behavior attitude ,subjective norm ,perceived behavioral control in the theory of planned behavior ,variables of transit information ,personal attributes and travel experience are added to improve the theory of planned behavior .An improved theory of planned behavior is used to build a bus travel willingness model under the condition of bus Informa-tion .With the Nanjing residents as research object ,a structural equation model is used to verify the survey data in order to determine the interaction between various factors and their impact on the willingness of bus travel .The results show that the bus information has significant and positive impact on bus travel variables of attitude ,subjective norm and per-ceived behavioral control with the influencing coefficients of 0 .533 ,0 .451 and 0 .576 respectively ,and that the bus infor-mation has indirect influence on bus travel willingness and the total effect is 0 .92 ,which shows that high quality of the in-formation can improve the appeal of bus and enhance bus travel willingness of residents .%深入解析公交信息对居民公交出行意愿的影响机理，是合理规划城市公交出行信息环境的理论基础，对于城市交通管理以及交通拥堵的缓解有着重要的意义。基于计划行为理论在行为态度、主观规范、知觉行为控制3个基本变量的基础上加入公交信息、出行经验、个人属性等变量，对计划行为理论加以改进，利用改进的计划行为理论建立公交信息条件下的公交出行意愿模型。以南京市居民为调查研究对象，运用结构方程模型对调查数据进行验证分析，确定了各变量的相互作用关系以及它们对公交出行意愿的影响效应。结果表明公交信息对公交出行态度、主观规范、知觉行为控制等变量有直接显著影响，且为正向关系，影响系数分别为0．533、0．451和0．576；公交信息会对公交出行意愿产生间接影响，影响总效应为0．92，说明高质量的公交信息可以提升公交吸引力，增强居民的公交出行意愿。
