摘 要: 针对城市公交系统的公众评价问题,提出了偏最小二乘通径模型.通过该模型能够方便地确定潜变量与观测变量之间的关系,分析变量对城市公交系统整体性能的影响,以及有效处理变量的多重相关性问题.根据有关问卷调查数据,对此模型进行了验证.实例分析表明,该模型更有效、更全面,具有良好的应用前景. A partial least squares path model is proposed to solve the problem for public evaluation of urban transit systems. This model is able to help to conveniently identify the relationships between the latent variables and the observable variables, to analyze the impacts of these variables on the overall performances of urban transit systems, and to effectively handle the multi-correlation problem of the variables. The model has been justified based on the relevant questionnaire data. It is demonstrated that the proposed model is more effective and comprehensive, showing a good application prospect.
