| 中文摘要: |
| 考虑出行者有限理性的特点，建立改进的交通方式划分模型．通过问卷调查，确定出行者方式选择各影响因素的权重，以及各交通方式在不同因素下的表现；运用TODIM方法，计算各交通方式的价值；基于有限理性，建立交通方式选择Probit模型；讨论模型中参数变化对交通方式划分的影响；对比上班和购物出行，分析不同出行目的对方式选择的影响．研究表明，基于有限理性的交通方式划分模型能够体现不同出行目的下出行者出行方式选择偏好；参数 θ 体现出行者的认知程度，在该模型里应在(0,2)中取值． |

| An improved traffic modal split model is proposed considering travelers′ bounded rationality. The weights of influence factors to mode choice and the evaluations of traffic modes against each factor are defined through a questionnaire survey. The value of each traffic mode is calculated by TODIM method. A Probit model of traffic mode choice is proposed on the basis of bounded rationality. The impact of parameters′ change of the model on traffic modal split is discussed. Comparing working and shopping, the influence of different travel purposes on mode choice is analyzed. Experimental results show that the traffic modal split model based on bounded rationality can reflect travelers′ preference of mode choice under different travel purposes. The parameter θ represents travelers′ cognition level, and in this model θ should be valued in (0, 2). |
