摘要
研究目的:对交通公平性的衡量角度加以区分并分别建立相应的量化评价模型。研究结论:从不同交通方式之间、不同群体之间、不同地区之间、不同代际之间4种衡量角度出发,探讨了交通公平性问题的理论本质和表现形式。在此基础上建立了数学模型用于描述上述公平性问题,其中包括基于外部成本最小化的不同交通方式之间的公平性评价模型、基于Wilson熵分布假设的不同群体效益归属公平性的评价模型、以地区经济发展水平、物价水平等为基本参数的地区公平性评价模型,以及考虑生活质量变化和偏好比率的代际公平性判别模型。4种衡量角度区分使交通公平性分析得到细化并更加全面,数学模型的建立使量化评价交通公平性成为可能。
Research purposes： The mathematical models are offered for evaluation of the transportation equity in this paper. Research conclusions：The analyses of theoretical essence and representation format for the transportation equity are made from the aspects of different transportation modes, different social groups, different regions, and different generations. The various models are offered for the equity, including the equity model for different modes based on minimum of external costs, the equity model for different groups based on Wilson entropy assumption, the model for regional equity with parameters of economical level and price level, and the generational equity model for considering the change of life quality and preference. These four models from different aspects fully analyze the equity in details, and make Key it possible to model the equity for mathematical evaluation.
