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W ilson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 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 differentmodes based on minimum of external costs, the equitymodel for different groups based onW ilson entropy assumption, the model forregional equitywith parametersofeconomical leveland price leve,l and the generationalequitymodel forconsidering the change of life quality and preference. These fourmodels from different aspects fully analyze the equity in details, and make itpossible tomodel the equity formathematical evaluation.
