Abstract:

To improve the transportation equity of urbanization areas, manifestation and causes of transportation equity of urbanization areas are analyzed based on the urban transportation equity theory. In view of the differences between urbanization areas and metropolitan areas, this paper evaluates the traffic fairness from the perspective of accessibility based on the deprivation theory. Measurement methods of traffic trip tolerance degree threshold, expectation threshold, spatial accessibility, etc. are put forward, and a quantitative model is proposed to measure the influence based on the absolute deprivation theory and relative deprivation theory. Calculation result shows that the absolute deprivation degree and relative deprivation degree of urbanization areas residents have been effectively evaluated by transportation equity evaluation model based on the deprivation theory. The paper indicates that lack of transportation infrastructure is normal in urbanization areas, and improvement measures of transportation equity should pay more attention to traffic policy adjustment, public transportation system improvement and psychological guidance for urbanization areas residents.

Key words: systems engineering, transportation equity evaluation model, deprivation theory, traffic deprivation model, rapid urbanization, potential measure model

摘要：

为改善快速城市化地区的交通公平性，基于罗尔斯正义原则，分析了快速城市化地区交通公平内涵.基于剥夺理论从可达性角度进行了交通公平评价，并提出居民出行容忍度阈值、期望阈值及交通小区可达性等数据的测度方法，从绝对剥夺与相对剥夺两个层面建立交通公平评价模型，并通过算例进行验证分析.算例分析结果表明，基于剥夺理论的交通公平评价模型可以有效测度快速城市化地区居民的交通绝对剥夺感与相对剥夺感，指出交通基础设施缺乏是快速城市化地区的一种常态，应当从交通政策调控、优化公交系统和居民心理疏导三方面改善快速城市化地区的交通公平.
