The Measurement Method and Spatial Differentiation of Urban Transport Equity
基于GIS提出城市交通公平的测度指标和方法,以昆明52个社区为例,发现公交可达性差异是不同收入群体交通公平空间分异的主要影响因素。
Precise recognition of urban transport equity spatial differentiation features is the precondition for transport equity improvement. Based on explaining the connotation of transport equity, the measurement indexes for urban transport equity spatial analysis were proposed considering traffic location, transport mode and travel group difference.The measurement methods of accessibility and spatial balance degree of different transport modes, and transport equity of different groups were also proposed based on GIS. 52 residential communities were chose considering different traffic location in Kunming, and the transport equity spatial differentiation feature was obtained based on GIS with real data.Results indicate that the three measurement indexes included accessibility, transport mode accessibility index and trips location entropy could represent transport equity spatial differentiation feature effectively; the difference of bus accessibility was the great influence factor for transport equity spatial differentiation between difference income grade groups; the bus trip group in the area which outside of third ring road in Kunming has to suffer the most seriously transport inequity.
