Abstract

The accessibility of urban public transportation reflects the level of development of the public transportation system and provides a favorable scientific support for formulating urban transport planning, optimizing spatial distribution of social service facilities and so on. Applying ArcGis9.3, this article created a public transportation network of Changchun. The shortest accessible time and public transportation service frequency were selected as the indexes of accessibility assessment and we took the off-peak and peak hours as the dividing basis of time. We analyzed the accessibility of residential districts to the hospitals during the peak and off-peak hours. Moreover, this article analyzed the average accessible time of hospital to residential districts during the peak and off-peak hours. The results found that: The overall level of residential districts' average accessible time was higher and the accessibility of off-peak hours was better than that of peak hours. The spatial heterogeneities are conspicuous. The distribution pattern of residential districts' average accessible time shows a discontinuous concentric trend. The shorter the residential districts' average accessible time, the higher the transportation service frequency, but it does not necessarily mean that these two indexes are always consistent. During peak hours, the public transportation service frequency has been significantly improved. The level of hospitals' average accessible time is better during off-peak hours, while in the peak hours there is a remarkable descent. The average accessible time of hospitals at different levels is not identical, but the differences are not significant. On the basis of the above analysis, we examined the problems and reasons of public transportation in Changchun and proposed relevant suggestions.
