城市公共交通可达性评价方法研究--以珠海市为例

Evaluation of Urban Public Transportation Accessibility:Taking Zhuhai as an Example

对城市公共交通可达性服务水平进行有效评估,对于优化城市公共交通资源配置,更好地满足居民公共交通出行需求有重要意义。在梳理现状公共交通可达性服务水平评估方法的基础上,综合考虑公共交通设施可达性、公共交通站点服务能力和区域可达性,建立城市公共交通可达性服务水平指标。对珠海市交通小区的公共交通可达性进行定量评估,分析交通小区公共交通服务水平与人口密度的适配性。结果表明,可达性空间分布格局符合当地实际公共交通资源配置特征,公共交通可达性空间分异特征显著。最后,针对现有公共交通系统存在的问题提出相应的改善思路,为深化落实公交优先发展战略以及强化支撑引导城市空间发展提供指导。

The effective evaluation of the accessibility services level of urban public transportation is of great significance to optimize the allocation of urban public transportation resources,and to better meet the residents travel demands.On the basis of combining the existing public transportation accessi-bility service level evaluation methods,the accessibility of public transportation facilities,service ca-pability of public transportation stations,and regional accessibility are comprehensively considered to establish the index for accessibility service level of urban public transportation.The method is used to evaluate the public transportation accessibility in the Zhuhai traffic zones so as to discuss the adapt-ability between the level of service of public transportation and the population density.The results show that the spatial distribution of accessibility conforms to the local public transportation resources allocation characteristics,and the spatial differentiation characteristics of public transportation accessi-bility are significant.Finally,according to the problems of the existing public transportation system,the paper puts forward improvement measures which can provide guidance for implementing the pub-lic transportation priority development strategy and strengthening support for urban spatial develop-ment.
