| 摘 要： | 可达性是指利用一种特定的交通系统从某一给定区位到达活动地点的便利程度。可达性反映了区域与其他有关地区相接触进行社会经济和技术交流的机会与潜力。本文综合了可达性的主要定量评价方法,并对各种方法的优缺点进行了比较,总结了近期可达性评价方法的进展与动态。随后分别在区域和国家尺度与城市内部尺度上总结了可达性在区域经济发展研究、城市土地利用、社会服务设施提供、城市社会问题等各方面的应用。相对来讲,国内关于可达性的研究尚不丰富。最后,本文阐述了目前可达性研究中的问题,并对未来研究进行了展望。

| Abstract: | Accessibility denotes the ease with which activities may be reached from a given location using a particular transportation system. Accessibility reflects the opportunities and potentialities of a particular region to exchange with other regions. There is a number of accessibility measures, some accessibility indicators are generalized and compared in this paper: time of access to city centre, mean travel costs, opportunity accessibility, economic or population potential. Also, the progress of accessibility measures is reviewed. Accessibility indicators is applied both on regional and metropolitan dimension, such as the regional development, the impact of new infrastructure, the urban land use, the providing of social facilities, the urban social problems, and so on. Relative to the overseas there is rarely research on accessibility in our country. Therefore, some problems are put up in the end and accessibility research needs to be improved. |
