基于可达性的绿色交通发展环境评估研究

Research on Assessment of Green Traffic DevelopmentEnvironment Base on Accessibility Theory

摘要: 绿色交通发展模式是国内大多数城市认可并极力倡导的，不少城市制定了绿色交通发展目标，但是没有一种很好的方法去评估绿色交通发展的环境。针对城市中的日常出行活动，提出以城市建筑物为研究对象，通过城市活动场所、公交站点以及公交线路三个方面的累计机会可达性来评估城市绿色交通发展环境的方法。以深圳福田区为例，收集福田区建筑、服务设施，道路网络及公共交通线路信息，建立GIS模型并选取11个社区，评估社区之间的绿色出行环境差别，并对社区的道路网络，建筑密度及服务设施密度进行了分析比较，希望能对今后城市发展中绿色交通规划和建设工作提供参考。

Abstract: Green traffic development model is most recognized and strongly advocated by domestic cities. Many cities have made green traffic development plans and goals, but there are no good methods to assess their green traffic development situations. For urban non-commute traffic, this paper presents a method that integrated city building’s walk accessibility of service facilities, walk ac-cessibility of bus stop and public traffic accessibility to evaluate urban green traffic development environment. We build a GIS model of Shenzhen Futian and the model includes the information of Futian buildings, service facilities, road network and bus lines. Bases on the model, the paper ana-lyzes the differences of green traffic development environment of 11 communities and finds that road network density, building density and service facility are key factors to promote low carbon travel. The results can be helpful for urban land planning and green traffic planning.
