中心城区与周边组团联系的交通策略和交通模式研究——以兰州市白道坪片区为例

兰州市是典型的多中心组团城市,道路网呈混合式发展,城市道路拥堵特征显著.选取兰州市白道坪片区作为研究案例,针对多中心组团城市的交通拥堵问题进行分析和探讨.结合白道坪片区与中心城区交通联系存在的问题,建立了交通可达性模型,通过PyCharm工具,编写了矢量路网和POI(兴趣点)数据爬取程序,然后利用ArcGIS软件完成了数据计算和可视化.根据交通可达性的分析结果,提出了白道坪片区交通发展策略和优化方案.

Study on Traffic Strategy and Traffic Mode of Central Urban Area and Surrounding Groups in Lanzhou

Lanzhou is a typical multicenter group city. Its road network has been developed in mixed way. The characteristics of urban road congestion are significant. Selecting Baidaoping District of Lanzhou as the study example, the traffic congestion of the multicenter group city is analyzed and discussed. Combined with the problems existing in the traffic connection of Baidaoping District with the central urban area, the traffic accessibility model is established. The vector road network and POI (points of interest) data crawling program are compiled by PyCharm tool, and then ArcGIS software is used to complete the data calculation and visualization. Based on the analysis result of traffic accessibility, the traffic development strategy and optimization scheme of Baidaoping District are proposed.
