大城市支路网合理密度及管理对策

支路是城市道路网系统重要的组成部分,正如人体的毛细血管一样。通过对支路交通的功能分析,从面积密度及平均间距2个方面计算并提出大城市支路网的合理密度指标;从加强支路与其它道路的衔接、提高利用率、完善交通工程设施及加强运行管理4个方面提出相关对策,分为规划阶段加强对支路网的研究、三维一体的引导、完善设施及加强日常的养护管理等方面。研究成果将为支路的规划、建设及运营管理提供技术支持。

Reasonable Density and Management Measures for Local Roads in Big Cities

Local roads play a very important role in urban road network,just as capillaries do in human bodies.After functional analysis of local roads,a reasonable density index criterion was suggested based on calculating the area density and average spacing.In addition,management measures of four aspects were proposed,which are to improve the connection between the local road and other roads,raise the utilization rate,increase the transportation infrastructure investment and strengthen the operation and management.Proposed measures include special emphasis on the local roads in the stage of planning,three-dimensional integrated guide,facilities improvement and regular maintenance and management.The findings in this research may provide some technical support in local roads planning,construction and operational management.
