摘要: 运用流体动力学和交通工程学基本原理建立了城市道路动态资源的计量模型。基于城市智能交通数据采集系统采集的动态交通信息,运用城市地理信息系统(GIS)相关方法,对上海市内环内城市道路资源进行可视化描述,分析了城市道路资源的瓶颈地带;对深圳市道路运行状态进行了分析和评价,结果显示深圳市城市道路中支路基本符合规划预期,主干道则部分偏离规划预期。

Abstract: Based on hydrodynamics principle,the model for the dynamic resource of the urban road network is proposed in this paper.The resource of Shanghai urban road network is displayed visually with GIS(Geographical Information System) and the information from ITS(Intelligent Transportation System),then the bottleneck of the urban road network is analyzed from the view of urban dynamic road resource.Based on the dynamic urban traffic information from ITS and the model,this paper evaluates the traffic condition of the road link,results show that the condition of the branch road in Shenzhen city is in accord with design standards and that of the arterial road is not in good condition.
