摘　　要：利用深圳市浮动车GPS数据,从路网、不同等级道路、交叉口3个层面分析城市道路网实际使用状况。结果表明：1影响路网交通流分布规律的因素有时间、道路自身属性、区位因素、直接相连的上级道路速度等;2从不同类别速度的道路长度配比发现深圳次干路的实际运行速度偏低,与《城市道路交通规划设计规范》设定存在一定的偏差;3交叉口对城市道路交通流的影响范围大致为100 m之内,35~40 m为交叉口平均排队长度,不同类型交叉口的参考数值存在差异。In depth study of the use of the road system,so as to carry out an empirical test by using the current situation of traffic operation on the road design specifications and related indicators. Evaluating the urban road network by using the massive objective spatio-temporal data will help to summarize the rationality of the existing transportation planning concept,the related technical basis and the design specifications. Using the floating car data of Shenzhen city,the distribution of urban traffic flow,its affecting factor as well as the relationship with road construction are analyzed from three aspects,including the road network,different levels of roads,and roads intersection. The results show that： 1 Factors affecting the spatio-temporal distribution of traffic flow include the time,road itself attributes,location factors,the speed of higher level road connected directly. 2 By analyzing the speed of different types of road length ratio,we find that actual operating speed of sub-distributors is low which indicates there is some irrationality in Road Design Standard. 3 The intersections of urban roads usually affect the near traffic flow within 100 meters,and the average queue length of intersections is about 35 ~ 40 m.
