【摘要】 针对城市路网中各等级道路功能不合理和交通拥堵问题,提出了一种城市路网研究的方法:利用移动检测技术在道路上采集动态交通数据,通过对采集的数据进行处理,地图匹配,在地图上重现车辆运行轨迹,再结合城市土地利用情况,对城市路网状况进行综合微观分析,探讨了不合理路线的种类和原因,提出针对性的路网改良方案和建议.更多还原

【Abstract】 To analyze the unreasonable usage of all levels of roads and the formation of traffic jams,the paper advances a method to estimating urban road network state:.Using probe vehicle technology to collect real-time traffic data, and after pre-processing,map matching,and considering the land use conditions,the traffic data have been used for microscopic analysis on urban road network.Some corresponding schemes and suggestions are proposed on urban network improvement.A discussion on the unreasonable routes has also been developed.更多还原
