引言目前交通流检测点设施布点建设主要是参考行业规范或其他相关规范,结合经验来布设的,这种定性的布设方法,主观意识较强,难免会出现检测器布设数量多、设施点位覆盖路网重复率高、布设不合理等现象。因此科学合理的布设交通检测器设施,以尽可能少的设备覆盖道路网的同时,采集到尽 Introduction At present, the construction of traffic flow detection point facilities is mainly based on reference to industry norms or other relevant norms, combined with experience to layout, this qualitative deployment method, subjective awareness is strong, it is inevitable there will be a large number of detector layout, facilities point coverage Road network repetition rate is high, the layout is not reasonable and so on. Therefore, scientific and rational deployment of traffic detector facilities to cover the road network with as little equipment at the same time,
