The invention relates to the technical field of road traffic control, in particular to a road traffic planning method, which comprises the following steps of: acquiring a historical traffic flow curve of each road in each day, and further determining the traffic flow retentivity in the same time period; determining the traffic flow correlation degree of any two roads according to the difference between the historical traffic flow curves of any two roads in each day and the traffic flow retention degree of any two roads in the same time period; determining the clustering optimization weight of any two intersections according to the traffic flow correlation degree, clustering all intersections of the to-be-planned urban area, obtaining an optimal intersection clustering result, and regulating and controlling traffic lights at the intersections; according to the method, the clustering optimization weight is determined by quantifying the traffic flow correlation degree of the road, and the conventional intersection clustering result is optimized, so that the reliability of intersection traffic light regulation and control is improved, and the rationality of road traffic planning is further improved.
本发明涉及道路交通控制技术领域,具体涉及一种道路交通规划方法,包括:获取每条道路在每天内的历史车流量曲线,进而确定同一时段下的车流量保持度;根据任意两条道路在每天内的历史车流量曲线之间的差异情况和任意两条道路在同一时段下的车流量保持度,确定任意两条道路的车流量关联度;根据车流量关联度确定任意两个路口的聚类优化权重,进而对待规划城市区域的所有路口进行聚类,获得最优路口聚类结果,进而调控路口红绿灯;本发明通过量化道路的车流量关联度确定聚类优化权重,对常规的路口聚类结果进行优化,以提高路口红绿灯调控的可靠程度,进一步提升了道路交通规划的合理性。
