The invention relates to the technical field of traffic, and specifically relates to a method and a system for analyzing congestion relationship between roads. The method comprises the following steps: grouping, acquiring time point, acquiring weather, calculating traffic congestion indexes, calculating correlation coefficient and analyzing inter-road influence relation, and matching influence relations among all roads in each group during congestion by utilizing adjacent road groups. Therefore, the influence relationship between the roads during congestion is analyzed. According to the invention, each road is grouped, an independent road network is formed by adjacent roads, a congestion index of each road and a Spearman rank correlation coefficient between the roads are calculated, and whether the adjacent roads are influenced is analyzed when the roads are congested to obtain whether one or more adjacent roads are influenced when one road is congested at a certain moment, so that theroads are also congested. Therefore, better manpower distribution or decision help of traffic dispersion can be provided for traffic polices and traffic departments.

    本发明涉及交通技术领域,具体涉及一种道路间的拥堵关系分析方法及系统,包括以下步骤:分组、时间点获取、天气获取、交通拥堵指数计算、相关系数计算以及道路间影响关系分析,利用相邻道路分组,匹配出在拥堵时,每一组内各道路相互之间的影响关系;从而分析道路间在拥堵时它们之间的影响关系。本发明将每一条道路进行分组,使得相邻道路形成一个独立的道路网,再计算每一条道路的拥堵指数和道路间的Spearman秩相关系数,分析道路在拥堵时是否会影响相邻的道路,得出在某时刻一条道路在拥堵的时候,是否会影响相邻一条或者一条以上的道路,导致它们也发生拥堵;从而可以给交警、交通部门更好的人力分配或者提供交通疏导的决策帮助。
