The invention provides a target road congestion determination method and system in smart traffic, and relates to the technical field of road congestion determination, and the method comprises the steps: carrying out the meshing of a target region, so as to obtain a grid list A corresponding to the target region; traversing A, and determining grids which have overlapped areas with a target road on which the user vehicle travels as specified grids, so as to obtain a specified grid list B; obtaining a vehicle density list rho corresponding to the B; traversing rho, and if rho j is greater than lambda1, determining Bj as a congestion grid; if rhoj is greater than or equal to lambda2 and less than or equal to lambda1, determining Bj as an undetermined grid; determining whether each to-be-determined grid is a congested grid or not; determining whether the target road is congested according to the number of the congested grids and the distance between the actual area corresponding to the congested grids and the user vehicle; according to the invention, the computing power consumption can be reduced, and the efficiency and accuracy of determining the road congestion are improved.

    本发明提供了一种智慧交通中目标道路拥堵确定方法及系统,涉及道路拥堵确定技术领域,方法包括:将目标区域进行网格化,以得到目标区域对应的网格列表A;遍历A,将与用户车辆行驶的目标道路存在重合区域的网格确定为指定网格,以得到指定网格列表B;得到B对应的车辆密度列表ρ;遍历ρ,若ρj>λ1,则将Bj确定为拥堵网格;若λ2≤ρj≤λ1,则将Bj确定为待定网格;确定每一待定网格是否为拥堵网格;根据拥堵网格的数量以及拥堵网格对应的实际区域与用户车辆之间的距离,确定目标道路是否拥堵;本发明能够降低算力消耗,提高确定道路拥堵的效率及准确性。
