The invention relates to a lane-level queuing length estimation method based on double-section electronic police data, and the method comprises the following steps: S1, collecting the double-section electronic police data of a downstream target lane and an upstream intersection, and obtaining a matching result through vehicle license plate matching; s2, on the basis of the double-section electronic police data and the matching result, vehicles passing through a downstream target lane are grouped into multiple groups of constrained vehicles and non-constrained vehicles by adopting a dynamic planning algorithm; s3, respectively establishing constraint conditions of non-delay arrival time for the constraint vehicle and the non-constraint vehicle; s4, on the basis of the constraint condition of the non-delay arrival time, the Markov chain Monte Carlo sampling method is adopted to calculate the arrival distribution of the constrained vehicles and the arrival distribution of the non-constrained vehicles; and S5, based on the arrival distribution of each group of constrained vehicles and non-constrained vehicles, estimating the periodic maximum queuing length of the downstream target lane. Compared with the prior art, the method has the advantages of being accurate in estimation, better reflecting the real traffic state and the like.

    本发明涉及一种基于双截面电警数据的车道级排队长度估计方法,包括以下步骤:S1、采集下游目标车道和上游交叉口的双截面电警数据,通过车辆号牌匹配获得匹配结果;S2、基于双截面电警数据和匹配结果,采用动态规划算法将下游目标车道通过车辆分组为多组约束车辆与非约束车辆;S3、针对约束车辆与非约束车辆分别建立无延误到达时刻的约束条件;S4、基于无延误到达时刻的约束条件,采用马尔可夫链蒙特卡洛采样方法分别计算约束车辆与非约束车辆的到达分布;S5、基于各组约束车辆与非约束车辆的到达分布,估计下游目标车道的周期最大排队长度。与现有技术相比,本发明具有精准估计、更好反映现实交通状态等优点。
