According to the method and the system, based on a road network topological structure, by taking minimization of the number of feasible edges of a road network as an optimization target and taking the number of checkpoints and the coverage rate of checkpoint information as constraint conditions, a checkpoint layout optimization model aiming at road network intersections is established, and an optimal combination of checkpoint layout is obtained through solving. According to the method, the checkpoint layout evaluation index is introduced, the optimization result is subjected to correlation analysis and evaluation, richer traffic information can be conveniently obtained, the continuity of checkpoint monitoring is effectively improved, and the method has great application value for realizing high-accuracy vehicle trajectory reconstruction.

    本发明公开了一种卡口布设优化方法及系统,基于路网拓扑结构,以最小化路网可行边数为优化目标,以卡口数量和卡口信息覆盖率为约束条件,建立了针对路网交叉口的卡口布设优化模型,求解得到卡口布设最优组合。本文引入了卡口布设评价指标,对优化结果进行了相关分析与评价,便于获取更加丰富的交通信息,有效提升卡口监测的连续性,对于实现高准确率的车辆轨迹重构具有很大的应用价值。
