The invention provides a target intersection traffic signal optimization method and system. The target intersection traffic signal optimization method comprises the following steps: S1, classifying completed case intersection signal optimization schemes according to intersection problems, and establishing an optimization scheme database; s2, calculating the similarity Si of the target intersection and each case intersection on the same intersection problem according to the target traffic data of the target intersection and the reference traffic data of each case intersection in the optimization scheme database; s3, determining intersection problems of the target intersection according to the similarity Si, and taking a case intersection corresponding to the maximum similarity value in the intersection problems as a matched intersection of the target intersection; and S4, extracting an optimization thought for solving the intersection problem of the target intersection at the intersection of the case, and outputting a traffic signal optimization scheme of the target intersection. According to the method, the optimization scheme closest to the traffic characteristics of the target intersection can be automatically matched, and support is provided for signal optimization of the target intersection.

    本发明提供一种目标路口交通信号优化方法及系统。该目标路口交通信号优化方法包括以下步骤:S1.将已完成的案例路口信号优化方案根据路口问题进行分类,建立优化方案数据库;S2.根据目标路口的目标交通数据和优化方案数据库中各案例路口的参考交通数据,计算目标路口与各案例路口在同一路口问题上的相似度Si;S3.根据相似度Si确定目标路口的路口问题,并在将该路口问题中相似度最大值对应的案例路口作为目标路口的匹配路口;S4.提取该案例路口解决目标路口的路口问题的优化思路,进而输出目标路口的交通信号优化方案。本发明可以自动匹配与目标路口交通特性最相近的优化方案,为目标路口信号优化提供支撑。
