The invention discloses a calculation method for an abnormal release state of an entrance lane, and the method comprises the steps: calculating a stage-lane expectation correlation index of each lane, so as to form a stage-lane expectation correlation index vector, and constructing a stage-lane expectation correlation index matrix of an intersection; calculating a stage-lane actual association index of each lane to form a stage-lane actual association index vector, and constructing a stage-lane actual association index matrix of the intersection; and based on the stage-lane expectation association index matrix and the stage-lane actual association index matrix, calculating a correlation coefficient of a lane-stage expectation association index vector and a lane-stage actual association index vector of each lane, and analyzing whether an abnormal release state exists or not to obtain an abnormal release state result. According to the invention, automatic detection of conditions of lane association relationship disorder, lamp group wiring disorder and the like caused by lane association relationship configuration errors and system updating is realized, and the workload of manual parameter configuration verification is reduced.

    本发明公开了一种进口道异常放行状态的计算方法,包括:计算各车道的阶段‑车道期望关联指数,以形成阶段‑车道期望关联指数向量,构建路口的阶段‑车道期望关联指数矩阵;计算各车道的阶段‑车道实际关联指数,以形成阶段‑车道实际关联指数向量,构建路口的阶段‑车道实际关联指数矩阵;基于阶段‑车道期望关联指数矩阵和阶段‑车道实际关联指数矩阵,计算各车道的车道‑阶段期望关联指数向量与车道‑阶段实际关联指数向量的相关系数,分析是否存在异常放行状态,得到异常放行状态结果。本发明实现了车道关联关系配置错误、系统更新导致的车道关联关系错乱、灯组接线错乱等情况的自动检测,减轻了人工校验参数配置的工作量。
