The invention discloses a traffic flow-based traffic signal lamp intelligent control system and a traffic flow-based traffic signal lamp intelligent control method. The method comprises the following steps: firstly, arranging traffic flow data at a plurality of preset time points into traffic flow time sequence input vectors, and then carrying out local time sequence feature analysis to obtain a sequence of traffic flow local time sequence feature vectors; carrying out traffic flow time sequence fluctuation semantic measurement on every two adjacent traffic flow local time sequence feature vectors to obtain a traffic flow time sequence fluctuation semantic feature vector, then cascading sequences of the traffic flow local time sequence feature vectors to obtain a traffic flow full time domain semantic feature vector, and finally obtaining a traffic flow full time domain semantic feature vector; and processing the traffic flow full-time domain semantic feature vector and the traffic flow time sequence fluctuation semantic feature vector by using a projection layer to obtain a traffic flow time sequence multi-dimensional semantic feature, and finally, based on the traffic flow time sequence multi-dimensional semantic feature, determining a recommended signal lamp duration. Therefore, the traffic efficiency and the safety can be improved.

    公开了一种基于车流量的交通信号灯智能控制系统及方法。其首先将多个预定时间点的车流量数据排列为车流量时序输入向量后进行局部时序特征分析以得到车流量局部时序特征向量的序列,接着,对每相邻两个车流量局部时序特征向量进行车流量时序波动语义度量以得到车流量时序波动语义特征向量,然后,将所述车流量局部时序特征向量的序列进行级联以得到车流量全时域语义特征向量,接着,使用投影层对所述车流量全时域语义特征向量和所述车流量时序波动语义特征向量进行处理以得到车流量时序多维度语义特征,最后,基于所述车流量时序多维度语义特征,确定推荐的信号灯时长。这样,可以提高交通效率和安全性。
