The invention provides a traffic signal period duration dynamic adjustment method based on trajectory data. The method comprises the following steps: step 1, determining a data source; step 2, data integration and standardization; 3, traffic flow characteristics are extracted; and 4, constructing a dynamic traffic model, and dynamically adjusting the period duration of the traffic signal. According to the method, the traffic flow efficiency can be improved, the traffic flow change can be more accurately predicted by utilizing real-time data analysis, and the signal period can be dynamically adjusted, so that the vehicle waiting time is shortened, and the overall road traffic capacity is improved. According to the method, big data analysis and an artificial intelligence algorithm are combined, automation and intelligence of traffic signal control are achieved, and dependence on manual intervention is reduced.

    本发明提供了一种基于轨迹数据的交通信号周期时长动态调整方法,包括以下步骤:步骤1,确定数据源;步骤2,数据集成与标准化;步骤3,提取交通流量特征;步骤4,构建动态交通模型,对交通信号周期时长进行动态调整。本发明方法能够提高交通流效率:利用实时数据分析,本方法能够更精确地预测交通流量变化,动态调整信号周期,从而减少车辆等待时间,提升整体道路通行能力。本发明方法结合大数据分析和人工智能算法,本方法实现了交通信号控制的自动化和智能化,减少了对人工干预的依赖。
