A system for optimizing traffic light timing using telemetry includes a wireless connected device (WCD), a traffic center of operation (TOC) that controls one or more traffic lights, and a control module that stores and continuously executes control logic in a closed loop. The control logic continuously receives real-time WCD telemetry data and processes the telemetry data in real time to match the telemetry data to a physical location. The processed telemetry data is aggregated to determine a trajectory of the WCD. The system selectively performs time of day (TOD), offset, and green light segmentation optimization, and receives a trajectory of the WCD and outputs of the TOD, offset, and green light segmentation optimization within the API. The system generates an optimized signal scheme from the data of the API and verifies the optimized signal scheme. The TOC receives the optimized signal scheme and selectively uploads the optimized signal scheme to the traffic lights. The optimized signal scheme improves traffic throughput by reducing total delay and number of stops.

    一种使用遥测技术优化交通信号灯配时的系统,包括:无线连接设备(WCD)、控制一个或多个交通信号灯的交通运营中心(TOC)以及在闭环中存储并连续执行控制逻辑的控制模块。控制逻辑连续接收实时WCD遥测数据,并对遥测数据进行实时处理,以将遥测数据与物理位置相匹配。聚合处理后的遥测数据以确定WCD的轨迹。该系统选择性地执行当日时间(TOD)、偏移量和绿灯分段优化,并在API内接收WCD的轨迹以及TOD、偏移量和绿灯分段优化的输出。该系统根据API的数据生成优化信号方案,并验证优化信号方案。TOC接收优化信号方案并选择性地上传至交通信号灯。优化信号方案通过减少总延误和停车次数来提高交通吞吐量。
