The embodiment of the invention provides a traffic control system and method. The traffic control system may include a communication interface (310) configured to receive vehicle trajectory data (302)acquired by a sensor and traffic control data (304) from a traffic signal controller (106). The traffic control system may also include at least one processor (320). The at least one processor (320)may be configured to detect an abnormal traffic condition. The at least one processor (320) may be further configured to optimize an online traffic control scheme by adjusting a green signal ratio ofthe at least two phases based on the vehicle trajectory data (302). The at least one processor may also be configured to provide the optimized online traffic control scheme to a traffic signal controller (106) in real time to generate a traffic control signal.
本申请的实施例提供了交通控制系统和方法。该交通控制系统可以包括通信接口(310),该通信接口被配置为接收由传感器获取的车辆轨迹数据(302)和来自交通信号控制器(106)的交通控制数据(304)。该交通控制系统还可包括至少一个处理器(320)。该至少一个处理器(320)可以被配置为检测异常交通状况。该至少一个处理器(320)可以进一步被配置为基于车辆轨迹数据(302),通过调整至少两个相位的绿信比来优化在线交通控制方案。该至少一个处理器还可以被配置为实时地将优化的在线交通控制方案提供给交通信号控制器(106)以产生交通控制信号。
