The invention provides an intersection traffic flow state identification method and traffic signal control equipment, and relates to the technical field of intelligent traffic. For each traffic flow steering at the target intersection, the actual saturation of the traffic flow steering in the current signal control period is calculated according to the maximum saturation flow rate of the traffic flow steering and the actual signal control traffic data of the traffic flow steering in the current signal control period; and calculating an actual traffic flow state score of the traffic flow steering in the current signal control period by combining a historical traffic flow state score of the traffic flow steering in a previous signal control period of the current signal control period according to a target traffic flow state scoring rule adapted to the target intersection, and performing traffic flow state identification. Therefore, the influence of the traffic flow volatility in the intersection traffic flow state identification process is deeply considered, and the final traffic flow state identification result is ensured to accurately reflect the overall change trend of the real intersection traffic flow state in the time dimension level.
本申请提供一种路口交通流状态识别方法及交通信号控制设备,涉及智能交通技术领域。本申请针对目标路口处的每种车流转向,会根据该种车流转向的最大饱和流率及该种车流转向在当前信控周期的实际信控交通数据,计算该种车流转向在当前信控周期的实际饱和度,并结合该种车流转向在当前信控周期的上一信控周期的历史交通流状态得分,按照与该目标路口适配的目标交通流状态评分规则,计算该种车流转向在当前信控周期的实际交通流状态得分进行交通流状态识别,从而深度考虑交通流波动性在路口交通流状态识别过程中的影响,确保最终的交通流状态识别结果可以精准反映真实路口交通流状态在时间维度层面的整体变化趋势。
