Urban traffic signal control scheme recommendation method, system, device and medium

The invention relates to an urban traffic signal control scheme recommendation method, system and device and a medium, and the method comprises the steps: obtaining the traffic state index of an intersection according to the relative traffic state of the intersection, a traffic state extreme value identifier and a dynamic coefficient, and enabling the traffic state index to be used for evaluating the operation condition of the intersection, under the condition that the traffic state index is larger than a preset threshold value, an intersection signal control scheme is recommended for the intersection through a pre-trained intersection depth recommendation model, and the intersection signal control scheme comprises a combination of a signal period length and a phase green signal ratio. The problems of high labor cost and low efficiency in the prior art are solved, and the problem of traffic jam is effectively solved. 本申请涉及一种城市交通信号控制方案推荐方法、系统、装置和介质，通过根据交叉口的相对交通状态、交通状态极值标识和动态系数，获取交叉口的交通状态指标，其中，交通状态指标用于评估交叉口的运行情
