The invention relates to the technical field of traffic guidance, in particular to a traffic signal lamp control method and system for a smart city. The method comprises the following steps: obtaininga road segment image of a road where a vehicle commanded by a traffic signal lamp is located in real time; the method is characterized by including the steps of judging whether vehicles are parked ona road according to road section images; if the parked vehicle exists on the road, identifying a lane where the parked vehicle is located and an adjacent lane according to the road section images; according to the road section images, the lane where the vehicle is located and the adjacent lane, judging whether traffic jam occurs in the lane where the parked vehicle is located; if the lane where the parked vehicle is located is subjected to traffic jam, generating a signal lamp regulation and control instruction; and adjusting the timing scheme of a traffic signal lamp according to the signallamp regulation and control instruction, and controlling the turn-on duration of the green light of the traffic signal lamp according to the adjusted timing scheme. By adopting the scheme, the technical problem that the traffic jam condition of each lane cannot be effectively monitored in the prior art can be solved.

    本发明涉及交通引导的技术领域,具体为一种用于智慧城市的交通信号灯控制方法及系统,该方法包括以下步骤:实时获取交通信号灯所指挥车辆所在道路的路段图像;其特征在于:根据路段图像判断道路上是否有停放车辆;若道路上存在停放车辆时,则根据路段图像识别停放车辆的所在车道和相邻车道;根据路段图像、所在车道和相邻车道判断停放车辆的所在车道是否发生交通拥堵;若停放车辆的所在车道发生交通拥堵时,则生成信号灯调控指令;根据信号灯调控指令调节交通信号灯的配时方案,根据调节后的配时方案控制交通信号灯绿灯的开启时长。采用本方案能够解决现有技术中无法有效监测每一车道的交通拥堵情况的技术问题。
