The invention relates to road signal lamp control, in particular to a signal coordination control method for an urban expressway exit ramp and a connection intersection, which comprises the following steps: acquiring detection data of an upstream detector and a downstream detector of an entrance lane of the connection intersection and detection data of an upstream detector and a downstream detector of the exit ramp; judging whether the connection intersection and the exit ramp are in a congestion state or not; when the connection intersection is congested and the exit ramp is not congested, a congestion signal timing scheme is started for the connection intersection, and a signal lamp of the exit ramp is set to be red; when the connection intersection is not congested and the exit ramp is congested, starting a coordination control strategy of the exit ramp and the connection intersection; when the connection intersection is congested and the exit ramp is congested, a congestion signal timing scheme is started for the connection intersection, and a signal lamp of the exit ramp is set to be red; according to the technical scheme provided by the invention, the defect that the influence of the urban expressway exit ramp on the ground road traffic cannot be effectively reduced in the prior art can be overcome.
本发明涉及道路信号灯控制,具体涉及城市快速路出口匝道与衔接交叉口的信号协调控制方法,获取衔接交叉口进口道的上游检测器、下游检测器,以及出口匝道的上游检测器、下游检测器的检测数据,并判断衔接交叉口及出口匝道是否处于拥堵状态;当衔接交叉口拥堵,出口匝道不拥堵,则对衔接交叉口启动拥堵信号配时方案,并将出口匝道的信号灯设置为红灯;当衔接交叉口不拥堵,出口匝道拥堵,则启动出口匝道与衔接交叉口的协调控制策略;当衔接交叉口拥堵,出口匝道拥堵,则对衔接交叉口启动拥堵信号配时方案,并将出口匝道的信号灯设置为红灯;本发明提供的技术方案能够克服现有技术所存在的不能有效减小城市快速路出口匝道对地面道路交通影响的缺陷。
