The invention discloses a main and secondary trunk road intersection signal lamp timing intelligent control device and method. The device comprises monitoring roadside equipment, a geomagnetic detection coil, signal lamps and main and secondary trunk road signal lamp intelligent timing controllers. A geomagnetic coil, a millimeter-wave radar and an infrared detection sensor are used for monitoringqueuing waiting conditions and arrival conditions of motor vehicles and non-motor vehicles at all entrances of an intersection in real time, and a data basis is provided for a semaphore controller tocarry out trunk road priority control; priority passing of a main trunk road is considered, meanwhile, motor vehicle and non-motor vehicle passing requirements of a secondary trunk road are considered, the priority passing right of vehicles and pedestrians on the main trunk road can be guaranteed through a control program while the passing right of vehicles and pedestrians on the secondary trunkroad is guaranteed, and under the condition that no vehicle and no person pass within the green light duration of the secondary trunk road, the green light duration of the secondary trunk road can beautomatically distributed to the green light duration of the main trunk road, waste of the green light duration of the secondary trunk road is avoided, and the intersection of the main trunk road andthe secondary trunk road can have high intelligence.
本发明公开了一种主、次干道交叉口信号灯配时智能控制装置及方法,包括监控路侧设备、地磁检测线圈、信号灯和主、次干道信号灯智能配时控制器;利用地磁线圈、毫米波雷达和红外探测传感器实时监测交叉口各进口处的机动车和非机动车的排队等待情况和到达情况,为信号机控制器进行主干道优先控制提供了数据基础;考虑了主干道的优先通行,同时兼顾了次干道的机动车辆和非机动车辆通行要求,能够在保证次干道车辆和行人通行权的同时,利用控制程序保证主干道车辆和行人的优先通行权,在次干道绿灯时长内无车无人通行的情况下,可把次干道绿灯时长自动分配至主干道绿灯时长,避免了次干道绿灯时长的浪费,能够使得主/次干道交叉口具有较高的智能性。
