Abstract: The present invention is a system and method for dynamically and accurately allocating green light time of a traffic light at a given intersection by counting the number of vehicles located in an approach to a given intersection. A signal controller radio transceiver of a stationary intersection mounted control unit (CU) receives identifying signals transmitted by the on board vehicle radio transceiver of vehicles located at an approach to this intersection. A signal controller interface processing unit of the CU at the given intersection is operable to disregard signals transmitted by vehicles located at one or more upstream intersections and by pedestrians and passengers of a common motor vehicle. The number of vehicles located at an approach is thereby counted, allowing the CU to dynamically allocate green light time of a corresponding traffic light in accordance with traffic arrangement, for example per approach or per signal group, and design preferences.

Abstract translation: 本发明是一种用于通过对位于给定交叉点的方法中的车辆的数量进行计数来动态地和准确地分配给定交叉口处的交通信号灯的绿灯时间的系统和方法。 固定交叉路口安装的控制单元（CU）的信号控制器无线电收发机接收位于该交叉点附近的车辆的车载无线电收发器发送的识别信号。 在给定交叉路口处的CU的信号控制器接口处理单元可操作以忽略位于一个或多个上游交叉口处的车辆以及普通机动车辆的行人和乘客所发送的信号。 因此，对于位于接近处的车辆数量进行计数，从而允许CU根据流量布置动态地分配对应的交通信号灯的绿灯时间，例如每个方向或每个信号组以及设计偏好。
