A traffic control system is provided including an arrangement of traffic lights at a traffic intersection, and a radar sensor installed at the intersection such that its field and range of detection covers at least one approach to the intersection. The radar sensor is adapted to sense the presence of vehicles within a predetermined field of view and range. A controller for switching the traffic lights is operated by an electronic processor utilizing information developed from data inputted from the radar sensor. The radar sensor is a multi-object radar sensor capable of developing data from which the location, speed, acceleration or deceleration, and direction of travel of each vehicle within its field and range of detection can be derived.
