摘要： A traffic control system is provided including an arrangement of traffic lights (2) at a traffic intersection (1 ), and a radar sensor (5) installed at the intersection such that its field and range of detection (6) covers at least one approach to the intersection. The radar sensor (5) is adapted to sense the presence of vehicles within a predetermined field of view and range. A controller (8) for switching the traffic lights is operated by an electronic processor (7,11) utilising information developed from data inputted from the radar sensor (5). The radar sensor (5) 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. The operation of the traffic lights (2) is dependent, at least to some extent, on the number of vehicles (16) sensed within said field and range or the behavioural pattern of one or more vehicles within said field and range, or both. Preferably, a multi-object radar sensor (5) is provided for each approach to the intersection (1 ). The electronic processor may be programmed to provide an output on the basis of computational or artificial intelligence optionally in combination with one or more appropriate algorithms.
