Abstract
A novel traffic light system capable of improving traffic efficiency of an intersection of a main road and a secondary main road comprises a master controller, infrared sensing devices and traffic lights. The master controller is used for controlling the displayable time of each green light on the main road to be 24+12N seconds and the displayable time of each green light on the secondary main road to be B seconds. Within the earlier 24-second time length, if the corresponding sensing devices detect objects waiting for crossing in sensing areas on the secondary main road, the green lights on the secondary main road are delayed to be turned on by a first 12-second time length after the earlier 24-second time is up; if the sensing devices detect the objects within the first 12-second time length, the green lights on the secondary main road are delayed by a second 12-second time length to be turned on, the green lights on the secondary main road are delayed by a fourth 12-second time length to be turned on if the objects are detected within a third 12-second time length, and the rest can be deduced in the same manner; and the maximum delay time for the green lights on the main road is 96 seconds which is the product of 6 times the sum of 12 seconds and 24 seconds if waiting objects are not detected on the secondary main road, then the green lights on the secondary main road are turned on and keep luminous for B seconds. The novel traffic light system has the advantages that vehicles do not need to wait around on the main road unnecessarily, energy is saved, and psychology of drivers is adjusted. The novel traffic light system is particularly applicable to intersections of main roads and secondary main roads which are quite different from one another.
