Traffic lights factory suggest we have a what kind of signal control methods
1. Punctuality control
Intersection traffic signal control machine are set in advance the timing plan, also known as fixed cycle control. One day only a timing plan known as the single sections of punctuality control; Day at different times of the traffic flow to choose a few known as many sections of punctuality control timing plans. The most fundamental control method is punctuality control of single intersection. Line control, plane control are also available punctuality control method, also called static line control system, the static surface controlling system.
2. The induction control
Induction control is imported in the intersection set vehicle detector, traffic signal timing plans business accounting, accounting machine or intelligent signal control machine can change at any time with the detector detects the traffic information and a control method. Induction control single intersection is the basic method of induction control, hereinafter referred to as a single point of control induction manipulation. Single point induction control method with the detector set of different can be divided into half induction control and induction control.
