What are the modes of control for traffic lights?
There are several control signals of traffic lights which are regularly controlled: the traffic signal control units of intersections are operated according to the preset timing scheme, also known as fixed cycle control.
Line control, surface control are also available timing control, also known as static wire by wire system, static surface control system.
control induction: induction control is set at the intersection of imported vehicle detector on the road, the traffic signal timing scheme is calculated by computer or intelligent signal controller, a control method with the detected traffic information at any time to change
, the traffic adaptive control system as an uncertain system can continuously measure the state, such as traffic flow, parking time, delay time, queue length, gradually understand and grasp the object
