Crossing traffic control system and method

Abstract

The invention discloses a crossing traffic control system, comprising a plurality of signal lamps and a first vehicle detector arranged on each lane stop line in each direction of the crossing as well as a controller, a second vehicle detector arranged at the preset distance after each lane stop line in each direction of the crossing and a monitoring host arranged at far end; wherein the output terminals of the first vehicle detector and the second vehicle detector are connected with the input terminal of the controller, the output terminal of the controller is connected with the signal lamps; and the controller is connected with an optical fiber optical transceiver and carries out fiber optical communication with the monitoring host. The invention also discloses a crossing traffic control method, the controller controls the change of signal lamps by monitoring signal of each vehicle detector. The invention can cause vehicles to be all the way unimpeded at the crossing with less traffic flow, waiting time is saved, and meanwhile special vehicle preferentially passes, and violation of regulation conditions, such as lane changing under violation of regulation and disguised red light running, can be effectively detected and reported, and traffic accident is reduced.

Description

technical field [0001] The invention relates to a traffic control system of road vehicles, in particular to a crossing traffic control system and a control method suitable for remote suburbs. Background technique [0002] With the acceleration of urbanization and motorization in the world, urban traffic is becoming a global problem, and traffic accidents occur frequently. There are some unreasonable and functional deficiencies in the existing traffic control system: [0003] 1. For the suburbs, the traffic flow is less, and sometimes there will be cars waiting on a road with a red light, but there will be no cars passing on the road with a green light. Phenomenon, laying hidden dangers to the occurrence of traffic accidents; [0004] 2. If special vehicles such as police cars and medical vehicles need to pass through the intersection urgently, the existing traffic control system is helpless, and can only be achieved by other vehicles actively avoiding and special vehicles ...
