An intelligent traffic command system and its control method

Abstract

The invention discloses an intelligentized traffic command system and a control method thereof, comprising an electronic license plate, RFID readers, a controller and a traffic lamp; the electronic license plate is installed on the automobile; the electronic license plate comprises an RFID chip; the RFID reader is connected to the controller; the RFID chip stores the identification code of the automobile; the quantity of the RFID readers is plural and the RFID readers are installed on the side of the lane; the controller is connected to the traffic light; each lane corresponds to the plurality of RFID readers which read the identification code in the electronic license plate so as to know the queuing vehicles in various lanes; the controller regulates the time interval of switching the traffic lamp according to the quantity of the queuing vehicles; when the queuing vehicles in a lane is greatly more than the vehicles in the other lanes, the time duration of the green light is extended; and when the queuing vehicles in a lane is greatly less than the vehicles in the other lanes, the tine duration of the green light for this lane is shortened. The scheme is applicable to the crossing having the traffic light.

Description

technical field [0001] The invention relates to traffic command settings, in particular to an intelligent traffic command system and a control method thereof. Background technique [0002] With the gradual increase of car ownership, urban traffic pressure is increasing, and travel is becoming more and more congested. How to effectively control the traffic flow to obtain the highest traffic operation efficiency is a subject of continuous research by relevant departments. [0003] Traffic light is an important tool to guide traffic flow, which consists of red light, green light and yellow light. A red light means no access, a green light means permission to pass, and a yellow light means a warning. [0004] The State Intellectual Property Office of the People's Republic of China published a patent document titled "Single-chip Microcomputer-Based Traffic Light Control System" on April 29, 2015 (publication number: CN104575028A), which includes a single-chip microcomputer cont...
