Public transport priority signal real-time control method based on RFID and terrestrial magnetism detection

Abstract

The invention discloses a public transport priority signal real-time control method based on an RFID and terrestrial magnetism detection, and the method comprises the steps: reading the information of an RFID electronic tag on a vehicle through employing an RFID reader, and employing a terrestrial magnetism vehicle detector to detect the information of a passing vehicle; enabling the RFID reader and the terrestrial magnetism vehicle detector to transmit the collected information to data collection processing equipment, and enabling the data collection processing equipment to transmit the processed information to a traffic information phase control equipment, and controlling the signal lamp to carry out the prior allowing or stop the prior allowing through the traffic signal phase control equipment. The method does not need to manually set the time duration of prior allowing, and prevents the unreasonable setting and the running speed differences of vehicles from causing phase useless allowing or the insufficient allowing time. The method effectively reduces the impact on the social vehicles from the prior buses, and improves the traffic efficiency of intersections.

Description

technical field [0001] The invention relates to the field of traffic signal control, in particular to a real-time control method of bus priority signals based on RFID and geomagnetic detection. Background technique [0002] The use of bus priority signal control is a reasonable and effective measure to improve the quality and effectiveness of bus operations, fully embodying the idea of ​​bus priority, especially after giving priority to buses with high passenger capacity, it can reduce the per capita delay at intersections and improve intersection services Level, to provide conditions for the bus to attract more passenger flow. Reasonable bus priority signal timing can reduce vehicle delays. However, after the existing RFID-based bus priority control system detects the passing of the priority vehicle, it gives the priority vehicle the right of passage for a fixed time according to manual settings, and the priority release time is set entirely based on experience. As a resu...
