Bus signal priority control method based on RFID vehicle-mounted electronic label

Abstract

The invention relates to a bus signal priority control method based on an RFID vehicle-mounted electronic label. The RFID electronic label is a taken as an information intermediary, and a bidirectional communication between public transport vehicles and a crossing control layer can be established; through guiding the public transport vehicles to reach and pass across a crossing appropriately, the road section travel speed of the bus is changed from priority model input to model output, and a signal control system is converted from adapting to the arrival of a traffic flow passively to guiding the traffic flow to arrive at and pass across the crossing, thereby giving full play to the efficiency of a control model and realizing maximization of system benefit; considering from the aspect of controlling the crossing control layer of the system, signal timing plan, suggested speed, station lingering time and other control parameters and the like core jobs are calculated, and a priority control scheme can be carried out through the communication with the RFID electronic labels, so that efficiency of processing priority algorithm of the crossing control layer can be improved, average vehicle delay and average parking frequency of the public transport vehicles are reduced to the maximum degree, and green time utilization rate is improved.

Description

technical field [0001] The invention relates to a traffic signal control technology, in particular to a bus signal priority control method based on RFID vehicle electronic tags. Background technique [0002] Bus signal priority is the main means to solve problems such as urban traffic congestion, and its realization is based on the information provided by bus detection technology. The coil detection technology and GPS detection technology are widely used in the existing bus priority schemes, but in the actual application process, there are still some shortcomings, mainly reflected in: 1) The coil detection technology only detects the bus on a fixed section of the road. 2) In the actual application of GPS technology, after obtaining vehicle information, it cannot exchange information with intersection units in real time, which lacks flexibility and increases the complexity of the center priority algorithm. In addition, in the case of scarcity of road resources, how to assign...
