Urban road traffic bus priority signal control method

Abstract

The invention relates to a bus priority signal control method. A method for controlling public priority signals in urban road traffic. A directional reader is installed at the intersection, and an active electronic tag is installed on the bus. When the bus approaches the intersection, the directional reader corresponds to the active electronic tag on the vehicle. And interact with the traffic signal control system of the traffic command center, by controlling the change of the traffic signal lights at the intersection, the priority traffic control of the bus is carried out: 1) Extend the green light time: when the green light at the intersection is about to end, extend the green light time of the traveling direction to make the arrival 2) Cutting off the red light time or calling for priority traffic: For buses arriving at the red light phase, after the current green light phase passes the shortest green light time, the existing red light will be switched immediately, and the priority green light of the bus will be turned on in advance for convenience. bus traffic. The invention can effectively increase the operating speed of public transport vehicles, effectively reduce the travel time of public lines, and has little overall impact on other traffic flows.

Description

technical field [0001] The invention relates to a method for controlling urban public traffic signals, in particular to a method for controlling public traffic priority signals. Background technique [0002] Urban roads are the carriers of traffic flow, and their transportation efficiency largely determines people's travel choices. my country's "Outline of the Twelfth Five-Year Plan for National Economic and Social Development" clarifies "implementing the strategy of giving priority to the development of public transportation and vigorously developing the urban public transportation system", and proposes to incorporate "full coverage of public transportation in urban built-up areas" into the national basic In the public service system, for the first time, the public transport priority development strategy has been upgraded to a national strategy. [0003] Due to the large passenger capacity of public transport vehicles and the small passenger capacity of social vehicles, it ...

AI Technical Summary

Problems solved by technology

[0004] In view of the acceleration of urban development, the increase of social vehicles and frequent road construction, the passage of public transport vehicles has been greatly delayed, and the majority of public transport participants have given up taking urban public transport, resulting in a waste of resources

At the same time, the construction of urban roads has resulted in many intersections, many red lights, and long waiting times for vehicles, which also greatly delays the passage of buses, and it is difficult to control the travel time of passengers.
