Urban road traffic bus priority signal control method

Abstract

The invention relates to a bus priority signal control method. The urban road traffic bus priority signal control method is that oriented reader-writers are installed at the crossroads, active electronic tags are installed in buses, and when the buses run close to the crossroads, the oriented reader-writers and the active electronic tags in buses act in cooperation with each other, interact with a traffic signal control system in a traffic command center and perform bus passing priority control by controlling traffic signal lamps at the crossroads: (1) green lamp time prolonging: when green lamps at the crossroads are about to change, the green lamp time in the advancing direction is prolonged to enable the buses about to arrive to pass the crossroads; (2) read lamp time breaking or calling for passing priority: after the current green lamp phase waits for the shortest green lamp time, existing red lamps are switched instantly for the buses arrived at a red lamp phase, bus priority green lamps are turned on in advance for bus passing. By adopting the urban road traffic bus priority signal control method, the bus operation speed can be effectively improved, the bus line travel time is reduced practically, and overall influence on other traffic flows is small.

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.
