Abstract

The invention provides a vehicle-mounted-GPS-based public transport priority signal control method of the urban road traffic. A vehicle-mounted GPS positioning system is installed at a bus. When the bus approaches an intersection, the vehicle-mounted GPS positioning system sends a verification data signal to a traffic command center; the traffic command center carries out communication with a front-end intersection signal machine and a traffic signal lamp at the intersection is controlled to be changed so as to realize public transport priority passing control. To be specific, (1), the green light time is prolonged; when the green light time at the intersection is coming to the end, the green light time at the marching direction is increased, so that the incoming bus can pass through the intersection; and (2), the red light time is interrupted or priority passing is called for; for the bus arriving at the red light phase, the existing red light is switched after the shortest green light time of the current red light phase and thus the bus priority green light is turned on in advance. Therefore, the bus operation speed is effectively accelerated; the bus route time is reduced practically; and the overall impact on other traffic flow is low.

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 ...
