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
The present invention relates to a kind of urban public transport signal control method, specifically, relate to a kind of public transport priority signal control method.
Background technology
Urban road is as the carrier of the magnitude of traffic flow, and its current conevying efficiency determines the choice for traveling of people to a great extent.Specify that in China's " national economy and social development the 12 five-year-plan outline " " implementing public transport priority strategy; greatly develop urban public tranlport system ", and propose " completed region of the city public transport all standing " to include national basic public services system in, first Public Transport Priority Development strategy is risen to national strategy.
Because public transit vehicle handling capacity of passengers is large, public vehicles handling capacity of passengers is little, and it is inappropriate for obviously putting two kinds of vehicles in identical status.The development that public traffic in priority is conducive to public transport is implemented in city, encourages citizen to take public transport trip, meets the developing direction of urban development and environment facies harmony.Because public traffic in priority can solve the trip problem of most people, simultaneously because public transit system is to the low occupation rate of resource, and the path resource that can reduce per capita occupies and discharges with decreasing pollution.
In view of the quickening of current urban development paces, public vehicles increase, and road construction is frequent, delay the current of public transit vehicle greatly, vast public transport participant are abandoned and takes city bus, cause the waste of resource.The construction of urban road simultaneously, cause crossing many, red light is many, and the vehicle stand-by period is long, also delays public transit vehicle greatly and passes through, and passenger is difficult to the travel time control.
In order to meet the requirement of safety, environmental protection, trip fast, the priority of public transit vehicle is improved, incuring loss through delay with the crossing reduced per capita in the stand-by period at crossing by reducing public transit vehicle, improving public transit vehicle efficiency of operation, meet the travel requirement of people, should be practicable.At present, about the research of this respect, person skilled is carrying out useful exploration always.
Summary of the invention
The present invention is directed to prior art Problems existing, propose a kind of urban highway traffic public transport priority signal control method based on vehicle GPS, effectively will improve mass transportation facilities overall trip speed and path resource utilization factor.
