Problems solved by technology

Under such signal control conditions, although the traffic efficiency of priority vehicles can be significantly improved, the traffic efficiency of non-priority vehicles is often seriously affected, and it may even cause overflow of queuing vehicles at intersections or disorder of intersection operations.
Therefore, the traditional signal priority control method cannot effectively guarantee the effective improvement of the traffic efficiency of BRT vehicles on the premise that the normal operation of the intersection is less affected

Embodiment

[0067] Example: see figure 1 with figure 2 , the present invention includes the following steps,

[0068] Step 1: collect basic data of BRT lines, road intersections, road traffic flow, and real-time AVL data of BRT vehicles.

[0069] In this step, the BRT line information includes line direction, station location, operation and scheduling plan; road intersection information includes intersection signal control plan, intersection channel planning design plan; road traffic flow includes various types of traffic in different flow directions at the intersection Traffic: Real-time AVL data of BRT vehicles includes real-time position and time information of BRT vehicles.

[0070] In this example, the line direction, station location, operation and dispatch plan can be obtained from the public transport company; the intersection signal control plan and the intersection canal planning design plan can be obtained through field surveys; the various types of traffic flow in different...

Abstract

The invention discloses a prior control method for a bus rapid transit signal during traffic mean peak duration. According to bus rapid transit vehicle operation characteristics, moments of reaching intersections of bus rapid transit vehicles and traffic requirements of non-prior motor vehicles, pedestrians and non-motor vehicles, the bus rapid transit vehicles pass through the intersections in a priority manner on the basis of dividing an intersection signal period into six sections by adjusting green light time of bus rapid transit phases.

Description

technical field [0001] The invention relates to a technology for priority control of urban express public transport signals, in particular to a method for priority control of express public transport signals during a traffic flat-peak period. Background technique [0002] BRT is a new type of urban public transportation with high quality, low cost, flexibility, convenience, speed and comfort. It is between rail transit and conventional buses, and can achieve the service level of rail transit through technologies such as modern station setting, exclusive right of way protection, and priority control of intersection signals. [0003] There are many traditional signal priority control methods at intersections. Signal control strategies such as early activation of priority phases, extension of priority phases, insertion of priority phases, and phase inversion are usually used to provide priority traffic signals for vehicles that need to travel in priority. The above signal cont...
