Problems solved by technology

[0004] The problem to be solved by the present invention is: the priority traffic of the BRT system is limited by the fixed time of the signal lights, and the expected efficiency cannot be reached. The existing signal priority control method has a great impact on the normal traffic of social vehicles at the intersection

Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] Such as figure 1 Shown is a flow chart of a pre-sensing signal priority control method for reducing operation delays at bus rapid transit (BRT) intersections, which will be further described in conjunction with examples below.

[0040] (1) Collect initial signal timing information, public transport facilities and operation information, and road facility information at each intersection of the road section;

[0041] In this step, the initial signal timing information of each intersection includes the signal phase number z of each intersection, the effective green light time and green light time interval of each phase, and the public transport facilities and operation information include the location of the first and last bus stop, the specific location of the bus stop, The number of bus stops M that the bus passes through on the road section, the departure sched...

Abstract

The invention relates to a crossing pre-induction signal priority control method used for a rapid bus. The method is applied to a bus rapid transit (BRT) system, multiple detectors are arranged at a crossing setting position, arrival time of a bus is predetermined in advance, length of a corresponding signal phase of a crossing is adjusted in proportion, and a signal lamp of the crossing is controlled. According to the invention, multiple detectors are arranged before the crossing under the premise of a bus rapid transit mode, the arrival time of the bus is predetermined in advance, the length of the corresponding signal phase is adjusted in proportion according to the actual passing priority requirement, public vehicles and pedestrian are guaranteed to pass safely, the bus can preferentially pass by fully utilizing a green light signal of the crossing, and operating efficiency of the bus is improved.

Description

technical field [0001] The invention belongs to the technical field of bus signal control, is used in a BRT system of a bus rapid transit, and is a priority control method for an intersection pre-sensing signal used in a bus rapid transit. Background technique [0002] As an integral part of the modern urban traffic system, urban public transport occupies a pivotal position in the urban traffic system. With the rapid development of social economy, people's demand for transportation is also increasing, and the trend of motorized travel is becoming more and more prominent. The resulting traffic problems such as urban traffic congestion have become the main bottleneck restricting the sustainable development of cities. Economical, safety and environmental aspects have caused significant losses. Prioritizing the development of urban public transport systems has become an important means to alleviate traffic problems including urban traffic congestion, traffic pollution, and peop...
