Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings.

[0047] like figure 1 Shown is a flow chart of the green wave control method between stations at a high-density intersection of main line public transport of the present invention:

[0048] 1) Determine the division and numbering of signal light groups according to the location of bus stops and intersections, and measure the distance between structures such as bus stops and intersections.

[0049] 11) Determination of signal lamp group. Set up all intersection signals between adjacent transit stops on an arterial as a signal group. The whole trunk line starts from the initial bus stop where the bus green wave is set, and ends at the end bus stop where the bus green wave is set, and the signal light groups and bus stops are respectively numbered. The number of the signal light group at the i-th position is D i , the i-th bus stop number is S i . Define the directio...

Abstract

The invention discloses an interstation green wave control method of high-density intersections of arterial buses. The method solves the problem that bus vehicles need to repeatedly stop for waiting red lamps when the gaps of the intersections in an urban trunk road are close is solved through the cooperative control of bus green waves among bus stations. The method comprises the following steps of determining the signal lamp group division and marking the number, presetting bus two-way green waves in a signal lamp group, judging passing request of bus vehicles, dividing bus green wave motorcades, and determining the bus vehicle speed induction and the early starting duration of the signal lamp group. The method has the advantages that the design is simple and convenient, the calculation is easy, after the bus vehicles are provided with interstation green wave control, the operation speed is greatly accelerated, the bus stop delay is reduced, and meanwhile, the pollutant discharging and the energy consumption are also greatly reduced.

Description

technical field [0001] The invention belongs to the field of traffic management and control, relates to urban public transport planning and intersection signal control technology, and relates to a green wave control method between stations at high-density intersections of trunk lines. Background technique [0002] Due to the travel needs of residents, the road network density in some areas is relatively high during the planning of urban arterial lines, resulting in the close spacing of intersections in many urban areas, with an average spacing of 100 meters or even closer. These continuous intersections are called high-density intersections. At present, the control between signal lights at many high-density intersections is mostly offline and discrete, and linkage control has not been realized. This causes vehicles to frequently accelerate and decelerate and wait for red lights when passing through the intersection, and the delay is greatly increased. [0003] As an integra...
