Problems solved by technology

[0004] Another factor hindering the promotion of the "green wave belt" technology is that once the green wave vehicle is disturbed, it is likely to miss the green wave passing time of the "green wave belt", because the green wave vehicle cannot grasp the "green wave belt" when driving in the road section. "Related information, I only know that you must drive at the speed of the green wave to stay in the "green wave zone". Once you are delay

Embodiment 1

[0058] Such as figure 1 As shown on an east-west main road, a 400-meter-long road section between two intersections from west to east is selected as the research object, then the intersection on the west side of the road section is the entrance intersection, and the intersection on the east side of the road section The mouth is an exit intersection. Set up subsection signal light 1 at 50 meters from the exit stop line, and a 50-meter long section between it and the exit stop line is subsection 1; set up subsection signal light 2 at 150 meters from the exit stop line, which is connected to the exit stop line A 100-meter-long road section between sub-section signal lights 1 is sub-section 2; a sub-section signal light 3 is set up at a distance of 250 meters from the exit stop line, and a 100-meter-long road section between it and sub-section signal lights 2 is Sub-section 3; Finally, a sub-section signal light 4 is set up at 350 meters away from the exit stop line, and a 100-me...

Embodiment 2

[0076] This embodiment discusses whether the coordinated control method described in the present invention can also ensure that green-wave vehicles can run in the "green-wave belt" under complex road conditions.

[0077] image 3 The road segment shown in is figure 1 The planar view of the real-time road conditions of the middle road section at t=100 seconds, the difference is that there is an extra fork in the sub-road section 2, and there is a pedestrian 25 crossing the road on the sub-road section 3 at this moment, he will interfere F car, G car normal driving.

[0078] Due to the increase of factors that interfere with the normal driving of green wave vehicles at forks, the speed of green waves on sub-section 2 should be appropriately reduced to reduce the impact of interference factors. Specific measures are as Figure 4 As shown, adjust the phase difference between the signal timing scheme of sub-section signal light 2 and sub-section signal light 1 to O 2 =15 second...

Embodiment 3

[0082] This embodiment illustrates how the coordination control method described in the present invention is combined with the adaptive signal control system to improve its performance. Specifically, how the signal lights of each sub-section change its signal timing scheme in real time according to the real-time traffic conditions collected by the vehicle detector, and how this real-time change has a real-time impact on the driving of green wave vehicles.

[0083] Such as figure 1As shown, when the vehicle detector 7 detects that the vehicle A passes by, no other vehicles are detected within the set time period of 8 seconds, and the computer adjusts all sub-section signal lights and exit intersections in real time according to this situation. The signal timing scheme of port signal lights. Such as Image 6 As shown, the end time of signal phase 1 of each sub-section signal light is advanced by 4 seconds, and the start time of signal phase 2 of each sub-section signal light i...

Abstract

The invention relates to a method for coordinately controlling sub road section green wave induction and distribution, which belongs to the field of road traffic signal control. The method comprises steps: a set of traffic signal lights are installed on a road section every 100m along any driving direction between two road crossings, and then, the signal lights within the road sections and the signal lights at an exit are commonly and coordinately controlled; the distances among all the signal lights within the road sections are greatly reduced relative to the distances among all the road crossings, and accordingly, the relevant information of 'a green wave band' which can only and originally be observed from the position around a crossing can be obtained at any position within the road section. When the vehicle just travels on the road section or is interfered, a driver can still figure out whether himself is in or out the 'green wave band', thus deciding to adjust the speed for driving into the 'green wave band'. Consequently, the 'green wave band' is only correlative with the signal lights at the exit, and the united coordination control of the signal lights of all the road crossings on the same road is not needed to be performed as in the existing 'green wave band'.

Description

technical field [0001] The invention relates to the field of road traffic signal control, in particular to a method for implementing green wave coordinated control to induce shunting vehicles in a road section between two intersections. Background technique [0002] Generally speaking, the present invention belongs to a new type of "green wave band" technology. The so-called "green wave belt" is actually a figurative term for "multi-point coordinated control technology of signal lights", that is, to implement unified coordinated control of signal lights in an area or on a road, and to link all signal lights included in the control range. The signal timing scheme of each signal light is coordinated and controlled, so that when the traffic flow is driving on the arterial road, it encounters green lights one after another at each intersection, and passes through all intersections along the way unimpeded. From the perspective of the driver, the green light in front looks like g...
