Problems solved by technology

[0003] In European and American countries, due to the small demand for bicycles and pedestrians to cross the street, and right-turning motor vehicles need to stop and give way, there are few literatures on right-turning traffic flow signal control
However, domestic attention to this issue is not enough, leading to frequent accidents in the process of right-turning motor vehicles, non-motor vehicles, and pedestrians competing for the right of way

Embodiment

[0110] The example of this embodiment is controlled by a special lane control of a certain intersection in Shanghai. It collects basic materials such as the canal design scheme and control scheme of the cross port, and conduct a peak -hour traffic survey.The time of the four phase green lights is 75S, 25S, 60S, 48S, and the cycle is 220s.Taking the imported road in this embodiment as an example, the right transfer Q Quan Q Q Q Q q PHF = 466pcu / h.It should be noted that this embodiment is implemented under the premise of the technical solution of the present invention, and a detailed implementation method and specific operation process are given, but the protection scope of the present invention is not limited to the following examples.

Abstract

The invention relates to a signal crossing right turn special lane real-time dynamic control method, and is aimed at solving a domestic civic crossing right turn special lane signal control dynamic time determination problem. The method comprises the following steps: (1) predicating arrived right turn motor vehicle, non-motor vehicle and pedestrian flow in present period; (2) calculating a corresponding basic control time when integration cost is minimal; (3) executing a right turn red light signal according to right turn basic control time; (4) dynamically detecting agglomeration degree magnitude in a conflict zone; (5) determining whether prolonging right turn control time is needed or not, and if so, prolonging the right turn control time, otherwise releasing the right turn red light signal if the right turn control time is up. According to the method, practical pass demands of a non-motor vehicle, a pedestrian and a right turn motor vehicle are considered synthetically, delay of each traffic flow passing a crossing is reduced, and conflict minimization of each traffic participant is ensured. While ensuring security of the non-motor vehicle and the pedestrian in a conflict direction, passing efficiency of the right turn motor vehicle is raised.

Description

Technical field [0001] The present invention involves a method for the field of signal control in urban cross-port. More specifically, the invention involves a real-time dynamic control method based on a traffic-agglomeration-based signal intersection.Application innovation. Background technique [0002] Cross -port signal control is the core means to improve the safety and efficiency of the cross section.At present, when formulating a traffic control plan, people often pay more attention to direct and left -turn traffic integrated, and for right transfer traffic flows, they often do not control signal control.The reason is that in accordance with the "Road Traffic Safety Law": "When motor vehicles pass through the cross travelers, they should slow down; those who are passing through the pedestrian crossway should stop for a parking."But in fact, according to statistics, less than one -third of the right transfer will actively allow non -motorized vehicles and pedestrians.At the ...
