String super-mode control method for traffic signals

Abstract

The invention relates to the field of traffic signal modes, and discloses a super signal mode control method for traffic signals, namely, a string super-mode. The method mainly comprises the steps of1) obtaining a string super-mode type mode instruction; 2) setting basic parameters such as partition network nodes and reconfiguration period of the string super-mode; 3) configuring a string super-mode structure of two-dimensional green waves of related areas; 4) calculating the time difference and configuration transition period of the two-dimensional green waves; and 5) running a switching transition period before executing a new cycle. The method realizes signal effect equalization, high efficiency, multiple purposes, universality and convenience. The traffic flow can go to all positionsof a string super-mode wormhole type control area from any direction with the average consumption being less than 3.5 times of red light waiting, and the traffic flow of a congestion evacuating inletarea and a congestion evacuating outlet area can be quickly taken in or out in an omnidirectional manner based on various variants thereof no matter how many intersections there are, thereby assistingthe trunk road to divert the traffic in the same flow direction, and carrying out fast away flow guidance in the crossing direction at the same time. The invention further provides an omnidirectionala pulsar mode capable of running across the whole area with one green wave and reaching any position with one red light. The number of parameters determining the super-mode is about 20, and the switching is fast and redundant-free, so that a plane type traffic control, foundation analysis and control module is provided for urban traffic control.

Description

technical field [0001] The invention relates to the technical field of traffic signal control. Specifically, a chordal hypermodal control method for traffic signals. Background technique [0002] At present, urban traffic signal control, including regional control, is mainly based on arterial coordinated control technology, prioritizing the optimization of arterial roads and balancing non-arterial roads, which is the result of the interaction between cities and the development and evolution of traffic control technology. The linear green wave of the arterial road can make "traffic flow follow it to the infinite end of the wave", which is indeed extremely efficient to solve the problem that the original ratio mode can only pass the green light at a time, and the traffic flow can only travel the distance of the green light multiplied by the legal speed. Ideal for cities with small to medium numbers of vehicles. Modern cities are huge and the number of vehicles is also huge. ...

Problems solved by technology

Modern cities are huge and the number of vehicles is also huge. All the roads including non-arterial roads are full of traffic. Only the arterial roads are smooth and smooth are far from meeting the actual needs, which leads to problems: expressways / green wave arterial roads are smooth = "traffic flocks to arterial roads =" Arterial road congestion, can not be resolved for a long time

The traffic optimization research based on the linear green wave system requires a lot of coordination factors and complex processes, and often loses sight of the other, and all the obtained solutions are ineffective. Even in the context of the emergence of many intelligent methods since the 1970s, traffic signal control is still at a standstill. embarrassing situation

The basic control module "arterial line-type green wave technology" does not provide high-efficiency traffic control in crossing directions, forcing surface traffic to gather on arterial roads, resulting in "technical inherent congestion". General Signal Module
