Embodiment 1

[0035] This embodiment provides a countdown implementation method in the real-time optimization process of traffic signals, the process of which is as follows figure 1 shown, including the following steps:

[0036] Step S1: Attach figure 2 Take the intersection shown as an example. At the beginning of the cycle, before the first phase starts to pass, the time of green light, yellow light, and red light of all phases is counted, and the information of all light groups contained in each phase is counted; where:

[0037] 01——North-to-south traffic flow through light group;

[0038] 02——Lamp group for east-to-west traffic going straight;

[0039] 03——South to north traffic through the light group;

[0040] 04——West to east traffic through light group;

[0041] 05——Left turn light group for north to south traffic flow;

[0042] 06——Left turn light group for east to west traffic flow;

[0043] 07——Left-turn light group for south-to-north traffic flow;

[0044] 08——Left turn ...

Abstract

The invention discloses a countdown implementation method in a real-time optimization process of a traffic signal, and the method comprises the steps: making statistics of green, yellow and red light time of all phases and all light group information contained at each phase; calculating the red-light countdown time of a light group corresponding to a non-passing phase, the green-light countdown time of a light group corresponding to a current passing phase, the yellow-light countdown time of a light group corresponding to a current passing phase and the red-light countdown time of a light group corresponding to a current passing phase according to the green, yellow and red light time of phases; and transmitting the countdown time to a countdown board. The method guarantees that countdown information can be displayed accurately in the real-time optimization process of the traffic signal, and prevents the loss of the countdown information from causing the discomfort of a large number of drivers.

Description

technical field [0001] The invention relates to a traffic signal control method, in particular to a countdown realization method in the real-time optimization process of traffic signals. Background technique [0002] With the development of intelligent transportation on urban roads, people's requirements for intelligent transportation are getting higher and higher, so the traffic signal timing control in the traditional sense can no longer meet the needs of traffic signal control; at present, traffic signal control for urban intersections is becoming more and more The more inclined to real-time optimization, it is to adjust the green light time of each phase in real time according to the change of traffic flow, which directly leads to the continuous change of the time of each light group of traffic signals. In the existing intersection countdown technology, the self-learning countdown technology is generally used. This timing technology determines whether to display the time...
