Problems solved by technology

[0002] For urban traffic intersections with large traffic flow changes, it is often encountered that there is no vehicle passing through the green signal lane, while vehicles in the other direction are waiting in line. The waiting time for vehicles to pass is too long, which seriously affects the efficiency of urban traffic operation.
However, most of the current road traffic signals do not have the phase adjustable and dynamic induction functions.
Although the investment in intelligent traffic management and control system (ITS) can solve the traffic control of the city well and improve the operation efficiency of urban traffic roads, for small and medium-sized cities, the adoption of ITS system not only faces large system investment, but also has support question

Embodiment 1

[0026] see figure 1 , figure 2 . The multi-phase hopping and vehicle full-dynamic induced traffic control method of the present invention utilizes a traffic signal machine to flexibly control traffic signals at an intersection, so as to improve the traffic capacity of vehicles in all directions at the intersection and reduce the total delay time of vehicles, comprising the following steps:

[0027] 1) Install upstream vehicle detectors and stop line vehicle detectors in each lane of the traffic intersection to detect dissipated vehicles and vehicle information entering the intersection in real time, and transmit them to the signal control system;

[0028] 2) According to the number of waiting vehicles in each lane of the intersection and the number of vehicles entering the intersection section, the system adopts the method of prioritizing traffic on busy road sections, automatically sends traffic signals to busy lanes, and induces vehicles in this lane to pass first;

Embodiment 2

[0032] see figure 1 , figure 2 . The multi-phase jump and vehicle full dynamic induction traffic control method of the present embodiment comprises the following steps: 1) The multi-phase jump induction control method is mainly designed for multi-lane intersections, and according to the vehicle traffic information of each lane of the intersection, through System scanning and the principle of prioritization of busy roads, automatically send traffic signals to busy lanes, and induce vehicles in this lane to pass first. Compatible lanes use the same phase, and phase jumps mainly occur between non-compatible lanes, which is different from the traditional multi-phase fixed-period fixed phase change mode.

[0033] Multi-phase jump induction control is based on the number of vehicles waiting in each lane or entering the intersection section, so it is necessary to set up upstream vehicle detectors and stop line vehicle detectors in each lane of the traffic intersection to detect di...

Embodiment 3

[0038] The multi-phase jump and vehicle full-dynamic induced traffic control method of this embodiment automatically changes the phase and the number of phases according to the number of waiting or entering vehicles in each lane of the intersection during actual control. During the phase jump, green flashing or yellow lights can be inserted according to the actual situation of road guidance. In one induction period, the phase jumps randomly according to the traffic flow, and the phase is set between 1 and 3. The multi-phase jump induction effectively solves the problems of blindness of vehicles at night roads and newly built intersections (such as no cars in the north-south lanes, east-west lanes, etc.) Driveway is occupied but closed to traffic).

[0039] The phase jump induction control mainly controls the green light signal of a certain lane at the intersection, by controlling the waiting vehicles in a certain lane (vehicles dissipating from green lights and red lights in t...

Abstract

The invention relates to an urban intersection traffic signal control method, relates to a multi-phase-jump and vehicle full-dynamic induction traffic control method, and aims to flexibly control traffic signals at intersections by using a traffic signal instrument so as to improve the traffic pass property of vehicles at the intersections and reduce the total delay time of vehicles. The method comprises the following steps: 1) setting an upstream vehicle detector and a parking line vehicle detector at each lane of a traffic intersection, and detecting dissipating vehicle and information of vehicles entering the intersection in real time; 2) according to the numbers of vehicles waiting in different lanes and vehicles running into the intersections, automatically transmitting passing signals to busy lanes by using a busy lane priority pass method through a traffic signal instrument control system so as to induce the vehicles in the lanes to pass prior; 3) by using a method that compatible lanes adopt one same phase and non-compatible lanes are subjected to phase-jump induction control, providing the priority pass right for lanes with a plenty of waiting vehicles or a lane into which a plenty of vehicles run. Due to the adoption of the method, a relatively good induction effect can be achieved at intersections with unsaturated traffic vehicles.

Description

technical field [0001] The invention relates to a traffic signal control method at an urban intersection, in particular to a dynamic vehicle induction control method with phase jumping for urban traffic intersections. Background technique [0002] For urban traffic intersections with large traffic flow changes, it is often encountered that there is no vehicle passing through the green signal lane, while vehicles in the other direction are waiting in line. The waiting time for vehicles to pass is too long, which seriously affects the efficiency of urban traffic operation. .
