Embodiment 1

[0063] This embodiment provides a method for adjusting the passing time of traffic lights at intersections, which is applied to figure 2 In the system shown, in this system, each traffic light intersection is provided with:

[0064] Several detection devices 10, in the present embodiment, the detection device includes several geomagnetic controllers arranged at each crossing and a geomagnetic controller for receiving geomagnetic signals, which are used to detect vehicle information on each lane, specifically, Whenever a vehicle passes the lane, it will be detected, and the detection device will output passing information;

[0065] The vehicle passing volume adjustment device 20 is an equipment for increasing the setting of this program relative to the prior art;

[0066] The intelligent control platform has a server 40 for receiving and storing the original vehicle passing data sent by the vehicle passing amount adjustment device.

[0067] Geomagnetism transmits the collect...

Embodiment 2

[0112] In this embodiment, on the basis of Embodiment 1, the congestion distance s in step S213 is n The determination method for is changed to the following:

[0113] Change the number of Internet engines from one to at least two to improve the data credibility of the system's judgment.

[0114] Now, the total number of Internet engines is z, and the congestion level coordinate point set includes the first congestion level coordinate point set ... the uth congestion level coordinate point set ... the z congestion level coordinate point set; z is the total number of Internet engines;

[0115] The uth congestion level coordinate point set is the congestion level coordinate point set fed back by the uth Internet engine, 1≤u≤z;

[0116] In this embodiment, z is equal to 2, and the Internet engine includes a navigation engine A and a navigation engine B.

[0117] Navigation engine A, after receiving the information from coordinate a to coordinate b sent by the server, the retur...

Embodiment 3

[0135] The present embodiment is on the basis of embodiment 1, with step S20: revise described on-site cycle time passing car number p 1 ,p 2 ..p n ....p m Obtain the information of the number of passing vehicles in the cycle time l 1 , l 2 ..l n ....l m ; Add the following steps:

[0136] In this embodiment, the correction method is designed with reference value data p n基 ,p n基 is the reference number of passing vehicles of the nth lane in the corresponding period. In this example, the p n基 Take the measurement average value of the intersection detection equipment within the set historical time.

[0137] p n基 Calculated from the historical cycle data of each lane, each geomagnetic field sets a reference value data every 10 seconds, which is consistent with the cycle data interval, and is divided into workday reference values ​​p n基工 , holiday reference value p n基节 , if the current time is a working day, use the working day reference value p n基工 To correct, if th...

Abstract

The invention discloses an intersection traffic light timing adjustment method, a terminal and a computer storage medium, and the method comprises the following steps: forwarding the on-site vehicle passing timestamp information to a server, and enabling the server to calculate the number of vehicles passing in the on-site cycle time according to the on-site vehicle passing timestamp information, correcting the vehicle passing number in the on-site cycle time to obtain the vehicle passing number information in the periodic time; receiving cycle time vehicle passing number information sent by the server; directly sending the vehicle passing number information in the period time to a signal machine, or respectively sending an analog signal to the (1-m)th detector interface of the signal machine in the cycle time, so that a signal machine adjusts intersection traffic light timing according to the passing vehicle number information. According to the invention, the on-site detection data of the detection equipment is corrected, so that the timing control of the traffic lights at the intersection accords with the actual situation of the intersection, and the traffic passing efficiency is improved.

Description

technical field [0001] The present disclosure generally relates to the technical field of traffic control, and specifically relates to a method and a terminal for adjusting timing of traffic lights at intersections. Background technique [0002] In the prior art, the control system for the length of traffic lights at each intersection is mainly through figure 1 The method shown, in this method, each city is equipped with a number of control centers, and each control center can at most control the signals at several intersections. Generally, 2-3 level control methods can be used to realize real-time control of each intersection in the city. Each signal machine obtains the information on the number of passing vehicles by receiving the detection equipment installed at its corresponding intersection, and then calculates the traffic time of the current intersection through the information on the number of passing vehicles; the cooperation of the signal machines at the associated ...
