Embodiment 2

[0130] On the basis of above-mentioned embodiment 1, the present invention also mentions a kind of expressway ramp merging control method, specifically comprises the following steps:

[0131] Step 1: According to the front-end data acquisition module, the movement and location information of vehicles on the main road and ramps are collected in real time through the two-way millimeter-wave radar;

[0132] Utilizing the all-weather and all-weather working ability and high detection accuracy of the millimeter-wave radar, the two-way splicing of the millimeter-wave radar is used to achieve the purpose of two-way perception, which can collect and analyze the traffic status in the merge area of ​​the ramp, and carry out intelligent holography on the vehicles in the merge area guide.

[0133] Step 2: According to the data analysis and processing module, use the noise elimination algorithm and the trajectory correction algorithm based on Kalman filter to obtain clean vehicle speed and...

Abstract

The invention discloses an expressway entrance ramp confluence control system and method, and belongs to the field of intelligent traffic control and management. The traffic state of a ramp confluence area can be rapidly and effectively collected and analyzed by utilizing the characteristics of all-day and all-weather working capability, high detection precision and the like of millimeter wave radar; intelligent holographic guidance is carried out on vehicles in a confluence area, so that the driving efficiency and safety of the expressway are improved; according to the invention, a noise target is eliminated by using a noise elimination algorithm and a vehicle driving track prediction algorithm based on Kalman filtering, pure driving data information of a vehicle is obtained, and a good noise filtering effect is achieved; based on a ramp confluence area accident prediction comprehensive algorithm, quantitative discrimination indexes of ramp vehicle conflicts under different conditions are formed, a final dangerous condition is determined according to a data fitting result, and an LED gives an early warning prompt, so that the vehicle-road cooperation capability and the confluence efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the field of intelligent traffic control and management, and in particular relates to an expressway entrance ramp merge control system and method. Background technique [0002] With the development of science and technology and the improvement of living standards, the number of cars in my country and the total mileage of highways have increased year by year, and the travel efficiency of residents has been greatly improved. However, with the development of regional economy and the further increase of traffic demand, highway traffic accidents occur frequently, among which the ramp merge area is the intersection of ramp and main lane, and the accident rate is quite high. [0003] At present, the incidence of accidents in the ramp merge area of ​​expressways in my country is high and the existing research has not proposed a reasonable solution to solve the accidents in the ramp merge area. After the team conducted market research t...
