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 a highway entrance ramp merging control system and method, which belong to the field of intelligent traffic control and management. The invention utilizes the all-weather and all-weather working ability and high detection accuracy of the millimeter-wave radar to quickly and effectively merge the ramps Collect and analyze the traffic status in the area, and conduct intelligent holographic guidance to the vehicles in the merge area, which improves the driving efficiency and safety of the expressway; this patent application uses the noise elimination algorithm and the vehicle trajectory prediction algorithm based on Kalman filter to analyze the noise target Carry out elimination to obtain pure vehicle driving data information, which has a good noise filtering effect; based on the comprehensive accident prediction algorithm in the ramp merge area, a quantitative discrimination index for ramp vehicle conflicts in different situations is formed. According to the data fitting results To determine the final dangerous situation, and the LED will give an early warning prompt, which greatly improves the vehicle-road coordination ability and merging efficiency.

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...
