System and method for guidance and control of highway on-ramp merge area

Abstract

The invention provides an expressway entrance ring road converging zone guiding control system and method. The expressway entrance ring road converging zone guiding control system comprises intelligent car-mounted equipment and a road side converging guiding controller. The road side converging guiding controller is arranged within a certain distance range from a ring road connecting-in point on the outer side of an expressway. The certain distance range is a preset value. The intelligent car-mounted equipment comprises a car information collecting module, a car-mounted end wireless communication module and an information displaying module. The road side converging guiding controller comprises a road side end wireless communication module and an intelligent analysis module. According to the system and method, the converging traffic state of a converging zone can be collected and analyzed quickly and effectively, cars on a main road and the conveying zone are guided intelligently, traffic accidents are avoided, and the traffic efficiency and the safety of the expressway are improved.

Description

technical field [0001] The invention belongs to the field of intelligent traffic safety control, and in particular relates to a guidance control system and method for a merge area of ​​an expressway entrance ramp. Background technique [0002] In the merging area of ​​the entrance ramp of the expressway, the ramp vehicle first accelerates on the acceleration lane, and at the same time looks for the merging gap on the outermost lane of the main line. When there is a gap that can be merged into, the vehicle performs a merge operation and enters the outermost lane of the expressway. As the ramp-merging vehicles interfere with the vehicles traveling on the main line, it is easy to cause traffic accidents such as rear-end collisions and collisions. The main reasons for frequent accidents in expressway merge areas include: [0003] 1. Due to the readjustment of the position and speed of the vehicles on the main line due to the merging of vehicles, once the safe distance for driv...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the readjustment of the position and speed of the vehicles on the main line due to the merging of vehicles, once the safe distance for driving is not met, it will cause the risk of following vehicles on the main line

[0004] 2. The safety distance of merging vehicles is too small, which may easily cause the risk of following vehicles on the ramp

[0005] 3. When the traffic flow on the main road is heavy, it is difficult for ramp vehicles to merge in on the acceleration lane, and even when driving to the end of the acceleration lane, a suitable gap for ingress cannot be found. There is a risk of collision or side collision with vehicles on the main road

The domestic patent "Intelligent Safety Early Warning Control Method for the Merge Area of ​​Expressway Entrance Ramp" (Application No.: 201010219558.0) proposes a ramp early warning method. This method can quickly and effectively collect and analyze the actual traffic conditions in the merge area. Vehicles in the area can perform real-time dynamic early warning, but it uses the display screen installed on the roadside to provide early warning prompts. Vehicles that have passed the display screen cannot obtain new early warning information, and cannot perform precise import guidance control for a single vehicle
