Vehicle lane change detection and control method for intersection induction control

Abstract

The invention discloses a vehicle lane change detection and control method for intersection induction control. The method specifically comprises the following steps: (1) determining the specific position of a vehicle detection point at an entrance road section of an intersection; (2) setting a guide lane vehicle detection point; (3) establishing a driving path pairing relationship and a directionjudgment rule between the vehicle detection points of the intersection entrance road section and the vehicle detection points of the guide lane; and (4) establishing a vehicle detection logic judgmentmechanism and a precise induction control logic algorithm, and implementing signal real-time induction control on the premise of accurately judging the passing requirements of the vehicle in different directions. According to the invention, the single setting and simplified control mode of the original vehicle detector are improved; multiple detection point linkage judgment logics are adopted, the passing direction of vehicles coming from the intersection is accurately judged, accurate induction control is executed, the vehicle passing efficiency is further effectively improved when inductioncontrol is implemented at the intersection, and control delay of the vehicles is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a vehicle lane change detection and control method for intersection induction control. Background technique [0002] Intersection induction signal control (referred to as induction control) is a control method that measures the traffic demand at the entrance of the intersection through the vehicle detector, and makes the signal green light time adapt to the traffic demand measured. It is suitable for the situation where the traffic at the intersection is not yet saturated and the random changes are large. The induction control has a good adaptability to the random arrival of vehicles, and can make the vehicles stop as little as possible before the stop line to achieve the effect of smooth traffic. Currently, it is used in cities in our country There are many mature applications at intersections. [0003] The implementation of induction control requires the install...

Problems solved by technology

[0007] The object of the present invention is to provide a vehicle lane change detection and control method for intersection sensory control, aiming at geometrical conditions such as left-turn or right-turn widening lanes, vehicles can turn around in advance from the left-turn lane or turn right in advance from the straight lane, etc. When sensing control is implemented at an intersection with certain conditions, the existing detectors cannot determine the actual direction of the vehicle or lack of precise control algorithms, resulting in control failure and increased vehicle control delays. The intelligent control method adopts the linkage judgment logic of multiple detection points to accurately judge the traffic direction of the incoming vehicles at the intersection and implement precise induction control, so as to further effectively improve the traffic efficiency of vehicles when the induction control is implemented at the intersection, and greatly reduce the control delay of vehicles
