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 o

Example Embodiment

[0022] A vehicle lane change detection and control method used for intersection induction control, specifically including the following steps:

[0023] (1) Use the electronic police and bayonet devices already available at the intersection to measure the average speed of vehicles entering the intersection and passing the stop line during the green light period in each direction of the intersection, and determine the detection according to the distance correspondence table of the sensor control vehicle detector. The distance between the detector and the stop line of the intersection, so as to determine the specific location of the vehicle detection point on the entrance section of the intersection;

[0024] (2) Set a vehicle detection point in the guide lane at the center of the lane at the end of the guide lane at the intersection to determine which entrance lane the vehicle arriving at the intersection will ultimately choose to pass through the intersection; set the vehicle to ente...

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...
