Vehicle guidance auxiliary signal control system and method in waiting area based on ground light board

Abstract

The invention discloses a ground lamp board-based waiting area vehicle guidance auxiliary signal control system and method. A lamp board controller is connected with an intersection signal controllerand a lamp board, and the intersection signal controller is connected with an intersection signal lamp; the lamp board controller I also connected with a plurality of coil detectors; the lamp board islaid on a through lane at a current intersection exit lane; the plurality of coil detectors are laid on a through lane of an intersection entrance lane in a line at equal intervals; the plurality ofcoil detectors are used for detecting vehicle queuing length and uploading the vehicle queuing length to the lamp board controller; the lamp board controller calculates actual length of lighting of agreen area of the lamp board according to the queuing vehicle length; the lamp board controller controls the green area of the lamp board to start to light according to the obtained actual length of lighting of the green area of the lamp board and time of starting to light of the green area of the lamp board, thereby controlling vehicles passing; and vehicles are guided to pass the current intersection through preset speed of shortening of a red length or lengthening of the green area in the lamp board.

Description

technical field [0001] The invention relates to a vehicle guidance auxiliary signal control system and method in a waiting area based on a ground light board. Background technique [0002] The design method of the traditional vehicle waiting area is: first determine the position of the conflict point between the current phase and the previous phase, then reserve a safe distance in the direction of the incoming vehicle of this phase, and finally extend to the stop line. This method of vehicle waiting area design can improve the traffic capacity of the intersection, but it is very limited. [0003] When the vehicle waiting area is designed to be short, there will be the following problems. When the green light of the previous phase is turned on, the queued vehicles are allowed to enter the vehicle waiting area, but the length of the waiting area will gradually spread among the queued vehicles, only to The effect of moving some vehicles forward has no effect on the rear queuin...

AI Technical Summary

Problems solved by technology

[0004] When the vehicle waiting area is long, there will be the following problems. When the green light of the previous phase is turned on, the queuing vehicles are allowed to enter the vehicle waiting area, and the queuing vehicles move forward as a whole but cause secondary parking, which not only increases the driver's workload Difficulty driving also causes environmental pollution and waste of resources

[0005] The invention patent "Urban Intersection Comprehensive Waiting Area Optimization Device and Its Control Method" proposes a vehicle waiting area setting method and its control method, but it is only applicable to intersections with specific conditions, and its applicability is low. And increase the driver's driving difficulty and psychological load

[0006] The literature "Analysis of Delayed Start Strategy of Vehicles in the Straight Waiting Area at Intersections" proposes a delayed start strategy for vehicles in the waiting area, which delays the time for vehicles to enter the waiting area to achieve the purpose of reducing secondary parking. Intersection control only plays an auxiliary role
