Intersection traffic guide system

Abstract

The invention discloses a traffic guidance system at a crossroad, which comprises a traffic light device, an LED lamp group, an LED lamp group controller, a vehicle detection device and a laser projection device; the LED lamp group is arranged on a zebra crossing of the road; the LED lamp group controller Connected to the traffic light device, used to obtain the remaining time for pedestrians to pass in the traffic light device, and control the LED light group according to the remaining time; the vehicle detection device is arranged above the intersection to detect vehicles waiting to pass in different lanes at the intersection. The length of the road occupied by the vehicle; the laser projection device is set above the road, and is used to project on the road behind the last vehicle in the detected lane according to the length of the road occupied by the vehicle detected by the vehicle detection device Turn sign for this lane. The crossroad traffic guidance system of the invention effectively improves the safety of pedestrians crossing zebra crossings and vehicles crossing crossroads.

Description

technical field [0001] The invention relates to a crossroad traffic guidance system for guiding cars and pedestrians to pass. Background technique [0002] With the continuous increase of urban population and motor vehicles, the problem of urban traffic safety has become increasingly prominent.
