Intersection safety auxiliary system based on holographic projection and control method thereof

Abstract

The invention discloses an intersection safety auxiliary system based on holographic projection and a control method thereof. The control method comprises steps that: a sound wave velocity measurementprinciple is adopted to determine whether a vehicle falls into a dilemma area, and a holographic projection principle is combined for speed guiding and warning; a ground lamp group arranged under a pavement marking is consistent with a traffic signal lamp for controlling passing of pedestrians, and the green lamp of the ground lamp group is controlled to flicker before the green lamp of the traffic signal lamp is about to turn; an auxiliary lamp group paved on a left side canalization line of each lane is consistent with the traffic signal lamp for controlling the passing of the pedestrians,and the green lamp of the auxiliary lamp group is controlled to flicker before the green lamp of the traffic signal lamp is about to turn. The invention is advantageous in that strong practicability is provided, intersection delay is reduced, and the cooperation between the pedestrians and the vehicles is effectively facilitated, and reasonable speed guidance is given to the vehicles, which are about to enter the dilemma area, so as to help drivers to avoid falling into the dilemma area by controlling the speed change.

Description

technical field [0001] The present invention relates to the technical field of traffic safety, in particular to a holographic projection-based intersection safety assistance system and a control method thereof. Background technique [0002] Traffic safety is a major traffic problem that countries all over the world are facing. Urban road traffic accidents often occur at intersections. Intersections are the "bottleneck" of road capacity in the road network and the "multiple sources" of traffic accidents. The existence of dilemmas is one of the important reasons for accidents at intersections. A dilemma zone is an area where a vehicle can neither pass the stop line nor stop safely inside the stop line during a yellow light. When the vehicle enters the dilemma zone, no matter what choice the driver makes, the phenomenon of sudden braking or running a red light will inevitably occur, which will easily lead to traffic accidents. [0003] At intersections with poor lighting cond...

Problems solved by technology

At present, the research on the intersection dilemma is mostly limited to the advanced vehicle-mounted equipment, which is in a theoretical research stage, and the implementability is poor.
