Underground interchange rear-end collision prevention method based on visual perception

Abstract

The invention provides an underground interchange rear-end collision prevention method based on visual perception. According to the principle of inverse perspective, LED screens are arranged accordingto a density gradient from dense to sparse; LED screens with two colors are selected to be alternatively arranged based on cue discontinuity effects; and according to the related theory of color psychology, the colors of the LED screens are set to be red and yellow. In comparison with the prior art, as the LED screens with different colors are arranged alternatively in a density gradient from dense to sparse, a driver is guided to underestimate a distance, a vehicle distance is increased, and a rear-end collision accident occurrence probability is reduced; as the color psychology theory is applied and the red and the yellow which can enhance stimulation are selected as the arrangement colors of the LED screens, a role of warning the driver is played; and rear-end collision accident occurrence can be effectively reduced from angles of guidance and control, and safe and efficient operation of the underground interchange is ensured.

Description

technical field [0001] The invention relates to intelligent transportation technology, in particular to a method for preventing rear-end collision of underground interchanges based on visual perception. Background technique [0002] In recent years, my country's urban ground roads have been in short supply, traffic congestion, exhaust, and noise pollution are serious. With the promulgation and implementation of the "Code for Design of Urban Underground Road Engineering", underground interchanges have developed rapidly. However, the harsh underground traffic environment can easily lead to traffic accidents, and most accidents are rear-end collisions. Analysis of the cause of the accident shows that due to the low illumination and high concentration of pollutants in the closed underground environment, the contrast of visual stimuli in the space decreases, causing drivers to overestimate the distance between vehicles, resulting in the phenomenon that the distance between vehicl...

Problems solved by technology

The bayonet system can only be set up in one place, and the cost is high; the vibration markings are easy to cause the vehicle to skid and other behaviors in a closed and humid underground environment, posing safety hazards; the speed limit signs are difficult to identify in the underground space with low visibility. With little success
