Tunnel grating system for changing speed perception of driver and method for controlling same

Abstract

The invention relates to a tunnel grating system for changing the speed perception of a driver and a method for controlling the same. The tunnel grating system comprises a plurality of LED (light-emitting diode) lamps and a controller; the LED lamps are arranged on walls on two sides of a tunnel and arrayed along the tunnel direction; the controller is used for controlling the turning-on and off of the LED lamps; the LED lamps are in strip shapes; and the space between adjacent LED lamps is 1-5m. The LED lamps arranged on the same wall on one side are controlled to flash alternatively at an interval of 60-240ms with one LED lamp being bright and one LED lamp being dark alternatively or continuous N LED lamps being bright and continuous N LED lamps being dark alternatively, wherein the N is a positive integer ranging from 2 to 4. The speed perception of the driver can be affected by changing the visual perception of the driver so that the speed of the vehicle can be controlled.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a system and method for controlling vehicle speed in a tunnel. Background technique: [0002] With the rapid development of the economy, the demand for high-grade highways is increasing. Due to the terrain conditions, especially in mountainous areas, tunnels must often be built in order to ensure the grade of the highway. According to statistics, in 2003 (excluding Hong Kong, Macao Special Administrative Region and Taiwan Province), China had a total of 2175 highway tunnels, with a cumulative length of 1000 km. As the number of tunnels continues to grow and the level of motorization increases, accidents in tunnels are becoming more and more serious. The incidence of traffic accidents and accident fatalities in tunnels are much higher than those in ordinary roads. According to the statistics of traffic accidents in tunnel sections, more than 60% of traffic acc...

AI Technical Summary

Problems solved by technology

At present, the measures used to control tunnel overspeed mainly include vibration speed bumps, overspeed capture and speed limit signs, etc. However, the above methods of compulsory speed control have certain defects

Vibration deceleration starts from the driver's sense of touch. Vibration makes the driver feel uncomfortable when driving at high speed and forces the vehicle to reduce the speed. However, as the vehicle's vibration damping performance improves, the deceleration effect may decrease. In addition, the vibration will also cause certain damage to the vehicle; The speeding capture system is a post-event punishment deterrent method, and cannot be prevented in advance; the speed limit sign has a poor speed reduction effect due to the low compliance rate of drivers
