Problems solved by technology

Research on traffic flow theory shows that the driver's collision avoidance behavior is related to the driver's reaction and the distance between the front and rear vehicles. The high proportion of rear-end collisions and collisions with buildings indicates that the driver may have a wrong response and a perception of the distance between vehicles. ,Misjudgment

Embodiment Construction

[0022] The present invention will be described in detail below with specific embodiments and with reference to the accompanying drawings.

[0023] A method for setting a self-illuminating street lamp for reducing rear-end collision accidents on expressways, comprising the following steps:

[0024] 1) On the lanes of highways where rear-end collision accidents are high or prone to occur, set self-luminous street lights according to the design method of gradient edge rate; self-luminous street lights are set above the original lane line of the expressway, and the long side centerline of self-luminous street lights is in line with The center line of the original lane line coincides.

[0025] 2) The light-emitting device of the self-illuminating street lamp is an OLED lighting device with adjustable luminous brightness, and its light color is yellow.

[0026] The design method of the gradient edge rate is as follows: starting from the length A in front of the highway section with...

Abstract

The invention provides a self-illumination road lamp setting method for reducing the rear-end accidents on an expressway. The method comprises the following steps of: 1) setting self-illumination road lamps according to a gradual-change edge rate designing mode on the lane of the road section with high risk or good chance of rear-end accidents on the expressway; and 2) selecting an OLED (organic light emitting diode) illumination device with adjustable illumination brightness for the illumination device of the self-illumination road lamp. According to the invention, the gradual-change edge rate designing mode is specifically designed, and sensitive edge rate self-illumination road lamps are arranged on the lane entering the road section with high risk of rear-end accidents on the expressway based on the visual perception edge rate of a driver, so that the subjective edge rate perception of the driver is improved, the speed perception is enhanced, the speed expectation is reduced, and the driver controls the driving speed of the vehicle of the driver and keeps the driving speed to reduce the rear-end accidents on the expressway, thereby comprehensively improving the driving safety on the road section with high risk or good chance of rear-end accidents on the expressway.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a self-luminous street lamp setting method for reducing expressway rear-end collision accidents and reducing the intensity of expressway rear-end collision accidents starting from the driver's visual perception characteristics. Background technique [0002] Vehicle rear-end collision and collision with fixed object accidents are important types of accidents. In 2010, a total of 3,906,164 road traffic accidents were reported across the country. Among them, the number of accidents and deaths caused by highway accidents increased by 5.2% and 4% respectively year-on-year. From the perspective of fatal accidents on expressways, 40.3% are tailgating collisions, 21.9% are collisions with fixed objects, and most of them are rear-end collisions between small vehicles and large trucks. At present, the main measures to control the distance between vehicles on expressway...
