What is the height of the compulsory deceleration belt of the highway in China at present?
What is the highway deceleration belt?The installation on the road which passes through the deceleration of the vehicle traffic facilities, the shape of strip is also a dot, the main material is rubber, there is metal, usually with a yellow black and white to attract visual attention, make the road slightly arching to the vehicle deceleration, generally set the vehicle in the road crossing, industrial and mining enterprises, schools, residential entrance to slow sections and easy to cause traffic accidents Road, is used for the slowdown in motor vehicle speed of the new traffic special security settings. The deceleration zone greatly reduces the accidents at each traffic crossing, and is a new type of special facilities for traffic safety. The vehicle is safe in operation, cushioning and decelerating, and improving the safety of traffic crossing.
What is the height of the domestic highway deceleration zone?Deceleration belt is a kind of traffic to ensure pedestrian safety. At present, the width of hump type road deceleration belt is generally 300~500mm, and the height is generally 30~60mm.
What are the characteristics of a highway deceleration belt?With the increase of the speed, the safety of the vehicle can be maintained at a stable level or even improved when it is reduced to a certain extent.The driver's comfort in the road speed limit when the speed is lower than that at a high level, and less than 85% higher than the speed limit in all speed speeding vehicles when riding comfort rapidly deteriorated with the increase of speed and speed, more than 85% of all the speeding vehicles can be maintained constant at a low level. The use of the deceleration belt depends to a great extent on the speed of the vehicle. Therefore, in order to ensure the safety and comfort of drivers, the speed limit of the road must be set reasonably and the geometric dimensions of the speed reducer should be scientifically designed.
