Deceleration deceleration zone is realized by affecting driver's driving mentality. When the vehicle at a high speed by the deceleration zone during deceleration zone specification, severe vibration from the tires will be passed to the driver through the body and the seat, the vertical curve can generate a vertical acceleration deceleration with pictures, have a strong physiological stimuli (including vibration stimulation and visual stimuli) and mental stimulation. Physiological stimuli induce a strong driver discomfort, and mental stimulation is deepened doubts unsafe driver, further reducing the driver's sense of security on the road environment. Ideal deceleration zone must ensure does not occur when the vehicle passes through the vehicle out of control, critical security component will not create a hazardous condition breakage, should have a higher ride and structural safety. Therefore, the ideal speed humps should have the following features: As the speed increases, after driving safety down to a certain extent can be maintained at a stable level and even increased. Comfort with increasing vehicle speed rapidly deteriorating human comfort when driving at speeds below the speed limit at a high level, higher than the speed limit while the vehicle speed is less than 85 percent of all speeding vehicles deceleration zone species, higher than 85% of all speeding vehicles when the vehicle speed can be maintained at a stable low level. Effect deceleration zone depends largely on the speed of the vehicle. Therefore, to ensure driver's safety and comfort, to set the speed limit must be reasonable, scientifically designed with the geometry of the road deceleration zone road deceleration, the deceleration zone, Xin bar fence fence by Xinxiang City Xin Metal Products Co., Ltd..
