The conventional road speed bumps has the shortcomings such as the irregularity of the vehicle, the damage to the vehicle and the poor comfort of the passenger. In order to reduce the negative influence of the speed bumps setting, a kind of adjustable speed bump based on the adaptive theory has been Proposed. The speed bump can adjust the lifting and lowering state of the deceleration zone according to the vehicle speed information and the identification of the driving intention of the driver. The adjustable speed bump has double-wing hydraulic lifting structure, the soft-state slowdown with the mechanical energy into electricity, to achieve energy storage and utilization. The speed bumps has the principle of reward safe driving and punishing the radical driving. It can reduce the damage and noise pollution to the lowest level and improve the level of traffic stability, which reflects the fairness of ITS. The results show that the adjustable speed bump has remarkable effect in improving traffic safety, regulating driving behavior and improving traffic environment.
