基于自适应理论的可升降减速带设计

常规道路减速带在降低车速保证交通安全的同时,也存在设置不规范、易造成车辆损害、乘客舒适性差等缺点,为减少减速带设置带来的负面影响,提出一种基于自适应理论的可升降减速带。该减速带可根据车速信息及对驾驶员行车意向的识别,反馈调节减速带的升降状态。采用双翼型液压升降结构,可将软态减速带的机械能转化为电能,实现能源存储利用。该减速带奖"慢"罚"快"的工作原则,可在保障通行安全的前提下,将车辆损害、噪声污染降至最低,提高交通稳静化水平,体现了智慧交通的公平性。结果表明,该减速带在提高交通安全、改善驾驶行为、改善交通环境等方面效果显著。

Design of adjustable speed bump based on adaptive theory

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.
