摘要
介绍了一种全新的强制控速技术,根据液压原理,利用车辆速度变化引起的液体流量变化,自动进行速度识别.设定一个临界制动速度,对低于制动速度的车辆不起减速作用,对高于制动速度的车辆起减速作用.文章描述了智能控速路面工作的状态方程,研究了其设计长度、组数及应用领域,并对实验进行了分析.结论是智能控速路面对预防因超载超速引起的交通事故具有重要意义.
This paper has introduced a kind of new technology on controlling velocity. According to the hydraulic pressure principle, the liquid flow change, which is caused by the vehicle speed change, can automatically recognize the speed. This technology can only reduce the speed of vehicle whose speed is higher than the established critical speed. The paper has described the work equation of state about the intelligent controlling velocity road, studied its design length, the group number and the application domain, and analyzed the tests. The conclusion is the intelligent controlling velocity road can prevent the traffic accident because of overload and overspeed.
