论文摘要
超速超速是尼日利亚的重要问题。尼日利亚联邦道路安全委员会的报告显示，超过超过50％的道路撞车事故直接造成了该国的50％。特别是在高速公路上的速度颠簸并未被证明是解决方案。他们宁愿为问题做出更多贡献。基于由IEEE 802.11p标准定义的专用短范围通信（DSRC）系统的出现，我们提出了基于射频的速度颠簸，以模仿传统的速度断路器的操作。该型号由一个路边单元和车载单元组成，该单元与已安装的车辆中已安装的速度限制器配合使用。在我们的工作中，我们证明了基于RF的模型能够以10 m/s2的建议速率在80 m的方便停止距离内减速。我们的工作还表明，基于信号强度的自适应速度限制系统可以用作GPS的可靠替代品，从而消除了设计中对其他硬件的需求。
Over speeding is an important problem in Nigeria. The Nigerian Federal Road Safety Commission report shows that over speeding is directly responsible for over 50 percent of road crashes in the country. Speed bumps particularly on highways have not proved to be the solution; they rather contribute more to the problem. Based the advent of the dedicated short range communications (DSRC) systems defined by the IEEE 802.11p standard, we proposed a radio frequency based speed bump to mimic the operation of traditional speed breakers. The model consists of a roadside unit and an in-vehicle unit that works with the already installed speed limiter in vehicles. In our work, we showed that the RF based model is able to decelerate the vehicle at a recommended rate of 10 m/s2 over a convenient stopping distance of 80 m. Our work also showed that signal strength based adaptive speed limiter systems can be used as a reliable substitute to GPS thus eradicating the need for additional hardware in the design.
