Design and implementation of an RF vehicle speed governor system in Zimbabwe.

Abstract

The proposed thesis is an attempt to address the problems of high fatalities as a result of over speeding in roads. Nowadays over speeding has become one of the major causes of most accidents in Zimbabwe. Generally, over speeding is the result of restlessness, bad behavior and negligence on the part of drivers. As the accident rates are increasing, it has become necessary to develop and implement a system which can automatically detect and control over speeding in vehicles. Nearly all major Zimbabwean roads are marked with speed limits, depending upon the size of moving vehicles and heaviness of traffic e.g. maximum speed for light vehicles is 120km/h and for heavy vehicles it is 80km/h, but some drivers habitually ignore these speed limits and results in serious fatal accidents. As an addition to other systems already in place, this research is making the use of the RF Technology to detect and control over speeding when so ever the subject vehicle exceeds the proposed speed limit on any or in most dangerous section of the roads. This project consists of two block units which are the transmitter unit and receiver units. The vehicle’s receiver unit will automatically reduce the vehicle’s speed accordingly once it receives a speed control signal from the transmitter.
