Design and Construction of An automated Vehicle Speed Control system for public service vehicles.

Abstract

As far as automobiles are concerned, safety is very important to reduce the occurrence of accidents in speed restricted zones as it minimizes the loss of property and life. Currently, vehicle speed control in Uganda is managed by use of road traffic signs indicating the speed limits in various zones and by traffic police monitoring speed inconsistencies using a radar gun in some areas. The challenge with the radar speed guns is that they only work where traffic officers are and cannot operate without human presence. In addition, the ratio of officer to vehicle is inadequate for the speed control and monitoring to be effectively performed by traffic police. Our project seeks to devise a novel solution to automatically regulate vehicle speed as it approaches a speed restricted area. This automated speed controlling system is built using the microcontroller-based platform of the Arduino Uno and Arduino Mega boards. Here the Arduino is programmed in such a way that, the prescribed speed limit is incorporated in the transmitter unit which transmits the signals, and it was received by the receiver in the vehicle using radio frequency wireless communication technology and the speed of the vehicle is automatically controlled by these input signals at the receiver. We discussed our findings on how to improve the current system, developed and integrated a working prototype of our proposed system and then gave further recommendations for future work that can be done to improve our system.
