Vehicle Speed Reduction Based on Authorized Speed Limits

Abstract Keeping vehicle speed under control according to the speed limit is considered the main key to the traffic departments in the world to reduce vehicle accidents. This paper presents a prototype of a novel idea to control vehicle speed automatically according to the types of roads that the vehicle passes through without human intervention. The Micro-controller unit is interfaced with the RF receiver at the prototype, also with the RF’s transmitters deployed along the hypothetical pathway. The results show a valuable response for controlling a vehicle’s speed according to the speed limit of different types of roads.
