Accident Prevention System for Public Transport Vehicles

Human life loss is biggest loss which cannot be recoverable unlike other property loss. Many people die every year due to road accidents. Plenty of solutions have been applied to prevent these road accidents. Government bodies designed stringent rules and regulations about road traffic and speed. Good road infrastructures have been developed, many road safety initiatives have been executed. Different technologies and methods have been developed to train safe driving but most of them failed to prevent accidents. This paper proposes a real-time on board accident prevention system with major focus on public transport buses. Proposed system monitors some of vehicle parameters like vehicle speed, engine speed, brake pedal status and steering angle. All these parameters are measured by microcontroller based embedded board. Objective of this is to understand driving style of driver based on acceleration and brake pedal operation. If driving pattern falls under pre-defined rash driving criteria, system indicates driver about it and if situation continues, speed limiting is applied to vehicle at the same time text message is send to nearest police control room using GSM module. System also controls speed of vehicle in high density population area like cities and villages on the route. Using GPS module system monitors vehicles current location and if it comes under city area, vehicles speed is limited to safe limit. These above mentioned features makes system self-decision making driving supervisor which helps drivers to improve their driving skills and also prevent accidents and also intentional rash driving.
