The present generation requires the information time to time. The usage of technology has been increasing extensively from day to day. So, we are planning for combining the present technology with requirement of information and transmission and created “vehicle tracking and accident detection system using GPS and GSM”. In case of an accident it will sends an alert message through GSM along with location with the help of GPS module. The distinctive utility of this project is vehicle fall detection, if the rider falls down from the bike its sends message to registered mobile number. Fall detection measurement can be observed by accelerometer. This system is widely used in stolen vehicles, school/college buses and cabs.
