A tracking system in vehicles is implemented and designed in such a way that it tracks the position of the vehicles within a given associate of time. The proposed system uses an application-oriented tracking design with the help of the technology Global Positioning System (GPS). This system utilizes android mobile as a peripheral for receiving the required information. Here Global System for Mobile (GSM) and GPS modems along with processor are used to install in the vehicles. Using General Packet Radio Service (GPRS), the locality of the moving vehicle can be continuously reported and updated to the server. The plot of the data acquired through GRPS will be displaying the accurate position of the vehicle with the help of Leaflet Maps on a monitoring device. Here SIM900D module is used which incorporates GPS and GSM modules. Also, the vehicle’s location-coordinates are obtained with the help of a GPS module. GSM module sends the coordinates data to monitored devices. At initial, the GPS continuously takes input data and is used to get a vehicle’s location coordinates. For tracking the vehicles, a message is sent to the GSM device, so that it can be activated. Once it is operated, the GSM module takes the last received data of latitudinal and longitudinal positions from the buffer and sends a message to registered devices. With the above application, we are adding a proximity sensor that detects the speed of other vehicles and specifies the distance of that vehicle, which indeed helps as an accident alerting mechanism.
