摘要：This paper embed the various GPS services into a system so that many problem related to transportation system can be resolved in real time by providing data and information into our own pre-set format and provide individual vehicle data such as location and velocity by using GPS, estimated time of arrival, the speed count, number of passengers and seat availability and these details can be sent to passengers by SMS using GSM technology. Till now a date, no such kind of a system is exists which provides all kind of a result we want for any types of vehicles. This research project is aimed to design with an embedded system which will use for tracking and positioning of vehicles with GPS. The initial data will be captured by GPS device. Again the captured data will be sent to one data cleaning device and finally it is considered as an input file for data parsing tool for analysis purpose. With the use of data parsing tool the next processing will be done. This project also uses sensors to detect the speed of vehicle, passengers present in the bus. The Microcontroller is programmed to control and display the information according to the received signal from the GPS and sensors placed satellite and the position of a satellite implies that the GPS receiver is on the surface of a sphere centered at the position of a satellite. Thus the indicated position of the GPS receiver is calculated.
