The GPS module reports it's location (usually to within a couple of meters). You would need one per vehicle. No special plan is needed to capture GPS location data.
Communicating the GPS data between vehicles, or from the vehicles to a central location would require some sort of radio or cellular data connection. Cellular would require a cellular plan of some sort. Some types of radios require a license.
This consisted of an Arduino board with an EM-406a GPS and Radiometrix NTX2 narrowband FM module.
