A Fleet Telematics System (FTS) allows the information exchange between a commercial vehicle fleet and their central authority, i.e., the dispatching office. A FTS typically consists of mobile Vehicle Systems (VS) and a stationary Fleet Communication System (FCS). The FCS may be a stand-alone application maintained by the motor carrier or an internet service running by the supplier of the system. The FCS usually includes a database in which all vehicle positions and messages are stored.
