Decision support system for fleet management based on TETRA terminals geolocation

In this paper, the localization of Terrestrial Trunked Radio (TETRA) terminals has been exploited to enable advanced management strategies in emergency events. The location awareness of the available handheld and vehicular terminals in the monitored territory is fundamental for a centralized supervision and control. In this context, the proposed system architecture extends the potentialities of the TETRA technology supporting the interactions between the control center and the end users with a mobile App installed on tablet platforms. A set of advanced functionalities have been implemented to optimize and support through user-friendly interfaces the most frequent procedures of operational units. The system has been experimentally tested on the TETRA network of the Autonomous Province of Trento, Trentino, Italy, and is under testing by the main officers of the local operational units.
