SafeTRIP: A bi-directional communication system operating in S-band for road safety and incident prevention

SafeTRIP is a project in progress partially financed by the Seventh Framework Programme's (FP7) European research and development activities in the subtheme of Sustainable Surface Transportation. SafeTRIP intends to implement a demonstrator of an integrated system, from data collection to service provision, that aims at optimising the use of road transport infrastructures. In this paper a general overview of the SafeTRIP architecture is presented. A detailed analysis and description of the functionalities characterizing the main elements of the system and a brief description of infomobility services such as alerting, disaster recovery and dynamic traffic data is given. A relevant part of this architecture is the Satellite Communication System which operates through the W2A Geostationary Satellite. To have an idea of the potentialities of the proposed system, a summary of functional requirements and performances relating to different types of services implemented is reported.
