The SAFESPOT Integrated Project, started in February 2006, is a research project co-funded by the European Commission, under the strategic objective “eSafety Cooperative Systems for Road Transport”. Its goal is to understand how intelligent vehicles and roads can co-operate to produce a breakthrough in road safety. The system should extend in space and time the driver’s awareness of the surrounding environment, using wireless communication to enable vehicle-to-vehicle and vehicle-to-infrastructure co-operation through the IEEE 802.11p protocol. This paper presents the conceived architecture solutions, aimed at fulfilling the SAFESPOT system requirements in every kind of environment within the road network.
