The Development of Socrates in Europe

SOCRATES stands for “System of Cellular RAdio for Traffic Efficiency and Safety”. This paper provides an update on what many consider to be the technology with the greatest potential for successfully achieving the realisation of an Integrated Road Transport Environment (IRTE). SOCRATES is a complete system: developments within the SOCRATES projects include applications, in-vehicle equipment, information centres and system architecture, as well as communications. However, one of the key areas within the SOCRATES research concerns the potential future communications system and this paper will cover this area in particular. DRIVE Central Office has given the responsibility to the SOCRATES Kernel project to investigate how applications and communications bearers (particularly mobile) may be integrated in an efficient and standardised way.

Integrated Communications Architecture for Road Transport Informatics

1991-10-01

The field of Road Transport Informatics (RTI) has spurred a substantial interest in the development and adaptation of a diverse range of technologies for vehicle-infrastructure communications. Candidate technologies for early implementation include FM RDS-TMC, short-range beacons and cellular mobile radio GSM. This paper reviews some of the major characteristics of these systems and debates some of the issues influencing the design and integration of communications technologies for RTI. Next, a possible integration framework which essentially acts to decouple RTI applications from communications networks is described. The aim is to facilitate end-to-end communications between any two application systems which need to communicate, regardless of the network to which each is attached. This concept leads to the notion of a virtual RTI network and is currently under investigation to determine its viability and applicability.
