This paper describes the methodology for the assessment of the socio-economic impact of SAFESPOT applications. The applications selected for the assessment cover vehicle to vehicle (v2v) as well as vehicle to infrastructure (v2i) communication systems. The applications address main problem areas of road safety: accidents at intersections, accidents due to hazardous road and weather conditions and accidents due to over speeding and inappropriate distance. The assessment methodology relies in its core on cost-benefit analysis (CBA) as the most widespread tool to assess the profitabilityof applications form the society point of view. The assessment is howevernot limited to CBA but also considers the economic effects for particularstakeholder groups such as users, public authorities and the like. Their individual cost and benefits can be investigated in stakeholder analyses. Both elements, CBA and stakeholder analysis, form an integrated assessmentapproach which is applied here. The assessment makes use of the sound methodological base which was provided by projects such as SEiSS and eIMPACT.Some characteristics of co-operative systems however call for special attention within the assessment. Most prominently, the assessment will concentrate on a bundle of applications. The impact of this bundle will be assessed under the conditions of different business and service models. These issues will be addressed in the paper. Moreover, this paper also provides insight in likely patterns of results and first results of socio-economic impact assessment itself.
