The successful implementation of AHS depends on the attainable private and public benefits. Therefore, the profitability of the systems has to be proven. The common assessment tool for both is the cost-benefit-analysis. The paper presents a general methodological framework which allows to assess the social costs and benefits of any AHS. The methodology is exemplary illustrated by the CHAUFFEUR system. Main focus lies on the assessment of benefits. It is argued what are the benefits coming from the system use (direct effects and indirect effects) and what is required for assessment. Respecting benefit assessment a traffic simulation model is introduced that enables to calculate the benefits coming from the traffic effects immediately. The outcomes of the model are the input for a cost-benefit-analysis. The results of the CBA indicate that using CHAUFFEUR could lead to significant benefits for the society. This is illustrated for German as well as for Japanese motorways. For the covering abstract see ITRD E114174.
