The successful implementation of Automated Vehicle Control Systems (AVCS) depends on the reachable private and public benefits. Therefore, the profitability of the system has to be proven. The traditional assessment tool for both is the cost-benefit analysis. The paper presents a general methodological framework, which allows using the cost-benefit analyses for all kinds of AVC-systems. Main focus lies on the assessment of benefits. Therefore, a traffic simulation model is introduced that enables the direct calculation of benefits coming from the traffic effects of an AVC-system. As an example, a cost-benefit analysis is undertaken for the CHAUFFEUR-system.
