This report summarizes the work, which was performed under the task “Cost-Benefit-Analyses” within Autofore workpackage WP 700. It contains the assessment of the four options, which were recommended in WP 600 for the cost-benefit assessment. The four options are: - Annual inspection of passenger cars, - Additional inspection of new electronic vehicle components, - Roadside inspections of trucks, - Inspection of powered-two-wheelers. The most comprehensive cost-benefit analysis was performed for the option “annual inspection of passenger cars”, whereas the option means that annual inspection is introduced obligatory for passenger cars older than seven years. The benefit-assessment consists of safety benefits (accident-cost savings, congestion-cost savings), environmental benefits (lower environmental pollution and carbon-dioxide emission of passenger cars with petrol engine) and fuel consumption savings. The final benefit-cost ratio is 2.1, which shows that the introduction of annual inspections for passenger cars older than seven year is beneficial for the EU-25. Concerning the composition of benefits it can be stated that the safety benefits dominate the results. The other benefits (environmental benefits and fuel consumption) account only for one percent of the total benefits. Further potential benefits such as reduction of vehicle-breakdowns could not be integrated in the cost-benefit analysis due to the lack of empirical evidence. Beside the base case extensive sensitivity test have been performed to assure that the results are robust and reliable. The cost-benefit analysis for additional inspection of electronic vehicle components refers to the Electronic Stability Program (ESP). It makes use of a recent empirical study for ESP itself. Within Autofore it is assessed, which benefits could be secured if it is assumed that some ESP-system will not function properly. It is shown that the attainable benefits exceed the additional testing costs by the factor 2.6. The other options were considered for cost-benefit assessment. However, cost-benefit analyses were not performed because of the lack of European evidence (especially for roadside inspection) and the poor availability of statistical data for the vehicle-group of powered-two-wheelers.
