TRL has carried out cost benefit analyses on behalf of the European Commission concerning Advanced Emergency Braking Systems AEBS and Lane Departure Warning Systems LDWS. These studies considered the costs and benefits for vehicles of categories N2/N3 (goods vehicles >3.5t GVW) and M2/M3 (buses and coaches with more than 8 passenger seats), but did not consider the effect on different types of vehicles within these categories. For this reason, The Commission tasked TRL to carry out a more detailed investigation to refine and improve the analysis and to consider the different types of vehicle within the above categories. Representatives of the EU commercial vehicle industry have also described some technical reasons why some vehicles and vehicle classes should be exempt from the AEBS/LDWS installation requirements. As part of this project, TRL has considered these arguments and undertaken a simple desk-based evaluation of them. The validity of these proposals has been assessed using publically available technical information and recognised engineering principles. This report presents the results from the project. These include the target populations (the accidents that could potentially be mitigated by AEBS or LDWS fitted to N2, N3, M2 and/or M3 vehicles) in Great Britain, Germany and France and uses those data and data from other published sources to estimate the overall numbers of fatal, serious and slight injury casualties that could potentially be avoided across the EU27. The report also describes an evaluation of the technical exemption proposals and combines the findings with vehicle-specific cost/benefit analyses to identify vehicles or classes of vehicle where the cost benefit ratios differ substantially from those derived for trucks and buses considered as a single group.
