Intelligent vehicles and advanced safety technologies have been the subject of discussion for many years and there is now a large range of production and near-production systems that claim to have significant safety benefits. The Evaluation of Safety System Technologies project took a ‘bottom-up’ approach, starting with small number of specific safety systems and estimating the target population of casualties and cost benefit information for these systems. This was achieved using primarily in-depth accident data, with the results being scaled up to national level (adjusting for under-reporting). The analyses carried out as part of this study have evaluated the potential casualty benefits, and compared those to the likely system fitment costs, for four separate advanced primary safety technologies: Advanced Emergency Brake Systems (AEBS) for passenger cars; AEBS1 – potentially able to mitigate/avoid all moving target rear shunts but those with stationary targets only if closing speed 40 mile/h or less; AEBS2 – potentially able to mitigate/avoid all rear shunt impacts regardless of whether target (shunted) vehicle is stationary or not; Pedestrian capable AEBS for passenger cars; 0.6s/1s/2s systems – applies full braking 0.6s/1s/2s before a detected, imminent impact with a pedestrian; Lane Departure Warning Systems for passenger cars; Youth/Family key.
