This report covers the final design and implementation plan for evaluating the effectiveness of FMVSS 122: Motorcycle Brake Systems. The plan for the evaluation study considers measurability criteria, alternative statistical techniques, laboratory tests, data availability/collectability, resource requirements, work schedule, and other factors. The overall objective of the standard is accident avoidance. This objective is to be achieved by specifying required equipment for motorcycle brakes and establishing performance test procedures for these systems. The goals of the standard are to improve motorcycle braking performance by increasing stoping capabilities and decreasing stopping distances, and to avoid accidents by insuring safe motorcycle braking performance under both normal and emergency conditions. The extent to which the standard achieves these goals is obscured by the fact that accident-avoidance braking performance requires rather precise hand and foot coordination, and is highly dependent upon the braking abilities of the rider. The plan described in this study contains five coordinated evaluation programs, plus one for determining additional costs due to the standard. The first study analyzes mass accident data in relation to accident avoidance, injury reduction and effects of brake failure. The second study is a three-part data collection survey of motorcycle riders, tires, and modifications made to motorcycles. The third study, an analysis of NASS and California accident data, is very similar to the first task. Study number four is a dynamometer test of motorcycle brakes in a controlled laboratory setting. The fifth task uses volunteer and professional riders to test the performance capabilitiles of motorcycle brakes and to analyze the behavior of motorcycle riders. The last study is the cost data analysis. In summary, the entire program would require approximately five staff years of effort, would take three years to complete, at a total cost of $348,000.
