The study about the potential benefits of MAEB utilised a limited in-depth crash database to produce estimated speed reductions due to the system when considering the actual rider behaviour and an additional set of possible behaviours at the precipitating event in each crash available.
Special emphasis is given to the hypothetical early reaction of the rider who performs an optimal braking manoeuvre. This hypothetical behaviour could represent what an experienced rider is able to do, although it is not obvious that even an experienced rider can handle the braking task in emergency. A limitation of this study is that lateral avoidance manoeuvres are not contemplated when evaluating the hypothetical outcomes of the emergency event for experienced riders. Nevertheless, in most of the investigated cases the impact speed was below the threshold at which lateral avoidance is more effective than braking.
