Motorcyclists' speed and “looked-but-failed-to-see” accidents

► In this study, we examined the influence of motorcyclists' speed on their involvement in 'looked-but-failed-to-see' (LBFS) accidents at junctions. ► This study is based on in-depth study and precise kinematic reconstruction of accident cases involving motorcyclist and another road user. ► The results showed that in urban environments, motorcyclists' speeds involved in LBFS accidents are significantly higher than in other accidents. ► In rural areas, the results are not significant. ► Speed management, through different means, could contribute to preventing LBFS motorcycle accidents at junctions, at least in urban areas.
