Kinematics of powered two-wheelers at bends on intercity roads

In France, powered two-wheelers (PTWs) account for 18% of fatal accidents, and PTW riders are 27 times more
likely to be killed than car drivers. More than one-third (40%) of these fatal accidents occur at bends on intercity
roads. Based on this observation, a prototype vehicle embodying the full range of intrinsic and extrinsic parameters
was developed in order to analyse rider behaviour. The Rider Behaviour Analysis Motorcycle (Moto d’Analyse du
Comportement du Conducteur, MACC) was used to analyse speed and lateral acceleration, capture videos and
measure vehicle dynamics and trajectories. The findings revealed certain practices that had never previously been
quantified. Alongside this behavioural study, we will also highlight some key accident research statistics associated
with PTWs at bends on intercity roads.
