Impact of Pavement Defects on Motorcycles’ Road Safety

Degradation of the pavement has a significant impact on road safety and, in particular, asphalt polishing turns out to be very hazardous for powered two wheelers. The paper reports the results of a study aimed at analysing the effects of asphalt polishing of pavements on the dynamic behaviour of motorcycles. A dynamic simulation code was used in order to understand the motorcycles dynamics parameters in different conditions, define a model of the dynamic behaviour of motorcycle and propose a useful tool for planning maintenance interventions based on the risk associated to the asphalt polishing of the pavement.
