Why is traffic safety important?

Injuries from motor vehicle crashes are categorized into 4 main modes: those among the occupants of automobiles, motorcyclists, bicyclists and pedestrians.  There is a separate area for each of these categories, since the descriptions, risk factors, and prevention approaches are different for each.  Taken together, motor vehicle crashes were the leading cause of fatal unintentional injuries among Hawaii residents from 2008 through 2012, accounting for 17% of the total.  Motor vehicle crashes were also the 2nd leading cause of nonfatal hospitalizations for injuries (17% of the total), and the 4th leading cause of nonfatal injuries treated in the emergency department setting (10% of the total).  The figure below shows about half (48%) of the 571 residents who died in motor vehicle crashes were car occupants, 28% were riding motorcycles or mopeds, 21% were pedestrians, and the remaining 2% were bicyclists.  (IPCS considers all injuries to bicyclists as due to “motor vehicle crashes” whether they actually involved motor vehicles (cars, motorcycles, etc.) or simply resulted from cyclists falling off their bicycles.)
