Measurements of Disease

Of the three transportation modes (airplanes, automobiles, motorcycles), motorcycles pose the greatest risk. The rate of accidents in motorcycles is (3,000 accidents casesГ·10, 000 numbers of drivers=30%), automobiles (10,000 accidents casesГ·100, 000 numbers of drivers=10%), and airplanes (30 accidents casesГ·5, 000 numbers of drivers=0. 6%). Therefore, motorcycles have the highest accident rates (30%). In terms of occurrence of motorcycle crashes, age is a key determinant. In general, younger riders under the age of 40 are more likely to cause or be involved in motorcycle accidents (National Highway Traffic Safety Administration [NHTSA], 2001).
