Age dependence of attitudes and knowledge in cyclists.

A number of factors related to bicycle accidents were studied, namely, knowledge of priority rules, attitude and self-reported behavior regarding traffic rules, and general opinions about the safety of the traffic behavior of cyclists and drivers. In order to get an indication of the influence of these factors at different stages of the life span, subjects ranging from 9 to 83 years of age were represented in the study. The relationship between age and the various measures was found to be U-shaped in most cases. The older cyclists and the 9 to 11 year olds, the two groups that are most at risk, were deficient regarding knowledge while showing the most positive attitudes. Implications with respect to possible counter measures are discussed.
