Abstract

To obtain information on driving exposure in the province of Ontario, a mail survey of 12,019 drivers, stratified by age, sex and region of the province, was carried out. The return rate of completed questionnaires among eligible drivers was 36.0%. Results of the survey include data for the various age, sex and regional groups on age of obtaining license, employment as a driver, and global 12 month and 7 day estimates of driving distance. In addition, a trip diary of 1 to 3 days was used to collect information on the number of trips driven per day, mean distance and mean time driven per day. Data on collision rates per million kilometres by sex and age were calculated using 584,012 Ontario driver records and the data gathered in this current study. Collision rates per million km. for males decline from a high of 7.58 for 16-19 year olds to a low of 2.64 for 60-69 year olds, after which they begin to rise again. For females the rates are lower than those for men in the equivalent age group except for women drivers over 60.
