SAMPLING PROCEDURE USING MULTISTATE TRAFFIC RECORDS TO SELECT ACCIDENT AND EXPOSURE DATA-COLLECTION SITES

This paper describes a sampling plan developed to select 80 field data-collection sites. At each of these locations, large-truck accident rates were to be measured and vehicle exposure was to be sampled simultaneously for 1 year. The problems to be addressed were (a) to stratify the sites in each state so that the accident experience developed would be representative of the state (to preclude selecting only high-accident locations) and (b) to devise a roadway typology whereby sites were consistent across states selected. Accidents are now being investigated at sites selected by this procedure in California, Maryland, Michigan, Nevada, Pennsylvania, and Texas.
