The procedures used by the Wisconsin Department of Transportation for determining the number and locations of sampling stations for its truck weight study are described. The purpose of the program is to collect representative trucking characteristic data for use in pavement design, highway cost allocation, motor carrier enforcement, and other planning and research activities. Previous weight studies have produced data of limited value due to inadequate road type and geographic coverage. In addition, stations are selected without statistical guidelines for sampling. The use of new weighting-in-motion technologies and the emphasis on the collection of basic weight data permit a more random selection of weigh stations and a more comprehensive sample of truck traffic. The sampling plan developed relies heavily on user needs and statistical criteria to help ensure a valid and meaningful sample. By using data from the 1980-1981 highway performance monitoring system Wisconsin truck weight case study, the number of required stations is calculated on the basis of the average variability of truck weights in the state. These stations are distributed across recommended road types in proportion to the size of the total population (truck vehicle miles of travel) on each road type. Stations by road type are assigned to counties by using a weighted random numbers procedure. Criteria are presented for selecting corridors and sites where stations should be established. This type of sampling approach can generate more representative and comprehensive data that better describe the truck population. (Author)
