Samenvatting
The Pennsylvania Department of Transportation's weigh-in-motion program is described. The Pennsylvania program differs from others in the country because of its base of support, which includes top management and program managers. This support, which was garnered in the initial months of the program, continues to guide the program and is responsible for the program's rapid growth and acceptance throughout the department. This support helped guide the development of customised truck size and weight reports by the Pennsylvania Transportation Institute. These reports analyse truck size and weight data on the basis of Pennsylvania truck weight laws and can be produced as a series of tables and graphs.
