Abstract
A new method, based on elementary probability theory, has been developed from estimating live load frequencies on highway bridges that may be expected from various types and levels of heavy motor vehicle operation. The main objective of the method is to provide a relatively simple mathematical basis for estimating approximately how often any specified sequence or group of two or more vehicles might be expected to occur on any particular part or length of bridge as a result of given or anticipated compositions, volumes, and speeds of traffic. In addition to making use of the frequency distributions of heavy vehicle loads obtained from loadometer surveys, the new method provides the means for estimating the frequencies of various intensities of live load which result from the change grouping of two or more heavy vehicles on a given part or length of bridge at the same time.
