HIGHWAY TRAFFIC NOISE PREDICTION FOR MICROCOMPUTERS: MODELING OF ONTARIO SIMPLIFIED PROGRAM

Since its publication in 1977, the FHWA highway traffic noise prediction model, STAMINA, has been used in many manual and computerized forms. In this paper, a streamlined but somewhat limited version of the STAMINA model, written in BASIC for use on personal or pocket computers, is presented. The BASIC version can be used to predict noise from highway traffic for many simple situations. The program predicts noise from three standard classes of vehicle at one receiver location, shielded by a barrier of infinite length. The model includes the free field case and two parallel roadways, and it is consistent with the assumptions made in STAMINA 2.0. The modeling and underlying assumptions are explained in sufficient detail to contribute to a better understanding of the STAMINA 2.0 mainframe program and the mathematical modeling in general. For the applicable situations, the accuracy of computation obtained is virtually the same as with STAMINA.
