Development of a New Highway Traffic Noise Prediction Model. Volume 4. Highway Traffic Testing of PSUHTRAN Validity

摘要

The volume describes the full-scale experiments that have been done to facilitate the development of the new highway traffic noise prediction model, PSUHTRAN, and to establish the validity of that model. Full-scale experiments have been conducted at three general locations. The first was a research site along a rural highway near Penn State University. The second was a set of freeway sites in the vicinity of Washington, DC, and the third was another set of sites in New Jersey. PSUHTRAN predictions are compared with available measurements and also, in some cases, with the predictions of the Federal Highway Administration (FHWA) Level 1 and Level 2 program, STAMINA. Attempts were made in the rural highway testing to establish procedures for defining the distribution of vehicle source intensity with vertical position on the vehicle.
