Title: RESEARCH PAYS OFF: FLORIDA IMPROVES NOISE PREDICTION

Availability: Find a library where document is available Abstract: STAMINA 2.0, the computer program for predicting highway traffic noise, is used in project development to forecast the effect of traffic-generated noise on surrounding land uses and to assess mitigation measures such as noise barrier walls. The mainframe computer program, which was developed by the Federal Highway Administration (FHWA), is based on reference energy mean emission level (REMEL) data gathered in 1974 and limited to speed ranges from 48 to 97 km per hr. With the change in the national speed laws on designated roadways, the ability of the STAMINA 2.0 program to model noise levels accurately under these conditions became the subject of a research project. Through the Highway Planning and Research program of FHWA and the Florida Department of Transportation (FDOT), the University of Central Florida (UCF) was asked to update the REMELs on the basis of Florida traffic and to expand the speed range of these data. After extensive testing, FHWA approved the new REMELs (with speed ranges from 32 to 113 km per hr) for use in all of FDOT's programs for predicting traffic noise. A personal computer (PC)-based STAMINA program was developed by FDOT. It has on-screen graphics capability and runs efficiently on nearly any IBM-compatible PC. Benefits of the improved STAMINA 2.0 model include more accurate prediction of traffic noise levels, cost savings, and the substantial benefit that all noise assessments conducted by and for FDOT will use the same base data, which has led to more consistent and uniform noise prediction results and has eliminated any concern about the validity of studies performed using non-FDOT data.
