URBAN TRANSPORTATION NOISE REDUCTION

THE FINDINGS OF THIS PROJECT ARE DIVIDED INTO THREE MAJOR AREAS: 1. THE HUMAN TOLERANCE TO TRAFFIC NOISE WAS EXAMINED AND RECOMMENDATIONS WERE MADE REGARDING MAXIMUM NOISE LEVELS FOR INDIVIDUAL VEHICLES AND ACCEPTABLE NOISE LEVELS FOR VARIOUS LAND USES. 2. HIGHWAY NOISE COMPLAINTS WERE EVALUATED AND A PROCEDURE FOR ESTIMATING NOISE LEVELS WAS RECOMMENDED. THIS PROCEDURE INVALVES THE USE OF AN INEXPENSIVE LAND-HELD SOUND PRESSURE LEVEL AND PERIODIC SAMPLING OF THE SOUND PRESSURE LEVELS. A DETAILED PROCEDURES MANUAL ON THE CONCEPT HAS BEEN PROVIDED. 3. THE UTILITY OF SEVERAL THEORETICAL METHODS OF ESTIMATING THE MAGNITUDE OF THE NOISE REDUCTION RESULTING FROM A BARRIER WALL WAS ANALYZED, AND THE RELATIVE ACCURACY OF THE DESIGN GUIDE PROCEDURE (NCHRP REPORT 117) FOR ESTIMATING NOISE LEVELS ON EXISTING AND PROPOSED FREEWAY FACILITIES WAS EVALUATED. IT WAS CONCLUDED THAT THE USE OF FEHR'S EQUATIONS TO PREDICT THE NOISE REDUCTION IS BOTH PRACTICAL AND ACCURATE WITHIN ACCEPTABLE ENGINEERING LIMITS. FURTHER, IT WAS CONCLUDED THAT THE DESIGN GUIDE PROCEDURE YIELDS VALID ESTIMATES OF TRAFFIC NOISE. PRACTICAL AND ACCURATE WITHIN ACCEPTABLE ENGINEERING LIMITS. FURTHER, IT WAS CONCLUEDED THAT THE DESIGN GUIDE PROCEDURE YIELDS VALID ESTIMATES OF TRAFFIC NOISE.
