SNAP 1.1: A Revised Program and User's Manual for the FHWA Level 1 Highway Traffic Noise Prediction Computer Program

摘要

The report documents revisions to the SNAP 1.0 (Simplified Noise Analysis Program) computer program for using the FHWA Highway Traffic Noise Prediction Model. It is also a user's manual for the SNAP 1.1 program, complete with coding sheets and sample problems. SNAP 1.1 contains no acoustical changes from SNAP 1.0, but is easier to use.
