User's Manual for the Noise 1 Area Computer Program for Transportation Noise Prediction: Report Under Project Entitled "Area Computer Model for Transportation Noise Prediction: Phase 1: Adaptation of MICNOISE"

Report No: 75-R32

Published in 1975

About the report:

It was found that the coordinates of the highways required for Noise 1 could be supplied on punched cards by the Photogrammetry Section of the Department. In preparing data for contour plotting, it was found advisable to divide the area into sectors, with each sector being surrounded by the edges of roads or by internal boundaries. In this manner, the singular lines that would be present along the roads were avoided. The XYNETICS contouring program was used. Unfortunately, the quality of the contours produced was so low that it was necessary to post the calculated L10 contours by hand. In this Phase 1 version of the area computer model, vertical terrain corrections were omitted, pending a better understanding of computing times required.
