The AAMA Traffic Noise Model - A Better Approach 951336

Currently there are no community noise computer programs commonly in use in the United States dedicated to the modeling of interrupted flow. Constant speed programs (such as STAMINA 2.0) have been used with modified input to predict noise levels at intersections, but they cannot directly simulate traffic signal operation, actual deceleration and acceleration of vehicles, or queues of vehicles at signals. Noise prediction procedures for intersections can be improved by simulating actual intersection movements. The American Automobile Manufacturers Association has produced a model that not only models continuous flow (Constant Speed Traffic program - CST), but also allows modeling of interrupted flow (Variable Speed Traffic program - VST). This model has been updated to improve user friendliness and accuracy and is discussed in this paper.
