A draft American National Standards Institute (ANSI) standard on “Methods for Measuring the Vibratory Response of the Ground” is nearing completion for review. This standard is being developed in parallel with a separate draft standard on “Methods for the Prediction of Ground Vibration from Rail Transportation Systems.” The intent of both documents is to standardize methods that were initially developed more than 30 years ago and adopted by the Federal Transit Administration. This paper will outline the topics in the draft standard, the measurement, and analysis techniques typically associated with the methods described, and how the draft standard relates to existing standards pertaining to measuring transfer mobility.
