The Truck Weight Enforcement Effectiveness Tool (TWEET) is a software application developed by TRC under NCHRP Project 20-34 that performs sophisticated analysis on WIM data and presents information about the results in an easy-to-understand manner. With TWEET you can process WIM data files in almost any format, and then see results including:
  • Numbers and percentages of gross- and axle-weight violations
  • Breakdown of violations by vehicle type, day of week, time, etc.
  • Aggregate effects of weight violations on pavement life
  • Levels of statistical confidence of the program's calculated output
And all you need to run TWEET is a personal computer with Microsoft Windows 95 or higher.

TWEET is free available for download from this site. To download a copy of the latest version of TWEET, please visit our download page.
