Fleet Study of Brake Performance and Tire Pressure Sensors

This project is one of several performed under the provisions of Section 5117 of the
Transportation Equity Act for the 21st Century (TEA-21). The primary objective of this project
was to explore the overall effectiveness and customer acceptance of commercial vehicle brake
performance and tire pressure monitoring systems in a field test setting. The work performed
under the project included:
 Selecting brake performance and tire pressure monitoring systems that were
representative of currently available products in the marketplace.
 Arranging for field testing of these systems with a commercial fleet, and in a normal
“everyday” service environment.
 Developing data collection and analysis plans.
 Installing systems on test vehicles.
 Preparing for and conducting the field test.
 Analyzing the data and observationscollected during the field test.
 Developing a report that summarizes the results of the analysis including observations
and conclusions (this document).
