The HHT has been a critical element for accurate analysis of data from some of the sensors on board the DHM van. The capability being created in the van represents the beginning of a paradigm shift in the way states will view and be able to carryout their stewardship of the nation’s highway infrastructure.

Morton Oskard, Structural Research Engineer, Turner-Fairbank Highway Research Center

Under a three-year agreement completed this year, Turner-Fairbank Highway Research Center (TFHRC) scientists learned how to apply Goddard’s Hilbert-Huang Transform technology to analyses of traffic flow data, wind and traffic interaction with bridges, and damage detection in pavement and bridges. These analyses are the basis of TFHRC’s Digital Highway Measurement (DHM) Project and are the first steps in a dramatic shift in the way state departments of transportation will be able to improve the safety and performance of the nation’s highway infrastructure.
