Highlights and Benefits from Scans

The impact of the International Technology Scanning Program on U.S. policy and technology has been dramatic. Its impact can be seen in areas ranging from the use of stone matrix asphalt surfaces in Maryland and design-build contracting in Utah to the application of lane rental techniques in Minnesota and right-of-way procurement practices in Florida.

Benefits can be grouped into four broad areas. The first area is cost savings attributed directly to the application of technologies identified by scan teams. The second is the filling of FHWA and State department of transportation (DOT) "tool boxes" with ideas generated from scans. The third is the impact of scans in redirecting programs and policies and validating current U.S. practices. The last is benefits that could be incurred if the technology or policy continues to evolve.

The following are highlights of known benefits resulting from the momentum provided by the scan program. It would be an overstatement to say that all of these benefits were identified solely through scanning studies. Rather, it would be more accurate to say that scanning studies play a vital role in initial identification and forging of strong working relationships with our international partners and providing the stimulus for the implementation of ideas and emerging technologies.
