The U.S. Department of Transportation’s Bureau of Transportation Statistics’ (BTS) initial National Transportation Noise Map shows that more than 97 percent of the U.S. population has the potential to be exposed to noise from aviation and Interstate highways at levels below 50 decibels.

The Bureau of Transportation Statistics (BTS) released a newly updated double-sided wall map, Transportation Geography of the United States. The front of this map features a reference map of select U.S. transportation infrastructure and connections, including the National Highway System (NHS), class I railroads, airports with at least 750,000 enplanements, major ports with a commodity tonnage total of 10 million or more, and border crossings on the NHS.
