Rails-to-Trails Conservancy's Transportation Alternatives Data Exchange (TrADE) is the nation’s go-to transportation funding data source for trails and active transportation, tracking Transportation Alternatives (TA) spending for tens of thousands of projects. Since the inception of Transportation Enhancements in 1991, renamed Transportation Alternatives in 2012, RTC has monitored how these dedicated funds have been invested in order to help stakeholders at the federal, state, and local level better understand and implement this program. From 1996 to 2013, TrADE operated as the National Transportation Enhancements Clearinghouse, as a partnership between RTC and the Federal Highway Administration.
