Our vision of America's public and community transportation future -- the cause that we serve -- is based upon fundamental values that are as old as the nation itself. Freedom, independence, dignity and choice are as much at the heart of the debate for building an accessible society as they have been in building a free society. There is never an end to the work to create a free society, and there will never be an end to our work to build a more mobile society. Both of these noble pursuits remain great works in progress.


It is our mission to develop, improve and promote sustainable intermodal mobility combining innovative rail, waterway, road, air and maritime transport solutions. We aim at using every mode of transport in the most optimal way by improving their links with each other (also called “co-modality”).
