Anyone who's ever tried to get a new crosswalk in their neighborhood knows how hard it can be just to figure out who to call — never mind how to get whoever's on the other end of the line to listen. And any transportation professional knows how challenging it can be to get that call from a resident, and realize that they don't have the faintest idea of how decisions actually get made on our streets.  But what if cities offered a crash course that got both groups speaking the same language — and in the process, transformed ordinary citizens into effective and well-informed transportation advocates?  Today on The Brake, we welcome Keith Bartholomew of University of Utah and Nathan McNeil of Portland State University, who are hoping to bring the concept of the "Citizen Transportation Academy" to communities across the U.S. Give it a listen, and be sure to check out the beta version of McNeil's curriculum handbook if you're curious about starting a class in your town.
