Transportation Demand Management Director

Scott Mullen joined the ABC team as Transportation Demand Management Director in summer 2020. He is responsible for managing multiple Transportation Management Associations (TMAs) that collectively serve over 100 member organizations as well as leading policy research and advocacy related to TDM issues such as municipal regulations, zoning, employer transportation benefits, and transit fare policy. His goal is to build innovative, sustainable TDM policies of the future, now.

For the last two decades, Mully has focused on promoting and delivering solutions that help individuals and institutions ‘think outside the car’. His approach to modeshift has spanned the fields of journalism, startup operations, business development, advocacy, strategy, and government relations. A shared economy pioneer, Mully was an early employee at several groundbreaking companies and has had a front row seat in the formation and growth of three transportation sectors: carsharing at Zipcar, bikesharing at Hubway (now BlueBike), and micromobility at Lime. 

Mully holds a B.A. in Philosophy from Merrimack College and feeds his love of learning with frequent courses through edX.
