WHAT IS TDM?
Transportation Demand Management (TDM) refers to strategies, programs, or policies designed to reduce drive-alone trips and enable the transportation system to function more effectively and efficiently through alternative transportation options.
As the leading transportation advocate, GVF educates commuters on alternatives to driving alone and created this site to be a valuable resource.
