what we do


Designing sustainable transportation solutions for livable communities

Transit systems improve livability, provide affordable mobility, manage congestion, and lower energy use and greenhouse gas emissions. From initial system planning and securing environmental approvals, through design and assistance with operations, Parametrix partners with agencies on all types of transit systems—commuter rail, light rail, heavy rail, bus rapid transit, streetcar, and ferry systems. Our staff regularly coordinates with FTA and has comprehensive knowledge of the New Starts program.
