In the 1980s, Transportation Management Associations began to emerge as
public-private partnerships designed to address traffic congestion and
air quality problems in communities throughout the Unites States.
Over 125 TMAs are in operation today throughout the United States, more
than 10 in Colorado. The appeal of a TMA lies in the synergism of
multiple organizations and individuals banding together to address and
accomplish more than any one government agency, employer, developer or
resident could alone. The need for the TMA stems from the realization
that each group has a great influence on transportation and air
quality, and each group has important contributions to improving
mobility and air quality.
The geographic scope of a TMA varies with each organization. Across the
nation, one-third of all TMAs offer services regionwide and one-fifth
serve as a Central Business District. The remainder serve suburban
business parks, residential areas, transportation corridors and tourist
TMA services also vary by organization. The most common services are
rideshare promotions and member advocacy.
