Commute Trip Reduction Program

In 1991, the State of Washington adopted its Commute Trip Reduction (CTR) law. The law's intent is to reduce traffic congestion and air pollution by shifting drive-alone commutes to other modes. Today, more than 1,000 worksites take part in the CTR program statewide. One quarter of those sites are in Seattle. The program is well known nationally as an example of impactful Transportation Demand Management (TDM).

Seattle's CTR program is a partnership between the State, City, and Seattle employers. The business-oriented program provides education, events, communications, and data insights to support commuters, businesses, and the environment through transportation choices. As a result, the drive alone rate has decreased. Over two-thirds of CTR affected commuters choose transit, walking, carpooling, bicycling, or telecommuting.
