Commute Trip Reduction Policy Framework

The Washington State Legislature passed the Commute Trip Reduction (CTR) Law  in 1991 with goals to improve air quality, reduce traffic congestion, and reduce fuel consumption through employer-based programs that encourage the use of alternatives to driving alone. By creating the CTR program, the Legislature recognized that employers have a significant role and interest in transportation success.

In 2006, the CTR Efficiency Act   (pdf 122 kb) built upon this established employer role and expanded responsibility for program success to local governments who work with employers and make broad economic investment decisions. Local CTR plans and programs are now expected to be integrated with local land use and transportation plans to align policies and investments.

The CTR Board , local jurisdictions, regional transportation planning organizations, transit agencies and employers helped to craft the program's requirements as mandated by the state law, including:

  • RCW 47.04.170 : Designates WSDOT the responsible agency to work with the federal government to support transit, specialized transportation and ridesharing programs.
  • RCW 47.06 : Defines WSDOT's planning role and calls for a statewide transportation policy and multimodal transportation plans and outlines the plan requirements.
  • RCW 70.94.541 : Requires the WSDOT to provide administrative support to the Commute Trip Reduction Board and technical assistance to local jurisdictions.
  • RCW 70.94.547 : Requires all state agencies to aggressively develop substantive programs to reduce commute trips by state employees.
