Center City Commuter Mode Split Report, Seattle, Washington, February 2016

  • Date Enacted: Feb 1, 2017
  • Dates given are approximate.


This report produced by Commute Seattle, a non-profit Transportation Management Association partnership, is the product of a biennial survey of the mode choices of commuters in the central business district. The survey found that transit trip share increased by 5%, while single occupancy vehicle trip share decreased by 5%. Non-motorized and ride-share trip shares remained constant. The survey was particularly concerned with the possible effects of the Washington Commute Trip Reduction (CTR) law (1991) and CTR Efficiency Act (2006), which offers transportation demand management (TDM) benefits to businesses with at least 100 employees.

Commute Seattle hosts pages for both the report and infographics drawn from their findings.
