Plan Your Commute - 95% Reliable Travel Times


Calculate Your Commute - This feature uses travel time data to provide a reasonable approximation of the "worst case" travel time scenario. By allowing for the calculated travel time, commuters can expect to arrive at the end of the route, on time, 19 out of 20 working days a month (95 percent of trips). These travel times are based on weekday travel time data from the hours of 6:00 AM to 7:00 PM.

Use WSDOT's 95% Reliable Travel Times commute calculator. This feature accesses travel time data to provide a reasonable approximation of the "worst case" travel time scenario during weekdays. It's easy to use. Enter:

  • Where you are starting from,
  • Where you are going,
  • What time you need to get there.

The calculator will show you how long it will take to make the trip and when you will need to leave to arrive at your destination on time.
