Congestion
Vehicular Congestion
City role: indirect
Vehicular congestion is measured in two ways.  It is expressed as the average delay (in minutes) incurred during a one-mile trip on principal, minor, and collector arterials in Redmond during the p.m. peak (5 p.m.-6 p.m.). This includes trips on uncongested streets and in non-peak directions, so the citywide average is lower than the delays that travelers would experience along the city’s most congested segments of roadway.

Congestion is also measured by direct traffic counts along traffic screenlines, and expressed as the percent change from the baseline year.

Both the 2030 and long-term aspirational targets for delay acknowledge that delay for roadways users will continue to grow as long as the number of jobs and housing units increases in Redmond. The 2030 target is the result of travel demand forecast model projections for 2030, which take into account land use changes, the transportation improvements included in the TFP, and changes in mode share and trip length.

Direct vehicle counts measure raw traffic volumes on key Redmond arterials.  In 1996 the total number of vehicles counted at all screenlines was about 903,000.  In 2012 (latest available) that figure was 843,000 - 6.6 percent lower than in 1996.  The most recent traffic volume peak was in 2006, at 983,000 vehicles.
