Indicator 1: Average and Reliable Peak Travel Times For Key Commute Routes
Average Peak Travel Times On Ten Key Puget Sound Morning Commutes: Minutes 95% Reliable Travel Times On Ten Key Puget Sound Morning Commutes: Minutes |
Description: Figures show the change in peak travel times along ten key Puget Sound morning commutes between 2002 and 2004. Peak travel times are calculated from weekday averages for the most congested five-minute intervals. Reliable travel time is an estimated travel time with 95 percent certainty (i.e., a commuter will reach their destination within this time 95 percent of the time). Source: |

Indicator 2: Washington State Commute to Work Mode Shares
Washington State Commute to Work Patterns
 |
Description: The figure gives the percentage of commuters who use different modes of travel. Estimates are based on data from the 2000 Census and the American Community Survey. Note that the change in the percentage driving alone between 2000 and 2004 is not statistically significant at the 90 percent confidence level. The change in the percentage working at home is also not statistically significant.

Indicator 3: Percent of Washington Commuters Who Drive Alone
Drive Alone Comparisons: U.S., Washington, Commute Trip Reduction (CTR) Program Worksites (percent of commuters)
 |
Description: Commute Trip Reduction (CTR) site data are from the Washington State Department of Transportation's Commute Trip Reduction Survey. These data represent major employers (with more than 100 full-time workers) in nine counties. The CTR Program covers an estimated 25 percent of commuters in the most populous counties where it operates (Clark, King, Kitsap, Pierce, Snohomiish, Spokane, Thurston, Whatcom, Yakima). U.S. and Washington State estimates for 1990 and 2000 are from the decennial census; data for 2001 to 2005 are from the American Community Survey.

Indicator 4: Distribution of Population and Employment Growth Among Central Puget Sound Counties
Population and Employment Growth Shares: 1995-2003
 |
Description: Estimates refer only to the four counties in the Central Puget Sound Region (King, Kitsap, Pierce, and Snohomish). Growth shares represent the county's share of total growth in the region. For example, King County accounted for 69 percent of the employment growth in the region but only 42 percent of the population growth over this period. Source: Puget Sound Regional Council
