2.2 Commute Mode Split

To analyze how Washington County employees get to work, Figure 2-3 compares commute
mode shares for employees who:
 Live and work in Washington County
 Live in Washington County and work outside of the County
 Live outside Washington County and work in Washington County
 Live outside Washington County and work outside Washington County
Single-occupancy vehicle (SOV) makes up the largest portion of mode share regardless of home
or work location. Washington County employees are more likely to take transit to work if they
live outside the County (4.4 percent) rather than employees who live and work in the County
(3.3 percent). The highest percentage of people who walk to work live and work within
Washington County (3.9 percent). Ten percent of both Washington County employees who live
in the County and live outside of the County carpool to work. Similarly, approximately 10
percent of Washington County residents who work outside the County carpool to work.
Bicycling makes up the smallest percentage of the commute mode split.
