3.2.2 Last Mile Travel Options Propensity

Three factors were considered for the employee last mile travel options propensity: low wage
jobs and age of employees (young adults and older adults). Examining where these groups work
may help determine suitable locations for last mile projects, programs and outreach to partners.
Data for these maps was taken from the Census Transportation Planning Products (CTPP), a data
source for transportation compiled by American Association of State Highway and
Transportation Officials (AASHTO). The following maps show the work location of Washington
County employees, by density, who are considered low-income, followed by the employee
travel options propensity map and employment access to transit:
 Figure 3-6 Low-Income Employees: Low-income employees are concentrated in the
cities with the most employees, Beaverton, Hillsboro, Tigard, and Tualatin. Beaverton
has the most low-income employees, primarily in the north western portion of the city.
 Figure 3-7 Employee Travel Options Propensity: With a variety of frequent transit options
available in Washington County, many employment sites are within one mile of frequent
transit service. Travel options propensity for employees is concentrated along existing transit
routes, including WES, MAX, and frequent and local bus service. The highest number of
employment sites within one mile of frequent transit service are located in Hillsboro near
the MAX Blue Line. The cities of Beaverton, Hillsboro, and Tigard have the highest propensity for
last mile travel options.
