Special Populations
Transit-using At least one trip by transit on travel day
Low-income Households falling below the 2005 poverty line Census definition using size and income
Non-motorized Walk or bike to work or school on travel day
Students Report at least one trip to a university campus on
travel day

Why Special Populations
Regional Goals “Develop a regional transportation network that
improves quality of life and the environment” “Convenient, accessible, and affordable public
transportation system…” “A pedestrian and bicycle system that: provides
an alternative means of transportation; allows greater access to public transit…”
“A transportation plan that is integrated with local land use plans and development policies.”
“A multi-modal transportation system which provides access and mobility to all residents, while protecting the natural environment, cultural resources, and social systems.”

Approach to Capture Populations
US Census Data used to ID tracts Journey to Work Data: Transit-using and Non-
motorized Population Data: Low-income SF4 Table PCT63: Students
List of tracts fitting profile developed Tracts with highest likelihood identified Sample generated using listed records only

Bottom Line
The number of samples was ok, but not high enough without the targeted sample.
