based on three demographic variables: race, income, and limited
English proficiency (LEP). While PBOT recognizes the disparities
that also exist for people with disabilities, available information
about disabilities was not a large enough data set to include
directly. However, the selected demographic variables were
chosen to maintain intersectionality with people with disabilities.
The Equity Matrix data is sourced from the Census, specifically the 2011-2015 American Community Survey (ACS) five-year
estimates. More points are assigned to a census block that has
a higher than citywide average concentration of people of color
and/or people with LEP and/or people below the average for total
household income.
The methodology uses a quintile system where the middle
variable (i.e., value of 3) indicates the citywide average. The

" conglomerate score " used throughout this report is the sum of
points assigned in the race and income categories. Scores for each
category can range from 1 to 5, so the conglomerate score can
range from 2 to 10. Some traffic signals located in industrial areas,
where a census tract is not identified, are shown under an equity
score of zero (0).
Figure 1 illustrates how the equity scores translate to the
traffic signals. For much of our evaluation, we divide the
traffic signals into higher (7-10) and lower (0-6) equity scores.
Fifty-seven percent of traffic signals are in areas with the higher
equity scores and 43 percent are in areas with lower equity scores.
There is a high density of traffic signals in downtown, which is
an area with higher equity scores, but is recognized as a different
environment than other areas of the city.
