CHALLENGE
Displacement in inner-cities has pushed former
residents to the suburbs, contributing to the
suburbanization of poverty. However, transit is not
walkable for many in the sprawl. It is neither cost-
effective nor time-effective for transit authorities to
extend fixed-line bus service into areas outside of
major road arteries. [2]
SOLUTION
Public subsidies for ride-shares can be an alternative
solution to extending the reach of transit.
APPROACH: A THEORETICAL PILOT FOR SACRAMENTO RT
• Defining boundaries: Areas not in the walk-shed from
Regional Transit (RT) light-rail stops and corridors with
frequent bus service, but within RT’s service area. (F.1.)
• Determining eligibility: Identify ‘disadvantaged’
communities not within the transit walk-shed. (F.1.)
• Setting the subsidy: A $3 subsidy would bring the
minimum cost of a ride-share to $2.75 per user.
Subsidies can be applied for first-and-last mile
connections to transit, or be combined among users
to fund carpools.
FINDINGS
• A 1% reduction in RT’s revenue bus service yields a
cost savings of $830,440, which is sufficient to provide
for 276,813 rides. This total would allow RT to offer $3
subsidies for a year’s worth of commutes —480 rides—
for 576 individuals. [3]
• Carpools can cut costs for each user in half.
• Results from a hypothetical commute under the pilot
program from Upper Land Park, a disadvantaged tract
within the highest average percentile, to the South
Sacramento Industrial Area: (F.2.)
• Current Transit: 78 minutes. $2.75 fare card.
• Transit and ride-share: 42% reduction in commute
time. 92% increase in cost to user.
• Carpool ride-share only: 79% reduction in commute
time. 1.09% increase in cost to user.
• Compared to RT’s current operating expense of $5.70
per unlinked bus passenger trip, a $3 ride-share subsidy
per participant will yield a 47% decrease in costs. [3]
POLICY SUGGESTIONS
• Transit authorities should design pilot programs for ride-
share subsidies.
• To minimize vehicle miles traveled (VMT) and costs,
shared rides through carpools should be prioritized.
• Investments in fixed-rail lines to suburbs, and
pedestrian and bicycle infrastructure —especially in
disadvantaged communities— should remain the
priority for budgets.
• Governments should explore redistributive taxes
imposed on premium ride-share tiers (UberLux, Lyft
Premier) to fund transportation equity programs.
• Utilize funding opportunities from the Federal Transit
Authority’s (FTA) Mobility-on-Demand (MOD) Sandbox
program.

‘disadvantaged’ tracts [defined
as at or above the local mean
CalEnviroScreen score of 28]
which are outside of the transit
walk-shed of 0.5 mile from rail,
0.25 mile from bus [filter
applied: bus lines with < 30
min. service frequency]. [1]
