Executive Summary
In July 2005, the Metropolitan Transportation Commission (MTC) adopted
a development policy that supports transit-oriented development (TOD)
in the region. MTC’s TOD policy establishes guidelines for development
near transit stations and in new corridors and ensures that key stakeholders
(both public and private) work cooperatively to create more transit-supportive
areas. In support of the TOD policy, this study was undertaken to characterize
the demographic and travel characteristics of station area residents
– individuals living within close proximity to rail stops and/or
ferry terminals in the region – using an existing Bay Area data
set, the 2000 Bay Area Travel Survey (BATS2000).
Residents surveyed in BATS2000 were grouped into six categories based
on proximity to a rail/ferry station and population density of the area
surrounding the household. The six distance/density categories are:
- Residents within ½ mile of rail and ferry stops,
- Residents between ½ mile and 1 mile of rail and ferry stops,
- Residents
greater than 1 mile from rail and ferry stops in an urban area,
- Residents
greater than 1 mile from rail and ferry stops in a high-suburban
area,
- Residents greater than 1 mile from rail and ferry stops in
a low-suburban area, and
- Residents greater than 1 mile from rail
and ferry stops in a rural area.
Demographic and travel characteristics were then summarized for each
group.
Key Findings
Some of the most interesting findings from the BATS2000
study of station area residents are outlined below.
- People who live close to transit use transit extensively.
People living within ½ mile of a rail or ferry station are four
times as likely to use transit than people living farther than ½
mile from a rail/ferry stop. Non-motorized mode shares are also high
for station area residents who are twice as likely to walk and three
times as likely to bike than residents living more than ½ mile
from a rail/ferry stop.
- People who live and work close to rail/ferry stops
use transit even more extensively.
Individuals living and working within ½ mile of a rail/ferry
stop use transit for 42% of their work commute trips. Individuals who
neither live nor work within ½ mile of a station use transit
for only 4% of their work commute trips.
- San Francisco plays a unique role in transit use in
the Bay Area.
People who live in San Francisco are much more inclined to use transit
than most regional residents, but working in San Francisco also heavily
influences transit use. Interestingly, the highest commute trip transit
share was found for people who work in San Francisco but live elsewhere
and who are close to rail/ferry transit at both trip ends. These
residents use transit for 70% of their commute trips.
- People who live close to transit make as many trips
per day as those who live in the rest of the region, but these residents
have a much higher tendency to use transit, walk, and bike.
- Nearly
one-third of households living within ½ mile of rail/ferry
transit are zero-vehicle households, three times the regional average.
Combining this finding with income distribution for households near
rail and ferry stops suggests that owning no or fewer vehicles is an
individual choice for some people, rather than just as a function of
income.
- People living close to transit are likely to live in
smaller households without children.
Nonetheless, such households still comprise a variety of household
types, with almost 30% of station area households including children,
compared with 42% regionally, and 10% being retired households versus
15% regionally.
- Land use density has an impact on transit use levels,
even beyond one-mile from a station.
Urban residents outside the one-mile distance from rail/ferry are
still twice as likely as suburban residents and about four times
as likely as rural residents to use transit (for work and non-work
trips combined).
- Average weekday daily vehicle miles of travel (VMT)
increases with distance from rail and ferries and decreasing density.
Households within ½ mile of rail stations/ferry produce about
half of the VMT of their suburban and rural counterparts.
- People living close to rail/ferry transit are about
twice as likely to walk for short trips (trips of one mile or less)
than people living farther from transit.
People who live within ½ mile of rail or ferry walk about half
of all their short trips (trips of up to one mile), compared with only
about one quarter of such trips walked by residents outside this range.
Conclusion
The results presented in this work clearly indicate that those living
(and working) close to rail/ferry transit use transit, walk and bike
much more than people living farther from a rail/ferry stop. Whether
being near rail/ferry transit simply allows people who prefer to drive
less that personal choice, or whether it creates a greater interest
in such travel options, this research demonstrates that policies to
support transit-oriented development hold promise as one important tool,
among others, in addressing congestion, transit usage, non-motorized
travel, and air pollution in the Bay Area.
