Definition of Light Rail
“Light Rail is a mode of urban
transportation utilizing predominantly
reserved but not necessarily grade-
separated rights-of-way. Electrically
propelled rail vehicles operate singly or
in trains. LRT provides a wide range of
passenger capabilities and performance
characteristics at moderate costs.”
De Leuw et al., 1976
Rise, Fall, Rise
1917: 45,000 miles of streetcar and
interurban lines
1977: Only eight cities with 300 miles of
lines, but only 125 would be called LRT
(Light rail transit)
2004: 21 cities with close to 600 miles
of lines – most of the addition is LRT
Schumann, J. and F. E. Loetterle (2003)
U.S. “New Starts”
(LRT Lines opened since1980)
San Diego (1981) Denver (1994)
Buffalo (1984) Dallas (1996)
Portland (1986) Salt Lake City
Sacramento (1987) (1999)
San Jose (1987) Jersey City (1999)
Los Angeles (1990) Tacoma (2003)
Baltimore (1992) Houston (2004)
St. Louis (1993) Minneapolis (2004)
Other cities?
Some U.S. urban areas have added
heritage trolley lines, including Tampa
and Memphis. These lines tend to be
tourism-oriented.
A new diesel-powered light rail line
recently opened between Camden and
Trenton, New Jersey (part of the
Philadelphia CMSA).
U.S. „New Starts‟ Process
(since 1984)
Step 1: Alternatives Analysis – Light rail
would be chosen as the L.P.A.
Step 2: Preliminary Engineering
Step 3: Final design
Step 4: Construction begins
FTA rates each step of the project with an
overall “highly recommended,”
“recommended,” or “not recommended”
In order to receive federal funding, New Start
project must be approved by the FTA
Why is Light Rail So Popular?
Supporters say light rail:
Is cost-effective compared with new heavy rail
systems (and no new heavy rail systems have been
proposed recently) +
Responds to urban sprawl, traffic congestion +
Helps revitalize CBD‟s =
Effective transit mode
Result: LRT is an effective added benefit to the
community.
Result of LRT Popularity:
Numerous other metropolitan areas in
the U.S. have light rail transit plans,
proposals, or final designs.
Critics of LRT New Starts:
Costly to build +
High cost operation +
Actual ridership has not met projected
ridership =
Inefficient, ineffective transit mode
Also: LRT “oversold” to community by transit
agencies and supporters
Given that there are both supporters and critics
of LRT, is there a way of measuring its
effectiveness?
The Federal Transit Administration
does!
The FTA performance measures are:
Service efficiency
Cost effectiveness
Service effectiveness
Note: The data come from the transit
agencies; their costs and ridership are the
variables used.
Service efficiency:
Measure:
Operating expense per vehicle revenue
mile
Operating expense per vehicle revenue
hour
Cost effectiveness:
Measure:
Operating expense per passenger mile
Operating expense per unlinked passenger
trip
Service effectiveness:
Measure:
Unlinked passenger trips per vehicle
revenue mile
Unlinked passenger trips per vehicle
revenue hour
What can FTA Performance
Measures allow?
Comparisons among transit modes
since LRT data are presented with bus,
trolley-bus, heavy rail, commuter rail,
demand response, vanpool, automatic
guideways, ferries, etc.
Comparisons among New Start LRT
systems
Mode comparisons (2002 data):
Please note that LRT data include systems in operation before
1980.
Operating expense per vehicle revenue mile:
LRT: $13.00; Bus $6.80; Heavy rail $7.10; Commuter rail $11.60
Operating expense per vehicle revenue hour:
LRT: $199.10; Bus $86.20; Heavy rail $143.00; Commuter rail $366.80
Operating expense per passenger mile:
LRT: $0.50; Bus $0.60; Heavy rail $0.30; Commuter rail $0.30
Operating expense per unlinked trip:
LRT: $2.30; Bus $2.40; Heavy rail $1.60; Commuter rail $7.20
Unlinked passenger trips per vehicle revenue mile:
LRT: 5.6; Bus 2.8; Heavy rail 4.5; Commuter rail 1.6
Unlinked passenger trips per vehicle revenue hour:
LRT: 86.1; Bus 36.1; Heavy rail 90.1; Commuter rail 50.7

** Unlinked passenger trips per vehicle revenue hour.
Problems with data:
Data for this presentation was for only one year;
Data compares only other forms of public transit;
Data for Jersey City (Hudson-Bergen LRT) can‟t be
included because New Jersey Transit combines its
figures with Newark Subway (circa 1935);
Data do not include other measures that may
determine effectiveness of LRT:
Public (and private) support of LRT;
Redevelopment of CBD and other commercial and residential
areas along LRT Route(s)
Effect on private transportation (i.e. how many cars taken
off streets and highways by LRT riders)
Effect on environment (pollution levels, etc.)
Someone else‟s* recent conclusions
regarding LRT new starts and their
relative effectiveness:
“LRT implementation has helped several
communities expand public transit use;
however, it has not resulted in dramatic
changes in the role that public transit plays
in the regional mobility in the respective
communities. While LRT is playing an
important role in expanding opportunities for
transit use, even LRT system development is
a lengthy process with no assurance of
substantial increases in transit ridership.”
