by Jason
McConachy and Robert E. Spicher
This article provides an update on the work and findings of the National
Highway Research and Technology Partnership, an initiative in which
160 organizations participated to assess the needs of highway research
and technology.
Managing
Traffic Flow Through Signal Timing
by S.
Lawrence Paulson
Traffic signal management is one of the most cost-effective ways to
keep traffic moving smoothly and to make streets safer. Efficient
traffic signal control systems improve air quality and reduce fuel
consumption, reduce traffic congestion, reduce the number of crashes,
reduce red-light running, and postpone or eliminate the need to construct
additional road capacity.
Lessons
Learned About Bridges From Earthquake in Taiwan
by Wen-Huei
(Phillip) Yen
A U.S.-Taiwanese team visited 10 bridge sites in Taiwan to evaluate
Taiwanese bridge performance during the devastating Chi-chi Earthquake,
which occurred on Sept. 21, 1999. The earthquake measured 7.6 on the
moment magnitude scale, and more than 2,400 lives were lost as a result
of the earthquake.
An
Olympic Event: Handling Transportation During the Olympics
by John
R. Njord
Studying all relevant information, including the lessons learned
from previous Olympic Games, the Utah Department of Transportation
(UDOT) created and implemented an effective travel demand program
to handle the anticipated increase in traffic during the Winter Olympics
in February 2002. UDOT's goals are to get the athletes and spectators
to Olympic venues in an efficient and timely manner and to reduce
background traffic by 20 percent.
A
Legacy in Art in a New Exhibition
by George
Austin Hay
The collection of Carl Rakeman's 109 original paintings documenting
the history of highway transportation in America
finds a new home at the Texas Transportation Institute. From 1921
to 1952, Rakeman painted this extraordinary pictorial record of the
development of travel in this nation. These paintings cover American
travel from frontier Indian trails and pre-colonial times to modern
highways.
FHWA
and Nevada DOT Create a Wetland in Nevada
by D.
Gail Bellenger
It may be surprising to some, but even Nevada with its desert climate
has wetlands. The Federal Highway Administration (FHWA) and the Nevada
Department of Transportation created a large wetlands area adjacent
to the scenic Washoe Lake to offset the unavoidable loss of wetlands
areas as a result of highway construction and maintenance projects
in and around Reno and Carson City.
It's
the Ride That Count$
by Rick
Boeger and Roberta J. Crowe
The Maricopa County (Ariz.) Department of Transportation in Phoenix
has put in place a program that makes contractors on roadway paving
projects put their money where the ride is. Contractors, under this
incentive program, can earn as much as an additional 10 percent of
total paving costs in incentive bonuses by exceeding the preset standard
for smoothness. Conversely, contractors are hit in the pocketbook
if they don't meet the standard.
