Management and Administration
Secretary Mineta Applauds Innovative Financing
For S.R. 125 South Project
U.S. Transportation Secretary Norman Y. Mineta recently
joined State and local officials at a historic groundbreaking
ceremony for the southernmost segment of a
construction project on State Route (S.R.) 125 South in
southern California. A key element in enhancing the
surface transportation system in the growing San Diego
area, the project involves developing and operating a toll
road to reduce congestion and pollution.
Federal loan assistance was essential to finance the
road, providing flexibility in the repayment structure
during the project’s ramp-up period. The Federal government
executed a $140 million loan for the project under
an innovative financing program established by the
Transportation Infrastructure Finance and Innovation Act
of 1998 (TIFIA). The terms negotiated for the loan
provide the first example of a partnership acceptable to
both TIFIA and a private sector investor.
TIFIA provides Federal credit assistance to major
transportation infrastructure projects that address critical
national needs, such as intermodal facilities, border
crossing infrastructure, highway trade corridors, and
transit and passenger rail facilities with regional and
national benefits. Although the S.R. 125 project satisfies
loan eligibility criteria by falling into the major highway
category, funds also may be allocated under the categories
of bridges, intercity bus and rail systems, and transit
facilities and vehicles.
By enabling USDOT to provide credit assistance
(rather than grants) to private sponsors, TIFIA facilitates
the accessing of private capital markets for financing
major transportation projects.
Roadway Safety Awards Recognize
Programs in 13 States
On behalf of the Federal Highway Administration
(FHWA) and the Roadway Safety Foundation, FHWA
Administrator Mary E. Peters recently recognized
projects in 13 States with 2003 National Highway Safety Awards. The awards highlight initiatives that save lives by
improving roadway design, operations, and planning.
Each year, FHWA offers the awards in the categories of
infrastructure improvements; operational improvements;
and program planning, development, and evaluation.
Highway programs in Arizona, California, Colorado,
Florida, Iowa, Maine, Maryland, New York, Oklahoma,
South Carolina, and Washington received awards. A
regional traffic system with roadway sections in Kentucky
and Indiana also received an award. The winners
were selected from more than 130 entries, and included
six State transportation departments, a regional transportation
consortium, two counties, two cities, and a State
police agency.
FHWA recognized some projects for their capacity to
reduce crashes, while others were honored for their
contributions to pedestrian safety and environmental
preservation. The California Department of Transportation,
for example, improved the Angeles Crest Highway
(S.R. 2) corridor by reducing the speed limit, requiring
daytime headlights in one section, instituting a doublefine
zone, and installing a guardrail upgrade—all of
which led to a marked reduction in crashes. Montgomery
County, MD, developed design standards that include
provisions for sidewalks and bike paths on residential
streets and collector roads to ensure the safety of
nonmotorized traffic.

Innovative Replacement for a Historic
Bridge on U.S. 2
As part of a $4 million project, the Washington State
Department of Transportation (WSDOT) replaced a 1935
steel truss bridge with an innovative, high-performance
weathering steel bridge. The first of its kind in the State
to use the high-performance steel, the new bridge is
more environmentally sensitive than its outdated predecessor.
The structure provides more clearance for debris
flowing under the bridge during floods and eliminates
the need for supportive piers in the waterway, thereby
enhancing fish habitats. In addition, biofiltration swales
built into the structure will reduce heavy metals in stormwater
runoff; the old bridge had no treatment provisions.
The new bridge is more efficient and economical,
requiring less maintenance and offering expanded traffic
flow. Built to current seismic standards with no overhead
truss, the bridge also eliminates clearance restrictions. Because the bridge’s natural corrosion is designed to
create a dense, protective barrier for the structure, WSDOT
managers will not need to paint the bridge as often.

To accommodate the larger, more technically sophisticated
structure, WSDOT designed the bridge to provide
1.8-meter (6-foot) shoulders and adapted the nearby
roadway to ensure the safety of bicyclists and drivers.
WSDOT graded and paved U.S. 2 to provide greater sight
distances and establish a roadway geometry suited to the
97 kilometers per hour (60 miles per hour) speed limit. The bridge opened to traffic on June 3, 2003.
Washington State DOT
Research Facility to Design Fish-Friendly Culverts
A Federal report in 2001 found that thousands of
culverts on Federal lands are too high or steep, disrupting
migrating fish. A new research facility adjacent to the
Skookumchuck River near Tenino, WA, will serve as a
test bed for designing fish-friendly culverts—the metal or
cement pipes that funnel water beneath roads. According
to the Washington Department of Fish and Wildlife,
33,000 culverts around the State need to be replaced or
repaired to enable fish to pass through safely. WSDOT
and other agencies and jurisdictions expect to retrofit
thousands of culverts during the next few years.
Operated by the Washington Department of Fish and
Wildlife, the full-scale facility will provide the scientifically
sound information to help develop more effective
designs for new or retrofitted culvert installations. The
test bed, initiated by WSDOT and other State transportation
agencies, will consist of two large steel tanks—one
upstream, one downstream—that cradle a 12-meter (40-
foot) corrugated steel culvert whose slope rises or falls
to mimic various existing culverts. Facility operators also
can adjust bed configurations, such as baffles, ladders,
and other retrofits, to determine which techniques make
it easier for local fish, including several species of
salmon, to pass under highways and other roadways.
“Investing in this system provides WSDOT with
improved scientific data to ensure that we’re spending
money on solutions that will work to provide long-term
benefits to our environment,” says John Peterson of
WSDOT’s environmental services office.
Washington State DOT
California to Host Conference on
Orthotropic Bridges
Recent structural improvements and increasing fatigue
strengths have assured engineers that orthotropic (solid
steel plate) bridge decks can be expected to have long
service lives. As a result, State highway agencies now are
using orthotropic decks for major projects.
To educate the engineering community on new
developments in orthotropic bridges, the American
Society of Civil Engineers (ASCE), USDOT, and eight
other sponsors are compiling a 7-day technical program
encompassing classes, a conference, and tours of
orthotropic bridges in northern California.

Scheduled for August 23–29, 2004, the conference
will draw delegates from Asia, Europe, the United States,
and elsewhere. Papers will cover a variety of topics,
including design, construction, fabrication, wearing
surfaces, maintenance, research, and materials. Tours will
visit nine orthotropic bridges in the San Francisco area.
Event organizers invite members of the engineering
community to volunteer as chairpersons or members
of planning-related committees to help with organization,
financial components, technical aspects, publicity,
and tours.

National Research Center Marks New Era
In Pavement Preservation
In late 2003, pavement preservation in the United States
entered a new era with the dedication of the new
National Center for Pavement Preservation (NCPP) at
Michigan State University. A partnership created by the
Foundation for Pavement Preservation, FHWA, and the
university, NCPP will coordinate collaborative efforts
among government, industry, and academia.
Pavement preservation is a planned strategy for
treating pavements at the optimum time to maximize
their useful life, enhancing longevity while lowering
lifetime costs. The key to successful preservation is
applying the right treatment to the right pavement at the
right time. Treatments must be selected carefully and
applied when the pavement is still in good condition
(that is, with no structural damage).
According to the center’s Web site (www.pavementpreservation.org), the American Association of
State Highway and Transportation Officials (AASHTO)
estimates an annual cost of $92 billion to maintain
existing highways over the next 5 years. Making significant
improvements could cost as much as $125 billion
annually. NCPP advocates improving pavement conditions
in a cost-effective way.
In addition to acting as an advocacy group, NCPP also
offers several services, including training, outreach, and
research management. The center plans to cooperate
with the university to create undergraduate and graduate
courses and offer continuing education units as well. NCPP also will provide private clients with custom designed
training sessions onsite or at alternate locations. Further, the center will facilitate research projects in
conjunction with other academic institutions and the
private sector.

Wisconsin Uses Pavement Markings
To Reduce Speed
In October 2003, the American Automobile Association
in Wisconsin sponsored a media event to showcase a
successful experimental technique for reducing speed on
the Mitchell Interchange of I–94, I–894, and I–43 in
Milwaukee, WI. The experiment uses converging chevrons
on the pavement and special edgeline markings to
encourage drivers to reduce their speeds as they approach
a tight ramp. The Milwaukee site is the only
installation with this specific pavement-marking pattern
in the country, but the idea originated in Japan, where
several experiments also have been successful.
The Wisconsin Department of Transportation
(WisDOT) installed the markings in 1999 as part of a
freeway resurfacing project. WisDOT selected the test
ramp for the installation based on traffic volumes and
roadway geometry. The ramp had a history of rollovers
involving large trucks, causing long road closures. After placing four speed detectors at and near the test ramp
and setting up a comparison ramp without chevrons,
WisDOT researchers could measure the effectiveness of
the installation in reducing speed.
After the installation in May 1999, mean speeds
dropped significantly at three of the four detectors, and
as much as 24 km/h (15 mph) at one of the detectors.
Total crashes on the test ramp dropped from 14 in the
preinstallation period to only 8 postinstallation. Although
installing chevron patterns on this particular test ramp
appeared to result in notable speed reductions, WisDOT
researchers suggest that further research is necessary
before any definitive statements can be made about
overall efficacy.

Federal Agencies Sponsor National Trails Day
National Trails Day, organized by the American Hiking
Society, will take place this year on June 5, 2004. Held
annually on the first Saturday of June, the celebration
increases public awareness and support for trails used
for activities ranging from hiking and cycling to
snowmobiling. This year’s theme, “Trails and Health … A Natural Connection,” emphasizes the links between
trails, leisure, and exercise.
FHWA’s Federal-Aid Highway Program, the largest
single funding source for trails in the Nation, is one of
several Federal sponsors, including the U.S. Department
of Agriculture’s Forest Service, the U.S. National Park
Service, and the U.S. Department of the Interior’s Bureau
of Land Management.

“Trails were the beginning of the Nation’s highway
system, and they benefit both transportation and recreation
today,” says Christopher Douwes, manager of the
recreational trails program at FHWA. “Our trail infrastructure
can improve the transportation network by connecting
neighborhoods, parks, schools, commercial areas, and
transportation facilities, and help people live active and
healthy lives.”
Planned events across the country include trail
openings and ribbon-cuttings, commemorative walks and
bike rides, cleanups and new trail constructions.

Contraflow Project to Ease Congestion in Hawaii
Recently, the Hawaii Department of Transportation
(HDOT) launched a 4-month, $1 million demonstration
project to create a morning contraflow lane on Nimitz
Highway into Honolulu, HI. The road typically carries
more than 3,700 cars (including many carpools) per
hour during peak hours. By borrowing a westbound
lane, the project provides an extra high-occupancy
vehicle (HOV) lane for those commuting into Honolulu.
This adaptation creates a 3.2-kilometer (2-mile) extension of the HOV lane on the H–1 Freeway, which currently
ends at the Keehi Interchange, all the way to Pacific
Street. The lane operates during the morning peak
commute period from 5:30 to 8:30 a.m.
Since the 1950s, Nimitz Highway has been considered
one of the most congested roadways on the island of
Oahu. Although officials discussed the contraflow plan
for more than a decade, area businesses and residents
feared it would disrupt commerce and street traffic.
HDOT conducted extensive public outreach, however,
and a followup survey of 165 area residents and businesses
revealed that 75 percent of respondents were in
favor of or had no problem with the project.
To help ensure pedestrian safety, HDOT posted signs
advising pedestrians to “look both ways” before crossing
the contraflow lane. Supplemental warnings will be
painted on the sidewalks, and police officers will be
hired to assist schoolchildren crossing the highway. Left
turns, with the exception of one intersection, will be
prohibited throughout the contraflow area.
According to State Transportation Director Rodney
Haraga, if the lane proves successful, Hawaii may build
an elevated two-lane road along the corridor, which
would enable traffic managers to reverse the contraflow
lanes in the afternoon.

New Database Tracks ITS Legislation
As part of a cooperative agreement with FHWA, the
National Conference of State Legislatures tracks State
efforts to use technology and intelligent transportation
systems (ITS) to improve the safety and efficiency of
surface transportation. The new Intelligent Transportation
Systems State Legislation Database tracks current ITS
legislation in the States, providing information on bill
numbers, summaries, and information on bill status.
Users can search the database by the bill’s year, status
(active or inactive), sponsor, and the most recent date of
action. Constituents also can search by the State in
which the bill originated, or simply use a keyword to
find the appropriate bill.
The National Conference of State Legislatures’ transportation
program offers information, research, legislative
data, and referral assistance on more than 350 topics.
The leading transportation issue areas include distracted
driving, drunk driving, hazardous materials, ITS technologies,
and rail and traffic safety.
To search the database, visit www.ncsl.org/programs
/esnr/its.cfm.
Closing Roads during Construction Enhances
Safety and Efficiency
FHWA recently published a brochure on full road
closure, an approach to roadway construction that
entails closing one or both directions of a road and
detouring traffic. Shorter Duration, Safer Work Zones,
More Satisfied Travelers: Successful Applications of Full
Road Closure in Work Zones (FHWA-OP-03-086) is the
first product of a study that assessed six field applications
that used the approach. Full road closure eliminates worker-traffic interaction and provides workers access to
the entire roadway section during construction, potentially
improving efficiency and safety and reducing the
duration of work.
The brochure provides several case studies detailing
significant benefits garnered from projects that used full
road closure. Near Detroit, MI, for example, closing the
Lodge Freeway during construction reduced project
duration by 71 percent. In Portland, OR, the Oregon
DOT used two full closures (one direction at a time) to
complete a project within 10 days, instead of 32 nights
of work using partial closure, and reduced the overall
cost of the project by $100,000. Oregon DOT engineers
estimate that they could have cut the total project cost
of $2.5 million in half if they had specified the use of
full closure in the original contract.
The Ohio DOT is using full closure to rehabilitate a
major route through downtown Columbus and expects
to save up to $10 million by completion. “Under the
appropriate conditions,” says Gordon Proctor, director of
the Ohio DOT, “a full closure can be an effective way to
complete projects faster and improve safety for highway
workers and motorists.”

Proceedings Available from Conference
On Congestion
Final proceedings now are available from the “Traffic
Congestion: Issues and Options” conference, held in
Washington, DC, in June 2003. The conference, cosponsored
by the Institute of Transportation Studies at the
University of California, Los Angeles (UCLA) and the UCLA
Extension Public Policy Program, examined the causes
and consequences of traffic congestion in the United
States and various strategies for tackling the problem.
Although attendees concluded that there is no “silver
bullet” for solving congestion, the report contributes to
more informed decisionmaking in the reauthorization of
Federal surface transportation legislation.
Organized into 11 sections, the report addresses many
aspects of traffic congestion, ranging from environmental
impacts to potential solutions. A section on the Federal
role, for example, describes how increasing population
pressures on the Nation’s roadways challenge the
shrinking financial capacities of local roadway management
groups. A section on air quality discusses the
respective benefits of traffic flow-based solutions and
technology-based solutions to the problem of air pollution.
A chapter on market-oriented solutions explores the
policy of discouraging congestion by raising toll prices
for rush hour traffic.

FHWA Reports on Traveler Information
Systems in Europe
The FHWA Office of Policy recently released a report
summarizing the findings from a scan tour of traveler information systems in Europe. Based on data gathered
during a tour conducted in October and November
2002, Traveler Information Systems in Europe (FHWAPL-
03-005) illustrates innovations in informational
products for tourists and travelers.
The scan team identified eight cities in Europe that
operate well-established traveler information products
and services that reflect all transportation modes. A
panel, cosponsored by FHWA and the American Association
of State Highway and Transportation Officials,
reviewed and documented the practices, policies,
strategies, and technological innovations and evaluated
them for potential application in the United States. The
timing for the tour also enabled the team to examine
European practices that could be applied specifically to
implementing the 511 telephone number for traveler
information services.
The report reveals several key findings regarding cost
recovery models, new technologies and quality-control
measures, and the information content provided under
European systems. The report also reviews the national
consistency standards and legal issues regarding traveler
information systems in various countries.
The panel issued several recommendations, including
applying additional resources to close the data gap and
improving the quality of traveler information. The panel
also recommended incorporating the principle of
traveler information into agency and corporate missions.
The report is available at http://international.fhwa.dot.gov/travelinfo/index.htm.
Iowa Introduces Initiative to Reduce
Deer-Vehicle Crashes
Approximately 7,400 deer-vehicle crashes are reported
every year in Iowa, making up 12 percent of the State’s
total crashes. The Iowa Department of Natural Resources
estimates that the actual number of deer-vehicle crashes is around 12,000. And a number of
additional run-off-the-road crashes occur when drivers
intentionally swerve to avoid hitting deer or other
animals in the roadway. Each year, these crashes result
in $13 million in vehicle damage, 600 injuries, and 2
fatalities. Because of a significant increase in the State’s
deer population (which has doubled since 1985) and
the growing number of miles driven on Iowa roadways
each year, the potential for deer-vehicle crashes continues
to rise.
Iowa is taking a two-pronged approach to reduce
deer-vehicle crashes and improve driver safety. The first
strategy is to decrease the animal population by increasing
the number of deer that can be taken by hunters.
The second is launching a public information and
education campaign featuring the message: “Don’t Veer
for Deer.”
The campaign features a Web site and a brochure
instructing drivers on how to reduce their risk for deer
crashes. Motorists are discouraged from veering into
oncoming traffic as well as off the roadway. Tips include
watching for deer near wooded areas and waterways,
and expecting deer to travel in groups. The brochure advises that “striking the animal is often the safest action”
and tells motorists to brake firmly, steer to maintain
control, and stop as safely as possible.

ITS Arizona Honors Alan Hansen with
Member of the Year Award
In 2003, ITS Arizona—a State chapter of ITS America—
celebrated its ninth anniversary and initiated a new
award for member of the year. Looking back over the
past 10 years, the board of directors for ITS Arizona
considered individuals who actively supported the
organization from the beginning. This year’s award went
to Alan Hansen, engineering technology coordinator for
the FHWA Division Office in Arizona.
Hansen not only was a founding member of the
chapter and served on the original board of directors,
but also he contributed to the group’s original charter
and was active on several committees. Most recently, he
helped plan a special meeting on homeland security.
Hansen edited the group’s newsletter for nearly 3 years,
during which time he also wrote eight articles. In
addition, he presented at several conferences and annual
meetings.
“From one standpoint it was a great honor to be
recognized outside of FHWA,” Hansen says. “On the other
hand, it made me realize that ITS Arizona is truly a group
of individuals who work together to move the group
forward, and I am really just one of those individuals.”
Krammes Named FHWA Engineer of the Year
FHWA recently announced the selection of Dr. Raymond
Krammes in the Office of Safety Research and Development
at the Turner-Fairbank Highway Research Center in
McLean, VA, as the FHWA Engineer of the Year.
Krammes completed extensive work in highway
safety, especially in planning, research, development,
contract monitoring, and most recently in implementation
of the Interactive Highway Safety Design Model. His efforts have been a key component of FHWA’s
plan to improve highway safety, especially on
two-lane roads.
Accompanying the recognition as FHWA Engineer of
the Year, Krammes’ application now will be sent to the
National Society of Professional Engineers for consideration
for the Federal Engineer of the Year Award.
Krammes also received the FHWA Administrator’s Award
for Superior Achievement in October 2003.
