3. Six years after TTI was formed, U.S.
President Dwight D. Eisenhower signed the
interstate highway bill in 1956, establishing
not only a transportation systems approach
and a design concept for our nation’s
major roadways, but also a financing
mechanism. The country established an
interstate highway plan, a federal gas tax
and a highway trust fund, all of which truly
changed the nation and helped make the
United States an economic superpower and
the envy of the world.
vision
A successful 21st century transportation system must be different from the past. At TTI, we are
focusing our attention on research development and entrepreneurship. We are working to leverage
the present transportation infrastructure more effectively and operate existing transportation facilities
in the optimal manner. We are seeking to manage the demand on the system by studying usage
patterns and identifying choices, such as additional transit availability and bicycling and pedestrian
options, as well as behavioral changes, such as telecommuting, flexible work options, and other trip
reduction strategies.
Freight transportation and intermodal connections are high priorities, and TTI is coordinating efforts
among transportation modes. Our experts are focusing on how to connect our roadway infrastructure
to fast-developing automated and connected vehicle technologies, and the policy implications of
these new technologies. The results of our efforts will be a comprehensive, systematic approach to
providing a productive, scalable 21st century transportation system for generations to come.
Our Vision
transportation
century
system
the21st
Today transportation connects every aspect of our lives:
home, work, education, commerce and recreation. Over the
past 65 years, the U.S. population has more than doubled.
The number of cars and trucks on the road reached almost
253 million. Now, the nation’s roadway capacity is growing
only modestly compared to the rate of expansion that resulted
from the interstate highway bill. At the same time, there are
more cars on the road than ever before competing for the
available roadway supply. TTI’s annual Urban Mobility Report
illustrates the national interest and concern about mobility
and congestion, the time lost, and the costs encountered.
The need for transportation research has never been greater.
Transportation and TTI

4. The legacy of TTI is about
a team of researchers in pursuit
of a better way to develop and
maintain a safe and efficient
transportation system — saving
lives, time and resources.
The original 1950 charter of TTI,
established by the Agricultural
and Mechanical College of Texas
Board of Directors, charged
the Institute with enlisting the
broad resources of the college
in all forms of transportation
research, while giving students
the opportunity to study and work
in the transportation profession.
This agreement solidified the
Cooperative Research Program
between the then Texas Highway
Department — now the Texas
Department of Transportation
(TxDOT) — and TTI. It formed the
basis for TTI’s development and
success through the years.

5. Mobility
Mobility analysts at TTI examine problems
associated with congestion and access to
transportation, develop innovative solutions,
and measure the effectiveness of the out-
comes. TTI prepares the definitive national
study documenting congestion costs and
trends in almost 500 U.S. urban areas. The
Institute also provides expertise in metro-
politan, urban, and rural bus and passen-
ger-rail transit planning and operations.
Safety
The Institute’s safety innovations can
be found throughout Texas and around
the world. Major advancements have
occurred in the design of roadside
safety devices such as guardrails, crash
cushions and sign supports. TTI is leading
other significant advancements in traffic
signals and signs, distracted driving and
crash analysis, and bicycle and pedestrian
safety, just to name a few.
Human and Behavioral Studies
Roadway users play a critical role in the
safety of our nation’s roadways. TTI’s
Human Factors Program examines human
limitations and capabilities, and works
to optimize the user-vehicle and user-
roadway interfaces to improve safety. The
Behavioral Research Program examines
roadway user attitudes and actions to
help identify methods to promote safer
behavior.
Environment
As the U.S. Environmental Protection
Agency’s standards evolve, the sophistica-
tion of the environmental research meth-
ods necessary to test for these standards
also changes. TTI is focusing on transporta-
tion-related air quality, sustainability, ener-
gy and climate change, and sediment and
erosion control through its environmental
research programs and facilities.

TTI researchers are developing and testing
innovative applications for advancing
connected transportation. Along with the
Accelerate Texas Center, TTI’s connect-
ed transportation initiative includes an
automated and connected transportation
system testing facility in development
at TTI’s Proving Ground and a variety of
urban test beds.
Focus Areas
Infrastructure
TTI is finding innovative and cost-effec-
tive ways to maintain and rehabilitate
roadway infrastructure. Researchers
have assessed land-side improvements
that may be needed to effectively serve
additional port, rail and truck traffic
generated by the expansion of
the Panama Canal.
Freight Movement
TTI is exploring innovative solutions that
support the use of multiple modes of
transportation, facilitate freight transfer
and operation, enhance freight mobility,
improve air quality, and reduce border wait
times. TTI has also developed an innova-
tive technology called the Freight Shuttle
System, which has the potential to revo-
lutionize freight movement by improving
safety, reducing emissions and decreasing
shipping costs.
Security
The Institute has successfully developed
and evaluated new technologies resulting
in the cost-effective implementation of
devices and standards to help keep our
country safe from terrorists. In the area of
homeland security, TTI conducts testing
of antiterrorist safety barriers for the U.S.
Department of State, Bureau of Diplomatic
Security, U.S. Army Corps of Engineers
and private-sector companies.
Workforce Development
TTI employs more than 200 students in
its research laboratories and offices. Over
40 Texas A&M University faculty regularly
work on TTI research projects. TTI experts
also provide training on transportation
topics. Many of TTI’s researchers are rec-
ognized national and international leaders
in their fields, including about 80 who
lead or serve on Transportation Research
Board (TRB) committees.
Policy
TTI provides information critical to state
and national decision makers in the areas
of transportation policy. Institute research-
ers are often asked to offer objective and
credible testimony on a wide range of
transportation topics and emerging issues.
With the addition of the Transportation
Policy Research Center in 2013, TTI contin-
ues to serve as a valuable resource to the
Texas Legislature.
Planning and Operations
Researchers at TTI continue to be at the
forefront of using data collected from
Bluetooth®
devices, cell phones, GPS,
web surveys and virtual open houses to
engage the public and other stakeholders.
The information collected includes trip
purposes, origins and destinations;
travel times and speeds; and needed
improvements. This input helps determine
a desirable combination of multimodal
transportation projects.

7. Traveler Information
Innovative research for TxDOT on the
Central Texas I-35 corridor has resulted
in implementation of the most advanced
online, real-time construction traveler infor-
mation map in the nation. A unique end-
of-queue warning system works with radar
detection devices and portable changeable
message signs deployed in work zones to
warn drivers of stopped traffic. These tech-
nologies are helping reduce congestion and
the frequency of rear-end collisions.
Visibility
Enhanced pavement marking research
is testing various camera-based systems
and new sensing technologies to detect
existing and prototype pavement mark-
ings. The research will support automat-
ed vehicle deployment and is identifying
possible limitations, areas for further
research and new applications.
Connected Transportation
The I-35 Connected Work Zone, a project
TTI is undertaking for TxDOT, will focus
on improving freight movement along the
construction corridor by providing trucks
with traveler information through onboard
devices capable of receiving work zone
infrastructure data. The project, funded by
the U.S. Department of Transportation, will
provide lane closure locations, delay lengths
and projected delays up to a week in advance.
Asset Management
TTI conducted an extensive pavement
evaluation of 160 miles of I-20 in the
Odessa TxDOT District using Ground
Penetrating Radar and Falling Weight
Deflectometers. Researchers analyzed
core samples, assembled traffic load data
and compiled maintenance histories. After
a complete data analysis, researchers
developed a 10-year rehabilitation plan
with priorities and proposed short-term
and long-term rehabilitation options, which
have saved several million dollars to date.
Integrated Corridor
Management
TTI has been a key member of a U.S.
Department of Transportation–sponsored
team that is pilot-testing and implementing
an innovative decision support system for
traffic operations agencies and commuters
in the Dallas area. With a 20:1 return on
investment over 10 years, the project is
making real-time incident, delay and alter-
native route information easily available.
Transportation and Public
Health
Data specialists are consolidating and ana-
lyzing trauma, crash, citation, engineering
and emergency management system data.
This effort will help prevent crashes and
improve injury treatments by increasing
the understanding of how crash, response,
transport and treatment characteristics
affect medical outcomes.
Featured Projects
futureinnovations
Freight Shuttle
The Freight Shuttle System (FSS)
consists of electrically powered, autono-
mous vehicles that travel on an elevated,
derailment-proof guideway between
strategically located terminals. As a
commercially sustainable transport option
for shippers and trucking interests, the
FSS, currently in development in the
private sector, will also provide improved
highway safety, congestion relief and
reduced infrastructure damage.
Sustainability
The TTI-developed Guidebook for
Sustainability Performance Measurement for
Transportation Agencies provides a generally
applicable framework that transportation
agencies can adapt and use, either in their
existing performance measurement pro-
grams or as a part of a new sustainability
initiative. The guidebook offers a practical
approach for identifying and applying
sustainability-related performance
measures.
Big Data
TTI has a rich history in big data devel-
opment and analysis in such areas as
intelligent transportation systems and
integrated corridor management on U.S.
highways and at international borders.
Using geographic information system tools
and color-coded maps, TTI researchers
are visually layering various transporta-
tion data sets, providing a more thorough
assessment of diverse and sometimes
competing transportation needs.
Driver Behavior
A TTI analysis is the first to compare voice-
to-text and manual texting on a handheld
device in an actual driving environment,
finding no differences in the level of driver
distraction between the two activities. The
findings offer new insights but are only a
part of the knowledge needed to improve
roadway safety.
Energy Development
Energy development impacts on the trans-
portation system span multiple areas, such
as pavement life, right of way, roadside and
operational safety, and economics. To tackle
these issues, multiple TTI projects are
developing and implementing technologies
such as GPS and radar-based pavement
diagnostics, 3D right-of-way management
tools, geodatabases, and a roadmap for
sustainable transportation and energy
systems initiatives.
Travel Forecasting
Advanced travel forecasting techniques
developed at TTI are helping decision
makers determine which transportation
investments will be the most effective.
These techniques help predict demand in
highly congested corridors, such as I-35
in Central Texas and U.S. 59 in southwest
Houston, and include simulations of
individual driver responses to proposed
facility designs.

TTI plays a key role in training and educat-
ing the next generation of transportation
professionals. Over 40 TTI researchers hold
joint academic appointments at Texas A&M.
One-third of TTI’s staff are students — about
half are undergraduates and half are graduate
students. The academic faculty facilitate the
educational mission of the Institute and help
attract students into the transportation pro-
fession. TTI faculty relationships also provide
a direct link to scientific expertise, technolo-
gies and equipment that provide a competi-
tive edge for TTI’s research program.
The Institute maintains a close association
with the Texas A&M University Dwight
Look College of Engineering, the College of
Architecture, and the George Bush School
of Government and Public Service, as well as

technical expertise and reputation for objectivity. Many are recog-
nized national and international leaders in their fields. TTI researchers
contribute to the growth of the transportation profession by par-
ticipating in and leading hundreds of local, state and national orga-
nizations. For example, since the inception of the TRB Cooperative
Research Program, TTI has been a leading participant in the National
Cooperative Highway Research Program. The Institute also has led
and participated in cooperative research programs in transit, aviation,
freight and hazardous materials.
With expertise in areas such as engineering, planning, economics,

for erosion and sediment control, vegetation manage-
ment, and stormwater-quality improvement. The lab-
oratory’s bench-scale capabilities include scale slope
testing and channel erosion testing. A 2,800-square-
foot, climate-controlled greenhouse is used for growing
approved seed mixes free from weeds and other outside
contaminants. The indoor rainfall simulator has adjustable
soil beds to provide a practical range of desired slopes
and control over water drop size, distribution and impact
velocity. A mobile rainfall simulator is available to provide
similar test conditions at any remote location.
Environmental and Emissions
Research Facility
One of the largest drive-in environmental chambers
in the United States is used for research and testing
designed to help lower vehicle emissions, improve air
quality, and provide reliable information for state and
national policy makers. This 7,500-square-foot facility can
house tests using a full tractor-trailer rig or municipal bus
at constant temperatures ranging from −25°F to +131°F
and a controllable relative humidity of up to 70 percent.

Bridge Performance Test Bed
A spread slab beam test bridge, developed for a TxDOT research
project, uses fewer beams than traditional slab beam bridge designs,
with the goal of maximizing road-building dollars. The test bridge
is instrumented with multiple load cells, strain gauges and string
potentiometers. Load cells below each beam determine how the load
is distributed when a heavy vehicle crosses the bridge. The resulting
data provide insight into best practices for future bridge design.
Eye-Tracking Equipment
TTI’s eye-tracking systems use small infrared emitters and cameras
to track eye movement and pupil size with respect to what drivers
are seeing in real time at 60 Hz. These systems assess driver look
behavior in the TTI driving simulator or on the open road both in the
daytime and at night. Behaviors examined include primary driving
tasks, such as reading signs or detecting pedestrians, and non-driv-
ing tasks, such as texting while driving.
