The Center for Transportation Analysis (CTA) at NTRC develops integrated intermodal transportation solutions. Research centers around four transportation-related areas: congestion and delay, energy and environment, asset management and logistics, and safety and security. CTA's research and development have significantly influenced the safe, efficient movement of people and goods in our nation's transportation systems.
CTA's research includes visualization and analysis of diverse
data sources. Researchers design support tools that improve data
management and integration techniques for transportation systems.
Research and policy analyses contribute to the development of more
efficient, effective, and equitable policies that allow people and
goods increased mobility while reducing their environmental impacts.
CTA researchers work to improve the operational safety, efficiency,
and security of the nation's transportation systems. They
hold a variety of educational backgrounds, including engineering,
economics, geography, and statistics.
Their success in solving problems centers on their detailed understanding
of the systems they analyze. Researchers conduct statistical analyses,
examine data quality, identify data requirements, collect data,
and integrate data from multiple sources. They develop analytical
and information tools to support federal and state agencies in the
planning, operation, management and maintenance of U.S. transportation
systems. Researchers are also actively involved in professional
communities, including the National Academies' Transportation
Research Board, editorial boards of international refereed journals,
and Congressionally requested policy study committees.
Capabilities encompass a broad array of research areas:
- Aviation safety and air traffic management analysis involves
evaluation of emerging technologies, and systems integration of
those technologies, to improve aviation safety, security, and
air traffic management techniques.
- Energy and environmental policy analysis includes conducting
research and policy analyses that support the development of efficient,
effective, and equitable policies for achieving a sustainable
transportation system.
- Highway safety addresses the highway, vehicle, driver, and environment.
Researchers in this area are active in studying traffic records
and analyzing state and national crash data €les to develop systems
that improve safety.
- Intelligent transportation systems research involves improving
the operational safety, efficiency, and security of our nation's
highways. This research includes evaluation of congestion levels,
accident numbers, delay statistics, throughput, transportation
access, and fuel consumption.
- Modeling and simulation comprises modeling a diverse set of
phenomena from traffic �ows to energy demand, and from travel
behavior to re€nery operations. Researchers have produced critical
planning systems, as well as key components of modeling systems
that are used to enhance transportation systems and the economy.
- Operations research includes modeling traffic networks, shipping
campaigns, and supply chain operations; analyzing and interpreting
associated results; and predicting future traffic networks and
situations.
- Planning and systems analysis develops and applies spatial decision
support systems to traffic forecasting and associated infrastructure
investments.
- Security activities focus on integrated, system-wide security
solutions for all transportation modes that ensure the safe and
secure movement of people and goods throughout the nation.
CTA at the NTRC is part of the Oak Ridge National Laboratory. CTA
works with the Department of Transportation, Department of Defense,
Department of Homeland Security, Department of Energy, and state
agencies to improve our nation's transportation systems.
