NTRC researchers are addressing the nation's major transportation issues. Their expertise could be useful to local transportation companies.

NTRC: Accelerating the Transportation Revolution

Bold New Venture | Origins of NTRC | Hitting Transportation Issues Head-On

East Tennessee is now a magnet for transportation researchers and businesses that should help propel the transportation revolution. The National Transportation Research Center (NTRC) recently opened its doors in northwest Knox County. NTRC brings together under one roof some 160 researchers—120 from Oak Ridge National Laboratory and 40 from the University of Tennessee. With the researchers combining their expertise and the center's state-of-the-art equipment, the NTRC should help solve complex national problems, make the U.S. transportation industry more competitive, and attract transportation-related firms and transportation research talent to the region.

On April 8, 1999, U.S. Transportation Secretary Rodney Slater and U.S. Rep. John J. Duncan, Jr., presided over the official groundbreaking of the $15 million NTRC facility at the intersection of Pellissippi Parkway and Hardin Valley Road. "The National Transportation Research Center is a transportation solution that will improve safety and service for the American people in the new century and the new millennium," said Secretary Slater. "Just as we created a blueprint for an interstate highway system that tied our nation together, the NTRC will help us create a 21st century blueprint for a high-tech transportation system that saves lives, money, and time." Calling the NTRC one of his top priorities, Duncan said that the project" will greatly enhance the ability of the U.S. transportation industry to access the research and technological capabilities" of Oak Ridge National Laboratory.

The NTRC, a collaborative effort among the Department of Energy, ORNL, the University of Tennessee (UT), and The Development Corporation of Knox County (TDC), was built in less than two years on a six-acre site in the Pellissippi Corporate Center. TDC initiated the idea for building NTRC, Inc., and provided the site at a reduced price to the developer. Construction funds for the 83,000-square-foot facility came from Pellissippi Investors LLC, which will lease the facility to ORNL and UT separately. Major support for the facility comes from DOE's Office of Energy Efficiency and Renewable Energy. The Community Reuse Organization of East Tennessee (CROET) provided capital equipment grants totaling nearly $3 million.

Bold New Venture

"Our emphasis will be on getting technology out to the private sector as quickly as possible," says Bob Honea, an ORNL manager named NTRC director. "The center represents a bold new venture that departs from the traditional ways in which government, industry, and the public sector have operated. For example, our transportation researchers from ORNL will no longer be behind a guarded fence, so they will be more accessible to private companies needing help with their transportation problems.

"Each collaborator brings important capabilities and assets to the facility, which we expect to attract the best talent available in transportation fields. The center and NTRC, Inc., will build upon and expand DOE's existing partnership with other federal agencies, such as the Department of Transportation and the Department of Defense."

David Greene, one of the ORNL researchers who has moved to the NTRC, believes that the existence of the center and NTRC, Inc., will open up new lines of research and sources of funding beyond what DOE offers. "We may have easier access to funding from the automakers, the oil companies, the National Science Foundation, and the Pew Charitable Trust," he says.

Researchers from industry, government, universities, and other laboratories around the country can call upon NTRC, Inc., for expertise in many different fields of transportation. NTRC researchers are determining the energy efficiency of vehicles and engines and the effectiveness of their emissions-control systems. Some are looking at ways to improve road-paving materials. Others offer advice on packaging and transporting hazardous materials and high-value products. Research is being conducted on intelligent transportation systems, defense transportation and logistics, transportation manufacturing research, composite materials for vehicles, and geographic information systems used to identify alternative transportation routes around congestion. Computer simulations of car crashes and other research methods will be used to find ways to improve vehicle safety and to evaluate the performance of new lighter-weight materials. The NTRC will also house researchers doing planning and policy analysis concerning vehicle fuel efficiency and energy use in the transportation sector.

The UT Center for Transportation Research will be conducting research at NTRC on how to make car interiors safer and how to prevent injury to body extremities in car crashes. UT researchers will also be investigating better paving materials and improved bridge beam construction. (See UT Goal: Safer Trips.) UT brings to the NTRC several nationally recognized R&D programs in transportation logistics and advanced vehicle technologies, with a base funding approaching $20 million. The Geographic Information Systems (GIS) laboratory at the NTRC, which is staffed mostly by UT researchers, is developing a map-based application that allows Tennessee Department of Transportation planners to identify roadway deficiencies and model recommended improvements to determine the costs and benefits of construction projects. The GIS group is also involved in a number of military logistics projects, such as identifying potential bridge and interchange deficiencies along convoy routes and prescribing alternate routes if necessary. (See Transportation Planners Aided by GIS Research, Defense Transportation and Logistics Research.) Specialized transportation research laboratories at NTRC and ORNL that have the best modern equipment will be available to users. DOE brings to the NTRC the scientific and technical capabilities of ORNL plus its existing funding base of nearly $80 million in transportation research and development (R&D) from multiple sponsors.

Origins of NTRC

How did the NTRC begin? "It all began on September 10, 1993," Honea says. "A group of movers and shakers doing transportation research at ORNL decided at an off-site meeting at the Tellico Village Yacht Club that it would really be great to get together in one building. At that time we were scattered all over the Oak Ridge Complex and rarely saw each other except at off-site meetings. But when we got together, things really clicked and we found we all had a lot in common. So I was asked to begin looking for a building to house the group. Initially, we thought about asking UT if the university would be willing to build a facility to sublease to us, but UT's administrative management couldn't do that.

"We had almost given up when TDC expressed interest in helping us build the facility. Then TDC officials decided that their charter only allowed them to provide land, not construct buildings. Later, we evolved the idea of including in the building some transportation research labs as user facilities for outside researchers. In that way we were able to get DOE support. We talked to several private investors and looked at many sites before we settled on the Pellissippi Parkway site. Mr. Stan Roy, Mr. Milus Skidmore, and the Malicote family, who own Dixie Roofing, Inc. (whose president is Mike Malicote), formed a partnership called Pellissippi Investors to bid on the project using private funds to construct the building. We are now beginning to enjoy a fantastic facility."

Hitting Transportation Issues Head-On

The U.S. transportation system, which has long been a key to the success of our American economy, is a source of problems that could be partially solved by technology. Integrated technologies and appropriate policies could revolutionize the American transportation system so that its value to the economy is no longer undermined by its external costs. NTRC researchers are working on technological solutions to these transportation issues. Following is a look at some of these transportation issues and the solutions proposed by NTRC researchers.

• The American transportation system is responsible for one-third of the energy we use and one-third of our carbon dioxide emissions, which could contribute to unwanted climate changes.

One approach to solving these problems is to educate the public about the importance of buying cars and trucks that use fuel more efficiently so that less carbon dioxide is emitted. David Greene of ORNL's Energy Division is helping this effort through www.fueleconomy.gov, a Web site he manages and writes for DOE. The Web site, which was designed by UT's Janet Hopson, has been named "site of the day" by Yahoo (an Internet company) and USA TODAY. It gets 1000 visitors a day.

According to Clean Energy for the 21st Century, a document by DOE's Office of Energy Efficiency and Renewable Energy (EERE), which funds much of the research at NTRC, "DOE and six other federal agencies are working with the major U.S.-based auto makers in the Partnership for a New Generation of Vehicles (PNGV), which has the goal of creating by 2004 a full-size car that achieves 80 miles per gallon, without sacrificing safety, affordability, or other features we expect in an American car."

Using PNGV funds, ORNL researchers are studying better and cheaper ways to manufacture lightweight carbon-fiber composites to replace steel for body parts and other components of advanced vehicles; the lighter the vehicle, the less fuel it will require. They are also developing smaller electric motors and power electronics modules for hybrid vehicles, to make them more efficient. Hybrid vehicles use less gasoline or diesel fuel because they have an electric motor to help power the wheels during acceleration and stopping. (Some of the composites and electric motor researchers have their roots in the Oak Ridge gas centrifuge program of the early 1980s, which sought to develop a more efficient way to produce enriched uranium for nuclear power plants.) NTRC researchers will also be measuring the speed, power, and overall energy efficiency of engines and vehicles (especially foreign cars incorporating new technologies, to compare them with new American models). For this research, they will use engine dynamometers and a chassis dynamometer, which is like a treadmill for a car. One goal of this research is to help the U.S. automobile industry become more competitive in the world marketplace.

• Because of our growing transportation needs, half of the oil our nation uses is imported, jeopardizing our national security and economic health. According to www.fueleconomy.gov, "The vast majority of the world's oil reserves are concentrated in the Middle East (65% to 75%), and controlled by the members of the Organization of Petroleum Exporting Countries (OPEC) oil cartel. Transportation accounts for two-thirds of total U.S. petroleum use and nearly all of the high-value petroleum products, like gasoline and distillate fuel. In the past, dependence on oil has cost our economy dearly. Oil price shocks and price manipulation by the OPEC cartel from 1979 to 1991 cost the U.S. economy about $4 trillion, almost as much as we spent on national defense over the same time period and more than the interest payments on the national debt. Each major price shock of the past three decades was followed by an economic recession in the United States. With growing U.S. imports and increasing world dependence on OPEC oil, future price shocks are possible and would be costly to the U.S. economy."

One possible solution to this problem is to encourage more people to buy and drive hybrid vehicles. ORNL and UT are working on this challenge. NTRC researchers are developing the smaller electric motors and power electronics modules required for hybrid cars and fuel-cell electric cars.

• Oil supplies are being gobbled up so fast that future generations may not have much fuel left for transportation. According to www.fueleconomy.gov, "It took more than 200 million years to form all of the oil beneath the surface of the earth. It has taken 200 years to consume half that endowment. If current rates of consumption were to continue, the world's remaining resources of conventional oil would be used up in 40 years."

One approach to sustaining future generations is to use alternative fuels from renewable sources, such as ethanol, to power cars and trucks. ORNL researchers are developing ways to produce more ethanol from corn and waste wood, using better enzymes and microorganisms. Other ORNL scientists are looking at ways to genetically alter hybrid poplar trees and switchgrass so that they hold more carbon as they grow, making them even better sources of ethanol.

As part of EERE's effort to expand the use of alternative fuel vehicles, which use ethanol, natural gas, methanol, or electricity, ORNL has a fleet of "green cars" that operate on E-85 fuel, which is 85% ethanol. EERE is also seeking to stimulate the development of a refueling station infrastructure throughout the nation.

• Partly because of transportation, air quality is declining in our metropolitan areas and national parks, aggravating the health of people with respiratory illnesses. ORNL researchers at the Advanced Propulsion Technology Center, a user facility that is being relocated to the NTRC, are studying the effects of high-sulfur and low-sulfur gasoline and diesel fuel on the emissions of vehicles with advanced emission control systems. Too much sulfur can poison advanced catalysts, making them gradually ineffective at removing nitrogen oxides, hydrocarbons, and particulates. Federal regulations call for reduced automotive emissions of these pollutants and the gradual use of ultra-low-sulfur fuels in vehicles.

• Increased traffic congestion and deteriorating roads, as well as congestion on our rivers and at our airports, are causing losses in productivity and profits. ORNL researchers have been developing computer models of traffic congestion on freeways, growing congestion of barge traffic on a major river, and airplane congestion en route to airports. These models are providing insights into how to reduce congestion. Software tools are being developed at NTRC to help emergency responders avoid streets that are closed or blocked. NTRC researchers are also developing weigh-in-motion methods to speed up the accurate weighing of trucks, to reduce highway congestion around weigh stations.

Traffic congestion
Traffic congestion causes losses in productivity and profits.

• More than 41,000 people die each year on U.S. highways. NTRC's development of tools to weigh trucks faster and comprehensively test their brakes and rollover stability could ultimately increase highway safety if the technology catches on. NTRC is also boosting highway safety through its evaluations that ensure that hazardous materials are properly packaged and transported along routes in less populated areas. In this way, packages are less likely to release their contents in case of an accident in transit and thus possibly expose a large population.

ORNL researchers are developing computer tools to help traffic management centers anticipate and avoid unnecessary congestion, which can lead to traffic accidents and waste fuel. They are also trying to determine whether car cell phones, PCs for e-mail and Web surfing, and navigational systems that guide drivers around heavy traffic and help them avoid accidents cause "information overload" that might undermine the technologies' contributions to safety. ORNL researchers are also using supercomputers to simulate collisions involving vehicles designed to use materials lighter than conventional steel, such as high-strength steel, aluminum, and carbon-fiber composites. The purpose is to determine whether new, lighter cars will hold up in accidents as well as or better than today's heavier steel cars.

Patricia Hu, director of ORNL's Center for Transportation Analysis (CTA), is studying older driver safety. In research conducted for General Motors, Hu and her colleagues at CTA project that highway fatalities of drivers over 65 years old will almost triple by the year 2025, compared with the number for the same age group in 1995. This increase is due to the expected increase in the number of older people in the general population and, subsequently, on the highway, coupled with the increase in traffic. CTA's research shows that some older women often stop driving prematurely (for example, after their first stroke) whereas some older men tend to drive until they have had a second stroke. Older men who have impaired vision and limited motor skills and use anti-depressants are at a greater risk of being involved in highway crashes than other older male drivers.

However, Hu says that the expected increase in highway crashes will be partially offset by a decrease in the crash risk as a result of currently evolving technologies (e.g., airbags and intelligent transportation systems). The CTA study suggests that new technologies could reduce the crash risk even more.

Thanks to new technology development and policy analysis occurring with support from NTRC, Inc., ORNL, and UT, beneficial results of the transportation revolution may be just down the road.
