The Transportation Research Center (TRC) is North America's largest multi-user automotive proving ground. It is operated by TRC Inc. The center occupies 4,500 acres in East Liberty, Ohio, about 40 miles northwest of Columbus, Ohio. These 4,500 acres are split between the main TRC property and a rural road/ATV course located approximately 2.5 miles from the main property.
The National Highway Traffic Safety Administration (NHTSA) has its Vehicle Research and Test Center (VRTC) on TRC property. TRC is the only North American proving ground with a government research and test center on site.

## History

In 1962, the College of Engineering at The Ohio State University (OSU) established a center to coordinate and encourage transportation-related academic and research programs. The university envisioned a facility for controlled transportation research without using public roadways, with their control and safety problems. The concept was funded by a portion of the proceeds of a State of Ohio highway bond issue approved by the voters in 1968. TRC was funded to enhance the health, safety, and personal welfare of all inhabitants of the State of Ohio.
In 1968, the State of Ohio purchased 8,100 acres of land and construction began. Since opening in 1974, TRC has operated on its own revenues. In 1972, the Ohio Legislature created TRC of Ohio and established the Transportation Research Board for the control, management, supervision, and direction of the Center. Subsequently, the Board hired a staff to operate the facilities.
In June 1979, the Board contracted with OSU to manage the operations and staff of the TRC of Ohio. In September 1987, TRC's property was offered as part of an economic inducement to attract Honda to build an automobile plant in Ohio. On January 26, 1988, the property sale was consummated and TRC Inc. was formed as successor to the Transportation Research Board. TRC Inc., a non-profit Ohio corporation, affiliated with OSU, entered into a management agreement with Honda to continue to operate the TRC as a multi-user, independent test site. The present TRC Inc. is owned by OSU and is the facility manager for the Honda owned property (TRC).

ISO Noise Pad: A 65-ft. by 123-ft. pad allows manufacturers an opportunity to evaluate their products to ISO noise requirements.
Skid Pad: Used for brake and low speed durability testing. This 84-ft. by 9,000-ft. facility contains five smooth lanes for braking flanked by two lanes utilized for rough road durability testing. The durability courses contain rough road surfaces such as resonance, impact and chatter bumps, chuckholes, V-ditches, twists and washboards. This facility also contains 6 crosswind generators capable of a 40-mph output.
Dynamic Handling Course: 1.75 mile asphalt course consisting of a variety of slow, medium, and high-speed corners, slight elevation changes, and turns of varying camber. Winding Road Course: 1.5-mile winding road course with wet and dry pavement capabilities. This course also contains two depth-controlled hydroplane test areas as well as a 203-foot radius wet vehicle dynamics handling area.
Bus & Truck Durability Course: The 2,000-foot by 24-foot wide course consists of: staggered bumps, sine wave course, chuckholes, chatter bumps and a high crown intersection.

### Emissions Laboratory

Supports chassis based exhaust emissions testing of motorcycles, ATVs, UTVs, passenger vehicles and light duty trucks. Small to medium size motorcycle and ATV testing is performed on a Horiba chassis dynamometer with a single axle 20 inch diameter smooth roll. Large motorcycle, UTV, passenger vehicle and light duty truck testing is performed on an AVL 2 axle All Wheel Drive (AWD) chassis dynamometer with 48 inch diameter smooth rolls. The AWD dynamometer can be operated in front wheel drive, rear wheel drive or AWD modes. Both chassis dynamometers are AC motoring and meet EPA requirements for chassis based exhaust emission and Deterioration Factor Service accumulation testing. Exhaust emissions are measured using a 2013 model year AVL iGem i60 CVS dilute emissions bench. The bench is capable of measuring tailpipe exhaust emissions produced by gasoline and diesel engines. The AWD dynamometer Test Cell temperature can be set for vehicle testing between 20F (-6C) and 100F (38C).
