ET2000 – In 1991, the TTI-patented ET2000 guardrail end treatment was developed. Over 250,000 units have been shipped throughout the United States and around the world. TxDOT and TTI received the Federal Highway Administration's (FHWA) 1991 Administrator's Biennial Safety Award for their development of the ET2000. Ground Penetrating Radar (GPR) – GPR is a nondestructive geophysical method that "sees" underground and produces a record of subsurface features—without drilling, probing, digging, or coring. Since 1988, researchers at TTI have been developing, testing, and implementing GPR technology for TxDOT to use in its road repair and maintenance activities. Roadway Congestion Index (RCI) – To evaluate mobility levels on Texas streets and freeways, TTI developed the RCI, which is now computed annually for over 85 major U.S. cities. Intelligent Transportation Systems (ITS) – TTI's ITS research has been implemented in several major Texas cities. Real-time train detection and analysis systems have expedited emergency vehicle dispatch, enhanced signal operations, and averted major accidents. HOV Lanes and Managed Lanes – Since the 1980s, many major metropolitan areas have developed HOV or High Occupancy Vehicle lanes to help with traffic flow and provide incentives for carpooling and public transit. TTI has become known as the nation's leader in HOV lane research. Some cities have taken the HOV lane concept one step further in the development of what's being called Managed Lanes. Teens in the Driver Seat – TTI has developed a peer-to-peer driving safety program. Teens in the Driver Seat relies on young drivers themselves to create safety messages and then serve as the messengers to make their peers aware of the risks of teen driving.See also
