FY 2003 Performance Report
The following T&Is have been identified as warranting special attention. Technologies on this list are ones that:
This list is not intended to include all T&Is available. Numerous T&Is are being developed, but are not yet ready to be marketed in the field. In addition, many T&Is are considered good concepts, practices, and/or success stories that should continue to be shared. This initial list is intended to be a living list: A process will be developed for reviewing and updating these T&Is.
*511 Traveler Information—An easy-to-remember three-digit telephone number available to State and local transportation agencies nationwide so that they can readily provide information and highway and transit conditions to travelers by telephone. Travelers can make more informed decisions regarding travel routes and modes, resulting in a more balanced transportation network.
Contact: Bob Rupert, 202–366–2194.
Asset Management Guide—The guide, along with the companion NHI course, illustrates asset-management principles and identifies techniques and methods for adopting the decisionmaking framework in transportation agencies.
Contact: Stephen Gaj, 202–366–1559.
Augered Piles—The technology is characterized by drilling a hollow-stem auger into the ground, forming the diameter of the pile. Sand-cement grout or concrete is pumped into the hole as the auger is being removed from the hole, eliminating the need for temporary casing. After the auger is removed, reinforcement is installed in the pile. For certain applications, these foundation systems can be constructed more quickly and less expensively than can deep foundation alternatives.

Contact: Hari Kalla, 202–366–5915.
*Roundabouts—A circular intersection that requires entering vehicles to yield to existing traffic in the circulatory roadway. Studies show that modern roundabouts can reduce intersection fatalities by up to 90 percent, reduce injury crashes by 76 percent, and reduce pedestrian crashes by 30–40 percent.
Contact: Hari Kalla, 202–366–5915.
*Rumble Strips—Shoulder rumble strips are continuous grooved indentations in roadway shoulders that provide both an audible warning and a physical vibration to alert drivers that they are leaving the roadway. Studies have shown that these strips yield a significant reduction in run-off-the-road crashes.
Contact: Dick Powers, 202–366–1320.
*Safe Speeds in Work Zones—Two technologies that can improve work zone safety for highway users and workers. Two technologies that can improve safety in work zones are portable speed limit signs that automatically display safe speed based on traffic conditions and the nature of the roadwork, and feedback displays that show the speed of approaching vehicles.

Technology Implementation Group Approved Technologies
AASHTO created the TIG to identify high-payoff, ready-to-use technologies and to champion the implementation or deployment of these few select technologies, products, or processes that are likely to yield significant economic or qualitative benefits to the users throughout the country. FHWA works closely with and fully supports the AASHTO TIG initiatives and the implementation of the approved TIG technologies. The FHWA Priority, Market-Ready Technologies and Innovations include the following nine approved AASHTO TIG technologies.
Accelerated Construction—This undertaking promotes creative techniques to reduce construction time and enhance quality and safety. This includes techniques and elements along with innovative contracting practices that reduce congestion and enhance quality and safety.
Contact: Dan Sanayi, FHWA, Dan.Sanayi@fhwa.dot.gov.
Air Void Analyzer—The Air Void Analyzer can be used to provide real-time evaluation for measuring air content, specific surface, and spacing factor of fresh PCC. This real-time evaluation can improve quality control. Implementation goals include developing a common standard test protocol, specifications, and a data-collection form.
Contact: John Wiakowski, Kansas DOT, JohnW@ksdot.org.
Fiber-Reinforced Polymer (FRP)—This material can be used to repair cracks in overhead sign supports when the support is wrapped with the fiber-reinforced material. FRP can prevent overhead sign support failure and provide structural integrity to the overhead sign support.
Contact: Paul Wells, New York State DOT, email@example.com.
Global Positioning System (GPS) Surveying—The GPS uses satellites that transmit signals continuously; it has many highway applications, including surveying pavement conditions and inventorying highway assets. GPS increases accuracy and reduces labor, time, and costs.
Contact: Charlie Brown, North Carolina DOT, CharlieBrown@dot.state.nc.us.
Ground-Penetrating Radar—Vehicle-mounted ground-penetrating radar can be used to collect information about underlying highway pavement layers without incurring the time and labor costs and traffic delays associated with traditional methods of drilling for core samples. This vehicle-mounted technology collects pavement layer thickness and identifies rapidly deteriorating pavement areas at normal highway speeds.
Contact: Mike Murphy, Texas DOT, firstname.lastname@example.org.
Highway Rail Warning System—A low-cost active warning system used at low-volume, highway-railroad at-grade intersections. The system consists of locomotive-installed hardware that communicates with the crossing device to activate the signals; it can upload and download data on nearby crossings and report on system operations or health. Most often mounted on standard crossing poles, this technology is solar/battery-powered with wireless communications between the device and the locomotive.

*ITS Technologies in Work Zones—The use of ITS technologies in work zones, such as ramp-metering systems, intrusion alarms, and queue-detection information (sensors/cameras), is aimed at increasing safety for workers and road users and ensuring a more efficient traffic flow. These technologies provide ways to better monitor and manage traffic flow through and around work zones, and thus minimize the impact of delays and increase safety.

Prefabricated Bridge Elements and Systems—These prefabricated elements and systems may be manufactured on- or offsite, under controlled conditions, and brought to the job location ready to install. These systems minimize traffic impacts of bridge construction projects, improve construction zone safety, make construction less disruptive for the environment, increase quality, and lower life-cycle costs. Using these systems reduces traffic and environmental impacts by minimizing the need for lane closures, detours, and use of narrow lanes.
Contact: Mary Lou Ralls, Texas DOT, firstname.lastname@example.org.
Thermal Imaging Safety Screening System—The system allows an operator at a weigh station to view the relative temperatures of brake drums through the wheel rims of commercial vehicles. The infrared image of a correctly operating brake system shows all brake drums to be hot and approximately the same temperature when the vehicle is braking. When a brake is defective, the brake drum appears to be the same temperature as the wheel rim and darker than a properly operating brake. The system was developed using commercial, off-the-shelf components and advanced infrared image acquisition, processing, and storage.
