Anti-Icing Overlay Helps Prepare Highways For Winter Precipitation
Researchers at the Keweenaw Research Center, a research institute at Michigan Technological University, are developing technology to reduce the treacherous effects of ice formation on highways and bridges.
Russ Alger, director of the Institute for Snow Research at the center, has invented an anti-icing epoxy pavement overlay to prevent vehicles from sliding on ice. The overlay is a sheet of epoxy covered with an aggregate to create a sponge-like surface that soaks in a certain amount of ice-melting chemicals that crews deposit on roadways. By holding the chemicals in place on the roadway--protecting them from premature removal by snowplows or other disturbances--the product is said to help prevent ice buildup.
Use of the overlay on several notoriously treacherous roadways in Wisconsin proved successful in preventing crashes, according to test results from the Wisconsin Department of Transportation.
Alger and others involved with producing the overlay are refining the marketing of the product with a pricing goal that is comparable to other overlays but with the additional anti-icing capability. Alger says the epoxy overlay also can protect pavements from corrosion.

Next Generation Simulation Program
A team of traffic simulation and modeling experts managed by Cambridge Systematics, Inc., and supported by senior advisors from major research institutions and consultants are serving as key contributors to FHWA's Next Generation Simulation (NGSIM) program. NGSIM is a multiyear project for improving the quality, trustworthiness, and usability of simulation tools for better decisionmaking. Other goals are fostering an environment of public-private cooperation and influencing and stimulating the commercial modeling market.
Traffic simulation models offer significant potential for evaluating existing operating conditions on freeways and other transportation facilities. They also can help decisionmakers analyze alternative operational and management strategies. The objective of NGSIM is to develop behavioral algorithms in support of microscopic traffic simulation, with supporting documentation and validation datasets that describe the movement and interaction of multimodal travelers and vehicles on the roadway system and their interactions with traffic control devices, delineation, congestion, and other features of the environment that continually change. All NGSIM products will be available to simulation model developers and the transportation community at large. Current study products are posted on the NGSIM Web site.
In addition to the research consortium of FHWA, private consulting firms, and universities, three stakeholder groups (traffic modelers, software developers, and model users) oversee the work and review the results.

FHWA Wins "Historic Preservation" Award
The Advisory Council on Historic Preservation (ACHP) recently presented its highest award to FHWA for its efforts to protect historic transportation facilities around the country.
Since 1992, FHWA's transportation enhancement program has supported more than 2,500 historic preservation and rehabilitation projects, such as restoration of lighthouses, train depots, and ferry terminals, many of them converted to economic uses for local communities. FHWA is the largest single source of Federal funding available to States for historic preservation.
"We are committed to preserving our historic treasures and supporting the heritage of our communities," says FHWA Acting Administrator J. Richard Capka.
Surface transportation legislation signed in August 2005 by President George W. Bush provides additional resources for transportation enhancement and historic preservation projects.
"This is truly a program where Federal undertakings directly benefit local, regional, and State historic preservation efforts while improving the national infrastructure," says John L. Nau III, ACHP chairman, referring to FHWA's transportation enhancement program.

Work Zone Training for Law Enforcement Officers
FHWA's Office of Safety coordinated the development of a stakeholder-produced, model training course for law enforcement officers who are assigned work zone duties.
Following the investigation of a fatal work zone crash that resulted in the death of a Tennessee Highway Patrol trooper on July 26, 2000, the National Transportation Safety Board (NTSB) recommended developing a model training program for law enforcement personnel to address traffic control strategies used at highway work zones. With the goal of improving communications among law enforcement officials, contractors, and the engineering community engaged in work zone duties, the partners include FHWA, the National Highway Traffic Safety Administration, the International Association of Chiefs of Police, the National Sheriffs' Association, and the American Association of State Highway and Transportation Officials.
The FHWA Office of Safety assumed the leadership role for producing the materials for the course, which will be distributed broadly throughout law enforcement agencies and organizations across the country.
FHWA Launches "ITS Lessons Learned Knowledge Resource" Web Site
USDOT's Intelligent Transportation Systems (ITS) Joint Program Office recently developed a Web site containing lessons learned on planning, designing, deploying, operating, maintaining, and evaluating ITS technologies. Available at www.itslessons.its.dot.gov/its/benecost.nsf/LessonHome, the "ITS Lessons Learned Knowledge Resource" Web site enables members of the ITS community to access the latest knowledge and contribute their own lessons learned.
Each lesson description includes a title in the form of a recommendation, a narrative to provide the context and explain the lesson learned, and identifying information such as the date, location, source, and a contact for more information.
Lesson categories include management and operations, policy and planning, design and deployment, leadership and partnerships, funding, technical integration, procurement, legal issues, and human resources. Within the lesson categories, site visitors also can select application areas, goals, and geographic locations. Previous lessons have discussed the challenges in planning and deploying smart card technology in rural environments, how to develop a formal ITS data-sharing policy for agencies, and the use of task order contracts to develop, deploy, and maintain traffic signal control systems.

IDOT and University of Illinois Create New Transportation Center
The Illinois Department of Transportation (IDOT) recently announced the creation a state-of-the-art research program at the University of Illinois that will conduct studies aimed at producing safer, less congested highways; more environmentally friendly transportation solutions; and longer lasting roads. The State is providing $6.6 million over the first 3 years to build the Illinois Center for Transportation (ICT).
The ICT will be headquartered at the Advanced Transportation Research and Engineering Laboratory (ATREL), part of the University's Department of Civil and Environmental Engineering. Under the cooperative agreement, the center will be administered by the university and will provide state-of-the-art facilities for research and training transportation professionals in both the private and public sectors, as well as providing research opportunities for students.
The ICT will focus on outreach, education, and research to solve transportation problems, reduce congestion, and improve safety and efficiency. The research activities will play a major role in maintaining and operating a premier transportation system to help economic development.
A unique feature is that although administered by the University of Illinois, a portion of the ICT funding will be outsourced to develop cooperative relationships with other Illinois universities and to expose more students to transportation research.
The total funding for the first 3 years is $8.8 million, with IDOT providing a majority of its $6.6 million share through Federal highway dollars specifically earmarked for research purposes. The University of Illinois is providing the local match of $2.2 million to get the program underway.
