No. 5, March/April 2003

A Natural Choice by Lloyd Middleton and Mitch King Using compost for environmentally sound roadside slopes is one time when waste pays off. EFLHD investigated the use of compost as an alternate technique to hydroseeding and silt fences for revegetating a steep rockslide on a section of the National Park Service's Blue Ridge Parkway. The article describes the steps taken in the compost installation, the results, and the economics of compost as an alternate method. The authors conclude by suggesting that FHWA adopt compost as a best management practice for some situations.	2
Behind the Scenes at the Olympics by Pamela Mathis The Utah DOT shares the know-how that it gained from managing transportation for such a major event. This post-Olympics article—a follow-up to the pre-Olympics piece that was published in the Jan/Feb 2002 issue of Public Roads—is substantially different from the earlier article in that it shares the lessons learned from managing transportation for such a major event. The advice that the Utah DOT provides could be useful to any transportation agency for events such as football games, concerts, and major holiday events. FHWA's Paul Mooney advised us to focus solely on the Utah DOT's efforts, for political reasons, so we just mentioned FHWA in passing along with UTA, SLOC, Salt Lake City, and others. The information provided by Utah DOT focuses on interagency cooperation through a jointly staffed TOC, a public relations information campaign, various operational tools such as increasing the size of the IMT crews and instituting a traffic observers program, making use of CCTVs and VMSs, and extensive training simulations.	6
Technology Goes Local by John J. Sullivan IV A showcase program in Florida spurs local implementation of proven highway technologies. The Florida LTAP center initiated a demonstration program that aims to improve technology transfer and implementation at the local level. The article explores Florida's innovative showcase program and offers several examples of technologies highlighted during these events (equipment for collecting data on pavement resurfacing, open-graded emulsified mix for paving unpaved roads, in-road warning system for occupied pedestrian crosswalks, roundabout for reducing traffic congestion, and construction of a multiuse pedestrian and bike trail through multiagency jurisdictions). The article also discusses guidelines for and evaluation of a showcase, and suggests that other States consider using a similar approach to spurring technology adoption by municipalities and counties.	10
A Conduit for New Technology by Kathleen A. Bergeron Videoconferencing can be a cheaper, faster, safer way to spread the news about the latest transportation innovations. Videoconferencing offers a potentially cheaper way to transfer transportation technologies, versus meetings involving physical travel to demonstrate technological innovations. By eliminating travel, videoconferencing means that technology transfer also can occur more quickly and safely. State DOT engineers, for example, may work under a quota policy that permits only one out-of-state business trip per year. The article describes the history of these "virtual meetings" and their use by universities, Federal agencies (including a sidebar on FHWA's use), the highway industry's use for training, use by State DOTs and WASHTO-X (a research study of telecommunications by the Western Association of State Highway and Transportation Officials). The article concludes by examining the historical reasons why "picture phones" were slow to catch on and mentions how WASHTO-X is examining why users potentially may be slow to adapt to the changes required by teleconferencing, how people can become comfortable with the equipment, and the differences in meeting style and etiquette. The author had decided to include a brief sidebar comparing the costs of a sample meeting with the costs of videoconferencing, but has not yet provided the sidebar.	15
The Man Who Changed America, Part I by Richard F. Weingroff President Eisenhower's interest in good roads began in 1919 and resulted in the Federal-Aid Highway Act of 1956—but he had to fight for his Grand Plan. This lengthy historical article by Richard Weingroff of FHWA is similar to other Weingroff articles that we've published in the past in that the article details the political and legislative process during the Eisenhower years of the 1950s when Ike brought the Interstate System into existence. The article begins with 8 pages of background information setting the stage and then begins the legislative process with Truman's Federal-Aid Highway Act of 1952. Then the author provides a blow-by-blow account of the battle with the Governors over the controversial issue of State versus Federal funding of the Interstate System. The story continues in Part II of the article, which will be published in the following issue of Public Roads.	20
Living Up to a Landmark by Norah Davis Building a bridge that will overlook Hoover Dam—and enhance it—is a once-in-a-lifetime engineering challenge. The article begins and ends with the aesthetic challenges of constructing a bypass and bridge in close proximity to Hoover Dam that will be worthy of this national historic landmark. Addressing the aesthetic challenge, selecting a route for the bypass, addressing various cultural and historical challenges, and choosing the type of bridge involved an interagency partnership and consultation with local Native American tribes. The article contains quotes by Administrator Mary Peters, introducing various safety, congestion, environmental, and security problems with the existing road over the dam. Funding is a mix of Federal and State monies.	36
Putting the Pieces Together by Dan Sunde Washington State's safety management system helps communities to reduce crash rates and save lives. Although the original ISTEA mandate was later repealed, the Washington State Department of Transportation (WSDOT) embarked on a mission in 1991 to develop a manual to help local agencies implement SMS's, known as a local agency safety management system (LASMS). WSDOT designed the LASMS manual as a tool to help local agencies take a broader approach to transportation safety and design projects that would prevent and reduce the number and severity of roadway collisions, transportation-related injuries, and property damage.  According to WSDOT, an LASMS should have two primary components: a local SMS committee and an eight-step transportation safety decision-support process. The manual contains information on the tools and processes needed by local agencies to implement these two components, including a list of the positions that should be represented on the SMS committee, a description of steps involved in developing a comprehensive safety policy, and information on the data elements needed to identify high-collision locations.	40
Where the Rail Meets the Road by Tracy N. Busch and Keri A. Funderburg A tunneling method used in Russia to run a highway beneath a train track could prove beneficial in the United States in some situations. Engineers in Perm, Russia, chose to tunnel under railroad tracks to construct a new road for vehicle traffic, and U.S. transportation officials from FHWA and Kentucky visited Perm to view the tunnel. The Russians opted for the tunnel instead of an overpass or an at-grade crossing to avoid disruption of rail traffic during construction. They also believe that tunnels offer safety and economic advantages over bridges, which require more land, and economic benefits compared with at-grade crossings, which disrupt vehicle traffic. The article describes the safety and technical aspects of constructing the tunnel and concludes with possible applications in the United States, mentioning the safety, cost, and drainage issues that would need to be addressed.	44

No. 6, May/June 2003

Avoiding Voids by Thomas E. Lefchik, L. Rick Ruegsegger, and Robert W. Henthorne Abandoned mines jeopardize the transportation system and public safety, but States are addressing this underground threat. The authors open by describing several incidents involving abandoned underground mines, including a sinkhole that appeared on I-70 in Ohio in 1995. This incident resulted in formation of the Interstate Technical Group on Abandoned Underground Mines (ITGAUM) in 1997. ITGAUM's members today include FHWA, 15 States, a turnpike authority, Canadians, and other groups. ITGAUM has held four workshops since then to explore ways to use modern technologies to locate, assess, and repair mines beneath roadways. The article explores the extent of the problem, providing examples from Pennsylvania, Missouri, and Ohio. The authors conclude by describing other related activities, such as development of a manual by ODOT, a FHWA Web site, and creation of a TRB subcommittee.	2
Proactive Approach to Safety Planning by Roger Petzold The annual death toll on our Nation's highways remains unchanged, but safety-conscious planning may be the answer. Safety-conscious planning (SCP) may be the answer to the static traffic fatality and injury numbers. The article opens with quotes by Mineta and Peters. The author then defines SCP by listing the range of activities that might be included and the requirements needed to implement it. Next, the article provides State examples of SCP activities-from Iowa, Michigan, and Oregon. Finally, the article describes the TRB multimodal SCP working group's activities (a publication and forums).	6
Walls of Fame by John J. Sullivan IV States share successful strategies for partnering with the public to design aesthetically pleasing noise barriers. This article focuses on the aesthetic qualities of noise barriers rather than their technical effectiveness at reducing noise. The author discusses ways to involve the public in making decisions about the appearance of the barriers, cost of aesthetic treatments, materials, and construction techniques for aesthetic treatments, using case studies from Arizona, Pennsylvania, and Washington State. A sidebar discusses the issue of traffic noise in general, the major mitigation techniques, and FHWA's handbook on noise barrier design. Another sidebar discusses sample costs for aesthetic treatments, and a third sidebar compares the advantages and disadvantages of common barrier materials.	10
Lessons Learned by Tianjia Tang and Steve Tonjes A major highway reconstruction in Orlando, FL, provides clues on how to streamline environmental studies. The EIS process for the reconstruction and extension of the John Young Parkway in Orlando, FL, provides several clues for streamlining the environmental study process. The authors' first advice is to start with a solid transportation needs analysis that discusses the problems the project is expected to solve. The John Young Parkway process started with thorough modeling of needs, and this process and the NEPA process were integrated, reducing the time involved and enabling fatal flaws to be identified early. The second lesson learned was the importance of teamwork. In the JYP project, the project engineer and environmental scientist each had to agree on project scheduling, engineering design, cost, and the environmental reports. The third was to employ a concurrent review process to avoid down time between review and resubmit phases. The fourth lesson learned was to smooth the public involvement process by paying special attention to mandatory requirements such as timing of the public meeting. Also pay attention to the public's substantive needs such as the right-of-way acquisition and driveway connections to businesses (e.g., take advantage of the expertise of a right-of-way specialist and subdivide controversial issues until you can find common ground). Lastly, pay attention to the public's emotional needs by working proactively with advocacy groups. The final lesson learned was to think outside the box. In the JYP process, the team sought help from FHWA's Civil Rights Team to deal with one potentially explosive issue. I've added a short version of this summary as a "Results at a Glance" sidebar that will go early in the article, and I'm working on obtaining an endorsement-type quote that will also go in the beginning (placeholder marked).	18
The Man Who Changed America, Part II by Richard F. Weingroff President Eisenhower achieved his Grand Plan for the Interstate System with passage of the Federal-Aid Highway Act of 1956—but his interest in the new highways didn't end there. This continuation of the interstate story has been condensed to run the same length as Part I. The author begins with a 400-word recap of the defeat of the first interstate bill, enough for readers to remember or figure out what is happening. The story then picks up in 1956 with Ike's State of the Union and budget messages, the search for a funding mechanism for the interstates, the mounting support for the Federal Highway Act of 1956, and the ultimate passage of the Act. The author then turns to the Act that created the position of Federal Highway Administrator and the appointment of Administrators Tallamy and Volpe. The narrative continues with the early days of construction of the Interstate System, including discussion of funding problems and Ike's belated discovery that the system included urban freeways. Then comes a description of Eisenhower's attempt to convince the Soviet Premier Khrushchev of the superiority of the modern U.S. highway system. This is followed by the tax increases to keep the interstate program on schedule during the final days of Eisenhower's presidency. After he left office, his interest in the interstates continued, and the author's wrap-up includes mention of a Reader's Digest article on the interstates that greatly alarmed Eisenhower by describing "corrupt land deals and contracts, shoddy construction, and government officials ‘on the take. Sidebars deal with the place of Ike in history and civil defense.	22
A Lifeline Link by Sybil E. Hatch After the wake-up call of the Loma Prieta earthquake, which rocked the San Francisco Bay area in 1989, Caltrans is building what may be the strongest bridge in America. The collapse of the east span of the San Francisco-Oakland Bay Bridge during the earthquake of 1989 triggered a flurry of activity by Caltrans: major seismic upgrades of bridges in the area and rebuilding of the east span to make it perhaps the strongest bridge in America. It will be a self-anchored suspension bridge and the largest public works project in California history, and it will be designed to withstand an earthquake so severe that it is expected to occur only once every 1,500 years. The article describes the seismic safety advances that will help this monumental structure absorb shock, the construction to date, and environmental protection measures.	38
A Benchmark for Livable Progress by Robert B. King Transportation finds common ground with environmental, economic, historic, and community concerns in northern Delaware. The author describes a new Delaware transportation project in Wilmington that is combining transportation improvements with addressing environmental, economic, historic preservation, and quality of life concerns. The catalyst was the merger of two firms to form AstraZeneca, the third largest pharmaceutical company in the world. Delaware's DOT, Department of Natural Resources, and Economic Development Office worked together with 125 representatives from environmental groups, historic preservationists, business leaders, and area residents to develop a master plan that includes a roadway network that separates regional from local traffic and a trail system for pedestrians and bicyclists; wetland preservation and creation, stream restoration, management of stormwater runoff, and seeding of meadows; preservation of the historic Blue Ball Dairy Barn and an archaeological site; two parks with recreational amenities; and landscaping and a public art process.	42
The Fast Lane to Innovation by Marci Kenney and Amy Stearns University Transportation Centers provide our Nation with an effective vehicle for transportation progress. After a general introduction, this overview of the University Transportation Centers (UTC) program provides a brief history of the Congressional authorization for the UTCs. The authors then describe UTC grant work in 7 areas. Under safety, for example, the UTC in Alabama is studying more effective ways of identifying drivers with diminished physical capabilities, specifically poor vision. The Rhode Island UTC is researching quantification of driver distraction from use of cell phones. Under security, the Mineta Transportation Institute in California has published five research reports on transportation preparedness, including 14 detailed case studies of major attacks and 9 vulnerability assessments of major bridges, tunnels, and transit agencies. In addition, MTI has compiled a running chronology of every reported attack on a surface transportation system that has occurred worldwide since 1920. Finally, it has hosted four national symposia on transportation security summarized on TransWeb, the MTI Web page. Researchers at the Southeastern Transportation Center, University of Tennessee, conducted additional work focusing on the risks of terrorism-related cargo passing through intermodal freight terminals. Having assessed the potential risks at seaports, air cargo facilities, and rail-truck intermodal terminals, they published their findings in a report that is being shared with transportation officials to increase awareness and solicit recommendations for security improvements. I have included detailed summaries of the sections on security, but the authors also describe UTC grant work in the following areas: organizational excellence, mobility, economic growth, and human and natural environments.	46
