Along the Road

"Along the Road" is a hodgepodge of items of general interest to the highway community. But this is more than a miscellaneous section; "Along the Road" is the place to look for information about current and upcoming activities, developments, and trends. This information comes from Federal Highway Administration (FHWA) sources unless otherwise indicated. Your suggestions and input are welcome. Let's meet along the road.

Policy and Legislation

Peña Sends Scenic Byways Report to Congress

Secretary of Transportation Federico Peña recently delivered a report to Congress recommending the establishment of a permanent National Scenic Byways Program beginning on Oct. 1, 1994. The Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA) authorized an interim grants program. The report was prepared by the NationalScenic Byways Advisory Committee and proposes minimum criteria for nominating highways for designation as National Scenic Byways and All-American Roads. All-American Roads, described in the report as roads with "such stunning intrinsic values that both domestic and international travelers will enjoy exploring them," will be the highest class of National Scenic Byways. "This program is voluntary. No agency or organization will be required to participate; those that decide against doing so will suffer no penalty," Peña said. However, the interim grants program has provided $10 million annually to states to use on existing byways or to develop state programs. The U.S. Travel Data Center estimates $1 billion is spent by tourists annually on scenic byways; with about 35,000 miles of scenic highways that means a mile is worth almost $30,000. Any individual, organization, tribe, or agency can nominate a road as a National Scenic Byway, but the nomination must be submitted through the appropriate state agency (usually the state department of transportation, but in some cases the state tourism agency). The nominated road must have significant intrinsic value in one or more of the following categories: scenic, historic, recreational, cultural, natural, and/or archeological.

"Parking Cash-Out" Legislation Drafted

FHWA and the Federal Transit Administration have recommended legislative language to provide federal employees with the option of receiving an equivalent cash allowance or transit fare in lieu of a parking subsidy where free or partially subsidized parking--with a lease or market value of $80 or more per month--is provided. The parking cash-out program strives to transform the tax exemption for employer-provided parking into a reward to encourage commuters to ride transit, carpool, telecommute, or find some other way to work. Employers participating in the program would be able to claim the costs of providing the cash-out allowance (both administrative and actual payout) as a tax deduction. Employer-owned parking and businesses with fewer than 25 employees would be exempted from the program requirements.

United States and Canada Sign Safety Ratings Agreement

The long-awaited agreement between the United States and Canada on reciprocal recognition of motor carrier safety ratings was signed at the North American Transportation Summit on March 25, 1994. This agreement will serve as an umbrella document for future agreements on reciprocity and information sharing.

Metric Signing for Highways Delayed

Public opinion and a congressional prohibition against using federal funds to convert signs to metric terms have caused FHWA to delay implementation of metric traffic control sign legends until after 1996. In the interim, the agency will develop nationwide standards and guidelines for the signs.

Management and Administration

Federal Lands Highway Office Focuses on Native American Needs and Activities

Several recent activities reflect FHWA's commitment to address the highway transportation needs of Native Americans. For example, FHWA, which certifies all Indian Reservation Road programs of the Bureau of Indian Affairs (BIA), reviewed the program of the BIA Portland, Ore., Area Office. In Albuquerque, FHWA representatives participated in discussions on a broad range of tribal issues including infrastructure and transportation. In North Dakota, FHWA took part in the State/Tribal Transportation Planning Conference to discuss awareness of transportation issues on Indian reservation lands and to gather tribal input on the state transportation plan. FHWA also participated in a joint meeting between the Department of Housing and Urban Development (HUD), BIA, and the Navajo Nation on the quality of roads and streets designed and constructed by HUD to serve Indian housing projects. Also, Federal Lands Highway Office representatives attended the first annual Intertribal Transportation Association national conference, which was held in March in Denver; the theme of the conference was "Pathways to Progress--A National Tribal Transportation Summit."

Baltimore Gets Pilot Urban Youth Corps Program

On May 25, Federal Highway Administrator Rodney E. Slater and Baltimore Mayor Kurt Schmoke announced the establishment of a transportation-oriented Urban Youth Corps in Baltimore's Sandtown-Winchester neighborhood. FHWA will provide $250,000 for the pilot program authorized by the National and Community Service Trust Act of 1993. Corps members will be paired with skilled laborers to receive job training in street maintenance, road and sidewalk construction, demolition, landscaping, and other skills. This one-year program, which is expected to become a model for other communities, will provide hands-on work experience coupled with support services for disadvantaged youth and young adults, ages 16-25. It will provide opportunities for the participants to develop marketable skills and to assist in the rehabilitation of transportation facilities in Sandtown-Winchester. The program was developed by FHWA, the Maryland State Highway Administration, the Department of Public Works in Baltimore City, and the Baltimore-based Community Building in Partnership.

Technical News

Chicago Authorizes New Downtown Signal System

The city of Chicago recently let a $2.24-million project for a new Central Business District Signal System for 73 intersections in the downtown area. The new system will feature state-of-the-art controller equipment with remote monitoring and timing capabilities.

United States, Canada Conduct Vehicle Load Research Project

FHWA signed an agreement with Transport Canada to participate in a research project on securing commercial vehicle loads. This study of load-securement systems will result in the development of principles for securing loads on heavy trucks; these principles could contribute to a revised international standard. The project is a public-private, U.S.-Canadian effort. Funding is provided by FHWA, Transport Canada, New York State, various Canadian provinces, the American Trucking Association, the Canadian Trucking Research Institute, and the Canadian Council of Motor Transport Administrators.

FHWA and NPS Win Engineering Award for Segmental Arch Bridge

FHWA's Eastern Federal Lands Highway Division and the National Park Service received one of seven Grand Awards in the 1994 Engineering Excellence Awards Competition sponsored by the American Consulting Engineers Council. The award was given for the Natchez Trace Parkway segmental arch bridge over Tennessee Route 96.

Green Box Development Begins

New Mexico's State Transportation Authority is funding a $500,000 effort to develop sensor technologies to monitor rail cars and cargo. The sensors, mounted in an impact-survivable container, called a "green box," should improve rail safety and make rail commercial transport a more attractive alternative.

Soil Nail Wall Design Specifications Are Being Revised

Development recently began on the finite-element analytical models and laboratory calibration tests needed to begin preparation of American Association of State Highway and Transportation Officials (AASHTO) design specifications for soil nail wall shotcrete facings. This project is a cooperative effort between the Federal Lands Highway Office, the Office of Technology Applications, and Region 10; it will produce design and construction specifications, guidance, and project assistance for soil nail walls.

AASHTO Is Developing a QC/QA Guide Specification

The Joint Materials/Construction Task Force on Quality Control/Quality Assurance (QC/QA) met in Little Rock, Ark., to develop a draft AASHTO QC/QA Guide Specification. The draft specification is being sent to the Construction and Materials subcommittees and to industry for comment. Then, the revised draft will be considered for inclusion in the next edition of the Construction Subcommittee's Guide Specifications.

Traveler Information Systems to be Used During '96 Olympics

The Georgia Department of Transportation (DOT) is placing Intelligent Vehicle-Highway Systems (IVHS) Advanced Traveler Information Systems (ATIS) in two welcome centers to be constructed before the 1996 Olympic Games. Regional and state personnel are working with the Georgia Department of Industry and Trade and the Atlanta Committee for the Olympic Games to develop displays and interactive systems that will enable visitors to access information about traffic conditions, Olympic venue times and locations, recommended travel routes, and dining and lodging. The system will also tie into the public transit system via information kiosks at Olympic game sites and at rapid transit depots. These services provided for visitors to the Olympics are part of a larger project to test a metro-wide traveler information system; partners in the test are Scientific-Atlanta, Federal Express, TRW, Concord Associates, Georgia Tech Research Institute, Georgia Institute of Technology, Clark Atlanta University, Georgia DOT, Oak Ridge National Laboratory, the Atlanta Committee for the Olympic Games, and FHWA.

Smithsonian Officials Consider IVHS Exhibit

Representatives of the FHWA IVHS Office staff and IVHS AMERICA met with officials of the Smithsonian Institution's National Museum of American History and the IVHS community. The purpose of the meeting was to brief the Smithsonian officials on the national IVHS program and provide ideas for an IVHS exhibit. Smithsonian officials are considering adding an IVHS module to their ongoing Information Age exhibit.

Fourth IVHS AMERICA Convention Is Largest Yet

More than 3,500 transportation experts--government officials, business executives, engineers, scientists, and academicians--from around the world attended the IVHS AMERICA annual meeting held last April in Atlanta. During the four-day meeting, 62 presentations and panel discussions focused on the use of advanced communications, electronics, and computer technologies in vehicles, highways, and public transit systems. Senior U.S. DOT leaders--including Secretary of Transportation Federico Peña, FHWA Administrator Rodney E. Slater, and Federal Transit Administrator Gordon J. Linton--addressed the participants. The meeting also featured 118 exhibitors demonstrating the latest intelligent vehicle-highway systems, products, and services. For example: Rockwell introduced a traffic sensor for monitoring traffic flow, an automatic vehicle location system, and an in-vehicle navigation/route guidance system. GTE Personal Communications Services and Navigation Technologies demonstrated new traveler information and safety applications--including turn-by-turn driving instructions to a desired destination--using Cellular Digital Packet Data technology. Sony introduced a Global Positioning System-based invehicle mobile navigation system that uses Etak software with information stored on CD-ROM disks and displayed on the unit's five-inch color LCD screen. Also, during the convention, Lawrence D. Dahms, executive director of the Oakland, Calif., Metropolitan Transportation Commission, was installed as chairman of the IVHS AMERICA Board of Directors and four new members were elected to the board.

IVHS Discussed at North Carolina A&T State University

Staff from the FHWA Office of Traffic Management and IVHS made a presentation on IVHS to students at North Carolina A&T State University as part of that school's 1994 Transportation Lecture Series. FHWA's North Carolina Division is helping to sponsor this lecture series and other activities at the school as part of FHWA's continuing commitment to develop and use the expertise of the nation's historically black colleges and universities.

States Kick Off New Safety and Awareness Campaigns

South Carolina and Maryland recently began new large-scale public information campaigns. Both are conducting campaigns to deter red-light running. South Carolina filmed two public service announcements on this theme; Maryland's campaign is being supplemented by integrating more and longer all-red phases into the state's signal system. South Carolina also recently introduced MILES, an animated section of traffic stripe that "comes to life" to inform the public on traffic safety issues. Finally, Maryland is administering a multiyear campaign to educate motorists on safely sharing the road with large commercial vehicles. The campaign introduces a new term to highway safety--the "No Zone." The No Zone refers to the various blind spots and other "accident-prone" areas around commercial vehicles.

Region 1 Educates Driving Educators

Many operational characteristics and features of the highway are known only within the highway industry. Drivers might behave differently if they knew more about the "forgiving" highway and the silent factors of highway safety: for instance, an uninformed motorist might end up in a rollover accident in trying to avoid a breakaway sign support. To convey this type of information, Region 1 recently gave a short course on roadside safety features to New Hampshire driving education instructors; the course might later be developed for continuing use in the driver ed curriculum.

ASCE Supports Continuing Education for Relicensing

ASCE, America's oldest national engineering society, is working to make continuing education a condition for the relicensing of civil engineers nationwide and to make continuing education requirements uniform in states that already mandate continuing education as a prerequisite to relicensing. ASCE's position reflects a trend in many professions toward stronger educational requirements for association membership, licensing, and relicensing. "ASCE has responded to the rising demands of practicing engineering in a global environment where the rate of change in technology and business is rapidly accelerating," said James W. Poirot, ASCE president. State and federal engineering regulations, for example, are rapidly expanding. New engineering technologies, such as software and advanced composites, have exploded, requiring intensive and continuous learning. "The volume of even basic knowledge for civil engineers to stay current is growing at an unparalleled rate," Poirot said. "Civil engineers hold a sacred public trust. ... Public opinion polls reveal that consumers rank engineers among America's most respected groups. But to maintain that trust, like all professions, civil engineering faces a dramatic and prolonged period of transition. The world is turning faster, and civil engineering must move with it."
