"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.
DOT Will Reorganize
Secretary of Transportation Federico Peña announced Feb. 2 that the U.S. Department of Transportation (DOT) will consolidate from 10 agencies to three: the Federal Aviation Administration (FAA), U.S. Coast Guard, and a new Intermodal Transportation Administration. Peña said the new organization fosters intermodalism; streamlines programs and operations by eliminating duplicative functions; preserves customer linkages; and strengthens connections between safety, infrastructure, and construction activities. Under the restructuring plan, the Intermodal Transportation Administration will combine the functions of a majority of the current DOT agencies, such as FHWA, Federal Transit Administration, Federal Railroad Administration, and National Highway Traffic Safety Administration. The FAA will maintain jurisdiction over aviation safety, regulation, and certification; its air traffic control operations will become an independent governmental corporation. The Coast Guard will maintain authority over maritime navigation, communication, and safety standards. Peña projects that the streamlined DOT will save $6.4 billion in budget outlays over the next five years.
Agreement Authority Delegated to Regions
In December, Federal Highway Administrator Rodney E. Slater approved a memorandum that authorizes FHWA regional administrators to enter into cooperative agreements with the state departments of transportation to carry out specific research and development projects. The memorandum also permits this authority to be redelegated to the division administrators. This action was taken to encourage the use of cooperative agreements, streamline procedures, and empower employees.
EPA Reverses Position on NOx Waivers
Deferring to State Implementation Plans (SIPs) in dealing with downwind pollution, the Environmental Protection Agency (EPA) decided to abandon consideration of the downwind transport issue when deliberating over exemptions to the nitrogen oxides (NOx) requirements of the Clean Air Act. Agency attorneys have apparently ruled that the only mechanism for regulating the downwind transport of pollution and the controls dealing with it are SIP matters. This should allow EPA to act more quickly on NOx waiver requests and provide some relief to areas that are having difficulty meeting the NOx conformity test.
Vision Waivers Validated Until March 1996
On November 17, FHWA announced in the Federal Register its "Final Determination," which validates waivers issued to certain drivers of commercial motor vehicles from the date of this notice until March 31, 1996. This action is directed solely at the 2,399 drivers who have been granted temporary waivers to participate in the previously authorized vision waiver study. This action follows, and is consistent with, the decision of the U.S. Court of Appeals for the District of Columbia Circuit in this case; the court vacated the rule authorizing the temporary waivers and remanded the matter to FHWA for further action.
NHS Is Back in Congressional Committee
At press time, the National Highway System bill was under consideration by the Committee on Transportation and Infrastructure in the U.S. House of Representatives. Although the bill was passed by the House Sept. 23, the bill died in the 103rd Congress without Senate action. Therefore, the bill must be reintroduced through the committee in the 104th Congress, which convened in January.
ZEVs Proposed as State Option
EPA's tentative approval of the Northeast Ozone Transport Commission (OTC) low-emission vehicle (LEV) petition was announced in a September 13 Federal Register notice. The proposed rule, however, left open the requirement for the region to pursue a zero-emission vehicle (ZEV) as part of their strategies. The only type of automobile capable of complying with ZEV standards today is the electric vehicle. The automobile industry has been unyielding in its stance against ZEV mandates, as manufacturers contend that the electric vehicle is far from production ready. The OTC LEV program is patterned after California's approach although ZEV sales are a requirement of California's strategy.
Auto Industry Opposes OTC LEV Program
The governors of Michigan, Ohio, and Wisconsin sent a letter to EPA opposing the petition by the Northeast OTC that promotes a California-style, low-emission vehicle program. The governors also stated their desire for the EPA to continue dialogue with the automobile industry geared toward the development of a federal LEV program. The letter emphasizes the "severe negative ramifications" on the auto industry if the OTC request is upheld. The governors also point out that the nationwide approach behind the "Fed LEV" program would yield equivalent reductions in hydrocarbons and nitrogen oxides if more affordable and cleaner cars are marketed throughout the country instead of higher priced vehicles in California and the Northeast.
Peña Urges Support of Mexican Financial Initiative
Secretary Peña urged U.S. transportation companies operating in Mexico to support President Clinton's initiative to help steady the Mexican economy. In a Feb. 1 letter to airline, railroad, and trucking companies, Peña said, "Millions of American jobs and the health of hundreds of American industries depend on cross-border trade and expanding exports encouraged under the North American Free Trade Agreement."
Nine States Agree to Streamline Hauling
Nine states -- Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, North Carolina, Tennessee, and West Virginia -- agreed to allow specialized haulers to move under one document instead of a separate document from each state. Permits are limited to vehicles no heavier than approximately 55,000 kilograms, no wider than 4.25 meters, and no longer than 30.5 meters.
ITS Public/Private Institutional Issues Discussions
The FHWA Intelligent Transportation System (ITS) Joint Program Office hosted a meeting of experts from the public and private sector to discuss key institutional issues in "shared resource" arrangements for installing telecommunications technologies in highway rights of way in exchange for system access.
New York Will Expand Urban Youth Corps Program
Recently, Federal Highway Administrator Slater and New York State DOT Commissioner John Egan participated in a ceremony at LaGuardia College that recognized members of New York DOT's Green Team. The Green Team program provides education and jobs on state highway projects to disadvantaged young people in the New York City area. FHWA will fund some of these activities under the Urban Youth Corps Program. New York DOT plans to expand this program to several cities in upstate New York.
Alabama Set to Launch Urban Youth Corps Program
An Urban Youth Corps Program in Birmingham, Ala., will train 32 horticulture and urban forestry technicians and eight horticulture and urban forestry interns. Two nine-month training sessions for 20 youths are planned. The city will match the federal funds, develop the landscape projects, hire and train the youths, report on the accomplishments of the program, and make recommendations to improve the program.
Intermodal Agreement in Florida Is Signed
The Florida DOT, Metro-Dade County Metropolitan Planning Organization, Metro-Dade Transit Authority, Federal Transit Administration (FTA), and FHWA are partners in the "Memorandum of Agreement (MOA) for the Miami Intermodal Center/State Route 836 Corridor Study." The MOA documents each agency's concurrence that ongoing studies will satisfy the Major Investment Study (MIS) and Environmental Impact Statement (EIS) requirements of FTA and FHWA. The MIS/EIS will ensure that highway, transit, and multimodal alternatives are developed through a single, integrated process.
Oldest Village in the Southwest Discovered
A village settled by Native Americans between 400 and 200 B.C. was discovered by archaeologists conducting a study for Arizona DOT in connection with the reconstruction of the Miracle Mile traffic interchange on Interstate 10 near Tucson. The village is the oldest near-complete settlement found in the Southwest. It includes nearly 200 houses, several storehouses, and one "big house," believed to be either a chief's house, a room for religious rituals, or a meeting room for village elders. The discovery will change the way the Arizona DOT approaches archaeology in the future for some parts of the state. There may be more extensive excavations at sites near major waterways as a result of this discovery.
Northridge Earthquake Repairs Are Completed
On Nov. 4, Federal Highway Administrator Slater joined California Governor Pete Wilson and others to officially open the last remaining transportation link damaged by the Northridge earthquake. With the reopening of the connector between I-5 and state Route 14, 100 percent of the main-line traffic capacity has been restored to its pre-quake condition. The ceremony marked the close of an unprecedented road repair effort less than 10 months after the second most costly disaster in American history.
Louisiana Goes High Tech in Pavement Inspections
The Louisiana Department of Transportation and Development (DOTD) is modernizing the way in which DOTD collects information to determine which roads should be fixed. DOTD is spending about $500,000 to hire Roadware, Inc., to drive a sophisticated motor vehicle up and down Louisiana highways to collect data continuously at highway speeds to determine pavement condition, rutting, roughness, grade, curve, radius, pavement width, and more. The vehicle is equipped with special video cameras that automatically record the location of the cracks and potholes and allow engineers to schedule maintenance and repair more efficiently. Without leaving the office, traffic planners can measure the width of a road to determine if a passing or a turning lane should be added. For years, DOTD has relied solely on 30 workers statewide, with clipboards in hand, to determine which parts of the state's nearly 27,000 kilometers of paved roads should receive attention.
Maglev Test Track Opens in Florida
American Maglev Technology of Florida Inc. held a groundbreaking ceremony in October for a new magnetic levitation (maglev) test track south of Daytona Beach on Florida's east coast. American Maglev officials plan to build a 3.2-kilometer linear track at the site to test maglev technology. They are currently seeking funding for a $3.5 million test project. American Maglev scheduled preliminary work with the test vehicle on the track in December 1994 and full-blown test runs beginning mid-January 1995.
Alaska Has an "Eagle Eye"
As part of the environmental study for proposed road alignments out of Juneau, the Alaska DOT needed to precisely locate bald eagle nests along both sides of the Lynn Canal, a rugged 110-kilometer-long fjord with steep cliffs and glaciers running directly into the sea. A new high-tech solution located 118 nests using helicopters, video cameras, and satellites. The helicopter reconnaissance crew hovered for 10 seconds directly over each nest that had been identified by a U.S. Fish and Wildlife Service spotter. The pilot used the camera to accurately position the helicopter while the onboard satellite receiver recorded the latitude and longitude of each nest within 3 meters. These locations were then transferred to project contour maps, and future road locations and specifications will be designed around the nests. This new process was very successful and only cost a third of a normal survey.
Major ITS Operational Test Under Way in Chicago
The ITS operational test "ADVANCE" in the northwest Chicago suburbs is the largest test of its kind. Approximately 3,000 vehicles are being equipped with a Global Positioning System (GPS)-based, invehicle navigational computer and screen unit that will guide drivers with turn-by-turn directions to the intended destination. The recommended route is based on current roadway conditions continuously beamed into the vehicles. This operational test is set apart from others by the large number of vehicles involved and because these vehicles provide the measure of the quality of traffic flow. Furthermore, the equipped vehicles are owned by residents and businesses and are being used for everyday commercial activities, commuting, shopping, and pleasure.
Las Vegas Airport Connector Opens
The grand opening of the Las Vegas McCarran International Airport Connector was held Dec. 31. The connector ties the Las Vegas Beltway and I-15. The project was funded from Passenger Facility Charges. Connecting air and ground transportation, this project is truly an intermodal project.
Oregon Saves With Red Light-Emitting Diodes
Oregon DOT has completed an evaluation of light-emitting diodes (LED) used as traffic signals. Oregon DOT has concluded that significant savings can be achieved in operating costs and increased life by converting incandescent lamps for the red ball, the red arrows, and the orange pedestrian hand symbol to LEDs. Although the initial cost to convert is between $200 and $400, the conversion pays for itself over time because the energy use of LEDs is 50 percent less than incandescent lamps and the life expectancy of LEDs is 10 years compared to one year for incandescent lamps.
Rental Cars Are Getting Smarter
Avis Rental Car Company announced Sept. 14 that it will be installing an invehicle navigational system and a "panic button" in 500 Oldsmobiles by Dec. 31. The cars will be offered in California, Florida, and Michigan; Florida will receive about 200 cars for the Miami area. The "panic button" feature allows the driver to instantly notify police of trouble by pressing a button mounted next to the cellular phone. The signal is automatically routed via computer to the nearest police department. The location of the automobile is concurrently pinpointed by satellite and forwarded to the police within 30 seconds. The invehicle navigational system is called Guidestar and consists of a 10-centimeter computer screen with interactive keys to program destinations. The screen tracks the vehicle's movements and a voice indicates required turns.
Australians Develop a Walking Profilometer
The Australian Road Research Board (ARRB) has lodged a worldwide patent application for the "walking profilometer." The walking profilometer can record up to 100 accurate point height measurements in 90 seconds on a newly paved surface. The surface profile is measured at 250-millimeter intervals with an accuracy of up to 0.02 millimeters height per meter of travel at operating speeds of up to one kilometer per hour. ARRB touts the accuracy, portability, and ease-of-use of this instrument, particularly in applications in normally inaccessible areas such as bridges, parking lots, footpaths, warehouse and factory floors, and airport runways.
HITEC Completes First Year
The Highway Innovative Technology Evaluation Center (HITEC) completed its first year of operation in January. HITEC is now evaluating 20 new products that could make America's highways safer and more durable. Technologies being evaluated include a pothole patching compound, a nuclear gauge to measure the ratio of water to cement in fresh concrete, a post-tensioned concrete segmental bridge system, a sight and sound wall, an innovative sign system for use in glare-prone areas, and seismic isolation and energy dissipation devices for highway bridges. During the first year, much emphasis was placed on gaining public sector participation and endorsement of the HITEC process. As HITEC moves into its second year, emphasis is being placed on the expeditious completion and acceptance of evaluation reports.

ACEC Selects Top 12 Bridges
The American Consulting Engineers Council (ACEC) selected 12 bridges as the most spectacular bridges in the United States. Selection criteria included innovative design, degree of challenge in design, unique size or appearance, and aesthetic appeal. "Consulting engineers are uniquely qualified to judge America's best bridges -- not only because we design bridges for a living, but also because we understand the sheer beauty and strength inherent in these structures," said Les MacFarlane, president of ACEC. The top 12 include new bridges -- the Clark Bridge in Alton, Ill. -- and old bridges -- the 153-year-old Wire Bridge in New Portland, Maine. The list includes well-known bridges -- the Golden Gate and Brooklyn bridges -- and lesser known bridges -- the Houston Ship Channel Bridge, the Glenwood Canyon I-70 Bridges in Colorado, the Tom Moreland Interchange in Atlanta, the Yaquina Bay Bridge in Oregon, the Father Louis Hennepin Bridge in Minneapolis, the Roosevelt Lake Bridge in Arizona, the Rainbow Bridge in Niagara Falls, and the James River I-295 Bridge in Virginia.
BBC Films Excavation of Indian Site in Iowa
On Oct. 28, the British Broadcasting Company was in Iowa to film the Native American archaeological excavations near U.S. Route 61. The excavations were necessary to upgrade U.S. 61 to a four-lane expressway in southeast Iowa.
Briefing Outlines Barriers to ITS
Cambridge Systematics presented a briefing Jan. 6 on the U.S. DOT-sponsored research, "Overcoming Barriers to IVHS (Intelligent Vehicle-Highway Systems) -- Lessons from Other Technologies." The briefing reviewed deployment of technologies such as cellular telephones, cable television, and electronic funds transfer, as well as other technologies implemented in recent years. Candidate models that could be useful to Advanced Traffic Management Systems and Advanced Traveler Information Systems were examined.
Cellular Phones Help Nab Drunk Drivers
After six months of a statewide campaign to encourage drivers to report hazards and incidents via a toll-free cellular phone number (*FHP), the Florida Highway Patrol (FHP) reports an 11 percent increase in drivers reportedly driving under the influence (DUI) of alcohol or drugs and a 16 percent increase in DUI arrests. This program began in April 1994, when the FHP and the Florida DOT, working with the major cellular phone companies, established a statewide emergency cellular phone number for reporting traffic accidents, suspected drunken drivers, stranded motorists, or suspicious incidents. The Florida DOT erected white-on-blue signs with the message "Florida Highway Patrol -- Dial *FHP" at every state and county line on the interstate highways and other major roads at approximately 48-kilometer intervals. The calls are routed to the nearest FHP station.
Oklahoma Develops a Wetlands Classroom
Wetlands that were mitigated and protected by a highway project in northeastern Oklahoma will be used for an outdoor classroom for students of nearby Oologah Public Schools. Oologah High School science instructors, the Oklahoma DOT, and others reached a long-term agreement for use of highway project lands, including approximately 20 hectares acquired for mitigation of wetland losses on U.S. Route 169. The Oklahoma DOT encourages school officials to enter the area and begin the educational program.
New Hampshire Records 30-Year Low in Highway Fatalities
Highway-related fatalities are at a 30-year low for New Hampshire. This is the third consecutive year that the death toll has dropped. In 1992, the death toll dropped from 145 deaths to 123, and it dropped to 119 fatalities in 1994. Various state and federal agencies are working on aggressive public information and public relations campaigns to target seatbelt use, courteous driving, and avoidance of drinking and driving.
Highway Fatalities in South Carolina Are Down
The South Carolina Department of Public Safety announced that there were 830 deaths on South Carolina's highways during 1994, compared with 845 in 1993. The mileage death rate dropped from 2.3 per 100 million miles traveled in 1993 to 2.2. Several factors were credited for the improved statistics, including increased driver awareness, especially regarding seatbelts.
Media Reports on 10-Ton Killers
Television station WBRZ in Baton Rouge, La., broadcast a three-part special series on the evening newscasts Nov. 3, 4, and 5 entitled "10-Ton Killers." These segments looked at the danger and consequences that big trucks pose on the highways. It looked at several crashes and accidents in the Baton Rouge area during the past few years that caused substantial property damage, injuries, and fatalities. It noted that the safety of the big trucks in general is questionable and cited that recent U.S. DOT inspections placed 26 percent of the inspected vehicles out of service.
Several ITS Technologies Are in Use Now
The November/December issue of AAA World magazine features ITS technologies now available to drivers of commercial trucks, buses, and automobiles: (1) RBDS (Radio Broadcast Data System), which allows FM radio stations to simultaneously broadcast their normal programming and emergency traffic information updates. These reports are displayed in place of the radio station call numbers on a slightly larger-than-normal screen. (2) Radar that warns of potential collision. Greyhound buses are equipped with a front-looking radar that warns the bus driver if the bus is overtaking a vehicle too quickly. (3) Electronic readers to speed up toll collection. (4) Oldsmobile offers a GPS-based autonomous route guidance system (no real-time traffic information) in several states.
