Gore Announces $60 Million More for California's Flood-Damaged Roads
Vice President Al Gore today announced that California will receive an additional $60 million in emergency relief funds for repairs on roads damaged by flooding that began in February 1998.
The $60 million is in addition to $40 million in emergency relief funds that the state received earlier this year to repair roads damaged by heavy rains and flooding, bringing the total this year to $100 million.
The money, which comes from FHWA, was provided in response to the state's request for help to repair federal-aid roads. FHWA money is awarded after a formal emergency proclamation has been issued and the state has filed a preliminary damage assessment for its highways and bridges on the federal-aid system.
The funds reimburse the state for emergency work that is already completed and provides funding for other necessary repairs to correct major or unusual damage to federal-aid highways. Eligible repair work includes reconstructing damaged bridges and pavement surfaces; establishing detours; removing slides and debris; and replacing signs, lighting, and guardrails.
Washington Receives $7.6 Million From FHWA
The state of Washington will receive $7.6 million in emergency relief funds for repairs on roads damaged by flooding that began May 26 and for repair of a fire-damaged bridge.
Of the total, $625,000 will go for work necessary to repair damage to the Carbon River bridge on State Road 165 in Pierce County. The bridge was critically damaged and closed to traffic by a vehicle fire on March 3, 1998. The remaining $7 million will be used for work necessary to repair damage to roads in the counties of Ferry, Stevens, and Pend Oreille.
FHWA Experiments With TMCs
Hundreds of remote closed-circuit televisions (CCTV) are expected to be used in future traffic management center (TMCs) for monitoring the roadway system. FHWA researchers conducted a series of three experiments to evaluate existing and proposed approaches for selecting and controlling arrays of remote cameras.
Operators of these TMCs will have to quickly select appropriate cameras and control their pointing angles, zoom ratio, and focus. Researchers evaluated four basic interface concepts in their experiments: joystick, keyboard, mouse, and touchscreen. They also compared tests involving cameras that moved between pre-programmed pointing angles and cameras in which the operators had full manual control of the cameras.
Operators using a touchscreen interface made significantly more errors when selecting cameras than did those using the other interfaces. When manipulating cameras, operators using a keyboard and mouse were able to manipulate the cameras more effectively than those using a joystick or touchscreen. Cameras with preset pointing angles were found to be significantly more efficient than those with fully manual controllers. Operators using the preset cameras, however, needed a mechanism to fine-tune the pointing angles. Thus, a hybrid approach, in which the camera automatically moves to an approximate position and the operator manually centers the camera on the point of interest, was strongly preferred.
New Superpave Guidance Available
This construction season, Superpave will comprise 30 percent of awarded asphalt tonnage. Two publications, which have recently been published, give detailed guidance on using Superpave: 1998 AASHTO Superpave Lead States Guidance and Superpave Construction Guidelines.
The Lead States Guidance on Superpave Issues, published by the American Association of State Highway and Transportation Officials (AASHTO), provides guidance on how to improve the use of the Superpave mix design provisional AASHTO specifications. It specifically addresses the issues of varying materials and climate conditions.
Superpave Construction Guidelines, published by the National Asphalt Pavement Association (NAPA) under a cooperative agreement with FHWA, explains how to deal with mix production and construction issues involving coarse-graded Superpave-designed mixtures. Both publications are currently available

NLEV Program Is in Effect
The National Low-Emission Vehicle (NLEV) Program, which represents an alternative, more effective method of regulatory development through extensive interaction between the Environmental Protection Agency (EPA) and stakeholders, is in effect after more than three years of debate among automobile manufacturers, state governments, EPA, and other interest groups.
This "cleaner car" program, launched by Vice President Gore early this year, will dramatically improve air quality and protect public health by making cleaner-burning cars available to American consumers. Nine northeastern states - Connecticut, Delaware, Maryland, New Hampshire, New Jersey, Pennsylvania, Rhode Island, Virginia, and the District of Columbia - and 23 auto manufacturers have decided to participate in the voluntary program, which had been debated in the northeast during negotiations for the original Low-Emission Vehicle (LEV) for the Ozone Transport Commission (OTC). Now, with the program in effect, the production and marketing of cleaner vehicles can begin later this year to meet NLEV's stricter emissions requirements for 1999 light-duty cars and light-duty trucks.
Seat-Belt Use Improves
This summer, California was touted as the first state in the nation to achieve a 90-percent seat-belt use rate.
To promote seat-belt use on a national level, President Clinton committed the federal government to leading the way towards increased seat-belt use by signing Executive Order (EO) 13043, "Increasing Seat Belt Use in the United States." The EO requires federal employees on official business to use seat belts when using a motor vehicle.
President Clinton has set the goal of 90-percent seat-belt use nationwide by the year 2005.
DOT Secretary Rodney E. Slater's goal for DOT is to increase federal employee seat-belt use to 85 percent by 2000 and 90 percent by 2005. The plan, developed by the department's National Highway Traffic Safety Administration (NHTSA), has four elements:
If all states maintained an 85-percent seat-belt use rate, annually, more than 4,000 deaths and 100,000 injuries would be prevented. Currently, the national buckle-up rate is 69 percent.
N.J. Electronic Toll Collection Consortium Enters Partnership
The New Jersey Electronic Toll Collection Consortium and MFS Network Technologies entered into a public-private partnership to design and implement an electronic toll collection system called E-Z Pass. The New Jersey Consortium includes the New Jersey Turnpike Authority, New Jersey Highway Authority, South Jersey Transportation Authority, Port Authority of New York, and the New Jersey and Delaware DOTs.
The system is intended to be integrated with similar systems in other states, enabling motorists to drive from Massachusetts to Washington, D.C., without stopping to pay a toll. E-Z Pass is scheduled to be up and running on the Atlantic City Expressway by Nov. 10, 1998, with the New Jersey Turnpike and Garden State Parkway following the Atlantic City Expressway project within 14 months.
CFLHD Awards Design-Build Contract
The Central Federal Lands Highway Division (CFLHD) awarded its first design-build contract to Kiewit Pacific Company. The $33.4 million contract, the largest ever awarded by CFLHD, was awarded to reconstruct El Portal Road in Yosemite National Park, Calif.
The park suffered damage as a result of devastating floods that occurred in January 1997. The emergency repairs were completed in May 1997; the design work began in June; and the physical construction is planned to begin in early September after the heavy tourist season ends. The park received $180 million in flood-recovery money through special appropriations. That money is also paying for most of the design-build project.
New Traffic Management Technologies Featured
New traffic management technologies were unveiled this July as part of TransGuide, an advanced traffic management system developed by the Texas Department of Transportation.
The new projects were introduced under the federal government's Model Deployment Initiative (MDI). This initiative was set up to demonstrate to decision-makers across the nation the value of full integration of an intelligent transportation infrastructure.
Since TransGuide became operational on 42 kilometers of San Antonio highway, this system has reduced accidents by 15 percent and cut emergency response time by 20 percent. The system is expected to expand to 465 kilometers of highways and city streets all around San Antonio.
The new MDI projects include the following:
FHWA Sponsors Winter Maintenance Scanning Tour
FHWA sponsored the second winter maintenance technology scanning tour of Europe this past March. Participants from federal, state, county, and city governments who are responsible for winter maintenance in their jurisdictions within the United States visited local, state, and national road officials in France, Norway, Sweden, and Switzerland.
The purpose of the tour was to examine state-of-the-art developments in winter maintenance technologies used abroad and apply those technologies to the United States. The scanning team studied the following topics:
A report detailing the team's findings will be available fall 1998.
