Eight Steps Toward a "Smarter" National Highway System

by Christine M. Johnson

The Federal Highway Administration has already begun to implement these steps to increase the capacity and efficiency of our existing highway systems.

Congestion Pricing: Reducing Traffic Jams Through Economics

by Ginny Finch

Congestion pricing is a promising concept for reducing gridlock on major highways during peak travel periods and for reducing congestion costs wasted fuel, air pollution, and travel delays.

Performance of Epoxy-Coated Rebars in Bridge Decks

by Jeffrey L. Smith and Yash Paul Virmani

Epoxy-coated reinforcing steel provides effective corrosion protection that can extend the service life of concrete bridge decks.

FHWA Launches New Nationwide Seismic Bridge Design Training

by James W. Keeley

"Seismic Bridge Design Applications" is FHWA's new training course for practicing bridge/geotechnical engineers on "how to" apply the American Association of State Highway and Transportation Officials (AASHTO) seismic analysis and design requirements for different bridge types across the United States.

Aftermath of the Kobe Earthquake

by Hamid Ghasemi, Hisanori Otsuka, James D. Cooper, and Hiroyuki Nakajima

The lessons learned in the aftermath of the Hanshin/Awaji Earthquake in the Kobe, Japan, area on Jan. 17, 1995, have real relevance for the United States. The bridges in central and eastern United States within the seismically active New Madrid Zone are very similar to the types of bridges in the Kobe area, 60 percent of which were damaged by the earthquake.

WesTrack: The Road to Solutions

by Terry Mitchell

WesTrack, a new pavement test track in Nevada, uses four driverless trucks, operating about 20 hours per day, seven days a week, to apply load to its 26 test sections.

Test Roads: Designing the Pavements of the Future

by Terry Mitchell

FHWA and a number of states and other partners are conducting pavement studies, using full-scale test tracks and machines that simulate traffic loads, to gain real-world experience that will result in improved roadway design and construction.

The Promise of High-Performance Concrete

by David C. Smith

The enhanced strength and durability of bridges that incorporate high-performance concrete (HPC) in beams, decks, and piers promise to reduce the lifetime cost and deterioration of these structures. To encourage further research and to promote the use of HPC, FHWA is showcasing HPC in regional events and demonstration projects in the eight states that have become active partners with FHWA by constructing or preparing to construct bridges with HPC.

Intelligent Transportation Systems in Japan

by Hideo Tokuyama

In Japan, intelligent transportation systems are one of several essential elements in creating a global advanced information and telecommunications society.

Smart Road, Smart Car: The Automated Highway System

by Nita Congress

The National Automated Highway System Consortium is making significant progress toward the development of an automated highway system that will combine intelligent transportation systems (ITS) technologies to maximize safety and efficiency and to reduce congestion and associated costs.
