Future Freight
In 21st-century America, most long-distance cargo will be transported via pipelines linking major cities. The most versatile freight pipeline is the capsule variety, which carries cargo...
Bumpy Road Ahead
By 1999, we will be riding on highways and public transit paid for by the 1991 reauthorization of the National Surface Transportation Act. Or maybe we won't. The new bill,...
Transportation: New Systems for the New Century
By the end of this decade, a new coordinated transportation system for the U.S. could consist of high speed rail, maglev, regional airports and highways built solely for trucks. It would...
Seismic Risk Considerations for Transportation Systems
During the recent Loma Prieta Earthquake, major damage to certain key transportation elements greatly affected operations of major transportation systems within the San Francisco Bay Area....
Probabilistic Prediction of Losses to Lifeline Systems Due to Earthquakes
An efficient and practical method for earthquake loss estimation for lifelines is developed, using the recent advances made in the areas of lifeline earthquake engineering and probabilistic...
Research in ASCE's Hydraulics Division
