What Price Congestion Management?
Congestion pricing--the idea that, when more people want to use a road, they should pay (or pay more) for the privilege--was dismissed in the 1950s and rejected in the 1970s in the U.S....
High Level Radioactive Waste Management 1995
The proceedings of the Sixth Annual International Conference on High Level Radioactive Waste Management, held on April 30-May 5, 1995, Las Vegas, Nevada, continues a concerted effort to...
A Safer Earthquake Design Code After NorthRidge
Three recent killer California earthquakes have demonstrated serious deficiencies in our current building codes. As they do after all such events, officials in California and other states...
Is Virtual Reality for Real?
Virtual reality, an advanced visualization technology, will change certain aspects of civil engineering. The method allows people to simulate conditions, render designs and test these...
Bridge Design: Reality Bites Back
Many bridge engineers tend to ignore the process nature of reality, the fact that everything in this universe changes from moment to moment. When they are given the responsibility for...
