Houston Moves Forward Again
The National Transportation Plan, as released by Transportation Secretary Samuel Skinner, advocates the construction of toll roads and calls on local governments to devise and finance...

Trouble on the Waterways?
Crumbling highways and bridges can cripple the U.S. economy. A lesser known transportation problem is the condition of our inland waterway system. Waterways are a cost-efficient, environmentally-sound...

Beneficial Use of Coal Ash as a Structural Fill
For decades, electric utility companies have and will continue to dispose of their coal ash in various waste disposal sites. In the state of Pennsylvania, the Beneficial Use of Coal Ash...

Vine Street Reborn
Following decades of controversy and a four-year construction effort that threatened to drive both engineers and local motorists crazy, Philadelphia's Vine Street reopened...

Dallas' Flood Caverns
Dallas' North Central Expressway floods during heavy rains, but the dense development that helps create excessive runoff also precludes large detention ponds. The high-quality,...

How Much Must the Geologic Barrier Contribute to Safe HLW Disposal?
As a prerequisite of a potential repository site, it is important to assess the role of each system component in providing safety and, in particular, to establish the specific geological...

Transportation of Radioactive Materials Routing Analysis: The Nevada Experience
In 1987, the Nevada State Legislature passed a Bill requiring the Nevada Department of Transportation to develop and enforce a plan for highway routing of highway route controlled quantity...

An Approach to Evaluate the Sufficiency of Highway Bridges for Nuclear Spent Fuel Transportation
The transportation of radioactive spent fuel can have a significant impact on bridge structures located on designated routes. Due to the critical nature of the cargo and because of the...

Transportation Access to Yucca Mountain: Critical Issues
Transportation planning for a repository at Yucca Mountain is complicated because of uncertainty about the modes and numbers of nuclear waste shipments and because of uncertainty about...

The CVSA Pilot Study of Highway Vehicle Inspection Procedures for the Transportation of Radioactive Materials
To further the goal of enhancing the safe and efficient transportation of radioactive materials, the US Department of Energy and the Commercial Vehicle Safety Alliance have entered into...

An Approach to Assessing the Impacts of Incident-Free Air and Highway Transportation of Radioactive Materials
Annual radiation doses and risks were calculated for shipments of radioactive materials both in passenger aircraft and on highways, under accident-free and incident-free conditions, i.e.,...

A First Look at Roadheader Construction and Estimating Techniques for Site Characterization at Yucca Mountain, Nevada
The Yucca Mountain site characterization program will be based on mechanical excavation techniques for the mined repository construction and development. Tunnel Boring Machines (TBM's),...

Development of a Pavement Design Expert System
The latest edition of the Guide for Design of Pavement Structures was published by the American Association of State Highway and Transportation Officials in 1986. This edition of the Guide...

Knowledge Representation for Bridge Design
An implementation of a frame-based knowledge representation language (KRL) for development of expert system applications in highway bridge design is presented. The frame-based KRL is used...

Expert System Applications for Bridge Engineering
Expert systems (ES) are computer programs that attempt to simulate the reasoning processes and knowledge of a human expert. The particular problem of bridge analysis/design is a prime...

Optimized Models for Predicting Structural Response in Highway Bridges
Optimization techniques are a viable option for modeling bridges that have been field tested. The error between the experimental strains and the analytical strains is minimized by adjusting...

Computerized Bridge Monitoring System
Research at the University of Connecticut has generated a full scale vibrational monitoring system for installation on a Connecticut bridge. The monitoring system consists of a field computer...

An Electronic Specification for the Earthquake Resistance Design of the Highway Bridges in Pennsylvania
An interactive C program for the seismic design of highway bridges in the state of Pennsylvania is described in this paper. The program was developed in C language on a personal computer....
