On-Off Terminal Ship-to-Rail Transfer
The intermodal situation of U.S. ports is still evolving, and port planners will be facing difficult decisions regarding IM Configurations. This article was intended to assist 'perplexed'...
Application of Traffic Engineering Concepts to Pleasure Boat Traffic
The Los Angeles County Department of Beaches and Harbors initiated a study to investigate the feasibility of adding slips along the main channel in Marina del Rey in response to the surplus...
Global Warming and Possible Effects on the Central and Southern Florida Project
The possible impacts of global warming on the operation and management of the Central and Southern Florida Project are examined. The potential impacts include sea level rise, tropical...
Probability and Climatology of Droughts in the Western United States
The incidence of drought in the western United States is caused primarily by large-scale anomalies in the circulation of atmospheric, midlatitudinal, transport and the occurrence of the...
A Multi-objective Criteria Analysis for Alternative Route Planning
A multi-objective criteria analysis was used to identify a proposed rail spur route with the optimal combination of low environmental impact, favorable engineering characteristics and...
Use of the Break-Off Method for the Evaluation of High Performance Concrete
The Break-Off test is one of the recent developments for testing in-place concrete strength. This research was undertaken to investigate the reliability of the Break-Off test as a measure...
High Strength, Low Permeability Garage Rehab Concrete
Physical and engineering properties of high strength structural lightweight concrete used to replace deteriorated concrete in garage structure rehabilitation programs are reported. Structurally...
Transportation Lifeline Losses in Large Eastern Earthquakes
In December 1991 Applied Technology Council (ATC) and its subcontractor, EQE Inc., completed a 2-year Federal Emergency Management Agency-sponsored study to assess the seismic vulnerability...
Rehabbing the Rails
In 1984, during a routine bridge inspection, a worker detected deterioration under the south abutment of a bridge that carried the main line of Philadelphia's commuter railroad....
HOV Lessons
As traffic congestion worsens, transportation planners are struggling to squeeze out every last bit of available roadway capacity. High-occupancy vehicle lanes are one solution, but aren't...
The Great Chicago Flood of 1992
In April of 1992, a breach in a freight tunnel caused the river that flows through Chicago to pour into city building basements, causing the city to shut down. Critical utility systems...
Special Considerations for Railroads
In comparison with highway bridges, railroad bridges are generally characterized by a larger ratio between traffic and dead load, larger braking forces, smaller relative width of the bridge...
High-Performance Concrete in All-Weather Deck Pours
A high-performance concrete mix enhanced with a combination of microsilica, superplasticizer, and high dosages of an corrosion-inhibiting, accelerating admixture (calcium nitrite); proved...
Analysis of Waterbody Surface Heat Exchange
The Edinger-Duttweiler-Geyer (EDG) approach for estimating heat exchange at a water surface was examined and its applicability to ice-covered waterbodies determined. The EDG linearized...
Snow Transport as a Function of Wind Speed and Height
When limitations are placed on mass flux in the saltation layer, a regression equation relating mass flux to wind speed and height above surface, developed by Mellor and Fellers (1986),...
White Steel for Osaka Bay
Wind, earthquake and aesthetics were the design determinations for Japan's Higashi-Kobe Bridge. The designers also had to consider the man-made bay infill site and a directive...
Tomorrow's Toll Road
Techniques using automatic vehicle identification (AVI) currently provide the most efficient form of electronic toll collection. Several systems have been installed in the U.S. in the...
Development of Preliminary Nevada Transportation Accident Characteristics
The U.S. Department of Energy (DOE), Yucca Mountain Site Characterization Project Office (YMSCPO) has been given the responsibility for characterization of the potential repository site...
Development of Rail Access to the Proposed Repository Site at Yucca Mountain
In accordance with the Nuclear Waste Policy Amendments Act of 1987, Yucca Mountain was designated as the initial site to be investigated as a potential repository for the disposal of high-level...
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...
