The Development of a Plan of Study to Evaluate the Physical and Biological Effects of Increased Navigation Traffic on the Mississippi River
An integrity team prepared a Plan of study (POS) that represents the first comprehensive effort on the Upper Mississippi River (UMR), to identify and quantify impacts associated with commercial...
Microcomputer Applications in Transportation III
This proceedings consists of papers presented at the International Conference on Microcomputers in Transportation which was held on June 21-23, 1989 in San Francisco, California. They...
The Stacked Drift Tunnel
The Mount Baker Ridge Tunnel is the first of its kind and the last: a forward thrust of technology and a look back to the flow of federal highway funds, which paid 90% of its cost. The...
Wood Variability Effects in Structural Assessment
Engineers evaluating the load carrying capacities of in-service wood structures commonly determine the strength and stiffness properties of structural wood members by various assessment...
Time-Dependent Behavior of FRP Lintels
This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or...
Flexural Strength of Externally Reinforced Concrete Beams
Results from tests of one rectangular and one T-beam are reported. The beams were strengthened by epoxy-bonding a 1/4 in. (6 mm) thick Glass Fiber Reinforced Plastic plate along the tension...
Let the Buyer Beware
As recently as the 1970s, state highway agencies blindly purchased land for projects without much concern for hazardous waste. But that changed in 1980 with Superfund legislation, specifically...
Untangling A Can of Worms
Increasing traffic volumes combined with rush-hour delays and commuter complaints have spurred New York State DOT to improve the capacity of a major interchange near Rochester. The interchange,...
Facelift For an Interchange
The authors describe a $250 million reconstruction project on a three-level interchange linking I-84 and I-91 in Hartford, Conn., which is the largest rehabilitation project in the state's...
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,...
Commuter Control
Traffic management systems are a relatively new way to expand the capacity of existing highways and to utilize new ones realistically. Several major systems have been in place and new...
Reconstruction Under Traffic: A Study of Some Effects of the Dan Ryan Project on Motor Carrier Operations in Northeast Illinois
The paper discusses preparations by the Chicago Area Transportation Study for a study of the operational responses of truckers to whatever effects upon the regional highway system are...
The Truck Commodity Survey in the New York-New Jersey Metropolitan Area
The Truck Commodity Survey was designed to gather information on the characteristics of truck traffic at toll barriers with minimal disruption to traffic flows. It was developed by the...
Truck Involvement in Fatal Urban Road Accidents in Australia
Trucks are over-represented (relative to vehicle numbers and vehicle-kilometers of travel) in fatal accidents. Those most at risk are occupants of other vehicles and pedestrians. Articulated...
Double Angle Bracing Members
It has been pointed out that when a single line of bracing is used, the member is usually made from structural tubing. It has been suggested that when the loads are not too great, consideration...
Automated Load Capacity Determination of Cold-Formed Steel Compression Members
This paper presents an automated approach for the evaluation of the axial load capacity of nine cold-formed steel sections according to the latest AISI-1986 Cold-Formed Steel Specification....
Fast Track Paving May Offer Applications to Structures
'Fast Track' is a technique that permits portland cement concrete pavements to be opened to traffic in a day or less after they are poured. The method has been...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...
Effect of Temperature on the Load-Carrying Capacity of Fiber Glass Reinforced Plastic Beams
This paper describes an experimental investigation into the behavior of two T shaped beams made of fiber glass reinforcement and polyester or vinylester binders. Tests were performed at...
