Truck Operating Characteristics in Relation to Safety
For a two-year period large truck crashes on the interstate system in Washington State were investigated using a case-control method. For each large truck involved in a crash, three trucks...
Design Considerations for Trucks in Work Zones
In an Eastern state a 3. 8 mi (6. 2 km) work zone had 14 accidents during a project duration of 120 days. Eleven of the 14 accidents occurred at temporary crossovers where traffic was...
Accommodation of Large Trucks: Traffic Control Issues
The objective of this paper is to identify ways that large trucks can be accommodated safely and efficiently through traffic control. Traffic control is herein defined as encompassing...
Accommodating Larger Trucks at At-Grade Intersections
When a particular intersection serves a high volume of large truck traffic, design considerations should reflect the presence of those larger vehicles. This paper discusses three intersection...
A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...
Probabilistic Design of Flexible Pavements
Numerous random phenomena enter into the process of deterioration of pavements under the effect of traffic. It is felt that improvement in current design methods could be obtained by adopting...
A Probabilistic 3-D Short-Term Slope Stability Model
A probabilistic model to analyze the three-dimensional stability of earth slopes under short-term conditions is presented. An actual failure case is studied to show the implementation...
STOCAL-II-An Instructional Software for Random Vibrations
STOCAL-II (Computer Assisted Learning of STOchastic methods) is an instructional software for teaching random vibrations and applied stochastic processes. It is based on and is an extension...
Bridge Reliability?Evaluation vs. Design
Probabilistic methods of structural safety are being widely accepted as a basis for rationally considering uncertainties and developing reliability based design specifications for various...
A Stochastic Seismological Model in Earthquake Engineering
Recent studies of source mechanisms and wave propagation models enable one to generate strong motions based on deterministic source and source-to-site characteristics. The normal mode...
Rehabilitation of Highway Bridges: Design and Operational Considerations
The design of a rehabilitation of a bridge which must maintain some lanes of traffic requires special consideration of construction procedures and traffic control, which are discussed...
An Expert System for Reliability Engineering
The goal in this project is to create an expert system to do failure mode investigations from 'first principles,' or the basic understanding of the way components...
Experiences with Applications of Importance Sampling in Structural Reliability Computations
This paper presents some experiences and observations relating to the use of importance sampling in structural systems reliability computations. These are presented with three examples,...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
Approximate Reasoning in Engineering Decision Analysis
In this paper, the concept and methods of approximate reasoning are reviewed and discussed. The methodology of combining precise results of exact analysis, approximate solutions of exact...
Nonstationary Random Vibration with REDUCE
Computerized symbolic algebra, in conjunction with the code REDUCE, is utilized in dealing with nonstationary random vibration of single-degree-of-freedom systems. Application of REDUCE...
An Intelligent Design Support System for Computer-Aided Site Development
This research proposes an intelligent design support system (DSS) integrated with a CAD environment for building site planning and development. The DSS is used for providing a good initial...
A Rule Based Expert System for Reservoir Operation
Recent advances in artificial intelligence and expert systems development have attracted many scientists and researchers. Reservoir operation is an ideal field for such research due to...
Managing Microcomputer Applications
The authors have recently completed a study of microcomputer usage in Corps of Engineers planning activities. The study developed a training document for Corps managers, entitled 'Managing...
Living with a Macintosh in an IBM World
