System Reliability Using Expert Opinion
The objective of the study on which this paper is based was to determine the safe performance of several different interior gas piping systems. This paper describes the piping systems...
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...
Reliability Based Optimal Structural and Mechanical Design
A reliability based optimal design strategy has been developed. Nonlinear limit state functions and nonnormal random variables can be accommodated. For structural systems analysis, a failure...
A Kinematic Approach to Simulation-Based System Reliability Evaluation
System reliability of complex structural engineering systems is often estimated by simulation-based procedures, with failure analysis based on a static (limit state) formulation or a kinematic...
Engineering Reliability: The Organizational Link
Organizational factors may significantly affect systems' reliability, but they are not typically included in modeling. This paper discusses how the stochastic models of system...
Highway Injuries: Our Major Health Problem
Injuries are the leading cause of death in the United States from early childhood until about age 45. Motor vehicles kill more Americans age 1 to 34 than any other source of injury or...
Embankment-Dam Breach Parameters
The study used data from 43 embankment-dam failures to develop equations that predict breach formation model parameters. These data include the failure mode, embankment characteristics,...
Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
Evaluation and Testing of Travel Demand Software
Transportation planners are frequently confronted with issues and concerns related to varying levels of analysis detail. Although microcomputer packages exist to analyze regional, corridor...
Transportation Network Building Using a CAD Interface
This paper illustrates how Barton-Aschman Associates, Inc, has made use of AutoCAD(TRADEMARK) on the microcomputer to digitize an existing highway network and to create a new network from...
Trip Table Estimation from Observed Traffic Volumes
This estimation technique identifies the most likely trip table to produce a specified set of traffic counts when assigned to a representative highway network. The resultant table is derived...
Census Data in Travel Demand Model Development
The New Jersey Department of Transportation purchased the Statewide 1980 Census Urban Transportation Planning Package (UTPP) and began offering this information to other Government Agencies...
Downloading Baltimore Regional Databases
The Regional Planning Council (RPC) now is exploring through trial-and-error, the most effective, efficient means of performing travel demand forecasts cooperatively with its 'clients....
A Travel Demand Modeling System for Istanbul
This paper describes the development and application of a microcomputer-based travel demand modeling system as part of an 18-month planning and feasibility study for the Istanbul Metro...
Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...
Intrinsic Models for Interactive Structural Design
This paper introduces a 'generic' model for interactive design of constructed facilities. The proposed methodology takes real world conditions, in terms of load...
Pattern Recognition Techniques for Distinguishing Structural Failure Modes from High Pressure Loading Records
Pattern recognition techniques have been successfully employed in a wide variety of fields, such as geophysical exploration, medical diagnosis, radar tracking, and earthquake structural...
Street Fares
An argument is made for imposing user fees to amass funds for repair and maintenance of local roads and streets. These infrastructure services have to compete for local general property...
How to Use a Transit Consumer Information System
This paper reports the results of an effort to implement a consumer information system in a small urban area. The system was designed to periodically report the travel patterns and viewpoints...
