Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...
Evaluating Mitigative Options for Critical Facilities in Hurricane Prone Regions
This paper describes, and demonstrates the use of, a methodology to evaluate the safety of occupants in structures subjected to hurricane forces. Occupant safety is expressed in terms...
Reliability-oriented Design of Fatigue Experiments
It is well known in the reliability analysis for structural components subjected to cyclic random load that apart from the usually model parameters uncertainties are most important and...
Reliability Revision for Structures in Service
Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available....
Dynamic Fracture Toughness of Rail Steels
As new premium alloy rail steels exhibit increased wear resistance and as track lubrication is used, the failure mode for rails is shifting from wear to fatigue. Elastodynamic finite element...
Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...
Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...
Top Projects of 1987
Five notable entries in the 1987 Outstanding Civil Engineering Achievement competition are summarized. The Keehi Interchange of the H-1 Freeway in Honolulu is only 1.9 miles long, but...
Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...
Comparison of TRC 212 and SR 209 LOS Calculations
With the release in 1985 of Transportation Research Board (TRB) Special Report (SR) 209, numerous traffic engineering agencies began the transition to new methods of calculating capacity...
Integrated Information System for Traffic Control Device Management
Traffic engineers and planners have the day-to-day responsibility to maintain the safety and operational efficiency of streets and highways in their jurisdictions. Managing traffic control...
Intelligent User Interface for Network Signal Optimization Programs
This paper presents the design philosophy and program intelligence used in EZ-TRANSYT and EZ-SIGOP, powerful multi-window input data managers for TRANSYT-7F and SIGOP-III, respectively....
SIDRA?An Australian Program for Signalised Intersection Analysis
As more complicated signal phasing systems have been implemented in practice, the analysis methods have moved from a phase-control philosophy applied to approach roads to a group-control...
Estimating Future Traffic Volumes at the Intersection Level
This paper uses the experience gained on a number of regional and sub-area studies in the northeast to illustrate how measured and forecast traffic information can be combined to predict...
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...
GTRAF: The Netsim Graphics System
This paper describes the development of an interactive computer graphics (ICG) system, named GTRAF, which will provide users with a new and highly efficient methodology for analyzing results...
A Decision Support System for Freeway Corridor Analysis
When the scope of a particular corridor study dictates the review and analysis of a relatively large number of road segments along major transportation corridors, the integration of roadway...
Traffic Engineering Data Collection Using Custom Equipment and Microcomputer System Equipment and Procedures
This paper presents experience with various traffic engineering data collection equipment and devices. It presents criteria for the development of a general purpose data collection system....
ROADTEST?A Microscopic Traffic and Transit Simulator
