Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...
Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...
Analysis of Drought Indicators
The Pennsylvania Department of Environmental Resources currently monitors five parameters in its regional water supply management program. These are: (1) accumulated precipitation deficit;...
Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...
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....
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,...
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...
Fishing the Four-Lane
Recent changes in one Montana canyon have shown that even highways and freshwater fish can happily coexist with the proper planning. Twenty years ago, the Montana Department of Highways...
Applications of an Integrated Traffic Analysis Package
This paper presents an integrated traffic analysis package called AAP (the Arterial Analysis Package). AAP, which was developed by the Federal Highway Administration (FHWA), contains three...
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...
Considerations in Applying the 1985 HCM Procedures
The paper examines the impact of critical assumptions in the 1985 Highway Capacity Manual (HCM) procedures on the resulting measures of effectiveness -- volume/capacity ratio, delay, and...
Modeling Permissive Movements in TRANSYT-7F
Traffic Network Study Tool (TRANSYT-7F) is one of the most widely used traffic flow analysis and traffic signal timing optimization models in the United States and elsewhere. Through 'Release...
Modeling Dual-Ring Actuated Signals with TRANSYT-7F
Current and potential future methods of using the TRANSYT-7F computer program to model dual-ring actuated traffic signals are discussed. First the problems encountered in using this fixed-time...
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...
An Adaptive Control Strategy for Signalized Intersections
This paper presents a microprocessor-based computational strategy for real-time demand-responsive traffic signal control. The strategy, termed OPAC (Optimization Policy for Adaptive 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....
