Water Quality Management Through Project Operation
Harry S. Truman Dam, a multipurpose reservoir project, is located on the Osage River in the headwaters of the Lake of the Ozarks. Construction of this project created the potential to...

Reservoir Water Quality Assessment Using in Situ Microcosms
Although there are a number of techniques for determining the limiting nutrient, as will be demonstrated, in-reservoir microcosms permit in situ experiments to be conducted under relatively...

The Santa Ana River Flood Forecasting System
A real-time flood forecasting and reservoir operations simulation system has been developed for the Santa Ana River Basin, located in southern California. The system consists of generalized...

A Riverflow-Water Quality Control Model
In order to implement how regulated riverflow (control variable) impacts the salinity (output variable) under a tidal dynamic environment, a multiple input control system is developed....

Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...

Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...

Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...

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....

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...
