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...
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),...
Conversion of the MIDAS Accident Analysis Model
The MIDAS (Michigan Dimensional Accident Surveillance) System has been developed to provide accident analysis capability. A microcomputer version of MIDAS is being developed to make the...
Teacher Friendly Transportation Programs
This contribution describes a set of computer programs that has mainly been developed to demonstrate operating and possibilities of mainframe programs during lectures. The program set...
Expert Systems for Traffic Signal Control
The level of service achieved by a pretimed signal timing control strategy implemented at an isolated intersection incurring saturated and over-saturated demand varies with actual traffic...
Optimal Strategies for Phase Control of Wave Energy Devices
Phase control has previously been proposed for increasing energy output from wave power devices, and latching strategies have been tested for point absorbers and for pneumatic devices....
Evaluation of Sediment Transport and Friction Factor Equations Using MOBED
Three sediment transport rate equations and the same number of friction factor equations for mobile boundary channel flows were evaluated using a mobile boundary flow model called MOBED....
The Strategic Use of Information Systems in Urban Transportation
Computer information systems have been used by many private firms to improve the quality and change the character of the products and services they provide. Such uses of computers are...
Construction Guide Liners
Geomembrane liners for waste construction require meticulous construction, monitoring and weather watching. With much concern over the longevity of geosynthetics, many overlook the extreme...
Supervisory Control System Design
This paper presents supervisory control concepts, elements of a typical system, testing activities, project management, and the procurement process. Modes of control systems are discussed...
Maximum-Slew-Rate Nonlinear Control for Improved Transient Response in Hydrogenerators
This paper considers a linearized model for fixed blade turbines. This paper demonstrates that constant gate speed bang-bang control holds potential advantages over current control techniques....
Economical Computer Controls for Low Head Hydro
Small power systems based on renewable energy sources such as low head water falls, wind, solar and ocean tides all suffer from stochastic changes in input power. Economically viable,...
Advances in Controls to Govern Mini and Micro Hydropower Systems
Conventional controls available for small hydropower systems are surveyed. Electronic load controls for micro hydropower systems are described. Recent developments in the literature are...
Design and Application of an Open-Loop Control System for Run of River Sites
This paper compares an open loop control system for variable geometry turbines to a closed loop system for fixed geometry turbines. The control systems were designed to operate three submersible...
FEM-Flow Analysis in Hydraulic Turbomachinery Runners
Finite element calculations of the flow through distributor and runner of hydraulic turbomachines are presented. The method is quasi-3D and inviscid, but the deviations from a potential...
Uncertainty Analysis of Field Turbine Performance Measurements
This paper presents comprehensive uncertainty analyses of two different flow measurement methods for field tests on turbines. The 'water to wire' efficiency was...
A Review of the Cross-Flow Turbine
The historical development of the cross-flow turbine is briefly presented together with a summary of the well-documented one-dimensional theory. Two-dimensional aspects of runner design...
Risk Sharing in Project Development
This paper reviews some of the areas in which attention to detail can make the contractual relationship more positive and lead to a better project. Subjects covered include: selecting...
Laser-2-Focus Flow Measurements in the Runner of a Bulb Turbine and Comparison with Calculation
Flow measurements are presented, which were carried out near and inside the 4-blade runner of an axial model bulb turbine of double adjustable type. These measurements were performed by...
