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
A new computerized microscopic traffic simulation model ROADTEST is described. The model a general purpose one, permits simulation of any vehicles including trains and fixed route transit...
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...
County-Level Planning Model in Atlanta Region
Gwinnett County is working with the Atlanta Regional Commission (ARC) and Barton-Ashman Associates to download the ARC trip tables for use in a microcomputer transportation planning model...
Traffic and Transport Data Management by Micro-Computer
Dealing with the multiple needs of an adequate traffic and urban transport information system is becoming a manageable task with the software and hardware presently available in micro-computing....
Simulation of Intersections During Reconstruction
In order to make computer simulation of intersections more appealing and easier to use, and interactive, menu-driven micro-computer program, called INTERCON (Michalopoulos and Plum, 1986),...
The Wet Look
The collapse of the Schoharie Creek bridge drew attention to underwater inspection. Underwater inspection of bridges gives engineers a better understanding of the condition of the bridges....
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....
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...
Surveying for Scour
The public works engineer never knows exactly how many bridge piers and abutments are undermined by erosion due to scour. Massachusetts Department of Public Works needed a rapid method...
Beyond Digital Mapping
Northern Ireland, small and compact, geographically well defined with a relatively simple administrative structure, is able to establish a comprehensive Geographic Information System (GIS)...
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...
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...
Checking Turbine Performance by Index Testing
This paper discusses an index testing procedure used by TVA for measuring performance levels of its hydroelectric units. It also describes a current program for retesting generating units...
