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),...

Use of Transport Models in Airport Access Analysis
This paper describes transportation models built by Wilbur Smith and Associates (WSA) as part of a study of Newark International Airport (NIA), conducted for the Port Authority of New...

The Use of Microcomputers to Perform Airport Emission Inventories
The authors found the use of LOTUS 1-2-3, a microcomputer spreadsheet package that permitted easy calculation of emissions and easy revision of data for studying options in aircraft types,...

A Simulation/Animation of an Inland Railway Container Terminal
The Container Terminal Model (CTM) comprises a batch computer simulation model and interactive graphics animation package. The model has been developed to aid engineers and transportation...

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...

Expert System for Transportation Corridors
Semantic nets and frame representations are used by an expert system under development to assist in the selection of projects and control strategies in transportation corridors. The project...

Expert Systems Approach for Analysis of High Hazard Locations
This paper focuses on the detailed analysis of specific highway locations that have been identified as hazardous in the framework of a State Highway Safety Improvement Program (HSIP)....

CAD Generation of Accident Diagrams for Local Agencies
This paper reviews one such issue, safety, focusing on the development of a user-interface with a microcomputer CAD system. With this interface, the system is used to generate collision...

Use of CAD for Traffic Sign Design Purposes
At present, AutoCAD is the most popular CAD system for micromputers. It is relatively inexpensive and is very flexible, comprehensive, and easy to use. A preliminary review of AutoCAD...

Photogrammetric Analysis Using a Personal Computer
In many cases, photographs of the accident scene taken soon after the event contain visible evidence of road marks and/or debris. By the time the case reaches the accident investigator/reconstructionist,...

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....

Public and Private Sector Strategies to Deal with Urban and Suburban Congestion
Urban transportation congestion both in the case of our cities and in many of our suburbs, has exceeded tolerable limits in many parts of the nation. Public agencies operate under very...

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...

Microcomputer Applications in Transportation II
This book contains over 80 papers associated with the North American Conference on Microcomputers in Transportation held in Boston, Mass., from June 29-July 1, 1987. The papers address...

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...
