A Data Base System for Hazardous Materials Transportation
This paper reports on a hazardous materials transportation study conducted in Arizona. Two types of surveys were conducted: hazardous waste shipments for 1983 and 1984 compiled from manifests;...

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...

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,...

Addressing the Risks of Computer Model Misuse
The proliferation of relatively inexpensive small computers, and accompanying transportation-oriented software, has brought many capabilities to transportation agencies previously unavailable...

Hydraulic Engineering
The papers in this book were presented at the ASCE National Conference on Hydraulic Engineering, August, 1987, Williamsburg, Va. The objective of this conference was to provide a forum...

Harbor Revived
In Racine, Wis., officials' plans to turn a defunct commercial harbor into a recreational boaters' paradise have signaled an economic turn-around for a depressed...

Operational Experiences With a Wells Turbine on a Wave Powered Navigation Study
The objective of the research programme was to design a 100W Wells turbine generator unit which could be matched to standard tail tube buoys. Optimization of the power conversion chain...

On the Performance of a Wave Power Converter
This paper presents the KN-principle for wave - power conversion. The principle and components of the wave power converter are described and some practical relations are presented in order...

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....

Solution to a Waterhammer Problem: A Case Study
Waterhammer is caused by a rapid change in the flow velocity of liquid in a pressurized pipeline. Therefore, the potential for waterhammer exists in almost every pressurized liquid piping...

Twisting in the Wind
Wind tunnel tests are being used increasingly to test the aerodynamic stability of bridges. Many designers think these tests should be used early in the conceptual design stage, rather...

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...

An Improved Method to Predict Annual Transit Fare Revenues from Mid-Year Results
Effective short-term financial management of transit systems requires the same three general actions necessary to manage all service oriented industries: 1)monitoring of short term (usually...
