Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...

Evaluating Nonlinear Soil Behavior Using the Resonant Column
An analysis is presented that attempts to match a mathematical model to the nonlinear behavior obtained from the resonant column test. This model consists of an oscillator with a restoring...

Centrifuge Model Testing with Dynamic and Cyclic Loads
This paper examines the use of small-scale tests on centrifuges to study a wide range of problems in soil dynamics - including machine foundations, structures and explosion effects. The...

Energy Forecasting Techniques: An Overview
This paper provides an overview of the primary forecasting techniques employed by electric and natural gas utilities to predict energy consumption and demand. Although the techniques discussed...

Development of Flood Peak Regression Equatins for Small Watersheds in Southwest Florida
Hydrologic investigations were performed on the Belle Meade-Royal Palm Hammock area in Collier County, Florida. The study area, encompassing approximately 79 square miles (205 km**2),...

Streamflow Losses in the Santa Cruz River, Arizona
The discharge and volume of flow in a peak decrease as the peak moves through an 89-mile (143 km) reach of the Santa Cruz River. An average of three peaks per year flow the length of the...

Transportation Systems Forecasting Using Microcomputer Models
This paper describes the evaluation of six transportation forecasting programs which operate on microcomputers. The evaluation is undertaken from the perspective of a metropolitan planning...

Managing Federal Aid Using Microcomputers
Wisconsin's federal aid for highway improvement is about 225,000,000 annually. The obligation authority (the ability to spend the federal aid) is limited to an estimated 162,000,000...

A Model for Evacuation of Transportation Networks
MASSVAC is a computer simulation model developed for the analysis and evaluation of evacuation plans for urban areas threatened by natural disasters. In addition to area demographic characteristics,...

A Freeway Simulation Program for Microcomputers
An interactive, menu driven macroscopic freeway simulation program with graphic capabilities is presented in this paper. In addition to the employment of personal computers the program...

Applications of Computer Graphics in Traffic Control
Computer models to develop improved designs and traffic management schemes are used more effectively with graphical displays of their results. This paper describes the TRANSYT DISPLAY...

ITDS: A Data Base Driven Interface to Traffic Models Using a Microcomputer
The author presents a system which solves many traffic control problems. The Integrated Traffic Data System (ITDS) is a set of microcomputer programs which provides an easy-to-use interface...

A Microcomputer-Based Safety Management System
An agency's effectiveness in undertaking its highway safety responsibilities is most critically dependent upon the information available and the means provided to access and...

DEL: A Fare Revenue Forecasting Model
As there could be several pricing alternatives producing the same amount of overall fare revenue, the solution search usually requires judgement in light of the predefined set of objectives...

Evaluation of the Driver/Extraboard Cost Model
This paper presents a general evaluation of the Driver Extraboard Cost Model. The evaluation is based on a series of validation tests performed using data from the Tri-County Metropolitan...

Graphics-Based Transportation Modelling with DIME/GADS/NEDS
Graphics helps analysts, policy-makers and the public understand the inter-relationships of land use patterns and transportation systems. A suite of graphics-based programs provide a decision-support...

Regional Planning Models Used in Subarea Windows
The typical regional travel-forecasting model has historically been confined to use on a mainframe computer. In an effort to reduce costs and allow computer hardware options, a three-tiered...

Microcomputer Site Models for Project Analysis
In 1984, the Genesee Transportation Council, the MPO for the Rochester New York area, undertook a study with the City of Rochester Bureau Of Planning and Zoning to investigate how microcomputers...

Traffic Planning Using Interactive Color Graphics
This paper describes the MULATM microcomputer traffic planning model, as an example of the possible uses for microcomputers in transportation planning. These uses include interactive input/output,...

Applying the Bus Garage Space Requirements Model
The Bus Garage Space Requirements Model (BBARN) is a computer-based model developed by the author to generate a detailed space program for an office/bus maintenance facility. BBARN provides...
