A User-Friendly Capital Programming Tool for Highway Maintenance Districts
The Roads and Waterways Administration of Finland is developing a microcomputer system, called the Project Analysis System (PAS), to help district engineers in their annual preparation...
Estimating Toll Diversion for Beltways
The proposed E-470 beltway is a 48-mile circumferential highway which will connect major public and private developments east of the Denver metropolitan area as well as the new Denver...
Transit Scheduling Using Computer Graphics
Graphical scheduling has been very popular throughout the world, but until recently, has not been available for a computerized scheduling system. Computerized graphical scheduling systems...
GRREATdB - GRaphic Roadway Editor and Analysis Tool
This paper describes the development and use of a tool to link textual databases to road network-based interactive graphics. Advantages of the system are discussed. The GRREATdB program...
Processing Automatically Collected Patronage Data
Since the late 1970's, the San Francisco Bay Area Rapid Transit District (BART) has had the capability to automatically collect trip origin and destination data from its faregates. This...
Pavement Inventory and Evaluation Systems Using Microcomputer Data Base Managers
The two most commonly used relational DBMS (Data Base Management System) softwares are Ashton-Tate's 'dBASE III Plus', and Microrim's 'R:Base 5000'. This paper illustrates the use of these...
Combining the Census Tiger Files and Geographic Information System Technology for More Effective Transportation Planning
The Bureau of the Census, in cooperation with the U.S. Geological Survey, has created a topological data base containing every street and block face in the United States for use in the...
Evolution of a Three-Dimensional Curvilinear-Grid Hydrodynamic Model for Estuaries, Lakes and Coastal Waters: CH3D
Traditional finite-difference models of estuarine, coastal and lake hydrodynamics and transport use rectangular Cartesian grids in the horizontal directions. In order to accurately represent...
Application of Particle Tracking Model for Ocean Outfall Siting in New Bedford, Massachusetts
PACE, a particle tracking model, was used to assist siting studies for an ocean outfall to be built in conjunction with the City of New Bedford's proposed new secondary wastewater...
Modeling a Wind-Mixing and Fall Turnover Event on Chesapeake Bay
A three-dimensional (3D) numerical hydrodynamic model of Chesapeake Bay has been developed. Results from application of the model to one of the three data sets employed in the verification...
On Numerical Strategies of Estuarine and Coastal Modeling
Numerous numerical models of circulation and transport for estuarine and coastal waters have been developed. A variety of numerical techniques are used by these numerical models. This...
Estuarine, Shelf, and Ocean Hydrodynamic Modelling Approaches
Estuarine, shelf, and ocean hydrodynamic modelling approaches are presented in order to explore the development of a coordinated set of models to describe the complex interactions between...
Boundary Fitted Estuarine Water Quality Model
A two-dimensional, vertically-averaged boundary fitted coordinate pollutant transport model was developed for application to estuarine and coastal sea regions. The governing convective-diffusion...
Three-Dimensional Modeling of Pollutant Transport
A numerical model for pollutant transport in coastal waters has been developed in x-y-z-t space. The simplicity of a fixed Eulerian mesh and a computationally efficient Lagrangian approach...
Model Comparisons of Oyster Recruitment in Delaware Bay
A second order particle trajectory model using surface currents from a three-dimensional model of Delaware Bay was run for a period equivalent to the larval stage of the oyster C. virginica...
Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...
Education and Continuing Development for the Civil Engineer
Setting the Agenda for the 90's and Beyond
The 1990 Forum Proceedings is a collection of papers that were written to provide a basis for deliberation and conclusions at the ASCE 1990 National Forum on Education and Continuing Development...
Sons of Martha: Civil Engineering Readings in Modern Literature
These three stories excerpted from the new book Sons of Martha, compiled by Augustine J. Fredrich and published by ASCE as the first book in a new venture by the Publications Division, introduce the engineer...
The Great American Pyramid
For more than 50 years officials of Memphis, Tenn. have wanted to establish a link to their Egyptian namesake--and they will, through a pyramid. As opposed to its Egyptian forerunners,...
Implementing the E-470 Beltway
The paper addresses various elements of implementing the 50 mile eastern half of the beltway around the Denver metro area. This paper addresses many unique characteristics associated with...
