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...
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...
Eutrophication and Nutrient Enrichment in Peconic Bay: Numerical Model of Historical Conditions of the Mid-1970s
In response to water quality and resource management issues triggered by the brown tide bloom of 1985-88 in the embayments of the Peconic estuary of Long Island, New York, a coupled hydrodynamic...
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...
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...
CTA's Experience in Fostering Station Redevelopment Through Public/Private Partnerships
