A Matching Algorithm That Eliminates the Need for Radio Signposts in Automatic Passenger Counters on Buses
Volumes of raw data collected using the Automatic Data Aquisition system are useless until they can be processed and transformed into meaningful reports and plots. This is done using a...

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...

Computerized Transportation/Financial Planning Processes
The Computerized Transportation/Financial Planning Process (CTFP) comprises a battery of programs that collectively form a valuable growth management tool. CTFP incorporates four spreadsheet...

Incorporating Risk Analysis Into Spreadsheet Forecasts
The risk analysis technique presented overcomes the difficulties of sensitivity analysis by entering key input variables as probability distributions, rather than as discreet values. Using...

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...

Advances in Trip Matrix Estimation
The derivation of Origin-Destination (O-D) trip matrices is a vital component of much transportation planning. Obtaining accurate O-D data often poses a challenge on account of the large...

Computer Analysis of Origin-Destination Survey Data in the State Route 55 Travel Corridor, Before and After the Opening of Carpool Lanes
The State Route (SR) 55 carpool lanes in Orange County were opened for high occupancy vehicles (HOV) usage in November, 1985. Since SR 55 was the first travel corridor in Orange County...

Traffic Congestion Data Collection and Analysis System
The system was developed to allow traffic engineers to analyze the magnitude, duration and location of traffic congestion on highways and city streets. It is used to prioritize traffic...

Maximizing Your Use of Interactive Graphics in Transportation Simulation Modeling
The paper discusses the capabilities, through the aid of computer graphics,now that exist to take analysis and reporting of traffic simulation model studies several steps further than...

Dynamic Assignment Modelling with Trips
This paper describes additional ways in which TRIPS models time-varying, or 'dynamic' effects. These include area-wide effects as vehicles move through the network,...

A Survey of Three-Dimensional Numerical Estuarine Models
This paper surveys the existing 3-D estuarine hydrodynamic and solute transport models by a review of the commonly used assumptions and approximations, and by an examination of the methods...

Curvilinear Long Wave Hydrodynamic (CLHYD) for Tidal Circulation and Storm Surge Propagation
The objective of this paper is to demonstrate the ability of a two-dimensional long wave hydrodynamic model to simulate long wave processes in curvilinear coordinates. The series of tests...

Application of a Boundary Fitted Coordinate Hydrodynamic Model
A three-dimensional, boundary-fitted hydrodynamic model was applied in a two-dimensional, vertically-averaged mode to predict the tidal circulation in Mt. Hope Bay, a small estuary located...

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...

Modeling and Data Uses in Hydraulic Transport Investigations, New Bedford Estuary, Mass.
Field measurements, laboratory tests, and models were used together to make transport predictions for the sediments and dissolved materials which would be released by proposed dredging...

Dispersion Analysis of the Dartmouth, MA Municipal Sewage Outfall Off Salters Point
The water quality impacts of the existing and proposed upgraded Dartmouth, Massachusetts Wastewater Treatment Plant on the Salters Point region of Buzzards Bay were examined through the...

Long-Term Fate of PCB Contamination in the New Bedford Harbor, Massachusetts, System
The transport and fate of polychlorinated biphenyls (PCBs) at the New Bedford Harbor Superfund site is modeled using a three-dimensional hydrodynamics and sediment-contaminant transport...

Circulation and Transport Modeling in New Bedford Harbor
Three-dimensional hydrodynamics and mass transport were simulated in the New Bedford Harbor, Massachusetts, area in support of a combined sewers/sewage outfall facilities planning project...

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...
