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...
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...
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...
Transport Planning on Auckland's North Shore
During 1987 and 1988, a major transportation study of the Auckland North Shore was undertaken by Takapuna City Council. Several major issues were addressed, including the size and shape...
Using GIS Techniques for Transportation Planning to Automate Compilation of Land Use Information
This paper describes a procedure used to compile land use or socioeconomic data for traffic analysis zones for input into a transportation planning model. The procedure uses a combination...
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...
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...
An Eulerian-Lagrangian Model for Sediment Transport in Estuaries
We describe a new depth-averaged numerical model for the simulation of the fate of sediments in estuaries. The model, denoted ELAsed, includes the following distinctive characteristics:...
A Field and Modeling Study of Fine Sediment Transport in Shallow Waters
As part of a major effort to understand and quantify the phosphorus dynamics in Lake Okeechobee, the transport of fine sediments has been studied by combining numerical modeling with an...
Siting the New Boston Harbor Outfall: Near-Field Analysis
In the near-field analysis for Boston's proposed Deer Island outfall to Massachusetts Bay, multiple initial dilution calculations were applied to estimate the frequency distribution...
Calibration of a Transport Model Using Halocarbons
A field study was conducted during April 1987 in which the concentrations of volatile halocarbon tracers, discharged from two existing outfalls, were measured throughout Boston Harbor...
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...
Contaminant Loading from Fox River to Lower Green Bay
The heavily industrialized lower reach of the Fox River, downstream of the DePere Dam, and lower Green Bay, Lake Michigan, are modeled. Hydrodynamics and contaminant transports to the...
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...
High Level Radioactive Waste Management 1990
The proceedings of the first annual Conference on High Level Radioactive Waste Management, held on April 8-12, 1990, Las Vegas, Nevada, provides information on the current technical issues...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
