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,...

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...

Hydrodynamic Modeling on Vertically Mixed Bays
Extensive model-data comparisons of sea surface elevations and vertically-averaged velocities are performed on the Peconic Bays Estuary, New York, a system of interconnected bays where...

Some Considerations in Model and Field Data Selection for Circulation Studies of the James River Estuary
The major features of the circulation of the lower James River estuary are presented. The capabilities of numerical hydrodynamic models in reproducing these features are discussed, leading...

Sensitivity of Gulf of Maine Tide Model to Depth
A 2-D tide model of the Gulf of Maine failed to produce accuracies necessary for the de-tiding of Geosat satellite data. A subsequent sensitivity analysis indicated that the model was...

Pre- and Post-Processing Data Management Approach for Eutrophication Model of Peconic Bay, Long Island
A pragmatic data management approach for pre-processing and post-processing of large data sets from numerical models has been applied to a coupled hydrodynamic and water quality model...

2-D Particle Tracking Model for Estuary Mixing
This paper presents the development and analysis of a 2-D particle tracking or random walk model for the simulation of transport in vertically well-mixed estuaries. The model was tested...

Numerical Analysis of Flexible Culverts in Layered Soils
The deformation of flexible culverts is analysed using the finite element method as tool. Results of calculations for installation, traffic and time dependent loads are presented for culverts...

Florida Bridges Beat the Clock
Today, when budget overruns and delays on construction projects are the rule more than the exception, 11 precast segmental balanced cantilever bridges on two contracts were recently completed...

Bridges Under Surveillance
Although bridge monitoring is still in its infancy, research, pilot studies and field work are underway across the country. While today it's still a pie-in-the-sky goal, the...

Overhauling and Opening to Traffic of a Toll Tunnel in Marseilles (France)
The city of Marseilles called for bids for overhauling and opening to traffic an old unused railway tunnel, under the very center of the city. The tender scheme was a concession. The paper...

An Example of Privately Funded Project
The paper discusses the proposal of the Syndicat des Transports Parisiens, the local authority in charge of Public Transports in the Paris region, to ask private firms to implement without...

Raingage Network Resolution With Spatial Statistics
Spatial and temporal resolution of rainfall are studied using cross-correlation techniques. The cross-correlation coefficient is used in a semi-variogram type analysis to determine the...
