The Use of Interior Guide Tube in Cross Flow Turbines
The Cross Flow Turbine has the distinct advantage of lower initial and operating costs over other small scale turbines, but it is believed to lack somewhat in efficiency. In this study...
Processes of Meander Bend Migration
The flow pattern in a meander bend is described in terms of the primary flow, secondary flow, and cross-stream flow. Secondary flow which is normal to the primary flow contributes to lateral...
Highway Injuries: Our Major Health Problem
Injuries are the leading cause of death in the United States from early childhood until about age 45. Motor vehicles kill more Americans age 1 to 34 than any other source of injury or...
Activity Center Development Impact Analysis
A flexible microcomputer spreadsheet analysis method is described for analyzing area-wide and localized impacts of new development in urban or suburban activity centers. The analysis approach...
Evaluation and Testing of Travel Demand Software
Transportation planners are frequently confronted with issues and concerns related to varying levels of analysis detail. Although microcomputer packages exist to analyze regional, corridor...
Transportation Network Building Using a CAD Interface
This paper illustrates how Barton-Aschman Associates, Inc, has made use of AutoCAD(TRADEMARK) on the microcomputer to digitize an existing highway network and to create a new network from...
Trip Table Estimation from Observed Traffic Volumes
This estimation technique identifies the most likely trip table to produce a specified set of traffic counts when assigned to a representative highway network. The resultant table is derived...
Census Data in Travel Demand Model Development
The New Jersey Department of Transportation purchased the Statewide 1980 Census Urban Transportation Planning Package (UTPP) and began offering this information to other Government Agencies...
Downloading Baltimore Regional Databases
The Regional Planning Council (RPC) now is exploring through trial-and-error, the most effective, efficient means of performing travel demand forecasts cooperatively with its 'clients....
A Travel Demand Modeling System for Istanbul
This paper describes the development and application of a microcomputer-based travel demand modeling system as part of an 18-month planning and feasibility study for the Istanbul Metro...
Distributed Graphical Transit Scheduling System
The Graphical Scheduler is the latest of software products developed by SAGE for the transit industry. It was specifically designed to run on a micro-computer taking advantage of the latest...
Los Angeles and Long Beach Harbors Tidal Circulation Study
Expansion of harbor facilities frequently involves placement of additional landfill and the deepening of channels and mooring areas. A numerical tidal circulation model was used in the...
Street Fares
An argument is made for imposing user fees to amass funds for repair and maintenance of local roads and streets. These infrastructure services have to compete for local general property...
How to Use a Transit Consumer Information System
This paper reports the results of an effort to implement a consumer information system in a small urban area. The system was designed to periodically report the travel patterns and viewpoints...
Computerized Information for Selecting Protected Streamflow
For developing criteria for protected flow (the flow below which water withdrawals for offstream uses are not permitted) for streams in a relatively hydrologically homogeneous region,...
Computer Aided Design of Ground-Water Monitoring Programs
Preliminary evaluation of flow patterns and plume migration by computer simulation aids in determining the spacing of monitoring devices perpendicular to the flow direction, the location...
Automated People Movers?The Need for Flexibility and Clarity
The Airtrans System at Dallas/Ft. Worth Airport is the best example available of how an automated people mover (APM) might function in an urban setting. An examination of Airtrans shows...
Regional Planning Models Used in Subarea Windows
The typical regional travel-forecasting model has historically been confined to use on a mainframe computer. In an effort to reduce costs and allow computer hardware options, a three-tiered...
Use of a Simplified Urban Traffic Forecasting Procedure for Project Analysis
This paper presents New York State Department of Transportation's experience with the calibration and testing of a simplified procedure for estimating urban traffic at the...
Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...
