Distributed Hydrologic Modeling of the Upper Roanoke River Watershed using GIS and NEXRAD
(Virginia Tech, 2003-03-27)
Precipitation and surface runoff producing mechanisms are inherently spatially variable. Many hydrologic runoff models do not account for this spatial variability and instead use "lumped" or spatially averaged parameters. ...
Analysis of transit service areas using geographic information systems
(Virginia Tech, 1998)
Development of Optimal Migration Plan for New Traffic Signal Controllers Using Gis and Multi-Criteria Decision Making
(Virginia Tech, 2010-07-01)
Signal Replacement decisions are often made based on the experience of the Traffic Engineers. These decisions are made while considering the deployment time of the system, the new technology available, and the performance ...
Web-Based Platform for Force Main Infrastructure Asset Management
(Virginia Tech, 2016-08-13)
Asset management of force main infrastructure entails accurate prediction of the condition of the system to operate and maintain at the lowest overall costs. In this thesis report, guidelines for asset management of force ...

Development of Standard Geodatabase Model and its Applications for Municipal Water and Sewer Infrastructure
(Virginia Tech, 2010-02-03)
Availability of organized data is required for accurate prediction of structural or functional deterioration in sewer and water pipes. Toward this end, GIS provides a means for viewing, understanding, interpreting, and ...
A Model to Convert Airport Geographic and Geometric Information into a Node-Link Network
(Virginia Tech, 2015-01-17)
An airport node-link network model is an important input for most airport simulation models. Developing, maintaining and updating detailed airport surface node-link models require significant work. A model to convert airport ...
Incident response and application of Geographical Information Systems (GIS)
(Virginia Tech, 1996-07-25)
Traffic congestion has been identified as the one of the most serious problems in urban transportation. Not much can be done in finding solutions to recurring congestion problem. As a part of ITS research in the 90's, a ...
Effects of Stream Order and Data Resolution on Sinuosity Using GIS
(Virginia Tech, 2008-04-29)
This research focuses on estimation and analysis of stream sinuosity using GIS. Fifty-five streams including 13 streams of order 0, 17 streams of order 1, 15 streams of order 2 and 10 streams of order 3 in Virginia were ...
Leveraging Technology to Add Value to a Phase II NPDES Permit
(Virginia Tech, 2013-06-03)
In 1999, Phase II of the National Pollutant Discharge Elimination System engaged operators of small Municipal Separate Storm Sewer Systems (MS4) in the control of runoff from urban areas. The complex task of urban runoff ...
