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 ...
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 ...
Integration of a GIS and an expert system for freeway incident management
(Virginia Tech, 1996-09-15)
Congestion due to traffic accidents and incidents can be reduced through effective freeway incident management. However, this is plagued by a number of problems and requires a high level of expertise and coordination among ...
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. ...
The Use of GIS for Integrated Watershed Analysis
(Virginia Tech, 2000-04-26)
Practitioners of watershed management are increasingly turning to computer models to understand and make decisions about the diverse problems that occur in the watershed. Such models can provide insight into how human ...
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 ...
Analysis of transit service areas using geographic information systems
(Virginia Tech, 1998)
An Analysis of Emergency Vehicle Crash Characteristics
(Virginia Tech, 2003-08-07)
Crash data suggests that intersections are areas producing conflicts among the various road users because of entering and crossing movements. Traffic signal control systems may not always be sufficient in preventing ...
Web-enabled Spatial Decision Support System for Interdisciplinary Watershed Management
(Virginia Tech, 2002-09-30)
The development and use of web-enabled tools for watershed modeling and decision-making have gained popularity lately with the increase in internet speed and accessibility. Most of the web-enabled tools available today ...
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 ...
