Potable Water Leakage Prediction And Detection Using Geospatial Analysis, Jacob Tittle
Potable Water Leakage Prediction And Detection Using Geospatial Analysis, Jacob Tittle
Electronic Theses and Dissertations
Due to increasing water treatment costs and conservation needs, traditional water loss analysis and acoustic leak detection methods are becoming heavily scrutinized by water utilities. This study explores water loss in Johnson City, Tennessee and how geospatial data analysis techniques improve water loss mitigation. This project uses sample water system pressure data and ordinary kriging spatial interpolation methods to identify leakage areas for further investigation. Analysis of existing geographic information system (GIS) water utility datasets with interpolated hydraulic grade values at sample water pressure points produce manageable survey areas that pinpoint areas with possible water leakage. Field detection methods, including …
A Gis Safety Study And A County-Level Spatial Analysis Of Crashes In The State Of Florida, Ali Darwiche
A Gis Safety Study And A County-Level Spatial Analysis Of Crashes In The State Of Florida, Ali Darwiche
Electronic Theses and Dissertations
The research conducted in this thesis consists of a Geographic Information Systems (GIS) based safety study and a spatial analysis of vehicle crashes in the State of Florida. The GIS safety study is comprised of a County and Roadway Level GIS analysis of multilane corridors. The spatial analysis investigated the use of county-level vehicle crash models, taking spatial effects into account. The GIS safety study examines the locations of high trends of severe crashes (includes incapacitating and fatal crashes) on multilane corridors in the State of Florida at two levels, county level and roadway level. The GIS tool, which is …
Applying Log-Linear Models And Gis To Study The Safety Of Pedestrians And Bicyclists : A Case Study Of Orange County School Children, Sai Srinivas Chundi
Applying Log-Linear Models And Gis To Study The Safety Of Pedestrians And Bicyclists : A Case Study Of Orange County School Children, Sai Srinivas Chundi
Electronic Theses and Dissertations
Abstract Pedestrian /bicycle safety of school children has been a growing menace that has been attracting attention from transportation professionals, school boards, media and the community all over the country. As such there has been a necessity to identify critical variables and assess their importance in pedestrian/bicycle crashes occurring in and around school zones. The current study is an endeavor in this direction. The literature review identified some studies that were conducted on school zone safety related to pedestrian/bicyclist crashes. Most of the studies pertained to crashes with all age groups. There have been few studies with emphasis only on …
