Local Planning And High-Speed Rail: Responses And Perceptions In A Developing Amtrak Corridor, John-Luke D'Ambrosio
Local Planning And High-Speed Rail: Responses And Perceptions In A Developing Amtrak Corridor, John-Luke D'Ambrosio
Masters Theses
Incremental speed increases have been a main focus of Amtrak in recent years. Now operating at 110 mph within three different service lines in the United States, Amtrak is making progress toward achieving maximum speeds within rail corridors. This study focuses on Amtrak’s Wolverine service line which operates daily passenger rail service between Chicago, Illinois and Detroit/Pontiac, Michigan. Specifically, this study will look at six cities connected by this service that are east of Chicago. The six cities examined in this research are Hammond, Indiana, Michigan City, Indiana, New Buffalo, Michigan, Niles, Michigan, Dowagiac, Michigan, and Kalamazoo, Michigan. This segment …
Integrating Social Media In The Development Of A Special Event Population Dynamics Model, Kelly Michelle Sims
Integrating Social Media In The Development Of A Special Event Population Dynamics Model, Kelly Michelle Sims
Masters Theses
With society’s increasing participation in social media, scientists now have access to new sources of data that reflect our daily activities in space and in time. Such data are plentiful and, more notably, at an unprecedented granular level. The ability for users to capture and express their geolocation through their phones’ global positioning system (GPS) or through a particular location’s hashtag or Facebook Page provides a great opportunity for modeling spatiotemporal population dynamics. High resolution population models and databases for episodic special events can be extremely useful for enhancing emergency management and response. This research assesses the feasibility of improving …
Assessing Survivability Of The Beijing Subway System, Yan Li
Assessing Survivability Of The Beijing Subway System, Yan Li
Masters Theses
The assessment of survivability is a common topic in critical network infrastructure research. In order to examine the critical components whose disruptions can cause huge system degradation, many measures have been approached to depict the characteristics of network systems. Serving more than ten million passengers a day, the Beijing subway system, which ranks third in the world for its length and annual ridership, raises survivability issues in the face of potential disruptions of network components along with its constantly increasing complexity. In this research, we provide an accessibility-based survivability measure with which to explore how potential outages of network components …
Comparing Models Of Demographic Subpopulations, Jessica Jones Moehl
Comparing Models Of Demographic Subpopulations, Jessica Jones Moehl
Masters Theses
Understanding specific multi-dimensional demographics of populations in the United States at high resolutions is made difficult by the restriction of data released by the Census Bureau because of privacy concerns. Efforts to model these subpopulations have been increasing in recent years. These modeled populations have applications in decision making at all levels of government as well as in academia and the private sector. Two models have shown promising techniques for incorporating multiple levels of data to model sub populations in a meaningful way. These models, the Copula Model by Kao et al. (2012) and the Penalized Maximum Entropy Model by …
Predictive Modeling In The Search For Vertebrate Fossils: Geographic Object Based Image Analysis (Geobia) In The Eocene Of Wyoming, Bryan Bommersbach
Predictive Modeling In The Search For Vertebrate Fossils: Geographic Object Based Image Analysis (Geobia) In The Eocene Of Wyoming, Bryan Bommersbach
Masters Theses
The development and testing of predictive models for identifying productive fossil localities represents a promising interdisciplinary endeavor among geographic information scientists, paleoanthropologists, and vertebrate paleontologists. This thesis analyzed high resolution (2m spatial resolution) commercial satellite imagery from the Worldview-2 satellite of five areas of the Great Divide Basin using a GEographic Object-Based Image Analysis (GEOBIA) technique, which segments the image into spectrally homogeneous, multi-pixel image objects. In addition to allowing statistical analysis of the spectral characteristics of the image objects, GEOBIA techniques also let analysts incorporate expert knowledge and contextual information to improve classification accuracy. The spectral characteristics of the …
An Analysis Of The Patterns Of Crime And Socioeconomic Status Visualized Through Self-Organized Maps, Jason Carlin Kaufman
An Analysis Of The Patterns Of Crime And Socioeconomic Status Visualized Through Self-Organized Maps, Jason Carlin Kaufman
Masters Theses
This work is research to explore the association of spatial patterns between crime and socioeconomic status (SES) through the use of self-organized maps (SOM). It had been found that the spatial patterns of crime could be associated with those of socioeconomic, and this work sought to further these analyses in order to better understand how crime patterns and SES were related. To explore this association, patterns of crime and SES were examined in three cities: Nashville, TN; Portland, OR; and Tucson, AZ. Three SOMs were used in each city: one to analyze the patterns of crime, a second to analyze …
