Why We Should Reuse Wastewater, Bridget Sarver
Certified Public Manager® Applied Research
As population and industry grow, the need to reuse wastewater is growing. Aquifers are often the dominant water supplies to surrounding areas. The levels of those aquifers are declining each year. Water loss affects many things like water wells, lakes, and rivers. Lakes and rivers that are used as water sources are seeing a decline in levels. Low water levels and drought occur because of the changing water cycle. Heavy rain and runoff can help refill lakes and rivers; however precipitation does not always fall back on the area that it evaporated from. By reusing wastewater, we will be saving ...

Our Streets: Increasing Equity In Active Transportation Planning Through Community Outreach, Jordan Hoy
Master's Projects and Capstones
ABSTRACT Significant research has demonstrated that active transportation infrastructure is essential for the growth and livability of San Francisco: it increases access to economic opportunities, promotes overall improved public health, encourages mobility without contributing to roadway congestion, prevents traffic injuries and fatalities, and supports the sustainability goals of the city. Despite the fact that communities of color will benefit the most from active transportation infrastructure development, historical disenfranchisement in tandem with a lack of diverse representation within public participation contributes to an inequitable distribution of walking and biking investments throughout the city of San Francisco. While research shows that Black ...

Because Potato, Candice Evers
MFA in Illustration & Visual Culture
This thesis project explores the phenomenological qualities of the internet; asking, since the internet is difficult to grasp, what other modes of investigation might we have available? Using an investigative framework set forth by Jack Halberstam, this thesis declines to come to knowledge solely through understanding the formal, the structural, the highly visible and mainstream. The literature that I have gathered provides a range of modes for interrogating the simultaneously central and inconsequential subject of my thesis itself: the potato. Juxtaposing the physical, political and material conditions of the potato the internet’s least academic mode of knowing: the meme ...

Examining The Effects Of Precision Scheduled Railroading On Intercity Passenger And High-Speed Rail Service, John G. Green, Francis J. Miller
Mineta Transportation Institute Publications
More than just scheduling terminal-to-terminal trips for trains, “Precision Scheduled Railroading” (PSR) creates entire point-to-point trip plans for individual railroad shipments. Since precision execution was first put into practice, the benefits to shipment arrival reliability and to freight railroads’ profitability have been demonstrated by its use in several Class One freight railroads. However, the effects of the PSR operating strategy on passenger railway operations in shared freight/passenger corridors has not been studied in detail. This research examines the effects of PSR railroad operations on passenger railways, including measuring “Host Railroad Minutes of Delay per 10,000 Train-Miles” and “On-Time ...

Congestion Costs And Scheduling Preferences Of Car Commuters In California: Estimates Using Big Data, Jinwon Kim, Jucheol Moon
Mineta Transportation Institute Publications
On average, California car commuters waste 4–5 minutes per morning commute due to congestion. Multiplied across all California car commuters, those few minutes entail a yearly total of approximately 2.3 billion hours of time wasted, costing 6 billion dollars. The objective of this study is to quantify congestion costs and determine how commuters adapt to the level of congestion they face (i.e., commuters’ scheduling utility functions). To that end, this research developed a model of trip scheduling under congestion to construct California commuters’ travel-time profiles, i.e., the menu of travel times that each individual would likely ...

The San Francisco Bay Area is one of the most progressive transportation regions in the deployment of high-capacity transit and use of policies to encourage active transportation. Yet like many other metro regions, there remains a dearth of knowledge on the abundance and location of parking infrastructure supply. Parking infrastructure remains one of the least catalogued infrastructure but is perhaps the most spatially dominating set of assets. This research estimates the extent and location of parking supply, including on-street and off-street spaces for the nine-county Bay Area. This parking space inventory is the most detailed assessment of parking infrastructure produced ...

Municipal Fiber In The United States: A Financial Assessment, Christopher S. Yoo, Jesse Lambert, Timothy P. Pfenninger
Faculty Scholarship at Penn Law
Despite growing interest in broadband provided by municipally owned and operated fiber-to-the-home networks, the academic literature has yet to undertake a systematic assessment of these projects’ financial performance. To fill this gap, we utilize municipalities’ official reports to offer an empirical evaluation of the financial performance of every municipal fiber project in the U.S. operating in 2010 through 2019. An analysis of the actual performance of the resulting fifteen-project panel dataset reveals that none of the projects generated sufficient nominal cash flow in the short run to maintain solvency without infusions of additional cash from outside sources or debt ...
