Connected Simulation For Work Zone Safety Application, Vahid Balali

Mineta Transportation Institute Publications

Every year, over 60,000 work zone crashes are reported in the United States (FHWA 2016). Such work zone crashes have resulted in over 4,400 fatal and 200,000 non-fatal injuries in the last 5 years (FHWA 2016, BLS 2014). Apart from the physical and emotional trauma, the annual cost of these injuries exceeds $4 million-representing significant wasted resources. To improve work zone safety, this research developed a system architecture for unveiling high-risk behavioral patterns among highway workers, equipment operators, and drivers within dynamic highway work zones. This research implemented the use of a connected virtual environment, which is ...

Contracting Strategies: A Different Approach To Address Long-Term Performance, Maria Calahorra-Jimenez

Mineta Transportation Institute Publications

For cost-efficiency, public safety, and sustainability, improving long-term performance in highway projects is imperative for public administrations. Project delivery and procurement methods provide an opportunity to align design and construction processes with this goal. While previous studies have explored whether project delivery methods impact the long-term performance of highway projects, these studies did not focus on how core elements within project procurement relate to long-term performance. Thus, to fill this gap, this research explores how and to what extent long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, the team conducted content analysis on ...

Estimating The Economic Impacts Of Transportation-Related Supply Chain Disruptions In The Post-Earthquake Environment, Divya Chandrasekhar, Sua Kim, John Downen, Joshua Spolsdoff

TREC Final Reports

Transportation systems play a critical role in maintaining supply chains for effective post-disaster recovery. Modeling the potential economic impact of transportation-related disruptions, therefore, is an important step to promoting pre-event community wide recovery and resilience planning. But existing supply chain and economic impact models are cost prohibitive and overly sophisticated for use by public sector entities with limited resources. There is also limited understanding of how small and medium enterprises (SMEs) adjust to post-disaster transportation disruption and how this experience influences their future preparedness for similar events. This project had two objectives: (1) to analyze the economic impact due to ...


Why We Should Reuse Wastewater, Bridget Sarver 2022 Stephen F. Austin State University

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 2022 The University of San Francisco

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 2022 Washington University in St. Louis

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 ...
