Full Potential Of Future Robotaxis Achievable With Trip-Based Subsidies And Fees Applied To The For-Hire Vehicles Of Today, John Niles
Mineta Transportation Institute
As described by Grush and Niles in their textbook, The End of Driving: Transportation Systems and Public Policy Planning for Autonomous Vehicles, there are two distinct market states for the future of automobility as vehicles become increasingly automated. The first, Market-1, is comprised of all vehicles that are manufactured and sold to private owners and used as household vehicles. This private consumer fleet will—through automated driver assistance systems (ADAS)—be increasingly capable of hands-off operation, even self-driving in certain environments such as limited-access expressways. The second category, Market-2, represents all the vehicles made expressly for the service market, i.e., roboshuttles and …

Understanding Factors Affecting Arterial Reliability Performance Metrics, Jason C. Anderson, Rohan Sirupa, Sirisha Kothuri, Avinash Unnikrishnan
TREC Final Reports
In recent years, the importance of travel time reliability has become equally important as average travel time. However, the majority focus of travel time research is average travel time or travel time reliability on freeways. In addition, the identification of specific factors (i.e., peak hours, nighttime hours, etc.) and their effects on average travel time and travel time variability are often unknown. The current study addresses these two issues through a travel time-based study on urban arterials. Using travel times collected via Bluetooth data, a series of analyses are conducted to understand factors affecting reliability metrics on urban arterials. Analyses …

Effects Associated With The Deployment Of Autonomous And Connected Vehicles: Insights From Las Vegas, Nv, Sarah Dennis
UNLV Theses, Dissertations, Professional Papers, and Capstones
Autonomous and connected vehicles (ACVs) are quickly evolving and becoming part of our transportation systems. Adoption of this technology is largely dependent on public perceptions and comfort. The objective of this study was to evaluate public perceptions of ACVs and gain knowledge regarding potential use and important aspects towards acceptance of ACVs. Specifically, the differences in perceptions of people who have ridden an ACV are compared to those who have not. A stated preference approach was utilized, as this is an emerging technology. Two different survey questionnaires were distributed. The first survey was distributed to participants considered to be members …

The War On Winter: How Americans Put Down Roots On The Northern Plains, 1854-1949, Daniel J. Fischer
Graduate Theses and Dissertations
My dissertation is a study of how the United States was able to expand onto the Northern Great Plains, consisting of the Dakotas, Nebraska, and the eastern parts of Wyoming and Montana, between 1854 and 1949 despite the threat to property, comfort, and survival posed by the region’s harsh winters, which brought intense cold, large snowdrifts, and blinding blizzards. This dissertation argues that five tools – government programs, rapidly changing technology, imagination, strong local communities, and toughness – allowed native-born Americans and European immigrants to survive and become increasingly secure in the region. But it also argues that severe gaps …

Minimodal: Dimensional Domain Of Miniature Shipping Containers For Intermodal Freight Transportation, Lee Stapley
Ursidae: The Undergraduate Research Journal at the University of Northern Colorado
This study explores the feasibility of miniature shipping container usage within existing intermodal transportation (IT) supply chains. Smaller intermodal container shipments may help realign freight shipments with the most efficient transportation mode, rail. These containers embolden the dimensional domain (DD) of shipping. The shipping container dimensional domain (container size variation and modal fluidity) is widespread and results in shipments that are often larger or more infrequent than needed. The DD impacts transport mode, shipping frequency, shipment velocity, intermodal supply chain accessibility, and regional shipping networks. This study suggests that container size impacts the DD and, therefore, mode choice. As miniature …

Is There An Economic Case For The Olympic Games?, Chris Dempsey, Victor Matheson
Economics Department Working Papers
The Olympic Games are a major undertaking that promise both large costs and potentially large benefits to host cities. This paper lays out the potential economic benefits of hosting the Olympics and details how, in the vast majority of cases, these gains are unlikely to cover the costs of hosting the event. The ideas are then applied to the experience of Boston in its ultimately unsuccessful bid for the 2024 Summer Olympics.

Evaluating The Effectiveness Of A School-Based Intervention On Driving-Related Carbon Emissions Using Real-Time Transportation Data, Eugene Cordero, Diana Centeno
Mineta Transportation Institute
The development of tools that can measure the efficiency of individual driving behaviors offers unique opportunities to encourage drivers towards more efficient driving behaviors. As states make progress towards reducing carbon emissions through the adoption of renewable energy for electricity generation, transportation remains the largest sources of carbon emissions. Although numerous local or regional campaigns have encouraged consumers to conserve energy at home and at work, less interest has been shown in encouraging drivers to adopt more energy efficient driving behaviors. In this study, a smartphone application was used to gather driving data (e.g., hard accelerations, hard braking and time …

The Impact Of Zev Adoption On California Transportation Revenue, Martin Wachs, Hannah King, Asha Weinstein Agrawal
Mineta Transportation Institute
Former California Governor Jerry Brown set an ambitious target for the state to reach five million zero-emission vehicles (ZEVs) by 2030. The policy is intended to reduce greenhouse gas emissions, but progress toward this target will also affect future state-generated transportation revenues collected from vehicle owners and operators. A central concern for policymakers is to estimate the magnitude of the revenue impact. We used a simple spreadsheet model to project future transportation revenue in California through 2040 under two scenarios. The first scenario assumes that ZEV ownership continues at its historical rate of net increase, approximately 26,000 vehicles per year …

Model And Analysis Of Labor Supply For Ride-Sharing Platforms In The Presence Of Sample Self-Selection And Endogeneity, Hao Sun, Hai Wang, Zhixi Wan
Research Collection School Of Computing and Information Systems
With the popularization of ride-sharing services, drivers working as freelancers on ride-sharing platforms can design their schedules flexibly. They make daily decisions regard- ing whether to participate in work, and if so, how many hours to work. Factors such as hourly income rate affect both the participation decision and working-hour decision, and evaluation of the impacts of hourly income rate on labor supply becomes important. In this paper, we propose an econometric framework with closed-form measures to estimate both the participation elasticity (i.e., extensive margin elasticity) and working-hour elasticity (i.e., intensive margin elasticity) of labor supply. We model the sample …
