Solving The First Mile/ Last Mile Problem: Electric Scooter And Dockless Bicycles Are Positioned To Provide Relief To Commuters Struggling With A Daily Commute, Kelly Grosshuesch

William & Mary Environmental Law and Policy Review

Commuters in cities across the United States struggle to find ease in their daily commute. Public transportation no longer provides residents with an adequate and reliable source of transportation.1 For many commuters, getting to and from nodes of public transportation is difficult and a deterrent from using public or shared transportation instead of driving.2 This, therefore, increases vehicle congestion and car emissions in cities. While multiple new technologies and innovations have emerged to attempt to help commuters with the trip to and from public transportation, most have fallen short.3 But two new innovations that have gained major ...

Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John Macarthur, Aaron Golub

TREC Friday Seminar Series

As transit agencies modernize their fare payment systems, opportunities to pay with cash are reduced. This speeds boarding and lowers the cost of operations while also creating new sources of ridership data. Arguably, service is improved for riders as well as payment systems could work across modes, creating a more seamless and simplified experience. Still, about 15% of adults in the United States are without a bank account or credit card account and many rely on restrictive cell-phone data plans or don’t have access to a smartphone. These shares are even higher for public transit users. These un- and ...

The Impact Of Location On Healthcare Access For Individuals With Disabilities, Addison Kimber 2020 University of Connecticut

The Impact Of Location On Healthcare Access For Individuals With Disabilities, Addison Kimber

Honors Scholar Theses

This paper analyzes healthcare access for individuals with disabilities living in rural areas. In current political discussion, we typically think of insurance coverage as the metric to analyze healthcare access. However, as demonstrated by studies of healthcare in the United Kingdom, people with disabilities continue to face barriers to health care even with universal healthcare systems. In particular, individuals in rural areas have less healthcare access than urban residents. This is due to factors including socioeconomic status, insurance coverage, access to competent care, and transportation. This study aims to understand if disability status exacerbates the issue of access in rural ...


Mount Mazama Ash Offers Sustainable Solution For Ada Accessibility On Unpaved Trails, Matthew D. Sleep, Damian K. Matzen 2020 Oregon Institute of Technology

Mount Mazama Ash Offers Sustainable Solution For Ada Accessibility On Unpaved Trails, Matthew D. Sleep, Damian K. Matzen

TREC Project Briefs

National Institute for Transportation and Communities (NITC) researcher Matthew Sleep of Oregon Tech investigated whether Mazama ash could be used in place of portland cement, as a natural pozzolan. Results indicate that it can—and unpaved trail surfaces made with Mazama ash are actually firmer and more durable than those made with portland cement alone. Such trails can provide a reliable surface for wheeled mobility devices.


Ada Accessible Trail Improvement With Naturally Occurring, Sustainable Materials, Matthew D. Sleep, Damian K. Matzen 2020 Oregon Institute of Technology

Ada Accessible Trail Improvement With Naturally Occurring, Sustainable Materials, Matthew D. Sleep, Damian K. Matzen

TREC Final Reports

The Americans with Disabilities Act (ADA) provides specific guidelines and requirements that must be met in terms of accessibility. However, in the case of unpaved trails, the requirements are less defined. An ADA trail must be firm, stable and slip resistant. Some compacted aggregate material may meet this definition, but degrade over time and can no longer be ADA compliant. The benefits of using unpaved surfaces for ADA trails include fit to the natural environment, cost, sustainability and environmental benefits such as increased permeability. If an unpaved surface can be improved with the use of an additive, more could be ...

Learning & Planning For Self-Driving Ride-Hailing Fleets, Jack Morris 2020 William & Mary

Learning & Planning For Self-Driving Ride-Hailing Fleets, Jack Morris

Undergraduate Honors Theses

Through simulation, we demonstrate that incorporation of self-driving vehicles into ride-hailing fleets can greatly improve urban mobility. After modeling existing driver-rider matching algorithms including Uber’s Batched Matching and Didi Chuxing’s Learning and Planning approach, we develop a novel algorithm adapting the latter to a fleet of Autos – self-driving ride-hailing vehicles – and Garages – specialized hubs for storage and refueling. By compiling driver-rider matching, idling, storage, refueling, and redistribution decisions in one unifying framework, we enable a system-wide optimization approach for self-driving ride-hailing previously unseen in the literature. In contrast with existing literature that labeled driverless taxis as economically infeasible ...

The Adoption Of Zero-Emissions Vehicles By Low-Income Consumers In California: An Outcome Evaluation Of The Clean Vehicle Rebate Project, Julie Nguyen

Master's Projects

Is the Clean Vehicle Rebate Project (CVRP) program achieving its planned outcomes of accelerating the adoption of Zero-Emissions Vehicles (ZEVs) by low-income consumers in California? This research will evaluate what effect additional CVRP rebates provided to low-income consumers have on their adoptions of ZEVs. The purpose of this research is to determine whether the CVRP rebates are making it feasible and compelling enough for low-income consumers to adopt ZEVs at a rate that will lead to California meeting its greenhouse gas reduction goals.
