Understanding Technology-Based Exclusion In Emerging Smart Mobility Systems, John MacArthur, Aaron Golub 2020 Portland State University

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 ...

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 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 ...

Curb-Sided: How Technology Disrupts The American Transportation Planning Process, Mary Angelica Painter 2020 University of Missouri-St. Louis

Curb-Sided: How Technology Disrupts The American Transportation Planning Process, Mary Angelica Painter

Dissertations

The disruptive arrival of Uber, Lyft, and other transportation network companies (TNCs) into American cities ignited arguments on how policy-makers should regulate such entities. Policy debates started among policymakers, companies, and existing industries and interests. In attempts to persuade policy, actors adopted a variety of language and used different levels of government to achieve policy goals. In almost all cases, TNCs were able to gain favorable policy through image framing and venue shopping – the key components to Punctuated Equilibrium Theory (PET). This analysis looks at the policy process of three American cities: Chicago, IL, St. Louis, MO, and Austin, TX ...


Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong 2020 California State University, Fresno

Moving Toward Equitable Transit-Oriented Developments By Integrating Transit And Housing, Hongwei Dong

TREC Friday Seminar Series

Prior studies show that transit-oriented developments (TODs) increase property values and raise property tax revenue. Property owners reap economic benefit from TODs and public officials use it as evidence to justify the high cost of rail transit. However, renters, who rely on transit more than homeowners, may have to pay higher rent to live in TODs. The location affordability index at the neighborhood level suggests that renters can also benefit from TOD by saving money on transportation costs. Recent studies at the individual level, however, found little evidence that living in TODs reduces transportation expenditure. Using rental data scraped from ...

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier 2020 Alta Planning + Design

Bus-Bike Designs For The Division Transit Project, Derek Abe, Jesse Stemmier

TREC Friday Seminar Series

This seminar is brought to you by the Oregon chapter of the Association of Pedestrian and Bicycle Professionals (APBP), with support from TREC at Portland State.

Transit stops and stations are a confluence of complementary and competing activities - pedestrians accessing businesses, passengers boarding and alighting, and bicyclists zipping through to their destinations. People are moving in different directions, at different speeds, and need to be able to navigate this space safely and comfortably. A common point of conflict is the bus/bicycle interaction when a transit stop is adjacent to a bike lane. Designs for integrating pedestrian and bicycle facilities ...


Copenhagenization: The Spread Of The Copenhagen Cycling Gospel; A Case Study In Urban Policy Mobility, Rozaliya Momot 2020 Trinity College

Copenhagenization: The Spread Of The Copenhagen Cycling Gospel; A Case Study In Urban Policy Mobility, Rozaliya Momot

Senior Theses and Projects

Copenhagen is synonymous with biking culture, and is one of the first things people think about in relation to the Danish capital. It has become constructed as a policy model for urban planning, especially for cycling policy, and cities around the world look to it as a "best practice" example. As American cities attempt to change their transportation dynamics and encourage alternate forms of transportation, they increasingly look to cycling as a solution, and refer to Copenhagen as a model. In this thesis, I examine how this model has been packaged and exported by influential Danish consultants and public figures ...
