Equity In Accessibility, A Case Study Of City Of Sacramento, Meredith C. Milam 2021 California Polytechnic State University, San Luis Obispo

Equity In Accessibility, A Case Study Of City Of Sacramento, Meredith C. Milam

City and Regional Planning

This paper is a Geographic Information Systems (GIS) spatial analysis of the transportation accessibility and equity in Sacramento, California. A literature review examines discriminatory regulatory policies in the 1900s that wrote racial segregation into law. The effects of these policies have lasting effects on spatial dispersal of people and create barriers to accessibility and therefore result in inequitable transportation systems. The accessibility and equity analysis in Sacramento explores demographic data, job concentration and available modes of transportation, and commuter data. The results of the analysis suggest that there is no “one-size-fits-all” approach when it comes to measuring accessibility and equity ...


Parking Spaces To People Places: Report, Shawn Canny, Natalie Knowles, Arva Hussain, Ann Le, Megan Doherty, Elizabeth Cox 2021 Portland State University

Parking Spaces To People Places: Report, Shawn Canny, Natalie Knowles, Arva Hussain, Ann Le, Megan Doherty, Elizabeth Cox

Master of Urban and Regional Planning Workshop Projects

In March of 2020, public life would undergo a major transformation as a result of the COVID-19 pandemic. Cities throughout the U.S. were grappling with the impacts to their business communities, their local economies, and urban life as indoor places became vectors for disease. As a result of the decline in economic activity, there was a dramatic reduction in automobile use—opening up an opportunity to rethink how paved surfaces, specifically parking space and streets. It encouraged many localities to quickly close down streets and reclaim them for business activity. Adapting space that had been designed to move traffic ...


Transportation And Gentrification: Impacts On Low-Income Black Households In Portland, Steven Howland 2021 Portland State University

Transportation And Gentrification: Impacts On Low-Income Black Households In Portland, Steven Howland

TREC Friday Seminar Series

Portland’s Black population has been heavily impacted by gentrification in the historic Albina community. Nearly half of Portland’s Black population lives in the area east of 82nd Ave, known as East Portland. This has had substantial impacts on both Black households that can continue living in Albina and those living in East Portland. The suburban-esque built environment of East Portland makes it difficult to get around and reach basic necessities. Those living in Albina have taken on exorbitant rents. Both groups suffer from a geographic divide that has made it difficult to rely on family and friends for ...


Mass Transit Policy: Responding To Covid-19, Susan E. Baer, George R. Larkin 2021 Walden University

Mass Transit Policy: Responding To Covid-19, Susan E. Baer, George R. Larkin

Journal of Social Change

Mass transit is vital to daily life in U.S. cities and many other cities throughout the world. Mass transit systems are vulnerable to pandemics like COVID-19 and other less serious threats. Post COVID-19 mass transit policy must be different than its predecessors if mass transit is to provide a reliable, sustainable, and equitable means of transportation. Future mass transit systems will be the outcome of public health, technological, economic, and political considerations. This paper provides an initial attempt to identify and discuss these four considerations as most relevant to the development of an equitable and efficient mass transit policy ...

Senior Honors Projects

DANIELLE BEATRICE (English; Philosophy; Business) URI and Its Students: A Contract for the Provision of a Safe Environment

Sponsor: Judith Swift (Communication Studies, Coastal Institute)

When students begin to attend college, they expect to be consumed with busy schedules, heavy workloads, and an exciting social life. Students do not anticipate being in dangerous situations. However, this does not mean that such situations do not occur. Therefore, it is essential to teach students to be active participants in educating themselves and their peers regarding prevention and response to emergency situations. My Honors Project aims to increase the awareness of safety-related issues ...

Comparing Twitter And Lodes Data For Detecting Commuter Mobility Patterns, Jochen Albrecht, Andreas Petutschnig, Laxmi Ramasubramanian, Bernd Resch, Aleisha Wright

Mineta Transportation Institute Publications

Local and regional planners struggle to keep up with rapid changes in mobility patterns. This exploratory research is framed with the overarching goal of asking if and how geo-social network data (GSND), in this case, Twitter data, can be used to understand and explain commuting and non-commuting travel patterns. The research project set out to determine whether GSND may be used to augment US Census LODES data beyond commuting trips and whether it may serve as a short-term substitute for commuting trips. It turns out that the reverse is true and the common practice of employing LODES data to extrapolate ...


Via2g Microtransit Pilot Evaluation, Anne Brown, Alice Grossman, Lucy Noble 2021 University of Oregon

Via2g Microtransit Pilot Evaluation, Anne Brown, Alice Grossman, Lucy Noble

Mineta Transportation Institute Publications

Google partnered with Via to launch an on-demand microtransit called Via2G between January and March 2020. The pilot provided employees with free travel to/from two of its offices in suburban, congested Silicon Valley. While the pilot was cut short due to COVID-19, rider participation grew steadily during operation. Of trip requests, 8,636 (87.8%) resulted in a ride offer. Unfulfilled requests were primarily outside of pilot operating times or when rider demand exceeded driver supply. Most users (72%) completed at least two trips, although recurring users were less likely to complete errands on the commute and fewer had ...

Ability Of Bay Area Cities To Accommodate Plug-In Electric Vehicles: A Process Evaluation, Chi-Pei Fang 2021 San Jose State University

Ability Of Bay Area Cities To Accommodate Plug-In Electric Vehicles: A Process Evaluation, Chi-Pei Fang

Master's Projects

Numerous studies have mentioned that there are lots of factors that may affect electric vehicle adoption, including residents’ income, manufactures’ behavior, mass transportation system, and so on (Larson et al., 2014; Majumdar, 2005; Millard-Ball, 2012; Azevedo et al., 2017; Liao, 2018). While the issue of electric vehicle adoption has been explored in a wide range of contexts, there is a limited number of studies to understand how the policies are implemented from the perspective of a “city.”

In recent years, several studies have started to pay more attention to a city's role in electric vehicle adoption (Baker et al ...

Effects Of The Transportation And Climate Initiative On The Maine Economy: An Analysis Of Cap-And-Invest And Its Heterogeneous Impacts On Rural And Urban Households, William L. Somes

Honors College

In December 2020, a memorandum of understanding (MOU) was released by the Transportation and Climate Initiative Program (TCI-P), a collaboration of 13 jurisdictions in the New England and Mid-Atlantic regions of the United States. Modeled on the Regional Greenhouse Gas Initiative (RGGI), the TCI-P follows a cap-and-invest framework to reduce emissions from the transportation sector by 26% from 2022 to 2032. Since the TCI-P is expected to raise the price of gasoline by 5¢ to 9¢ per gallon, there has been concern that some populations may be disproportionately affected. The present research studies the potential heterogeneous impacts of the TCI-P ...


Tripdecoder: Study Travel Time Attributes And Route Preferences Of Metro Systems From Smart Card Data, Xiancai TIAN, Baihua ZHENG, Yazhe WANG, Hsao-Ting HUANG, Chih-Cheng HUNG 2021 Singapore Management University

Tripdecoder: Study Travel Time Attributes And Route Preferences Of Metro Systems From Smart Card Data, Xiancai Tian, Baihua Zheng, Yazhe Wang, Hsao-Ting Huang, Chih-Cheng Hung

Research Collection School Of Computing and Information Systems

In this paper, we target at recovering the exact routes taken by commuters inside a metro system that are not captured by an Automated Fare Collection (AFC) system and hence remain unknown. We strategically propose two inference tasks to handle the recovering, one to infer the travel time of each travel link that contributes to the total duration of any trip inside a metro network and the other to infer the route preferences based on historical trip records and the travel time of each travel link inferred in the previous inference task. As these two inference tasks have interrelationship, most ...


A Smarter Way To Manage Mass Transit In A Smart City: Rail Network Management At Singapore’S Land Transport Authority, Steven M. Miller, Thomas H. Davenport 2021 Singapore Management University

A Smarter Way To Manage Mass Transit In A Smart City: Rail Network Management At Singapore’S Land Transport Authority, Steven M. Miller, Thomas H. Davenport

Research Collection School Of Computing and Information Systems

There is no widely agreed upon definition of a supposed “Smart City.” Yet, when you see city employees — in this case city-state employees — working in what are obviously smarter ways, “you know it when you see it.” One such example of a smarter way to work in a smart city setting is the way that employees of the Land Transport Authority (LTA) in Singapore are using a new generation of data driven, AI-enabled support systems to manage the city’s urban rail network. We spoke to LTA officers Kong Wai, Ho (Director of Integrated Operations and Planning) and Chris Hooi ...

Racial Bias In Driver Yielding Behavior At Crosswalks, Kimberly Kahn, Peter Koonce, George Stern 2021 Portland State University

Racial Bias In Driver Yielding Behavior At Crosswalks, Kimberly Kahn, Peter Koonce, George Stern

TREC Friday Seminar Series

This seminar discusses how pedestrian race and gender can influence drivers’ behavior in interactions with pedestrians at crosswalks. Three speakers will present different lenses to look at this topic. Kimberly Barsamian Kahn, a researcher at Portland State University, will discuss research exploring how pedestrian race and gender influence drivers’ behavior in interactions with pedestrians at crosswalks. One dangerous potential point of conflict for pedestrians within the transportation system is interactions with drivers at crosswalks, and racial minorities are disproportionately represented in pedestrian fatalities. Research tested the hypothesis that drivers’ would demonstrate unequitable yielding based on pedestrians’ race and gender in ...


Numerical Investigations Of Virus Transport Aboard A Commuter Bus, Hamid Rahai, Jeremy Bonifacio 2021 California State University, Long Beach

Numerical Investigations Of Virus Transport Aboard A Commuter Bus, Hamid Rahai, Jeremy Bonifacio

Mineta Transportation Institute Publications

The authors performed unsteady numerical simulations of virus/particle transport released from a hypothetical passenger aboard a commuter bus. The bus model was sized according to a typical city bus used to transport passengers within the city of Long Beach in California. The simulations were performed for the bus in transit and when the bus was at a bus stop opening the middle doors for 30 seconds for passenger boarding and drop off. The infected passenger was sitting in an aisle seat in the middle of the bus, releasing 1267 particles (viruses)/min. The bus ventilation system released air from ...

Washington, DC is ranked second among cities in terms of highest public transit commuters in the United States, with approximately 9% of the working population using the Washington Metropolitan Area Transit Authority (WMATA) Metrobuses to commute. Deducing accurate travel times of these metrobuses is an important task for transit authorities to provide reliable service to its patrons. This study, using Artificial Neural Networks (ANN), developed prediction models for transit buses to assist decision-makers to improve service quality and patronage. For this study, we used six months of Automatic Vehicle Location (AVL) and Automatic Passenger Counting (APC) data for six Washington ...


Novel Method For Probabilistic Evaluation Of The Post-Earthquake Functionality Of A Bridge, Vesna Terzic, William Pasco 2021 California State University, Long Beach

Novel Method For Probabilistic Evaluation Of The Post-Earthquake Functionality Of A Bridge, Vesna Terzic, William Pasco

Mineta Transportation Institute Publications

While modern overpass bridges are safe against collapse, their functionality will likely be compromised in case of design-level or beyond design-level earthquake, which may generate excessive residual displacements of the bridge deck. Presently, there is no validated, quantitative approach for estimating the operational level of the bridge after an earthquake due to the difficulty of accurately simulating residual displacements. This research develops a novel method for probabilistic evaluation of the post-earthquake functionality state of the bridge; the approach is founded on an explicit evaluation of bridge residual displacements and associated traffic capacity by considering realistic traffic load scenarios.

This research ...
