Spatio-Temporal Analysis Of The Roadside Transportation Related Air Quality (Startraq) And Neighborhood Characterization, Jaymin Kwon, Yushin Ahn, Steve Chung

Mineta Transportation Institute Publications

To promote active transportation modes (such as bike ride and walking), and to create safer communities for easier access to transit, it is essential to provide consolidated data-driven transportation information to the public. The relevant and timely information from data facilitates the improvement of decision-making processes for the establishment of public policy and urban planning for sustainable growth, and for promoting public health in the region. For the characterization of the spatial variation of transportation-emitted air pollution in the Fresno/Clovis neighborhood in California, various species of particulate matters emitted from traffic sources were measured using real-time monitors and GPS ...


Gaps And Opportunities In Accessibility Policy For Autonomous Vehicles, William Riggs, Anurag Pande 2021 University of San Francisco

Gaps And Opportunities In Accessibility Policy For Autonomous Vehicles, William Riggs, Anurag Pande

Mineta Transportation Institute Publications

Nearly 1 in 5 people in the US have a disability (more than 57 million) (U.S. Census Bureau), and people with disabilities use the automobile as a travel mode at significantly lower rates than people without disabilities (Bureau of Transportation Statistics). For example, people aged 18 to 64 with disabilities make 28% fewer trips per day (2.6 v. 3.6 trips) on average than people without disabilities. The disparity is even more significant for non-workers. These statistics highlight the notable technological, design, and policy failings in today’s transportation system - that disabled individuals have considerable suppressed demand for ...

How Do Environmental Factors Affect Drivers’ Gaze And Head Movements?, Arash Tavakoli, Vahid Balali, Arsalan Heydarian

Mineta Transportation Institute Publications

Studies have shown that environmental factors affect driving behaviors. For instance, weather conditions and the presence of a passenger have been shown to significantly affect the speed of the driver. As one of the important measures of driving behavior is the gaze and head movements of the driver, such metrics can be potentially used towards understanding the effects of environmental factors on the driver’s behavior in real-time. In this study, using a naturalistic study platform, videos have been collected from six participants for more than four weeks of a fully naturalistic driving scenario. The videos of both the participants ...

Webinar: The Impact Of Ride Hail Services On The Accessibility Of Nonprofit Services, Dyana Mason 2021 University of Oregon

Webinar: The Impact Of Ride Hail Services On The Accessibility Of Nonprofit Services, Dyana Mason

TREC Webinar Series

Nonprofit organizations are responsible for providing human services across the United States, often in partnership with government agencies. In this work, they address some of the most pressing social issues – including homelessness, poverty, health care and education. While many of these organizations consider location and accessibility crucial to supporting their clients – often locating services near bus or train stops, for example – little is known about the impact of new technologies, including ride hail services (also called Transportation Network Companies, or TNCs) like Lyft and Uber, on nonprofit accessibility. Do these services help fill gaps in client needs? How are nonprofit ...

Steps To Supplement Park-And-Ride Public Transit Access With Ride-And-Ride Shuttles, John S. Niles, J. M. Pogodzinski

Mineta Transportation Institute Publications

Public transit ridership in California declined in the five years before the pandemic of 2020–21 and dropped significantly further after the pandemic began. A sharp downward step in the level of transit boarding occurred after February 2020, and continues to the date of this report as a result of the public-health guidance on social distancing, expanded work-at-home, and a travel mode shift from public transit to private cars. A critical issue has come to the foreground of public transportation policy, namely, how to increase the quality and geographic reach of transit service to better serve the essential trips of ...

Mineta Transportation Institute Publications

Trucks serve significant amount of freight tonnage and are more susceptible to complex interactions with other vehicles in a traffic stream. While traffic congestion continues to be a significant ‘highway’ problem, delays in truck travel result in loss of revenue to the trucking companies. There is a significant research on the traffic congestion mitigation, but a very few studies focused on data exclusive to trucks. This research is aimed at a regional-level analysis of truck travel time data to identify roads for improving mobility and reducing congestion for truck traffic. The objectives of the research are to compute and evaluate ...

TREC Webinar Series

This presentation introduces an innovative spatiotemporal analytical framework and web-based visualization platform developed by researchers at the University of Utah to assist transit agencies in identifying optimal deployment strategies for a battery-electric bus (BEB) system by using a combination of mathematical programming methods, GIS-based analysis, and multi-objective optimization techniques. The framework allows transit agencies to optimally phase in BEB infrastructure and deploy the BEB system in a way that can minimize the capital and operational cost of the BEB system while maximizing its environmental benefits (i.e., emission reduction).


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 ...


Do Multi-Use-Path Accessibility And The Clustering Effect Play A Role In Residents' Choice Of Walking And Cycling?, Chih-Hao Wang, Na Chen 2021 California State University, Fresno

Do Multi-Use-Path Accessibility And The Clustering Effect Play A Role In Residents' Choice Of Walking And Cycling?, Chih-Hao Wang, Na Chen

Mineta Transportation Institute Publications

The transportation studies literature recognizes the relationship between accessibility and active travel. However, there is limited research on the specific impact of walking and cycling accessibility to multi-use paths on active travel behavior. Combined with the culture of automobile dependency in the US, this knowledge gap has been making it difficult for policy-makers to encourage walking and cycling mode choices, highlighting the need to promote a walking and cycling culture in cities. In this case, a clustering effect (“you bike, I bike”) can be used as leverage to initiate such a trend. This project contributes to the literature as one ...

Robotic Parking Technology For Congestion Mitigation And Air Quality Control Around Park & Rides, Mahdi Yoozbashizadeh, Forouzan Golshani

Mineta Transportation Institute Publications

A lack or limited availability for parking may have multiple consequences, not the least of which is driver frustration, congestion, and air pollution. However, there is a greater problem that is not widely recognized by the public, namely the negative effect on the use of transit systems due to insufficient parking spaces close to key transit stations. Automated parking management systems, which have been successfully deployed in several European and Japanese cities, can manage parking needs at transit stations more effectively than other alternatives. Numerous studies have confirmed that quick and convenient automobile access to park-and-ride lots can be essential ...

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

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

Master of Urban and Regional Planning Workshop Projects

In partnership with the Portland Bureau of Planning and Sustainability (BPS), we sought to better understand how off-street parking space could accommodate economic activity in East Portland, the city’s most economically and racially diverse neighborhood. We focused on two different neighborhoods based on equity considerations and interest: the Rosewood and the Jade Districts. The goal was to better understand these areas with granularity but also to juxtapose them looking for similarities and differences that could guide our recommendations for using parking spaces and serving the community. This project was exploratory in nature. Our research questions and resulting deliverables were ...


Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub 2021 Portland State University

Webinar: Eliminating Cash Options For Public Transit Fares: Costs, Benefits And Equity Impacts, Aaron Golub

TREC Webinar Series

Many transit agencies plan to automate their fare collection and limit the use of cash, with the goals of improving boarding and data collection while lowering operating costs. Yet about 10% of adults in the United States lack a bank account or credit card, and many either rely on restrictive cell-phone data plans or don’t have access to internet or a smartphone. This webinar will present part of a larger research project exploring these issues in the cities of Denver, Colorado, and Eugene and Portland–Gresham, Oregon. In this part, we explore the tradeoffs between reducing cash acceptance, ridership ...


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 ...
