Is Parking Cash-Out Worth It? Comparing Cost-Effectiveness And Climate And Equity Benefits In The Bay Area And South Coast Air Quality Management Districts, Fynnwin Prager, Tianjun Lu, Ashley Membere, Parveen Chhetri

Mineta Transportation Institute

This research explores the potential impacts of California parking cash-out policy changes on the Bay Area and LA County. Parking cash-out—a California law since 1992—requires that certain qualifying employers who subsidize employee parking offer employees the option to give up their parking space and receive cash instead. Studies show parking cash-out substantially reduces VMT and emissions, yet enforcement remains voluntary. Current policy covers few firms (<1%) and employees (around 11%) in the study regions. Policy reform to include companies with 20+ employees could increase this to 18%. Our experimental-design survey (n=963) explores behavioral changes in response to multiple policy variables and finds that 76.9% of employees would accept cash-out if offered, and that participants who had to pay the market rate for parking and were full-time commuters were more likely to switch to using public transportation at lower cash minimums. VMT related to employees covered by parking cash-out are substantial (5.6 million in the Bay Area; 5.7 million in LA County), and account for a combined 6,593 daily tons of GHG. As even limited adoption could have significant environmental benefits, parking cash-out would be a more cost-effective approach to reducing VMT than traditional TDM programs such as trip-reduction programs, workplace parking taxation, or transit subsidies and road diets, though further evidence on the direct influence of parking cash-out on commuter behavior is needed.

Streets Are For People! Livable Streets 2.0 And Five Decades Of The Conflict, Power And Promise Of Our Streets, Bruce Appleyard

PSU Transportation Seminars

Streets constitute the majority of our urban public spaces, yet we struggle everyday with how they should be designed and operated for travel, safety, and livability. In 1969, when Dr. Bruce Appleyard was 4 years old, he was hit by a car and nearly killed. Around that time his father, Donald Appleyard, started work on what would become Livable Streets, published in 1981 – a ground-breaking and seminal work, the product of more than a decade of rigorous research and thoughtful analysis that would uncover the ill effects of traffic and laying out the seminal arguments that streets are for …

Oregon In Motion: Shaping Communities Through State Transportation Legislation, Cassie Wilson

PSU Transportation Seminars

About every eight years, the Oregon state legislature passes a large state transportation funding package. Transportation funding packages in Oregon have historically included funding mechanisms such as the gas tax, program areas such as Safe Routes to School, projects such as freeway widenings, and transparency and accountability measures such as establishing new reporting requirements and advisory committees. The way this legislation is developed and who has a seat at the table highly influences package contents and the public and political support needed for its passage. In this presentation, I will provide highlights from my recently published report, Oregon in Motion …

Does California High-Speed Rail Promote Accessibility For Station Cities?: Case Study Of Fresno And Merced, Chih-Hao Wang, Na Chen

Mineta Transportation Institute

California High-Speed Rail (CHSR) will largely change transportation cost across the state after it starts operating. Past studies show that only Fresno and Merced among station cities in the Central Valley would attract more future activities with the CHSR. The establishment of active CHSR also implies a new daily living sphere for all the station cities, and, therefore, accessibility to work and residential amenities should be reviewed to inform planners of future land-use and transportation developments. A research framework has been developed better to understand the impact of CHSR on job and amenity accessibility by driving, transit, and walking in …

Shifting Gears: Toward A New Way Of Thinking About Transportation, Susan Handy

PSU Transportation Seminars

The transportation system in the U.S. has been shaped by a core set of ideas that are embedded in professional practice. These ideas – freedom, speed, mobility, vehicles, capacity, hierarchy, separation, control, and technology – have produced a system in which most people are dependent on driving, with all the negative consequences that entails. Shifting to a system that offers people choices about their daily travel requires a shift in thinking on the part of the transportation profession. In this talk, I take a critical look at the way of thinking that, for the last century, has shaped our transportation …

Webinar: Marginalized Populations’ Access To Transit, Marisa Zapata

TREC Webinar Series

How do people with intersecting marginal identities experience social exclusion as they travel via mass transit? To answer this question, PSU researchers employed a qualitative method less common in transportation studies: photovoice. Researchers asked participants to describe the factors that shape their travel behavior and provide photographic data of their experiences. Then, they conducted in-depth video interviews to gain further depth and clarity regarding the visual data.

Containerization Of Seafarers In The International Shipping Industry: Contemporary Seamanship, Maritime Social Infrastructures, And Mobility Politics Of Global Logistics, Liang Wu

Dissertations, Theses, and Capstone Projects

This dissertation discusses the mobility politics of container shipping and argues that technological development, political-economic order, and social infrastructure co-produce one another. Containerization, the use of standardized containers to carry cargo across modes of transportation that is said to have revolutionized and globalized international trade since the late 1950s, has served to expand and extend the power of international coalitions of states and corporations to control the movements of commodities (shipments) and labor (seafarers). The advent and development of containerization was driven by a sociotechnical imaginary and international social contract of seamless shipping and cargo flows. In practice, this liberal, …

What Drives Housing Choices Of Refugees And Immigrants?, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens, Yasmin Al-Zubi, Farah Naz

TREC Project Briefs

When newcomers to the US initially settle, if their chosen location does not meet their expectations or needs, that often propels them to relocate. To determine what helps drive those transition decisions, the researchers interviewed people if they fulfilled one of these requirements:

• They were members of the Dallas County community who were planning to move in the next five years.

• They had recently (within the past five years) moved from their initial residence following their arrival in Dallas County.
• They also had to be immigrants to or refugees in the US who were at least eighteen years old. Out …

Incomplete Streets, Michael Lewyn

Scholarly Works

Over 1700 complete streets policies have been adopted by state and local government; these policies typically provide that streets shall be designed to benefit all users, not just motorists. This article analyzes some complete streets policies, and concludes that even above-average policies are often too vague and underfunded to significantly change the status quo. The article suggests a variety of reforms that might make complete streets policies more effective.

Housing Choice, Transportation Equity, And Access To Opportunities In Refugee And Immigrant Communities, Diane Mitschke, Anne Nordberg, Stephen Mattingly, Katherine Kitchens

TREC Final Reports

Mobility directly impacts access to opportunities for all protected classes; however, transportation planning and public transit agencies and housing authorities rarely coordinate affordable housing and the transportation system planning decisions. This lack of coordination often leads to mismatches between access to opportunities and affordable housing. Safe access to employment, quality schools, and healthcare represent a few of the many factors that may influence housing choice. For most households with budget constraints, all of these factors may not be achievable. While existing research documents the mismatch between affordable housing and access to opportunities, the role that mobility plays in residential selection …

Fields, Courtney Cronley, Stephen Mattingly, Nicole Iroz-Elardo, David Levine, Nithisha Gudipati, Cristine Highfill, Mary Kris Stringfelllow, Anna O'Dell, Rebecca Cole, Melody Huslage

TREC Final Reports

Our interdisciplinary team refined an app prototype, MyAmble, to gather data related to quantity of transportation disadvantage and latent demand, and to identify psycho-social-economic corollaries. MyAmble utilizes a traditional travel diary format but expands the type of trips measured to include 1) completed trips, 2) missed trips, and 3) latent travel demand. The app also measures the real-time perceived impact of transportation behaviors (realized and latent) on participants’ physical health, mental health, social engagement, and employment/academics. Finally, the app has a text-messaging feature, Travel Buddy, that is used to increase participant engagement and retention over longitudinal data collection. The project …

An Integrated Framework For Establishing Long-Term Transportation Management Strategies Promoting Sustainable Urban Growth, M Imtiaz Rahman

Graduate Theses, Dissertations, and Problem Reports (ETD)

Urban land areas are experiencing a more rapid expansion compared to their population growth on a global scale. This phenomenon, known as urban sprawl, is characterized by low-density development in the outskirts of cities. This unplanned urban growth leads to changing urban transportation patterns, posing a threat to sustainable development. In response, government agencies implement growth management practices, with transportation management strategies playing a crucial role in achieving sustainable urban growth. However, developing effective growth management strategies is difficult because of several challenges, including limited understanding of the key influencing factors, the complex interdependencies among these factors, and the uncertainties …

Scooting To A Brighter Tomorrow: Shared E-Scooters And Their Use In Lincoln, Nebraska, Tanner J. Hiemer

Community and Regional Planning Program: Theses

As a recent addition to our transportation systems, shared e-scooters have the potential to improve how people travel in the urban environment. While there is a lot to be hopeful about, the relative novelty of e-scooters calls for closer examination of how they interact with the built environment and other modes of transportation. Additionally, the equity of shared e-scooters must be at the forefront of discussion when considering their utility in the future. Given their flexibility in use, e-scooters could fill spatial gaps in transportation systems and provide improved mobility to those who are most transportation disadvantaged. This research aims …
