Responses to Transit Homelessness

Abstract

Punitive responses restrict activities associated with homelessness through policing and can involve “hostile architecture,” such as seat dividers on bus benches. Outreach responses engage with unhoused transit riders to offer them referrals to services, shelter, and housing, often through collaboration with social service providers. These include centralised hubs of services, mobile outreach teams, transportation to shelters, and discounted fares. Proactive interventions include building shelters or housing on transit land and service planning with unhoused travellers in mind. While there are only a few evaluations of these strategies, the literature does indicate a growing awareness that removing unhoused riders from transit systems through punitive strategies addresses the challenge only momentarily, while external partnerships with social service agencies may offer more humane, effective, and sustainable solutions.

Homelessness in Transit Settings

Abstract

Many in homelessness seek shelter on transit vehicles, at transit stations, and in transit facilities. Surveys find that homelessness is prevalent on public transport, with especially high concentrations on larger systems and at central nodes. In regions with detailed counts, cold-climate cities and those with 24/7 service have reported over 60% of their unsheltered population found on transit vehicles or stops some years. However, data on homelessness on transit is patchwork at best. Almost all US transit agencies find homelessness a challenge, exacerbated by the COVID-19 pandemic. Those who shelter on transit are more likely to be homeless for at least a year and more structurally disadvantaged than their unhoused peers elsewhere. People experiencing homelessness do not just use transit for shelter: transit is the mode most commonly reported among studies of how unhoused people travel. Transit operators are increasingly recognizing that serving the unhoused population is part of their responsibility.

Transit Ambassadors

Abstract

A number of U.S. (public transport agencies (particularly rail systems) launched transit ambassador programmes in the 2010s and 2020s. Unarmed transit ambassadors serve as “eyes and ears” on transit vehicles and at stations. They help riders with customer service tasks, report incidents to other, more specialised staff, and broadly serve as figures of authority and vigilance where needed. Ambassadors orient riders; offer ticketing help; greet passengers and answer questions; and report crime, uncleanliness, and broken equipment. In emergency circumstances, ambassadors may render medical aid and respond to overdoses. They de-escalate altercations and serve as a first point of contact to people in homelessness. In the U.S., the nationwide racial reckoning after the 2020 murder of George Floyd by police prompted transit agencies to start or expand their civilian ambassador programmes. Very little research has studied transit ambassador programmes or evaluated their effectiveness.

StoryMap: Hiding Prejudice behind Parking

Publication Date

September 28, 2026

Abstract

Building a mosque requires careful planning to comply with zoning laws and manage community sentiment. Consider the Islamic Society of Santa Barbara (ISSB), the first mosque in this coastal California region. It took ISSB nearly 19 years to open after they purchased property in a rural part of the county. Why 19 years? A combination of city planning obstacles created the delay. First, the establishment of the town of Goleta in 2002 required ISSB to pull its original permit from Santa Barbara County and transfer it to Goleta, which, as a newly incorporated city, still lacked a functioning planning commission. Later, Goleta lost key staff members, delaying the project by three years. Most significantly, ISSB faced overwhelming opposition across 16 public hearings spanning nearly seven more years. Opponents at these hearings raised concerns about many issues, including the mosque’s design, the building’s potential impact on bird flight, and, most notably, where people who come to pray will park their cars. ISSB is not alone. According to the Institute for Social Policy and Understanding (ISPU), opposition to mosques is at an all-time high. In this context, it can be easy to focus on overt discrimination and zoning disputes. But it is just as important to show how benign and overlooked technical requirements – like parking – can become a cudgel to stop Muslim Americans from building places to gather and pray.

Transportation Labor Challenges for Gig Drivers

Abstract

Given the dynamic landscape surrounding the classification of workers in California, it is important to consider how the existing legal and regulatory environment may impact app-based gig drivers, including transportation network companies (TNCs, also known as ridehailing) and courier network services (CNS). Using a multi-method approach, we conducted a literature review (n = 41 sources), expert interviews (n = 8), and case study analysis (n = 7) between October 2022 to May 2024 to better understand how California’s gig drivers are impacted by state legislation and regulation (i.e., Assembly Bill 5, Proposition 22, and Senate Bill 1014). The expert interviews found that gig drivers are concerned with fair pay, benefits, labor classification, and transparency from the app-based platforms on issues related to punitive actions (i.e., deactivations). Drivers also raised concerns about California’s Clean Miles Standard (also known as SB 1014), which requires 90 % of vehicle miles traveled be electric by 2030, due to the financial costs associated with acquiring and operating electric vehicles (EVs) and limited public charging availability. The seven case studies examine gig labor policies from other states and countries (e.g., policies that may help enhance driver working conditions, platform regulation, and facilitate the EV transition). Together, these methods explore the tension between sustaining an app-based gig driving platform and providing fair compensation and working conditions for gig drivers. The study finds that state and/or local policies establishing minimum pay for drivers and policies enhancing transparency and appeal processes for driver deactivations could help improve working conditions for gig drivers. Various state agencies, such as the California Public Utilities Commission, could support gig drivers through incentives for the purchase of EVs and installation of EV charging near their homes and driving locations.

The Religion of Parking: How Land Use Planning Enables Anti-Muslim Prejudice

Publication Date

September 18, 2026

Author(s)

Abstract

In this article the research team considers a neglected injustice of parking policy: religious intolerance. Through qualitative interviews and a review of public hearing transcripts and official records, the research shows how residents and officials across the country use parking concerns to mask anti-Muslim prejudice and fight the construction of mosques. The team has isolated the role of religious discrimination quantitatively through a paired comparison of mosques and churches, finding newly proposed mosques are 16% to 18% more likely to experience opposition than newly proposed churches nearby. Further, in contrast to the mosques, parking concerns with the churches never made local news. By comparing parking ratios, the research team also demonstrates both mosques and churches typically provided more parking than codes required. These findings from the team’s mixed-methods study expand the transportation equity agenda to include religion and create space for planners to rethink how intolerance enters planning practice. Takeaway for practice: Planners should consider how zoning provisions that allow for regulatory discretion, such as parking requirements, open up avenues for prejudice. Although planners can shut down or disregard openly discriminatory comments at public hearings, it is hard for them to assess whether concerns over parking—and, by extension, other technical issues such as traffic and water—are genuine or are masks for underlying animus. Although federal laws like the Religious Land Use and Institutionalized Persons Act (RLUIPA) protect religious institutions from discrimination, mosque proponents and their attorneys are often reluctant to file lawsuits, particularly against agencies with discretionary authority, due to fear of costs and delays, or simply a desire to be friendly neighbors. Countering prejudice in land use planning therefore calls for removing procedural obstacles to development, giving city staff the authority to handle more permitting decisions ministerially, and eliminating parking requirements altogether.

Parking Policy Provides a Pretext for Anti-Muslim Discrimination

Publication Date

September 23, 2026

Author(s)

Abstract

Building a mosque in the US gives rise to opposition. Sometimes, opponents overtly depict Muslims as foreigners threatening American values. In other cases, new mosques are stalled for years or stopped altogether because of concerns about parking: Local officials and residents demand that mosques build more spaces, conduct additional costly parking studies, or attend further public hearings about parking.
Mosques are far from the only type of proposed development to face parking-related opposition. This study isolated the role of religious prejudice by analyzing the opposition faced by 107 newly constructed American mosques, comparing each one to a nearby church built around the same time. Public records of city council hearings were examined and representatives from a sample of the mosques were invited to share their experiences on whether or how parking came up and the impacts of parking-related opposition.

Examining Racial/Ethnic and Socioeconomic Disparities in Access to California’s Electric Vehicle Charging Infrastructure

Abstract

Equitable access to electric vehicle charging infrastructure is critical to ensuring a rapid, widespread, and inclusive transition to clean transportation. Here, this team evaluates disparities in electric vehicle charging access across California by race, ethnicity, income, housing status, and environmental vulnerability. They uses spatially granular synthetic population data and develop competition-adjusted access metrics for Level 2 and direct current fast chargers using isochrone analysis. They show clear disparities: Black and Hispanic Californians, especially those in majority Black and Hispanic (respectively) neighborhoods, have significantly lower access to charging than white residents. These gaps are wider in dense urban areas and among renters and people living in multifamily housing. Achieving a just transition requires that public and private investment in charging infrastructure account for racial/ethnic and housing equity. Robust analytic methods are therefore essential for effective planning and policy design.

Abstract

This white paper examines the successes and failures of road pricing strategies in California and the United States, with implications for congestion pricing across California. It evaluates nine case studies spanning feasibility studies, operational HOT lane programs, and the country’s first large-scale cordon pricing zone. The research team addresses the conditions that favor pricing, barriers, outcomes, and how costs and benefits are distributed using case studies in Los Angeles, San Diego, San Francisco, San Mateo County, Alameda County, New York City, and Northern Virginia. The research finds that successful pricing programs have sustained political champions, state enabling legislation, and benefits visible to identifiable users. Revenue allocation, not toll structure, is the primary determinant of whether pricing is regressive or progressive. No pricing program reviewed was repealed after implementation. The research team concludes that advancing road pricing in California will require clear state leadership and supportive coalitions.

Equity and Road Pricing: Fairness and Affordability

Abstract

This white paper reconsiders the equity of road pricing by distinguishing between fairness and affordability—two concepts that are otherwise often conflated. A fair price assigns costs in proportion to the burdens a user imposes on others; an affordable price is one that users can pay without hardship. While both are important, these are distinct objectives, and treating them as interchangeable can obscure judgments about whether pricing is morally or ethically correct. Applying this framework suggests congestion pricing is more equitable than flat VMT charges because it better aligns payments with the social costs of driving. While congestion pricing may raise affordability concerns for some users, these concerns can be addressed through targeted redistribution of toll revenues. By contrast, unpriced roads and poorly targeted charges allow drivers to impose substantial external costs on others, undermining fairness even as they appear more affordable.
