Reviving public transit ridership to downtowns and employment centers: Case Studies of San Francisco, San Jose, Oakland, Berkeley, and Walnut Creek

Abstract

This paper examines transit ridership and its role in downtowns in five San Francisco Bay Area cities pre-and post-COVID. The research analyzes transit ridership data from 2019 and 2022-24, review transit agency responses to COVID’s consequences, and examine the plans and proposals for downtowns adopted by the cities and those developed by business improvement districts (BIDs). The research draws upon focus groups that the research held with transit users and interviews that were conducted with key stakeholders to gain additional information and insights. The research finds that trips to, from and within our five case study downtowns account for a significant share of overall regional transit ridership, a finding that underscores downtown transit’s importance to state and regional goals for greenhouse gas reduction, pollution abatement, economic prosperity, and equity and inclusion. For the five downtowns, transit ridership is on a path to recovery but as of early 2024 was still falling short of pre-COVID levels, leaving transit agencies facing financial shortfalls despite service adjustments and other cost-cutting measures. The downtowns with concentrations of employment that generally depend on face to face contact (healthcare, education), are faring better than those where working remotely suffices and this appears to be largely independent of the workers’ income levels. For general offices, the longer transit trips that rail services provide have not recovered as quickly as shorter bus trips. Downtown plans for the five cities assume transit will be available and used, but have not been updated to deal with changed conditions. The case studies’ city officials and business leaders have proposed additional housing, sports events, and frequent festivals and farmers markets as ways to invigorate downtowns. While these strategies could lead to more transit use, they are unlikely to make up for the losses in office worker transit use, a consequence of increased working at home or in a hybrid home-office mode. Since recovery to previous levels may take several more years, finding ways to support transit in the meantime will be important.

Customer-Oriented Open Data for Accessible Transit: A Case Study in Contra Costa County

Abstract

This report presents a set of proposed open data specifications for the development of an Operational Data Portal (ODP) to support customer-oriented “smart” apps for travelers with special needs, particularly seniors and people with disabilities, in Contra Costa County. The ODP would aggregate and organize data from various mobility service providers, individual riders, and community organizations to be accessed by software developers of digital trip planners, trip booking and scheduling services, passenger feedback mechanisms, and service performance evaluation tools. The report concludes that the establishment of an open data platform along with supporting applications will improve the rider experience and facilitate operating efficiency and coordination among accessible transit providers. It recommends further research to align the proposed data specifications with emerging transportation data standards, enhance the integration of unstructured data, and develop inclusive systems for customers with limited access to smart devices.

Improving Evacuation and Resilience Strategies for Older Adults During and After Wildfires: A Systemic Review

Abstract

Background and Aim: Natural hazard-related disasters such as wildfires, hurricanes, earthquakes, and floods pose significant risks to older adults, individuals with disabilities, and those with chronic health conditions. Transportation-related challenges during and after evacuation can severely impact their safety, mobility, and recovery. This scoping review examines the current evidence to identify research gaps and inform strategies to improve evacuation outcomes and long-term resilience for these at-risk groups. The STEPS framework (Spatial, Temporal, Economic, Physiological, Social) was applied to guide the analysis and interpretation of findings. Methods: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines and searched five databases, including PubMed, APA PsycINFO, CINAHL Complete, EMBASE, and Web of Science for primary studies on transportation and disaster evacuation among vulnerable populations. Results: Twenty studies were included. Four key areas of concern were identified: (1) immediate transportation barriers during evacuation, (2) prolonged transportation disruptions post-disaster, (3) anticipated logistical challenges in future evacuation planning, and (4) inconsistent and inaccessible communication of transportation-related information during emergencies. These challenges intersected with all five STEPS dimensions. Conclusions: Transportation barriers remain a persistent and under-addressed risk factor in disaster contexts for vulnerable groups. The STEPS framework helped reveal the multidimensional nature of these issues, emphasizing the need for integrated planning, assistive transport options, inclusive communication systems, and stronger public–private coordination. Future research should focus on collecting disaggregated data, evaluating interventions, and supporting inclusive policy reforms tailored to each type of disaster.

Wildfire Recovery and Resilience Strategies for Resource-Constrained and Vulnerable Communities

Abstract

Wildfires disproportionately impact vulnerable communities, such as low-income families, older adults, people with disabilities, and rural residents. Wildfires not only cause direct destruction, but also intensify existing social inequities (Davies et al., 2018). The primary challenges these groups face lie in inadequate transportation resources to carry out evacuations, non-resilient infrastructure, and inequitable allocations of recovery resources. This brief synthesizes news reports, academic research, and practical case studies and recommends three priority strategies to support efforts to recover from the recent wildfires in Los Angeles County: 1) developing an inclusive evacuation system, 2) allocating resources for community recovery in a fair and equitable manner, and 3) building resilient community transportation systems for the future. These strategies can reduce social inequalities in disaster response and recovery.

Transportation Challenges of Low-Income Households with Children: A Case Study in South Los Angeles

Publication Date

February 26, 2026

Abstract

Low-income households commonly lack access to quality and affordable transportation options, impeding their access to opportunities. Low-income households with children face additional challenges. The research draws on data from thirty-nine in-depth interviews to examine the effect of children on the travel behavior and experience of low-income adults. The research finds that low-income households with children experience increased financial and temporal burdens related to travel. These unique and complex challenges result in fewer socioeconomic opportunities and financial resources and reduced time for non-travel activities. The findings underscore the importance of programs and policies to develop a multimodal, affordable transportation safety net.

Planning Light- and Heavy-Duty ZEV Infrastructure for a More Resilient Fueling Network in California

Abstract

To meet goals for air quality improvement and greenhouse gas reduction, California aims to expand both light-duty and heavy-duty zero-emission vehicles (ZEVs). To support these aims, the State has set targets for the number of electric charging and hydrogen fueling stations, but deployment is falling short of these targets. For example, there were only 50 hydrogen stations and just over 200,000 chargers as of September 2025, as compared to the goals for this year, set in 2018, of 200 hydrogen stations and 250,000 electric vehicle chargers. Building a large, reliable, equitable network in a short time presents challenges of scale, reliability, and resiliency. One possible way to address these challenges is to combine light-and heavy-duty vehicle charging and fueling infrastructure, given the overlap of these vehicles’ travel patterns and of the respective charging and fueling technologies used. The research investigates how this strategy could support robust charging and refueling networks for projected ZEV growth. To that end, the research also developed a “conservative” and an “optimistic” scenario to simulate charging and hydrogen fueling station deployment across California for 2025, 2035, and 2045.

Autonomous Trucking: Workforce-Safety Dynamics and Policy Implications

Abstract

Autonomous trucks raise complex and interconnected questions about public safety and the future of labor. This white paper examines this safety and workforce connection through a review of multidisciplinary literature and findings from expert interviews to evaluate three automated trucking pathways: driverless trucks, truck platooning, and automated driving assistance systems (ADAS). A central finding is that human autonomy teams will remain integral across all three trajectories. Humans will co-design, test, supervise, and maintain these systems, playing enduring roles in pre-drive, front-line (including in-vehicle), and remote (off-vehicle) settings. These roles represent durable labor categories whose scope, skill requirements, and job quality will be shaped by regulatory design choices that also influence public safety outcomes. This paper finds that partial automation is likely to expand more rapidly than fully driverless operations, creating near-term opportunities to leverage ADAS technologies to improve safety and workforce retention. Investments in retraining and education can help workers transition into emerging roles, while advances in ADAS and ADS safety standards should explicitly address risks to both workers and the public. Greater coordination across government, labor, and industry will also be essential to implement these strategies and ensure that autonomous trucking supports higher-quality jobs and leads to safer, more resilient goods movement systems.

Making Workplace Charging Work: What Employees Value in Managed and Bidirectional Programs

Abstract

California’s climate goals increasingly depend on shifting electric vehicle (EV) charging to midday, when clean, low-cost solar energy is most abundant. Doing so could help utilities avoid having to curtail solar energy and prevent reliability-driven infrastructure upgrades that would raise rates for all customers. Workplace charging programs are well positioned to support this shift, as many vehicles remain parked during daylight hours. However, workplace charging presents a cost dilemma. Since home charging is typically less expensive, employees may be reluctant to use workplace chargers unless prices are heavily discounted—yet offering free or low-cost charging extends the time it takes for employers to recoup infrastructure investments.

Will California Lose Thousands of Affordable Homes Near Transit?

Abstract

California faces the loss of thousands of affordable rental units in the coming decade as affordability restrictions— known as covenants—expire. These agreements, signed between housing developers and government agencies, typically last 15 to 30 years and require that units be rented at below-market rates. When covenants expire, owners can convert units to market-rate housing, often displacing lower-income families.

In Southern California alone, over 17,000 affordable units are at risk of conversion, and nearly 70% of these units are located near high-quality transit. If the owners of these properties do not enter into new covenants, these units will be placed on the open market, likely leading to the displacement of lower-income residents to the urban outskirts, resulting in longer commutes and reduced access to reliable transit. To better understand the risk of losing affordable units, this brief analyzed historic data on affordable housing conversion and identified key factors that influence whether at-risk properties are preserved or lost.

Abstract

Transit-oriented development (TOD) is a strategy that promotes building housing, shops, offices, and other destinations near public transit stations. TOD is compact and walkable, supports public transit use, reduces car dependency, and can help lower greenhouse gas emissions by decreasing the number of miles people drive. California has adopted many policies in recent years– at the state, regional, and local levels– to encourage TOD as part of its broader climate and housing goals. At the same time, the state faces a housing affordability crisis. In the past seven years, state lawmakers have passed more than 100 bills aimed at increasing housing production, particularly in areas near public transit.
