In 2018 electric powered shared scooters and stationless electric bikeshare proliferated throughout the United States. Many cities have begun to experiment with new permitting systems and regulations for these vehicles. To date, there is scant academic literature on how well scooter and stationless bikeshare permits have helped cities achieve their transit, sustainability, and equity goals. San Francisco was one of the first cities in the United States to create permit systems for stationless bikeshare and scooter companies. This research evaluates scooters and stationless bikeshare use as a first/last mile transit option, reductions in vehicle miles traveled (VMT), and equity of utilization. The author evaluates these systems using a mixed methods approach and primary data collected by the San Francisco Municipal Transportation Agency (SFMTA) as part of its pilot permit programs. Results indicate that the two travel modes substantially support transit usage, both by connecting riders to transit and by replacing automobile trips. Shared e-bikes reduce VMT significantly more than scooters by replacing more and longer auto trips. Scooters are more likely to reduce VMT by connecting riders to transit. Rider demographics for both travel modes do not demonstrate improved equitable utilization as compared to traditional, personally owned bikes at this time.

Los Angeles County Metropolitan Transportation Authority (LA Metro) planning staff, working alongside engineers from the Los Angeles Department of Transportation (LADOT) seek to make improvements to the Metro G Line (Orange) busway to address a number of operational problems with the popular line. The Metro G Line is the backbone of transit in the San Fernando Valley, serving more than 22,000 pre-COVID-19 pandemic weekday boardings. Part of the problem for public transit in a chronically traffic congested place like Los Angeles is that buses typically have to compete for road space with private automobiles. As a result, buses get stuck in traffic. Light rail vehicles, when travelling on surface streets with cars, get stuck in traffic as well. The G line busway thus has a significant advantage, as it runs on its own dedicated route. Efforts to further separate the G line from nearby traffic, such as grade separated over- and under-passes or railroad-style gate arms at street crossings, will require complex planning and take considerable time and resources to implement. However, speeding up the G line with current infrastructure is possible by improving transit signal priority (TSP). TSP prioritizes a direction along a roadway by extending green time at signals so priority vehicles (in this case buses) can pass through an intersection without stopping.This report explores the current signal regime along the G line alignment, some of the history of the TSP system, and draws on case studies to develop applicable lessons to the Metro G line.

The Every Student Succeeds Act (2015) gave foster youth additional legal protections in school, including the right to transportation and the right to remain at their school despite any moves, similar to protections already in place for students experiencing homelessness and students with disabilities. Californiaís compliance with this mandate was relatively more difficult than other statesí, as less than ten percent of students in California travel by school bus, compared with 35 percent nationally. Thus, California schools could not simply tap into their existing services to provide transportation for foster youth. Ridehailing offers a solution to this gap. HopSkipDrive, a ridehailing company designed to transport children, engages in contracts with school districts and county governments to provide school transportation for these vulnerable student populations. In 2018ñ2019, HopSkipDrive provided 32,796 trips to school in Los Angeles County, with massive time savings over the logical alterative: transit. Using Googleís Directions API, I determine that HopSkipDrive offers time savings of nearly 70 percent compared with the same trips simulated on transit. HopSkipDriveís trips average 28 minutes in duration, yet on transit only 30 percent would have taken less than 45 minutes. This is despite 90 percent of all origins and destinations being located within a half-mile of a transit stop. This service has important social equity implications beyond just time savings offered to vulnerable student populations, as HopSkipDrive contract trips tend to originate in neighborhoods with high percentages of low-income households and people of color.

There is growing interest in the use of hydrogen as a transportation fuel but the environmental benefits of using hydrogen depend critically on how it is produced and distributed. Leading alternatives to using fossil natural gas to make hydrogen through the conventional method of steam methane reforming include using electrolyzers to split water into hydrogen and oxygen, and the use of biogas as an alternative feedstock to fossil natural gas. This report examines the latest carbon intensity (CI) estimates for these and various other hydrogen production processes, adding important nuances to the general “colors of hydrogen” scheme that has been used in recent years. CI values for hydrogen production can vary widely both within and across hydrogen production pathways. The lowest CI pathways use biomass or biogas as a feedstock, and solar or wind power. The report also analyses jobs creation from new hydrogen production facilities and shows that these benefits can be significant for large-scale facilities based on either future biomass/biogas-to-hydrogen or solar-hydrogen production technologies. Recommendations include setting stricter goals for the state’s Low Carbon Fuel Standard (LCFS) program to continue to reduce the carbon footprint of California’s transportation fuels.

In the last ten years transit use in Southern California has fallen significantly. This report investigates that falling transit use. We define Southern California as the six counties that participate in the Southern California Association of Governments (SCAG) – Los Angeles, Orange, Riverside, San Bernardino, Ventura and Imperial. We examine patterns of transit service and patronage over time and across the region, and consider an array of explanations for falling transit use: declining transit service levels, eroding transit service quality, rising fares, falling fuel prices, the growth of Lyft and Uber, the migration of frequent transit users to outlying neighborhoods with less transit service, and rising vehicle ownership. While all of these factors probably play some role, we conclude that the most significant factor is increased motor vehicle access, particularly among low-income households that have traditionally supplied the region with its most frequent and reliable transit users.

Public investment in transit increased following the Great Recession, yet transit use nationally mostly fell, even prior to the 2020 pandemic. We investigate this troubling disjuncture by comparing transit ridership trends during the 2010s in two of America’s largest regions: Greater Los Angeles and the San Francisco Bay Area. While both California regions lost transit riders, we see substantial differences in the scale, timing, geography, and modes of these declines. In the LA area, ridership fell longer and further, spread more across routes, times, and sub-regions and concentrated on the region’s dominant operator. In both regions, increasing auto access appears to have played a central role, albeit in different ways. Greater LA saw increased automobile ownership, particularly among high-propensity transit riders. In the Bay Area, as jobs and housing have dispersed, ridehail services like Lyft and Uber may have eroded non-commute transit use.

COVID-19 altered travel patterns in the U.S. Studies have analyzed the effect of the pandemic on travel mode, including working from home, but few have focused on automobile ownership—a relationship with potentially long-term consequences for accessibility, household budgets and debt, and policy efforts to meet climate goals.To understand the association between the pandemic and automobile ownership, we rely on a unique credit panel dataset from Experian and examine three different automobile loan-related outcome measures: annualized growth rate of new automobile loan balances, average new loan size, and the number of new loans. We focus specifically on changes across loans in neighborhoods by race/ethnicity, hypothesizing larger increases in automobile debt in Black and Latino/a neighborhoods, where workers are less likely to be able to telework. The annualized growth rate of new automobile loans increased during the pandemic across all neighborhoods by race/ethnicity, increasing most rapidly in Latino/a neighborhoods. Controlling for other factors, loan size increased similarly across neighborhoods by race/ethnicity. The increase in automobile lending in Latino/a neighborhoods, therefore, likely was explained by a significant uptick in the number of new loans.The growth in automobile lending during the pandemic was potentially prompted by pandemic-induced changes in the need for automobiles and facilitated by an expanded social safety net. As the pandemic and its various forms of public financial assistance recede, the findings underscore the importance of ongoing assistance in enabling automobile ownership or shared access among households with limited means whose livelihoods depend on the access that vehicles provide.

More than 500,000 people experience homelessness in the United States, and many turn to transit vehicles, stops, and stations for shelter. We present findings from a survey of 115 U.S. and Canadian transit operators that inquired about homelessness on transit systems. We find that homelessness is broadly present, though more concentrated on central hotspots, and worsened during the pandemic. In response, transit agencies often initiate a combination of punitive and outreach strategies. Based on our findings, we argue for better data collection, establishment of policies and protocols, engagement in outreach strategies, and partnering with service providers.
