Transit use is on the decline in many American cities. Research has shown that concerns about transit safety may influence travel behavior and transit use, and that women are particularly fearful about victimization while travelling. Studies have also shown that women are also very concerned about one type of crime — sexual harassment — which often goes unreported, and thus remains largely invisible to transit operators.The research team will survey college students in 16 cities in six continents to examine their patterns of mobility and transit, with an emphasis on their feelings of safety on public transit and other transportation modes, experiences of sexual harassment, and other types of crime and victimization on public transport and other transportation modes. The results of the survey will establish the extent to which fear regarding their safety affects college students’ transit ridership, and the research team will examine how survey responses may vary because of the students’ sociodemographic characteristics.

Every regular school day, LAUSD operates over 14,000 hours of service using 1,307 school buses to serve over 38,000 students, who attend more than 300 schools in more than 30 subdistricts, on 1,669 routes over a service area of about 750 square miles. Bus contractors own and operate another 700 school buses to provide service for LAUSD. LAUSD also provides service for midday, athletic events, after-school programs, and on weekends. The buses are subject to traffic conditions — operating both during peak traffic times and during non-peak traffic times — and to changing enrollment patterns. LA’s very large geographic area, as compared to other US cities, makes the problem particularly acute (and also scientifically interesting).The project team seeks to help the Student Transportation Operation of the LAUSD better match its capacity with demand. Specifically, UCLA seeks to answer the following stakeholder question: What is the best way to operate their bus service within regulatory and policy guidelines?

Public transit ridership has been falling nationally and in California since 2014. The San Francisco Bay Area, with the state’s highest rates of transit use, had until recently resisted those trends, especially compared to Greater Los Angeles. However, in 2017 and 2018 the region lost over five percent (>27 million) of its annual riders, despite a booming economy and service increases. This report examines Bay Area transit ridership to understand the dimensions of changing transit use, its possible causes, and potential solutions. We find that: 1) the steepest ridership losses have come on buses, at off-peak times, on weekends, in non-commute directions, on outlying lines, and on operators that do not serve the region’s core employment clusters; 2) transit trips in the region are increasingly commute-focused, particularly into and out of downtown San Francisco; 3) transit commuters are increasingly non-traditional transit users, such as those with higher incomes and automobile access; 4) the growing job-housing imbalance in the Bay Area is related to rising housing costs and likely depressing transit ridership as more residents live in less transit-friendly parts of the region; and 5) ridehail is substituting for some transit trips, particularly in the off-peak. Arresting falling transit use will likely require action both by transit operators (to address peak capacity constraints; improve off-peak service; ease fare payments; adopt fare structures that attract off-peak riders; and better integrate transit with new mobility options) and public policymakers in other realms (to better meter and manage private vehicle use and to increase the supply and affordability of housing near job centers).

In the last ten years transit use in Southern California has fallen significantly. This report investigates that falling transit use. The project examines patterns of transit service and patronage over time and across the region and considers 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, the research concludes 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.
