Travel Behavior

Since the end of World War II, the passenger transportation system in the United States has been heavily based on the automobile for short haul travel and the airplane for long-haul travel. In this paper, we show that there is a growing potential for high speed rail in the United States caused partly by increasing congestion on the existing network and based partly on the higher speeds and higher service capabilities of new technology, high-speed rail. In defining the potential for high-speed rail over the next 40 years, we used two approaches: first, a bottom-up approach in which the...

A significant portion of the population stayed, and continue to stay, at home due to the COVID-19 pandemic. With more people staying home, online shopping increased along with trips related to pickups and deliveries. To gain a better understanding of the change in retail purchases and related travel, UC Berkeley researchers compared pre-pandemic shopping to pandemic-related shifts in consumer purchases in the greater Sacramento area for nine types of essential and non-essential commodities (e.g., groceries, meals, clothing, paper products, cleaning supplies). In May 2020, the research team...

This paper examines transit ridership and its role in downtowns in five San Francisco Bay Area cities pre- and post-COVID. We analyze 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). We draw upon focus groups we held with transit users and interviews we conducted with key stakeholders to gain additional information and insights. We found that trips to, from and within our five case study downtowns account...

This paper presents a case study of the use of San Francisco bike lanes with a focus on women. Bike counts and intercept surveys of cyclists at three locations in San Francisco’s SoMa District were complemented by focus groups with cyclists, particularly women cyclists, and brief interviews with non-cyclists. Consistent with other US studies, we find that white men are disproportionately represented among the cyclists we observed, and that women bike less and bike shorter distances. However, at least in the SoMa sample, women are more likely to bike to work than men. Cyclists included...
