“Don’t Keep Us Out of the Revolution!”: Accessibility and Autonomous Rideshare in California

Heuser, Katie L.
2024

Robotaxi services, or rideshare operated by autonomous vehicles, present an opportunity for independent and convenient transportation for people with disabilities. The proliferation of robotaxis in California has been met with mixed reactions from the disability community. To better understand perceptions of and expectations for robotaxis, this report uses semi-structured interviews with representatives from disability advocacy organizations. For many people with disabilities, especially for people with intellectual, developmental, and/or physical disabilities, robotaxis are inaccessible....

Future of Public Transit and Shared Mobility: Scenario Planning for COVID-19 Recovery

Shaheen, Susan, PhD
Wong, Stephen, PhD
2021

In 2020, the novel coronavirus (COVID-19) pandemic enveloped the world, leading to a public health crisis that profoundly changed all aspects of society, especially multiple sectors in transportation such as public transit and shared mobility. With so much uncertainty about the future of travel, the transportation sector needs to move rapidly to shape the nature of public transit and shared mobility services during the COVID-19 recovery period. Consequently, the University of California Institute of Transportation Studies (UC ITS) and the Transportation Research Board’s (TRB) Executive...

Examining the Potential for Uber and Lyft to be Included in Subsidized Mobility Programs Targeted to Seniors, Low Income Adults, and People with Disabilities

Deakin, Elizabeth, SM., J.D.
Halpern, Jeremy
Parker, Madeleine
2020

Public agencies have subsidized taxi rides for people who have difficulty driving a car or using the regular transit system – targeting older residents and people with disabilities. There is interest among public agencies to add transportation network companies (TNCs), such as Uber and Lyft, to subsidized ride programs as a travel option due to the widespread availability of TNCs and high-quality service. Key issues include the need for wheelchair accessible vehicles, subsidy needs, and clients who lack or are uncomfortable using a smartphone and credit card. This research included a...

Public Transit and Shared Mobility COVID-19 Recovery: Policy Options and Research Needs

Shaheen, Susan, PhD
Wong, Stephen, PhD
2020

While the COVID-19 crisis has devastated many public transit and shared mobility services, it has also exposed underlying issues in how these services are provided to society. As ridership drops and revenues decline, many public and private providers may respond by cutting service or reducing vehicle maintenance to save costs. As a result, those who depend on public transit and shared mobility services, particularly those without access to private automobiles, will experience further loss of their mobility. These transportation shifts will be further influenced by changing work-from-home...

Dashboard Cameras Combined with AI Provide an Affordable Method for Identifying Curb Usage

Arcak, Murat
Kurzhanskiy, Alexander
2024

The increasing reliance on transportation network companies (TNCs) and delivery services has transformed the use of curb space. The curb space is also an important interface for bikeways, bus lanes, street vendors, and paratransit stops for passengers with disabilities. These various demands are contributing to a lack of parking, resulting in illegal and double-parking and excessive cruising for spaces and causing traffic disturbance, congestion, and hazardous situations. How cities manage this public asset to support safety and the local economy relies on first understanding the usage...

The Benefits and Challenges of Incorporating Uber and Lyft in Subsidized Ride Programs that Serve Vulnerable Populations

Halpern, Jeremy
Deakin, Elizabeth
Parker, Madeleine
2020

Cities, transit agencies, and social service providers across the U.S. have implemented programs that provide taxi subsidies for people who have difficulty driving a car or using the regular transit system. These programs usually serve older residents and people with disabilities, though a few also serve low income users. Taxi subsidy programs provide curb-to-curb or door-to-door transportation at a fraction of the cost of paratransit.1 However, as Transportation Network Companies (TNCs), such as Uber and Lyft, have entered markets around the country, taxi availability has declined,...

Where are Private “Smart City” Transportation Technologies Concentrated in California?

Huang, Amy

2022

In recent years, “smart city” information and communication technologies have proliferated. For local government agencies, procuring and introducing these technologies offers the possibility to manage infrastructure assets more effectively, plan for preventive maintenance, and disseminate schedules and information about transit and other services. Many of these technologies are deployed by private firms in the context of local regulations and government-sponsored incentives. In the transportation sector, examples of “smart city” technology services provided by private firms include:...

Role of Trust and Compassion in Willingness to Share Mobility and Sheltering Resources in Evacuations: A Case Study of the 2017 and 2018 California Wildfires

Wong, Stephen D.
Walker, Joan L., PhD
Shaheen, Susan A, PhD
2020

Advances in the sharing economy – such as transportation network companies (e.g., Lyft, Uber) and home sharing (e.g., Airbnb) – have coincided with the increasing need for evacuation resources. While peer-to-peer sharing under normal circumstances often suffers from trust barriers, disaster literature indicates that trust and compassion often increase following disasters, improving recovery through additional resources and support. We hypothesize that trust and compassion could trigger willingness to share transportation and sheltering resources during an evacuation.

Peer-To-Peer (P2P) Carsharing: Understanding Early Markets, Social Dynamics, and Behavioral Impacts

Shaheen, Susan, PhD
Martin, Elliot, Phd
Bansal, Apaar
2018

Shared mobility services have now become firmly integrated into urban transportation systems across the globe. Carsharing, bikesharing, ridesourcing or transportation network companies(TNCs), and other systems now offer urban travelers access to transportation services that had long been previously only possible through personal vehicle ownership. Carsharing is arguably the pioneer mode of the sharing economy, given it ushered in a new way of thinking and access to the private automobile in the 20thcentury.Since its North American inception in Montreal in 1994, carsharing has undergone...

Impacts of Shared Mobility

Shaheen, Susan, PhD
Cohen, Adam
2018

Shared mobility modes have reported a number of environmental, social, and transportation-related impacts. Several studies have documented the reduction of vehicle usage, ownership, and vehicle miles traveled (VMT). Cost savings and convenience are frequently cited as popular reasons for shifting to a shared mode. Shared modes can also extend the catchment area of public transit, potentially playing a pivotal role in bridging gaps in existing transportation networks and encouraging multi-modality by addressing the first-and-last mile issue related to public transit access (1). Shared...
