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...

Power To Pedal: A Gendered Analysis of the Barriers and Joys of Cycling in Oakland

Gupta, Mallika
2024

Amidst increasing investments in cycling infrastructure in California, trends continue to demonstrate that women from low-income communities of color are underrepresented as cyclists. I argue that prevailing bicycle justice movements have neglected the intersectional needs of women from Black, Indigenous, and People of Color (BIPOC) communities by centering the ‘white, lycra-clad male’ and his commute needs within organized bicycling advocacy. Further, contemporary bicycle planning does little to investigate the barriers and joys related to cycling, as they are experienced by these women....

California’s Freeway Service Patrol Program: Management Information System Annual Report Fiscal Year 2019-20

Mauch, Michael
Skabardonis, Alex
2021

The Freeway Service Patrol (FSP) is an incident management program implemented by Caltrans, the California Highway Patrol and local partner agencies to quickly detect and assist disabled vehicles and reduce non-recurring congestion along the freeway during peak commute hours. The first FSP program was piloted in Los Angeles, and was later expanded to other regions by state legislation in 1991. As of June 2019, there were fourteen participating FSP Programs operating in California, deploying 338 tow trucks and covering over 1,806 (centerline) miles of congested California freeways. The...

Distributing Synchronous Programs Using Bounded Queues, a coordinated traffic signal application

Zennaro, Marco
Sengupta, Raja
2005

This paper is about the modular compilation and distribution of a sub-class of Simulink programs [10] across networks using bounded FIFO queues. The problem is first addressed mathematically. Then, based on these formal results, a software library for the modular compilation and distribution of Simulink program is given. The performance the library is given. The value of synchronous programming for the next generation of traffic control value is discussed. The adoption of these tools seems to be the natural candidate to address the needs of the traffic engineers. As a case study we present...

Advanced Air Mobility: Opportunities, Challenges, and Research needs for the State of California (2023-2030)

Cohen, Adam, MS
Shaheen, Susan, PhD
2024

Advanced air mobility (AAM) is a broad concept that enables consumers access to air mobility, goods delivery, and emergency services through an integrated and connected multimodal transportation network. AAM can provide short-range urban, suburban, and rural flights of about 50-miles and mid-range regional flights up to a several hundred miles. State law delegates responsibility for oversight in aviation primarily to the California Department of Transportation (Caltrans). This white paper presents an overview of the state of the market, such as the aircraft under development and forecast...

Policies to Improve Transportation Sustainability, Accessibility, and Housing Affordability in the State of California

Chatman, Daniel G., PhD
Barbour, Elisa, PhD
Kerzhner, Tamara
Manville, Michael, PhD
Reid, Carolina, PhD
2023

This report presents analytical review of empirical research on the interactions between housing availability and production, and travel behavior, accessibility, land use policies, and transportation policies. It identifies lessons from this review for California state legislative efforts to improve housing and transportation linkages, and to increase both transportation sustainability and housing affordability. Relevant California state efforts include legislation to influence parking standards; to require up-zoning near transit stations; to influence regional housing and transportation...

Bertini, Robert L.
Orrick, Phyllis
1998

This report is a summary of proceedings from a two-day symposium convened by the Institute of Transportation Studies at the University of California at Berkeley in April 1998 to commemorate the fiftieth birthday of the Institute and to lay the groundwork for the Institute’s second fifty years. With the title, The Transportation Enterprise: Challenges of the 21st Century, the Symposium set out to generate thoughtful, active discussion in preparation for laying out an action plan for the Institute in the21stCentury.

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...

The General Transit Feed Specification Makes Trip-Planning Easier — Especially During a Pandemic — Yet its Use by California Agencies is Uneven

Frick, Karen Trapenberg, PhD

2020

Developed in 2005, the General Transit Feed Specification (GTFS) is making transit trip planning easier by allowing public transportation agencies to share transit schedules in an electronic format that can be used by a variety of trip-planning applications, such as Google Maps. The GTFS can be used to share static transit schedules (GTFS-s) or provide real-time information on transit vehicle arrivals and departures (GTFS-r). Providing real-time updates has proven to be exceptionally valuable during the COVID-19 pandemic. For example, between January 13th and April 25th of this year Apple...

Intelligent Transportation Systems and Infrastructure: A Series of Briefs for Smart Investments

ITS Berkeley
2017

Intelligent transportation systems and technology provide a high return on investment, especially when incorporated as part of ongoing construction activities. Efficient operation and maintenance of our transportation infrastructure requires real time data exchange provided by ITS (Intelligent Transportation System) technology. The cost to acquire and install this technology is roughly 5% of the overall construction budget if installed during construction. The ROI (measured in safety, travel time reliability, throughput and quality of life) takes less than 6 months in highly congested...
