Impacts of New Mobility Services on the Use of Other Travel Modes in California

Webinar, Streamed Lived

Emerging transportation services, such as carshare and ride-hailing services (e.g., Uber, Lyft), are quickly changing how people travel. This webinar will highlight new research from Dr. Giovanni Circella exploring the factors affecting the adoption of these new services, how frequently these services are used, and the effect these services have on the use of other travel modes, including public transportation and driving alone. Insights presented on this webinar come from an ambitious data collection effort funded by the California Department of Transportation on the travel trends and lifestyle preferences of millennials in California, including residential location, technology adoption, car ownership, travel behavior, and future aspirations to purchase a vehicle.

Capitol Hill Research Briefing
Driverless, Shared, Electric:
The Three Transportation Revolutions

Briefing, Washington, DC

Briefing Description: The three revolutions in transportation - vehicle sharing, electrification and automation – stand to improve access, equity and public health in our cities. However, these disruptive revolutions could also lead to unintended consequences, including more traffic, worsening air quality and an imbalance between who benefits and who is burdened. Federal, state, and local governments are all moving quickly to be ready for the Three Revolutions, which makes this a timely and important area of study for the research community. This briefing will showcase the research of leading experts from the NCST demonstrating with quantitative and qualitative analysis, the best strategies for maximizing the benefits of new transportation technologies, and mitigating the burdens. The briefing will emphasize the importance of getting flexible policy frameworks in place now and how collaborations across institutions will enable communities to stand prepared for revolutionary changes to our transportation system.

La CoMotion-Heart of the Mobility Revolution

Expert Meeting hosted by partner Institutes of Transportation Studies at UC Davis and UCLA


With Los Angeles being a world renowned city notorious for congestion issues, it is the ideal place to discuss and work out solutions regarding transportation which must  be equitable and sustainable.

Austin Brown, Executive Director, UC Davis Policy Institute for Energy, Environment and the Economy says:“We are only just beginning to understand what these kinds of technologies are gonna mean. But we do know that this is a big enough transition we’re about to face that there are gonna be unintended consequences and so I think our job is to think through what those might look like and how to set this system up in a way that works for everybody, avoids the worse unintended consequences, and provides better equity, better efficiency, reduces congestion."

Acting now was the message that resonated among everyone, as stated by Juan Matute,  Associate Director, UCLA Lewis Center and the Institute of Transportation Studies, who made it clear that “We don't have to wait for the technology to do the things we want to do, and we know we need to do in order to shape the evolution of the transportation system which is new technology in a way that makes it so that its a transportation system that people wanna live with, people wanna use, its equitable, its environmentally friendly”

A sentiment shared by Michael Manville, Assistant Professor of Urban Planning, UCLA Luskin School of Public Affairs, who said: "If you have that sort of outcome based approach, you reduce the risk that you get caught up in any particular technological future and instead you keep in mind what you can control today and how you can take those regulatory controls and use them to whatever technology comes along and bend it towards the outcomes you want"

Policy Workshop: The 3 Revolutions for Cities

Ancillary meeting at the Meeting of The Minds Annual Summit, Marriot Key Center, Cleveland, OH

This workshop was attended by a group of 40 experts in transportation and land use. Participants took a deep dive into how the 3 transportation revolutions—vehicle sharing, electrification, and automation—will impact our cities. The workshop was moderated by Dr. Austin L. Brown, Executive Director of the UC Davis Policy Institute for Energy, the Environment, and the Economy, and Mollie D'Agostino, Program Manager of the 3 Revolutions Future Mobility Program. This summary key points arising from open discussion at the workshop. It does not necessarily reflect the official stance of any participants, speakers, or UC Davis.

Provocative questions were raised regarding policy priorities in the new transportation era that will deserve attention:

  • Will increased automation exacerbate the urban-rural divide?
  • Will pending federal automated vehicle (AV) policy preempt cities from taking independent action to manage automated vehicles?
  • How will infrastructure adapt fast enough to keep pace with innovation? Will something like “infrastructure-as a-service” bring new funding partners to transportation?
  • How can advances in transportation be made affordable and accessible to everyone, including people both young and old, non-English speakers, and those with mobility limitations?

Key Takeaways included a discussion of the following policy priorities:

Short term:

  • Foster spirit of innovation in public and private sectors.
  • Expand electric vehicle (EV) charging infrastructure, while ensuring equitable distribution of EV investments.

Medium term:

  • Pilot innovative solutions to evolve fixed route transit, and to meet the needs of an aging population.
  • Expand microtransit service.
  • Invest smartly in improving parking management.
  • Improve roadway pricing to better manage demand and prevent traffic.
    Improve parking pricing to better manage demand, and consider landbanking of lots for better management and repurposing.


  • Ensure that advances in transportation benefit diverse populations.
    Ensure that advances in transportation do not encourage sprawl.'

Will Driverless Vehicles Create a Better Future

Panel at the League of CA Cities Annual Summit, Sacramento Convention Center

Presiding: Dan Sperling, Founding Director, Institute of Transportation Studies at UC Davis
Speakers: Steve Heminger, Executive Director, Metropolitan Transportation Commission; Debs Schrimmer, Transportation Policy Manager, Lyft; Darrell Steinberg, Mayor, Sacramento

Driverless vehicles may bring exciting opportunities for increasing accessibility and improving travel efficiency, but an autonomous vehicle era also carries the possibility of worsening traffic congestion, increasing emissions, declining transit ridership, and the widening of the mobility gap. It is critical that innovative policies are developed in tandem with transportation technology innovation. Panelists responded to the following key questions:

  • Will driverless vehicles create more environmental benefits than unintended consequences?
  • Can we ensure there is equity of any societal benefits that driverless cars may offer?
  • Will the market address these key questions, or will cities need to develop policies to use incentives/disincentives to make driverless vehicles zero-emission vehicles, and/or to ensure driverless cars are "shared" or "pooled" over personally owned?

Policy Workshop

Pooling and Pricing:

Harnessing the 3 Revolutions to Solve Congestion, Climate Change, and Social Equity

Hosted by the 3 Revolutions Policy Initiative of the Institute of Transportation Studies at UC Davis 

Workshop Premise: Policies that apply price rewards and/or penalties to make pooled travel more attractive than solo driving show promise in tackling our biggest transportation challenges, including worsening traffic congestion, increasing emissions, declining transit ridership, and the widening of the mobility gap. But in the US, despite longtime popularity of pricing mechanisms among transportation experts, economists and planners, comprehensive travel pricing has struggled to gain political traction.

In June 2017, the 3 Revolutions Policy Initiative of the Institute of Transportation Studies at UC Davis hosted a workshop convening a select group of leaders in transportation to identify whether recent advances in the number of pooled travel choices offer new political opportunities to advance transportation pricing policies.   

This workshop marked a historic moment of innovation in transportation as hosts of new pooled choices have emerged including Lyftline, Uberpool, micro-transit services, carsharing, and bikesharing, as well as better integration of these services with the conventional pooled choices, rail and bus services. Automated vehicles will also soon likely add to the list of new types of pooled travel choices. Workshop participants discussed whether more choices will allow policymakers to leverage new pooled travel options to the level that they can compete with solo driving. Participants discussed whether a more socially equitable, more efficient and less environmentally damaging transportation system is within reach.

Summary of Workshop's Key Points on US Travel Market

  • US transportation policy to date: owning is easy, sharing is difficult. Historically, US policy supports the perception that driving alone is the best option. The best way to fill empty seats is simply to change this equation and make sharing a more attractive alternative.
  • But Americans still dislike riding with strangers. Carpooling is a failure for commute trips, carpooling dropped from cited 36% of carpool commute trips in 1980, compared to 9% today, despite billions spent on peak hour HOV lanes.
  • Travel using services like Lyft and Uber are still too expensive to replace private car ownership. Ridehailing and taxiing in the future will be cheaper, with better pooling options as well as the introduction of electric/automated cars.
  • US Public Transit is experiencing a much-needed evolution. US Transit Providers will require innovation to reduce per ride costs, reduce vehicle emissions, improve service, and maintain living wages for transportation sector employees. Opportunities abound to develop public-private partnerships, employ on-demand micro-transit, and consider innovative transit solutions. Innovation is likely coming to traditional transit service as well as dial-a-ride and paratransit service.

Critical Considerations from Workshop's Discussion with Public Leaders

  • Leaders and advocates need to better frame the tangible personal and societal benefits of pooled travel. Reframing pooling and pricing as win-wins for travelers and the transportation system. Frame pooling supportive pricing policies not as penalties to be minimized and applied gently, but as methods to improve travel, create economic opportunity, benefit the environment, etc.
  • Improved community support is needed for elected officials willing to stick their necks out against the status quo. Support is requested at local and regional public meetings to bring rational arguments as counters to change-averse public sentiments. A balance is needed to the metaphorical “people with pitchforks” who favor the status quo of solo driving subsidies over transportation innovation.
  • Improving transportation equity will look different for rural and urban communities.Travel needs vary considerably between rural, suburban and urban areas; and needs vary for workers, parents, seniors and low-income travelers. The most successful travel innovations will address the unique needs of communities and individuals and will not leave our most vulnerable neighbors stranded.
  • continued discussion is needed on how to fund services that don’t fit into existing state and federal mechanisms. Continued discussion needed to identify opportunities for special regional transportation taxes, that build in flexibility or inclusion in regional sustainable Community Strategies and a larger conversation needs to occur to identify what types of funding sources should be used to subsidize ridehailing service?
  • Notice anything missing? If you were an attendee and you took note of additional considerations to add to this list, please share these by emailing: 3rev@ucdavis.edu.

Case Studies and Research Examples Presented by Speakers and Discussants

Los Angeles Metro: Office of Extraordinary Innovation (OEI) Chief Innovation Officer, Dr. Joshua Schank described an exciting FTA funded pilot project launched in Seattle and Los Angeles to improve first-last mile transit access to a selected set of transit stations. The OEI is accepting opening proposals for innovative public-private partnerships to expand feeder service to transit terminals, pilot micro-transit van pickup service, and generally think about extraordinary ways to improve transit in L.A.

Research: Impacts of Transportation Technologies on Travel Behavior and Vehicle Ownership A recent National Sustainable Transportation Center study presented by Dr. Giovanni Circella from ITS-Davis and Georgia Tech, examines ridehailing impacts on travel demand, travel behavior, and vehicle ownership comparing Millennials and Gen-Xers. The study showed that a considerable portion of millennials reported that their use of Lyft/Uber contributed to reducing the amount of walking/biking they do and their use of public transportation.

Opportunities For Shared-use Mobility Services In The San Joaquin Valley Dr. Caroline Rodier, described her ITS‐Davis research project to expand accessibility with shared use mobility services in rural disadvantaged communities at a cost at or below currently available transit services. Rodier introduced several pilot concepts including one that crosses ridesourcing and round‐trip carsharing. It allows car renters/drivers to pick up a car and/or others traveling on a similar route, which makes trips more affordable.

Are we ready to jump back in the pool? Prospects for Carpooling and Ridesharing in the Years Ahead Professor Brian Taylor,  Director of the UCLA  Institute of Transportation Studies, presented data and research on shared mobility and argued that an increase in shared rides in the years ahead is not a foregone conclusion.  Indeed, noted Taylor, carpooling on commute trips decreased from 36% in 1980 to 9% today.  Taylor suggested that relatively low-cost subscription shared services may prove more attractive for many travelers than pricier privately-owned automated vehicles, offering a path toward increased ride-sharing in the years ahead.

100 Hours Campaign Amanda Eaken reviewed the social and environmental benefits associated with congestion charging schemes in London and Stockholm and described the 100 hours campaign (link to it) recently launched in Southern California to examine proven solutions to traffic congestion from around the world.

 Inaugural 3 Revolutions Conference: 

Hosted by the Institute of Transportation Studies at UC Davis

3 Revolutions 2016 Conference Premise: For the first time in many decades, the passenger transportation system is experiencing massive innovation. These innovations could lead toward dramatically different futures. One future could be more urban sprawl, energy use, greenhouse gas emissions, and unhealthy cities and individuals. The other future could bring huge public and private benefits, including more transport choices, greater affordability and accessibility, and healthier, more livable cities, along with less vehicle use and fewer greenhouse gas emissions.

This conference focused on key policies and strategies to put us on the latter path—focusing on potential synergies between electrification, automation, and vehicle and ride sharing, and those policies that enhance the synergies. Key questions included timing (will changes be evolutionary or revolutionary), role of different levels of government, and relative importance of different policy goals and innovations.
