A LOSS FOR THE PLANET: Remembering Alex Farrell

Dan Sperling and Alex Farrell at January 2007 news conference when
Gov. Arnold Schwarzenegger signed executive order creating the
low carbon fuel standard.

The news of Alex Farrell’s death struck like a lightning bolt. As we prepared this issue of e-news, ITS-Davis and the greater transportation research and policy community grappled with the sudden, unexplained loss of a colleague, a friend, a guiding light. Because he worked so closely with many of us here at ITS-Davis, it feels like a death in the family.

Farrell, 46, was an associate professor in the Energy and Resources Group at UC Berkeley. He was recognized internationally as a leading expert on transportation fuels and the role of transportation in climate change. His research interests included biofuels, hybrid electric vehicles and hydrogen vehicles, the low-carbon fuel standard and transportation sustainability.

Farrell co-directed with ITS-Davis Director Dan Sperling the team that worked on the state’s low carbon fuel standard study. Even though they shared the title, Sperling says Farrell was truly the principal investigator.

“In addition to all he did, this effort was the first time in my memory where we formed a collaborative research team with another campus and it really turned into a full collaboration in every sense of the word. And that was because of Alex,” Sperling said.

Farrell directed the ITS-Berkeley Transportation Sustainability Research Center. TSRC Research Directors Tim Lipman and Susan Shaheen, among his closest colleagues, wrote in an e-mail to colleagues, “Professor Alex Farrell was an inspirational leader, researcher, and teacher. We feel privileged to have worked so closely with him in launching the TSRC…The loss of his vision, energy, and enthusiasm is profound.” (Lipman and Shaheen are both ITS-Davis grads. Shaheen also is the ITS-Davis Honda Distinguished Scholar.)

Farrell’s death was widely reported in the media. Roland Hwang, director of vehicles policy at the Natural Resources Defense Council (and also a UC Davis grad), told the Los Angeles Times, “It’s going to be very difficult to find anyone like him. His contributions were tremendous, not just scientifically, but as a person. He did so much to bring together different groups.”

Among the many poignant remembrances that have circulated are these comments from
UC Davis Professor Joan Ogden, Co-chair of the STEPS program:

“Alex was a brilliant energy analyst, and was emerging as one of the new generation’s leaders in technology assessment and energy policy. He worked tirelessly to address the grand energy and climate challenges of our time, using his intellect, leadership and passion to help change the world. He was a highly creative person who was called to lead and educate, and participate in the public sphere.

“Today, I grieve not only for Alex’s family, friends and colleagues, but also for his students, current and future, who will not have the benefit of his guidance and inspiration, and for the public, who will not have the benefit of his counsel. He had a brilliant future ahead of him, and his loss affects many, in ripples throughout the energy community. I feel like a fellow warrior has fallen. I will miss him.”

Sustainable Transportation Center Update

SUSTAINABLE STREETS: Greening Communities, Improving Mobility

Sustainable downtown revitalization: 1st St., Livermore, CA
(Credit: Greg Tung, Freedman, Tung & Bottomley).

STC Visiting Practitioner Ellen Greenberg, AICP, is finalizing her year-long STC-funded Sustainable Streets Project. The goals of the project are:

  1. To introduce a framework for street design that addresses the three themes of ecology, movement and community, and defines each of these relative to sustainability objectives to which street design can contribute.
  2. To document built examples of designs that address some or all of the three themes in an exemplary way.
  3. To support and promote further research efforts by establishing a database of project information and identifying research that needs to be conducted and disseminated in order to order to promote design and implementation.

Greenberg has developed an impressive and comprehensive package of materials including 250 PowerPoint slides that include a Sustainable Streets Album, a reference guide, and bibliography, all of which are available or will soon be available from the STC website.

The album, for example, documents accomplishments in streets that have been built or are under construction in 28 American and Canadian case studies in 11 states and provinces. The album provides snapshots of each case, with descriptions, photographs, technical drawings, and insight from project sponsors. The examples are organized by four main topic areas: storm-water management; revitalization through infill development; neighborhood and tree preservation; larger roads that serve mobility. Additional material on the projects in the album is available for UC Davis students, researchers and faculty to use in their research.

The STC in partnership with U.S. EPA will host an online seminar series on sustainable streets starting in June. Check the STC website for details.

VISITORS AND MEETINGS: STC Welcomes Visitors to Campus

External Advisory Council
The UC Davis Sustainable Transportation Center welcomed members of its External Advisory Council to campus for its annual meeting in February. The external council comprises distinguished leaders from industry, govern­ment and academia with expertise that matches the STC’s focus areas of regional transportation planning, environmental planning and review, and energy policy.

Two students gave presentations on their STC-funded graduate research. Catherine Emond, a Transportation Technology and Policy student, and Anthony Palmere, assistant general manager of Unitrans, presented results from a class project that evaluated the potential for a Downtown-Campus shuttle for Davis. Julia Silvis presented findings on her dissertation, which investigates the interactions between seniors’ social networks and their travel behavior. Silvis hopes to shed light on how transportation-related carbon emissions are likely to change with the coming demographic shift, as well as on how seniors can maintain mobility, independence and quality of life as they age. 

UC Davis Professors Yueyue Fan and Alison Berry presented updates on their STC-funded research. Fan’s presentation focused on a new mathematical model to identify the optimal sequence of converting existing and under-construction high-occupancy vehicle (HOV) lanes to high-occupancy toll (HOT) lanes. Her model accounts for a wide range of factors, including social equity issues related to pricing strategies of toll lanes. Berry, who directs the Road Ecology Center, is expanding research on “road effect zones” to examine not only the extent of the zone, but also how various impacts are interrelated, and how these impacts could be minimized through pavement and roadside management activities.

The meeting also included an introduction to the STC’s Sustainable Streets Project, an update on other ITS-Davis initiatives and a visit to the UC Davis Design Museum’s Greenstop Exhibit, sponsored by the STC.

STC Welcomes RITA Administrator

Good food + good conversation + good contacts = successful event. The Sacramento Chapter of the Women’s Transportation Seminar (WTS) teamed up recently with STC for a reception on campus for students, faculty, and working professionals. The purpose was to highlight transportation careers and opportunities. WTS-Sacramento is devoted to supporting professional success in the transportation field by promoting excellence, growth, opportunity, and recognition. 

Research Results

SHAPING OUR ENERGY FUTURE: ITS-Davis Assists California and Federal Policymakers

As the State of California advances strategies for meeting its stringent air pollution, greenhouse gas and petroleum reduction goals, ITS-Davis researchers, students and recent grads are contributing technical expertise to strengthen the policymaking foundation. It’s a natural role for ITS-Davis’s interdisciplinary education and research approach, and it serves state policymakers and the people of California, as well as the university’s students who gain valuable hands-on experience. Often, the Institute’s work reaches beyond California, as well.

This issue of e-news touches on several events to which ITS-Davis is contributing research presentations, collaborative policy and organizational support, or both.

Reducing Greenhouse Gas Emissions from Passenger Vehicles – What’s Next?

ITS-Davis recently co-hosted with the California Air Resources Board a symposium to examine what additional steps can be taken to address the shortfall between currently planned passenger vehicle greenhouse gas emission reduction programs and the requirements of California’s Global Warming Solutions Act of 2006 (AB 32).

More than 100 policy makers, advocates, technical experts and academics came together to discuss current and coming technologies for cutting carbon from vehicles, as well as  policy mechanisms such as pricing and market mechanisms.

“What we’re doing here in California is somewhat of a model,” ITS-Davis Director Dan Sperling said in opening remarks. He added, however, that Europe and Japan are way ahead of the U.S. in terms of fuel-efficient vehicles and policy instruments in place.

Morning presenters discussed drivetrain efficiencies, weight reduction techniques, and the potential for diesel, hybrid, battery-electric and fuel cell vehicles for reducing greenhouse gas emissions. The afternoon session tackled policy mechanisms such as feebates, driver behavior, congestion-pricing and vehicle-miles-traveled. ITS-Davis’s Ken Kurani presented results of his recent work examining consumer response to fuel and vehicle prices—and the complicated signals that pricing represents.

ITS-Davis kudos go to STEPS Program Manager Joshua Cunningham, who organized and coordinated much of the symposium.

The symposium served as the first discussion of likely future vehicle policies in California, including revisions to the Zero-Emission Vehicle program and a follow-on to the vehicle greenhouse gas emission regulation, and the continuation of discussions already underway as part of the AB 32 scoping plan.

Global Warming Solutions for Caltrans

UC Davis pulled together some of its top researchers for a special half-day workshop designed to demonstrate to the state’s transportation planning agency, Caltrans, the breadth of transportation and climate knowledge available on campus. Organized jointly by Civil Engineering Professor Debbie Niemeier and UC Davis Sustainable Transportation Center Director Susan Handy, and sponsored by the STC, the workshop featured presentations ranging from smart growth and regional planning strategies to 100-year pavement planning.


PHEV Research Center Crafts a Research Roadmap for California

UC Davis PHEV Research Center research roadmap workshop.

Approximately 45 people gathered on campus in late April for a workshop to refine a Plug-in Hybrid Electric Vehicle (PHEV) Research Roadmap for the State of California. When finalized, the roadmap will guide state-funded research efforts to develop, demonstrate and deploy PHEVs. The UC Davis Plug-in Hybrid Electric Vehicle Research Center is developing the roadmap with funding from the California Energy Commission PIER Program.

The PHEV Center sponsored the workshop to seek research stakeholder input on a draft roadmap document that examines the state of PHEV technology and research, regulatory drivers, automaker advances, infrastructure, consumer behavior research, certification issues, environmental benefits and lifetime costs.

The final roadmap will be refined and CEC will host a public workshop to take additional comment on the plan.

Low-Carbon Fuels

Sonia Yeh

UC Davis and UC Berkeley researchers are continuing their technical analysis in support of the state’s rulemaking on low-carbon fuels. Dan Sperling together with Alex Farrell co-directed the team that drafted the initial plan released last fall. The state is now developing the regulatory framework for the standard. ITS-Davis researcher Sonia Yeh is heading up the UC Davis team.

OUT AND ABOUT: Spreading the Word about Plug-in Hybrids and Fuel Cells

Dahlia Garas at UC Day in Sacramento.

The Institute’s demonstration vehicles—a Toyota fuel cell hybrid vehicle (FCHV) and a converted plug-in hybrid electric (PHEV) Prius—are increasingly busy these days. Calls for their participation in public events are increasing due to public concern about rising gas prices and interest in alternative fuels.

PHEV Center Program Manager Dahlia Garas has been constantly out and about speaking at public forums, presenting to classrooms, attending events and showing off one of the PHEVs that are part of the PHEV Center’s research and outreach program. The same is true for new FCHV Program Manager Peter Dempster.

Together they represented the Institute at UC Day at the State Capitol, an annual event to highlight to the state legislature the many UC System contributions. They also met with students at a recent “Dinner with a Scientist” event in Stockton.

“One of the teachers I met at that event brought 50-60 students from Lodi Middle School to meet us and see the vehicles on campus during a visit a few weeks later,” Garas says.

Garas also recently presented to 100 enthusiastic attendees of the Green Innovations for a Clean California symposium, sponsored by California Assembly Member Mary Hayashi at Las Positas Community College in Livermore.

Of course, the cars were popular attractions again at the annual UC Davis Picnic Day in April, and at an Earth Day event in San Francisco’s Golden Gate Park.
