book cover image

"We stand at the beginning of a revolution in transportation and energy. Growing demand, resource constraints, and environmental imperatives will reshape our energy system - changing the way we travel and the vehicles we drive, and challenging the primacy of petroleum and the internal combustion engine. This transformation poses urgent questions today because of the decades needed for developing new fuel and vehicle technologies and changing the energy system. This book compares biofuel, hydrogen, and electricity pathways and options, and examines the policy and technology challenges ahead."

So reads the back cover of Sustainable Transportation Energy Pathways: A Research Summary for Decision Makers, a new 334-page book published by ITS-Davis (available in color and black and white paperback versions).

The book was written to help inform decision makers in industry and government about the potential costs and benefits of different fuel/vehicle pathways, and to illuminate viable transition strategies toward a sustainable transportation future. It draws heavily on insights gained from the four-year ITS-Davis Sustainable Transportation Energy Pathways (STEPS) research program. STEPS began in 2007 with a goal of performing robust, impartial comparative analyses of fuel/vehicle pathways by drawing on UC Davis and other programs’ expertise in engineering, economics, environmental science and consumer behavior. The program’s second phase, NextSTEPS, is now underway, with researchers working to create scenarios and tools, analyze policies, and develop detailed regional studies for parts of the U.S., China and Europe.

The book was edited by STEPS director and UC Davis professor Joan Ogden, with technical editor Lorraine Anderson.

ITS-Davis Symposium Celebrates Two Decades of Learning and Research
“What do you think of when you think of ITS-Davis?”

Pat Mokhtarian

Professor Pat Mokhtarian, associate director of education, posed this question in her opening comments at the Institute of Transportation Studies’ 20th Anniversary celebration in late September. In a humorous and heartfelt look back over the past 20 years, Mokhtarian highlighted the Institute’s key growth indicators, milestone events, and numerous faculty and student research accomplishments. But in the end, she concluded, the Institute’s great achievements are a reflection of its people.

“When I think of our students, I think of the mark they’re making on our lives, and I hope, the mark we’re making on theirs.”

More than 150 people - current students, alumni, faculty, researchers, corporate supporters and friends - came together to celebrate the occasion. The daytime Symposium featured panel discussions on infrastructure issues, environmental vehicles and next-generation fuels, and land use and travel behavior. The evening festivities included a gala reception and dinner

Throughout the day, accomplished alumni presented their current research, described how their UC Davis education prepared them for their careers, and explored the compelling transportation issues that are the Institute’s focus.

Yu (Marco) Nie, Ph.D. ’06, Assistant Professor, Northwestern University, opened the first panel by acknowledging the Institute’s unique approach to education. “The fact that we’re encouraged to integrate these grand challenges of our time into our individual disciplines is what makes ITS-Davis such an important institute in this country.”

Konstadinos Goulias, Ph.D. ’91, one of the Institute’s first grads and now a professor at UC Santa Barbara, recalled insight he gained from ITS-Davis Director Dan Sperling. “He told me ‘Have a mission in your life. Tell yourself you’re going to make a change, make a difference.’ ”

Oliver Gao

Oliver Gao, Ph.D. ’04, Associate Professor, Cornell University, said he appreciated the freedom and flexibility of the academic program here as well as the tools and opportunities it provides to help students grasp new concepts quickly, and be able to analyze them thoroughly. “It goes hand in hand with the kind of pressure we face in the real world.”

Wayne Leighty
 Wayne Leighty

Wayne Leighty, M.S. ’08 and Ph.D. ’10, now a policy and regulatory affairs analyst at Shell Oil Company, said the Institute’s interdisciplinary focus prepared him for his current job. He said he uses his economic and business training the most, but also relies on his technical training to keep up with the engineers. He urged current students to take the opportunity to work in teams, practice communications and presentations, and accept internships to hone the skills that will be essential in their careers.

Anthony Eggert
 Anthony Eggert

Anthony Eggert, M.S. ’01, Deputy Secretary for Energy Policy, California Environmental Protection Agency, highlighted ITS-Davis’s role in informing California’s climate change policies that address vehicles, fuels and land use. “The basis of these policies was technical analysis – the work of a lot of people who’ve been through the Institute.”

One of the day’s recurring themes was the apparent disconnect between transportation researchers and policymakers. ITS-Davis Researcher Deborah Salon, Ph.D. ’06, noted that it is only on rare occasions that information gleaned from university modeling research gets used in decision making. ITS-Davis Director Dan Sperling added that his experience as an appointed California Air Resources Board member has given him new insight into the policy process and sparked an idea that he hopes will soon come to fruition.

“I also have a passion,” Sperling said at the close of the Symposium. “I want to do a better job of connecting research with policy.” As he spoke, a certain twinkle in his eye told the audience that the man who had a big idea 20 years ago now has another that will keep him going for at least 20 more.

Asilomar 2011: Best Ever, Say Many
Asilomar conference session
Attendees line up to comment during a
session Q & A.
Many attendees of the 13th Asilomar Conference on Transportation and Energy
in August considered this the best yet of the series, which is hosted biennially by ITS-Davis under the auspices of the Energy and Alternative Fuels committees of the U.S. Transportation Research Board (of the National Academies). More than 280 people participated, setting a record.

The Asilomar Conference brings together leading transportation, energy and policy thinkers in a casual, open and collegial setting that fosters discussion, debate and creative problem-solving. This year’s theme, “Rethinking Energy and Climate Strategies for Transportation,” recognized that political progress toward a secure, low-carbon transportation future is slowing, spurring the need and the opportunity to explore new strategies and government approaches.

Asilomar BBQ
  The barbeque is a social highlight of
  the conference.
The conference presentations and discussions pointed to an abundance of technologies and fuels competing for market dominance in the drive to improve transportation options for people around the world. But ensuring both mobility and sustainability in an increasingly industrialized global society necessitates creative policy making and changes in human behavior. Addressing the human factor – communications, consumer response to technologies, and policies designed to shape human behavior – was a significant focus of this year’s gathering. Other key themes included reframing the debate to focus on the co-benefits of climate strategies, and developing a portfolio of policies that deal with vehicles, fuels and land-use while taking into account the human behavior conundrum.

Asilomar is made possible by the generous contributions of many private companies, foundations and government agencies.

Books and other publications from past Asilomar Conferences are posted here.

Nobody had any idea what was in store when UC Davis Chancellor Linda Katehi and ITS-Davis Director Dan Sperling stepped on the riser at the ITS-Davis 20th Anniversary Gala – until Sperling gently lifted the Salmanazar of champagne from its bed of ice to show the attendees. The anticipation grew as first Sperling, then Katehi, then a string of current and past Institute students and researchers took a turn of the cork. And another turn. And another.

How many Ph.D.’s does it take to open a bottle of champagne? Watch the video here!

Festive blue and gold balloon bouquets and floral centerpieces adorned the UC Davis Conference Center ballroom, where the celebration continued into the night with a toast to the Institute’s accomplishments of the past and plans for the future.

Katehi told the audience that when she first came to Davis as the new chancellor, she sought out the leaders – “the wise people” – on campus. Sperling, she said, was one of those people.

Jack Short at ITS-Davis 20th Anniversary Gala

 Transport Forum

Keynote speaker Jack Short, the immediate past secretary general of the International Transport Forum, touched on the daytime Symposium’s discussions about infrastructure, road pricing and implementing policy. Drawing on the themes of the day, he acknowledged that technology advances and traditional transportation research, modeling and analysis, alone, are not enough to reach sustainability. “Planning in the broad sense – the transport system of all modes together,” is critical, he said, adding that the study of human behavior in disciplines such as psychology and sociology is one of ITS-Davis’s great strengths. “The multidisciplinary approach is a strong trump card that you have.”

True to his Irish heritage, Short closed his speech with a limerick for his friend and colleague Sperling:

A nasty rumor Dan hears
After all his blood sweat and tears
They want to put him in clover
And tell him it's over.
“No way,” says Dan. “I’m here for 20 more years.”

Fond Farewell to Lee Schipper
Lee Schipper

Lee (Leon) J. Schipper, a longtime friend, colleague and internationally acclaimed transportation and energy researcher, died in August of pancreatic cancer. He was 64.

At the time of his death, Schipper, also known as “Mr. Meter,” was a research scientist for the Global Metropolitan Studies Center at UC Berkeley and senior research engineer at the Precourt Institute of Energy Efficiency at Stanford University. He had returned to the Bay Area in 2008 after 13 years away, first in Paris at the International Energy Agency, then with EMBARQ, the World Resources Institute Center for Sustainable Transport, which he helped found. Schipper worked for 20 years at Lawrence Berkeley Lab before leaving in 1995. He received a Ph.D. in astrophysics from UC Berkeley.

A memorial website describes Schipper as an “…international physicist, researcher, musician and
co-founder of EMBARQ [who] inspired and shaped the thinking of a generation of students and professionals and was widely recognized for enriching policy dialogue with his passion for data and challenging conventional wisdom.”

The New York Times called him an iconoclast.

Learn more about a scholarship honoring Schipper here.

Schipper was a longtime member of the Steering Committee for the ITS-Davis Asilomar Conference on Transportation and Energy. His death, only days before this year’s 13th Biennial Conference, created a void at the gathering. In addition to missing his quick wit and sharp mind, attendees felt the absence of his music, which he shared every year with his band, The Mitigators. Asilomar attendees lined up at a memorial service to remember Schipper and another Steering Committee member, Jack Johnston, who passed away earlier this summer.

Schipper’s illness spurred tributes from colleagues around the world, including this memory from ITS-Davis Director Dan Sperling:

“You challenged us all, and because of your passion for data and keeping us honest, plus your zest for life, you were
a joy to be with! You inspired me and so many others. We will carry on your life’s work.”

STC Awards Faculty Research Grants and Dissertation Fellowships
The Sustainable Transportation Center is funding three faculty research grants and three dissertation fellowships for students for the 2011-2012 academic year.

2011-2012 Faculty Research Grants

Patricia Mokhtarian, Civil and Environmental Engineering and Institute of Transportation Studies
“Activities Conducted While Traveling: An Empirical Examination of Their Impact on the Value of Travel Time Savings”

This grant will support the administration, data management and analysis of a survey of California commuters. The study will help researchers better understand the travel choices people make – particularly how the ability to multitask while traveling influences those choices (potentially in favor of public transportation) – which will inform and improve policies and lead to more realistic models and forecasts.

Cynthia Lin, Agricultural and Resource Economics, and Environmental Science and Policy
“Optimal Gasoline Taxes and the Elasticity of Demand for Gasoline”

This project seeks to estimate and analyze the elasticity of demand for gasoline and calculate the optimal gasoline tax for various regions of the world, including the United States, China and Latin America. Elasticity of demand is a measure of how responsive consumers are to changes in the price of gasoline. The higher the elasticity in magnitude, the more consumers will decrease gasoline consumption in response to an increase in gasoline price. Understanding the factors that affect the elasticity of demand for gasoline is important for the design of transportation and energy policy.

Mark Lubell, Environmental Science and Policy
“Social Networks and Travel Behavior”

This proposal draws on the theory and methods of network science to understand how social networks influence travel behavior, specifically that of UC Davis students. Network science has found that social networks exert a profound influence on individual behavior, yet its application to transportation research is relatively new. This project will improve our understanding of the social factors involved in individual transportation behavior and provide insight into how social networks may be a tool for policies encouraging the use of sustainable transportation choices.

Mobile Programming for Transportation Applications: Is There an App for That? Yes, and There’s a Class for That, Too!
Michael Nicholas
 Michael Nicholas is never far
 from his cell phones.
Like many of his contemporaries, ITS-Davis postdoctoral researcher Michael Nicholas loves electronic gadgets. He and his smart phone are rarely separated. When he was a student, Nicholas says, he wanted to take a class in mobile programming. “I wanted to use my mobile phone for research but no one taught mobile programming in our discipline,” he recalls. So, with help from fellow researcher Justin Woodjack, Nicholas decided he’d develop his own course.

Now a researcher at the Plug-in Hybrid & Electric Vehicle Research Center, Nicholas first offered the class last spring and plans to offer it again in Winter Quarter 2012. It includes an overview of general concepts applicable to all mobile platforms, but maps and GPS are the main topics covered. The specific platform choice for final projects is up to the individual student; Android and iOS were the most popular platforms last spring. Students Tai Stillwater and Geoff Morrison developed an app to determine optimal speed for driving to save fuel. Another student created an app to show a map of Davis bicycle facilities, such as air pumps and repair shops.

“Students have a strong personal motivation to take this class,” Nicholas says, adding that it has been a positive experience. “I’ve learned programming, myself. I’ve learned about mapping and GPS capabilities. It’s been great.”

STC and UCTC Join Forces for New Regional Center
The UC Davis Sustainable Transportation Center has launched a new initiative to enable the center to continue its important research, education and outreach activities in coming years. STC has joined forces with the University of California Transportation Center (UCTC) on a proposal for a regional center that reflects the priorities of both the UC Davis-based STC and the broader UCTC program.

The proposal responds to a recent U.S. Department of Transportation Research and Innovative Technology Administration (RITA) announcement that it is overhauling its University Transportation Centers program, which funds the Sustainable Transportation Center. As part of the overhaul RITA announced an open competition for 22 new centers.

The proposed new “UCTC 2.0” center builds on the world-renowned transportation programs of the University of California system and decades of successful collaborations among the UC campuses. It would be organized around the themes of environmental sustainability, livability and economic competitiveness. Funding would go towards research, fellowships, education and technology transfer and outreach, with 20 percent of the research budget set aside for intercampus projects. Several California State University campuses would also participate in collaborative research and educational programs.
