ITS-Davis e-news presents information on research, education, and outreach from the UC Davis Institute of Transportation Studies and affiliated campus departments that host transportation-related programs. For previous issues, visit the e-news archives.
The Institute’s wildly successful Sustainable Transportation Energy Pathways (STEPS) Program
wrapped up its first four years, and in January launched a second phase of the industry-government-academia collaboration that
produces public-domain research on strategies for future fuels and vehicles.
NextSTEPS is now entering a new creative design phase, says STEPS Director Joan Ogden, a professor
of Environmental Science and Policy. “STEPS was about building tools to understand the different
fuel pathways. Now we’re going to put those tools together to create practical visions that will
help lead to a more sustainable transportation future.”
The mission of STEPS was to create robust comparisons of different fuel and vehicle pathways and
to transfer that knowledge to stakeholders in the decision-making process. STEPS research advanced
the state of knowledge about alternative fuels and vehicles, including biofuels, electricity,
hydrogen, and fossil fuels, and brought an impartial, rational voice to the debates. STEPS data
collection and modeling work “provided an information base grounded in technical and economic
reality from which to apply a vision of the future,” Ogden says.
“When we started, there weren’t a lot of good apples-to-apples comparisons of fuels,” Ogden recalls.
The results made clear that no single fuel or transportation approach will enable us to cut our
oil use and greenhouse gases emissions the way we need to, to meet our societal and policy goals.
“We need a portfolio approach that includes efficient vehicles, reduced travel demand,
electric-drive vehicles and de-carbonized fuels,” says Ogden.
More than 100 attendees at the January STEPS Symposium reviewed results of the program’s first
four years and discussed plans for the next phase. Among the planned NextSTEPS projects are
development and refinement of the “TIMES” energy-economic model to evaluate greenhouse gas
policies, led by ITS-Davis researcher Sonia Yeh; analyzing the volume and kinds of water needed
and used for biofuels production, led by Transportation Technology and Policy Ph.D. student Gouri
Mishra; and designing renewable energy intensive futures, led by ITS-Davis researcher Mark
Delucchi (see story below).
Like STEPS, NextSTEPS will bring together multiple researchers working in complementary disciplines.
They’ll build on the data from STEPS to create scenarios and tools, and analyze policies. They’ll
generate visions of the future and develop detailed regional studies beyond California – for parts
of the United States, China, and Europe.
STEPS ended as a hugely successful $8 million collaborative, involving 19 sponsors, 15 faculty,
25 graduate students, and 12 academic programs or departments. NextSTEPS is well on its way to
matching the success of the first phase. Initial sponsors include BMW, BP, Caltrans, CARB,
Chevron, Nissan, Shell, South Coast Air Quality Management District, and the U.S. Department
of Energy.
Powering the world with energy from wind, water, and sunlight may sound like the stuff of dreams –
but it’s feasible, says UC Davis researcher Mark Delucchi. In a two-part paper published in December
in Energy Policy, Delucchi and Stanford’s Mark Jacobson determine what it would take to power the globe
solely with renewables, and what it would cost.
Research from more than 50 UC Davis faculty and students was presented at the annual gathering of the
Transportation Research Board in Washington, DC in January. See the complete list of presenters and
papers here.
The UC Davis Plug-in Hybrid & Electric Vehicle (PH&EV) Research Center, part of ITS-Davis, ended
its second year by producing two high-profile research reports containing valuable insight to aid
policymakers.
Printed copies of the state’s plug-in electric vehicle plan, “TAKING CHARGE: Establishing California
Leadership in the Electric Vehicle Marketplace” are now available. ITS-Davis PH&EV Research
Center staff led the research and writing of the plan, which was formally released by the California
Plug-in Electric Vehicle Collaborative in December. For print copies contact Tobias Barr
of the PH&EV Research Center. Download an electronic copy of the plan here.
The second-year report of the PHEV Demonstration and Consumer Education, Outreach, and Market
Research Program summarizes the results of the program’s ongoing study of consumer response to
plug-in hybrid vehicles. Among the findings, two are fundamental. First, consumers don’t understand
the benefits of all-electric driving made possible by some PHEV designs, and this lack of
information reduces demand for those designs. Second, anyone who wants to promote PHEVs and their
benefits to consumers needs to communicate in language consumers understand. Read more in the
latest ITS-Davis Research Findings.
ITS-Davis is fortunate to be able to offer a number of fellowships to our students for the 2010–11
academic year. The recipients are announced in e-news as the awards are given.
Abbas Ghandi
Sahoko Yui
ITS-Davis this year created academic fellowships in the name of each company that supports the
Institute’s Corporate Affiliate Program at the Patron Level. The first two of these prestigious
new fellowships have now been awarded. Abbas Ghandi, a Transportation Technology and Policy Ph.D.
student who began his UC Davis studies in fall 2007, received the inaugural ITS-Davis Corporate
Affiliate Fellowship, the ExxonMobil Fellowship. Anthony Santamaria, a Mechanical and Aerospace
Engineering Ph.D. student working in the Green Transportation Lab under Professor Jae Wan Park,
received the Daimler Fellowship.
Sahoko Yui, a first-year Transportation Technology and Policy master’s student, is this year’s AAA
Greenlight Fellow. This annual fellowship, sponsored by AAA Northern California, Nevada & Utah, was
established at ITS-Davis to attract more minority students to the transportation field, specifically
to encourage the study of alternative fuels and other vehicle efficiency technologies.
Susan Pike
Amy Lee
UC Davis students are this year’s recipients of all three Women in Transportation – Sacramento
scholarships. The honors were presented at the annual WTS Awards Banquet in Sacramento in December.
Susan Pike, a Transportation Technology and Policy master’s student working with
professors Pat Mokhtarian and Mark Lubell, received the Helene M. Overly Memorial Graduate
Scholarship. The Sharon D. Banks undergraduate scholarship went to Amy Lee, a senior
in Environmental Policy Analysis and Planning who is working with Professor Susan Handy. Julie Peri,
a senior in Civil Engineering, received the Louise M. Molitoris Leadership Fund award.
Papers authored by ITS-Davis researchers made two of Elsevier Publications’ Science Direct “Top 25
Hottest Articles” lists for the 2009–10 academic year. The papers were published in either Transport
Policy or Transportation Research Part D and are listed below.
STC
Outstanding Student of the Year David McCollum, left, with ITS-Davis researcher Chris Yang and
student Adina Boyce, winner of the Neville A. Parker award, at the CUTC Awards Banquet at TRB
Transportation Technology and Policy Ph.D. student David McCollum is the STC’s 2010–11 Outstanding
Student of the Year. McCollum was recognized for his achievement at last month’s Council of
University Transportation Centers banquet at the annual TRB conference in Washington D.C.
For his dissertation research, McCollum is developing a California economic and energy model to
analyze the state’s greenhouse gas policies and study options for achieving long-term energy and
climate objectives. McCollum has received numerous awards and fellowships for his accomplishments
at UC Davis, including the best master’s thesis award in 2007–2008 for his comprehensive study of
the likely effects of expanded use of coal on the nation’s rail system, an Eisenhower Fellowship,
and a Fulbright research grant, among others.
The Sustainable Transportation Center has awarded six faculty research grants and four dissertation
fellowships for the 2010–11 academic year.
Faculty Research Grants support the named faculty researcher and at least one
graduate student. The 2010–11 faculty recipients are:
YueYue Fan
“Renewable Energy Supply Chain Disruption Management”
YueYue Fan is using a stochastic modeling framework that incorporates various risk measures to
develop methods for managing disruptions in renewable energy supply chain systems. Such breakdowns
could occur in response to common supply and demand fluctuations (recurrent risks) or facility
breakdowns or natural disasters (non-recurrent risks).
Chris Knittel
“Carbon Pricing Policies and Their Effect on Greenhouse Gas and Criteria Emissions”
Chris Knittel is studying the impact of pricing greenhouse gases on both greenhouse gas and criteria
pollutant emissions. The goal is to test the belief held by many policy makers that increasing the
cost of driving has little effect on consumer behavior and thus emissions. The project will add to
our broader understanding of how consumers respond to increases in the cost of driving and how this
response affects emissions.
Pat Mokhtarian
“How Permanent are Construction-Induced Adjustments in Commute Behavior? Change Persistence Six
Months after the Fix I-5 Project in Sacramento, California”
Temporary events may induce many changes in travel behavior, some of which may lead toward more
sustainable commute patterns. But to what extent do those changes persist after the event concludes,
and what influences some people to maintain the new behavior indefinitely while others return to
their previous pattern as soon as possible? Pat Mokhtarian intends to find out in this follow-on
project. Find out more here.
Deb Niemeier
“Understanding How Public Perceptions of Road Diets are Formed”
Local projects that facilitate well-planned non-motorized transportation options will be critical
for meeting the nation’s greenhouse gas and oil reduction goals – and public acceptance of such
projects is critically important. Deb Niemeier will survey residents and businesses in Davis about
a proposed “road diet” project in the city. Her research findings will guide policymakers in
developing outreach tools for other similar projects nationwide.
Deborah Salon
“Evaluating the Impact of Local Actions on Vehicle Miles Traveled: Case Study in Davis, CA”
Deborah Salon’s project continues a series of before-and-after studies of the effects of three
local land-use projects in Davis on vehicle miles traveled in the city. The three changes are the
opening of the first “big box” retail store in Davis, the opening of an innovative mixed-use
development, and a vehicle lane reduction/bicycle lane addition project on a major arterial road
adjacent to downtown. Her experiences on these studies will contribute to the development of methods
that communities themselves can use in evaluating the effectiveness of policies to reduce greenhouse
gas emissions from driving.
Michael Zhang
“Credit-based Pricing for Multi-user Class Transportation Facilities”
Michael Zhang will develop a novel carrot-and-stick strategy, called Arc-Based Credit (ABC) system,
as an alternative to traditional congestion management strategies such as toll roads. The ABC system
has the potential to improve road system performance without making any road users worse off, while
generating enough revenues to pay for itself.
Dissertation Fellowships support the research of Ph.D. students who have
advanced to candidacy and are working on their own original research. The 2010–11 fellowship
recipients are:
Yi-Ru Chen
“Modeling Vehicle Interactions in the Ramp Merge Area”
Joeri F. de Wit
“Estimating Demand and Cost Functions for Hybrid-Electric Vehicles in the BLP Random
Coefficients Model”
David McCollum
“Modeling Optimal Transition Pathways to a Low Carbon Economy in California: Impacts of Advanced Vehicles and Fuels
on the Energy System”
Tai Stillwater
“How Real-time Energy Feedback Influences Driving Behavior and Fuel Economy”
Professor Pat Mokhtarian gets the limelight in the February issue of U.S. Department of
Transportation’s Spotlight newsletter. “Road Closed: How do Consumers Cope?” summarizes Mokhtarian’s work on
commuter response to Sacramento’s “Fix I-5” project. Even though the highway closure during summer
2008 is now just a commuter’s distant memory, Mokhtarian continues to mine the valuable data. Her
continuing I-5 research is funded in part by the STC.
We hear a lot of talk about sustainability, livable cities, and healthy communities these days, but
putting that talk into practice is an evolving process that requires research and policy change.
The Research and Innovative Technology Administration of the U.S. Department of Transportation last
fall hosted a conference that brought together a growing field of researchers and practitioners to
share research results, explore practical challenges, and identify potentially promising directions
for future research. The gathering came at a time when land use and livability policy debates are
front and center in California, and across the nation.
STC Director Susan Handy served on the organizing committee and as such was a central figure in the
shaping of the meeting. She also gave a presentation on the Impact of Community Design on Travel Behavior and served
on the closing panel. Handy’s presentation discussed the need for better evidence on the impact of the
built environment on walking for transport, bicycle commuting, and transit use.
“We know pretty well that community design can increase transit, walking, and bicycling and reduce
driving,” says Handy. We also know that substantial changes in the built environment may be needed
to achieve meaningful changes in traveler behavior. What we need now, she adds, are evaluation
studies that provide direct evidence that a change in the built environment leads to a change in
travel behavior. We also need more research on demand for livable communities – meaning the degree
to which people will choose to live in such places, and on supply of livable communities – meaning
development and planning policies that support and facilitate livable communities.

Nic Lutsey with Andi Kasarsky and ITS-Davis Director Dan Sperling
Nic Lutsey Wins Prestigious TRB Barry McNutt Award
ITS-Davis alumnus and post-doctoral researcher Nic Lutsey received the prestigious Barry McNutt Award at the annual Transportation Research Board
conference in Washington. With Lutsey’s award, ITS-Davis researchers have now won the honor three out of the last five years. Dan Sperling was the
2008 recipient. Joan Ogden, with then-student Mike Nicholas, received the award in 2007. Lutsey has been instrumental in supporting California Air
Resources Board climate and transportation policy development, and, in addition to his research post with ITS-Davis, is a researcher with the International
Council on Clean Transportation.
The award, given annually by the Energy and Alternative Fuels Committees of the TRB, is named for Barry McNutt, who, during his 35 years of transportation
and energy policy analysis, made major contributions to national energy and environmental policies for transportation. The award recognizes outstanding contributions
to the development of efficient and effective federal policies related to the automotive sector.
CUTC Awards Two, Now at UC Davis
Two UC Davis representatives are among the Council of University Transportation Centers Award winners recognized at
the annual CUTC awards banquet at TRB in Washington. Adina Boyce, now a Civil and Environmental Engineering Ph.D.
student, won the Parker Award for Outstanding Non-thesis Master’s Degree Paper in Science and Technology for work
she completed at City College of New York. Gian-Claudia Sciara, a post-doc working with the Urban Land Use and
Transportation Center (ULTRANS), received the Wootan Award for Outstanding Ph.D. Dissertation in Policy and Planning.
Inaugural Kitamura Paper Award Given
Two UC Berkeley students, D.J. Gaker and Yanding Zheng, and UC Berkeley assistant professor Joan Walker, are the recipients of the
2010 TRB Kitamura Best Paper Award. The award was established by the
Transportation Research Board to honor Ryuichi Kitamura, a much-loved and respected UC Davis and Kyoto University professor and
internationally heralded transportation scholar, who passed away in 2009. A cash prize supported by contributions to the
Ryuichi Kitamura Fund is given to the winners. Over time, the
fund will also help support the expenses of a young scholar in travel behavior research (or a closely-related field) from
a university in the East to collaborate with researchers at any UC campus with a transportation program, or vice versa.
UC Davis Ranks at the Top
UC Davis ranked first nationally in “U.S. Institutions: Most Prolific in Environment/Ecology, 2005-2009.” The new ranking is from
ScienceWatch (Thomson Reuters) and is for the greatest number of papers
to the field of environment/ecology over a recent five-year period.
The 90th annual Transportation Research Board meeting wasn’t only about serious topics and hard work. In fact, there’s always some play,
and ITS-Davis is known for contributing to the fun. The ITS-Davis annual reception is now legendary! The reception, held in the
historic Churchill Hotel, always draws a wide spectrum of attendees from seasoned transportation and research pros to new students with
fresh ideas. The diversity stimulates creative discussion that bubbles forth fueled by the relaxed, casual atmosphere. A good time is had by all.
Professor Andy Frank, widely known as the “Father of the plug-in hybrid electric vehicle,” was one of the first
Northern California residents to purchase and receive a Chevy Volt, the first commercially available PHEV. Frank
gained worldwide acclaim for his demonstration and groundbreaking student-design contest-winning vehicles that
combined efficient gasoline engines with batteries. Local media took notice when Frank picked up his new baby at a local dealer in December.
The Governors’ Global Climate Summit 3, held on campus in mid-November, brought
together subnational leaders from around the world to address the effects of climate change and build the emerging green
economy. The summit, cosponsored by UC Davis and supported by ITS-Davis and other campus research programs, was co-hosted
by Governor Arnold Schwarzenegger and other subnational leaders in partnership with the UN Development Programme and UN
Environment Programme. As the summit closed, ITS-Davis hosted an up-to-the-minute
briefing on California’s vehicle, fuel,and land use policies. Following the briefing, the Boards of Advisors of ITS-Davis
and the UC Davis Energy Efficiency Center combined for a dinner featuring remarks by CARB chairman Mary Nichols.
Both advisory boards held productive meetings the following day.
