ITS-Davis Director Dan Sperling last month learned he is one of ten national environmental innovators to receive a prestigious Heinz Award.
Sperling was honored for his significant contributions to revolutionary transportation and energy research.
The Heinz Award commends Sperling for his creativity in developing the unique academic model that is the heart of ITS-Davis, an approach that merges research, policy studies, and entrepreneurship in pursuit of clean,
equitable transportation options. The award also recognizes Sperling as instrumental in passage of California’s groundbreaking Low Carbon Fuel Standard.
“To have a member of the UC Davis faculty receive this year’s Heinz Award recognizes the university’s embrace of global sustainability and green technology,” said UC Davis Chancellor Linda Katehi.
“I congratulate Dr. Sperling and all in the university community who cultivate a culture of innovation, effectiveness, and stewardship.”
California is adopting revolutionary policies to reduce greenhouse gas (GHG) emissions by encouraging “smart growth”
so that people can live close to where they work and play and reduce vehicle use. ITS-Davis researchers from the
Urban Land Use and Transportation Center (ULTRANS) are involved in a multi-year project that is guiding state and
local policy makers as they implement a new state law that sets these new practices in motion, ultimately improving transportation choices.
Last month, the California Air Resources Board adopted targets for reducing GHG emissions by reducing sprawl and vehicle use.
These GHG targets are applied to each of the state’s 18 metropolitan planning areas. The decision capped a two-year, bottom-up process
in which cities, counties, the public, and ARB worked together to define the targets for each region. How the regions meet their
targets will depend on the policies they develop.
ULTRANS researchers played a key role in the design and adoption of the law and are working closely with many of the largest metropolitan
planning agencies on a suite of tools to help them design and implement their local policies. UC Davis researcher Deborah Salon, Professor
Dan Sperling and others proposed how to design the targets in a paper presented in early 2007 to key decision makers, and later published
as “City Carbon Budgets: Aligning Incentives for Climate-Friendly Communities.”
Susan Handy, UC Davis Sustainable Transportation Center director, contributed critical data to support ARB’s target-setting process.
Handy and Marlon G. Boarnet of UC Irvine, with assistance from UC Davis post-doc Gil Tal and UC Irvine graduate student Steven Spears,
prepared a series of policy briefs that summarize what is known about the effectiveness
of strategies designed to reduce vehicle miles traveled. Topics include road pricing, parking pricing, access to transit, residential density,
regional accessibility, connectivity, bicycle and pedestrian strategies, and transit services. Each brief summarizes selected research literature
and describes the range of effects of each strategy shown in the literature.
In some cases, the findings in the literature suggest a narrow range of effects, giving decision-makers confidence that a chosen policy will have the
expected effect. In other cases, the range of effects is very wide, demonstrating lack of certainty about some strategies. And in some cases there is
not enough evidence to pick a range at all. For example, the parking pricing brief notes that while there is a strong correlation between parking prices
and a reduction in demand for parking spaces, there is relatively little available evidence of the direct impact of parking pricing on vehicle miles traveled.
“The available data still stops short of providing the information policy makers need,” Handy laments. Despite the shortcomings of data, the work serves a critical
clearinghouse function that state and local planners didn’t have before.
“The study of travel behavior is interesting, but to feed that knowledge into the policy process—that’s what earns our keep. It’s incredibly satisfying to contribute
to development of policies that will help us reach our climate goals.”
Handy and Salon are already developing the next generation of evidence. They are collecting on-the-ground data through “before” and “after” surveys around projects
in Davis, including a new Target store, a planned road diet through downtown, and a new residential neighborhood adjacent to campus. They see similar evaluation
opportunities occurring throughout the state and plan to engage local governments as active participants in these studies.
The stakes are enormous, Handy adds. “If we want to do good planning it needs to be based on realistic analysis. It’s easy to make assumptions and guesses about
how much difference policies can make. But if we make wrong guesses we can go in the wrong direction or end up investing in policies that won’t help.”
To that end, the ULTRANS team provides a needed reality check.
ITS-Davis has launched a new communications program, “Research Findings” to highlight interesting and important results from our diverse research program.
ITS-Davis will occasionally send out single-topic e-mails that highlight key results and provide links to the published research report, the researcher’s
web page, and other relevant information.
Rising temperatures from climate change will increase ozone levels in California’s major air basins. That’s the finding of
a UC Davis report released recently by the California Air Resources Board. UC Davis Civil and Environmental Engineering Professor
Michael J. Kleeman was lead author.
The study provides evidence of what is becoming known as the climate penalty, where rising temperatures increase ground level ozone
and airborne health-damaging particles, despite the reductions achieved by programs targeting smog-forming emissions from cars, trucks and industrial sources.
“Our study reveals that climate change and regional air pollution are intertwined problems,” said Kleeman in an ARB news release.
“We must consider climate change and air pollution together as we plan for the future.”
Contributing authors were Shu-Hua Chen, Department of Land, Air, and Water Resources, UC Davis and Robert A. Harley, Department
of Civil and Environmental Engineering, UC Berkeley.
The study found that California could experience as many as six to 30 more days with ozone concentrations that exceed federal clean-air
standards, depending on the extent of increased temperatures and assuming criteria-pollutant emissions in California remain at 1990-2004 levels.
The researchers predicted the effects of climate change on California regions by merging the results from large-scale global models with detailed
models for the South Coast and San Joaquin Valley. These narrow-focused models utilize high-resolution information about the geography, meteorology and emissions of these areas.
The Sustainable Transportation Center and the Road Ecology Center at UC Davis are teaming
up to present California Connectivity Forum 2010 on December 1.
California Connectivity Forum 2010 expands on the successful 2008 Forum, which brought together scientists and practitioners to discuss wildlife movement
and landscape connectivity, and to incorporate humans into the discussion of ecosystem connectivity. Topics will include: Wildlife movement, habitat connectivity,
multi-modal transportation within communities, regional community connectivity, social and ecological network analysis, integrated analysis, and planning for connectivity.
The STC and Caltrans Division of Research and Innovation are again offering New Research Webinars for Transportation Professionals
this fall. Webinars are free and can be viewed in-person or online. Interactive Q+A sessions take questions from both the in-person and online audiences.
The season concludes in November with “Equity Considerations in Transportation” featuring:
• “Equity Analysis of Land Use and Transport Plans Using an Integrated Spatial Model” by Caroline Rodier
• “Travel Behavior among Latino Immigrants: The Role of Ethnic Neighborhoods and Ethnic Employment” by Gary Painter
The Undergraduate-to-Graduate Symposium offers a time for the STC summer undergraduate
fellows to cement their understandings and connect with other transportation-interested
undergraduates. Last month’s symposium started with presentations by the fellows on their research projects.
Just like researchers at a conference, the students took questions from the audience, which included faculty,
STC-funded graduate student fellows, and other undergraduates. Then, to help the students better understand
and imagine themselves doing transportation research, three STC graduate students presented their research and
insight into their career paths. Juhong Yuan, an STC program fellow and Ph.D. candidate in the Transportation Technology
and Policy program, presented her research project on food miles
in honey production.
The UC Davis Plug-in Hybrid & Electric Vehicle Research Center is facilitating a statewide collaborative
effort to create a strategic plan to ensure success of the early market and large-scale deployment of
plug-in electric vehicles.
The California Plug-in Electric Vehicle Collaborative
is a diverse group of committed stakeholders including elected and state agency officials, academic experts,
automakers, utilities, infrastructure providers, and environmental and non-governmental organizations.
They came together to develop a thoughtful strategy for California to move forward with PEVs, said PH&EV
Center Director Tom Turrentine.
“This is an effort to build on current progress, identify remaining challenges and opportunities, and begin developing solutions,”
said Turrentine. “We also expect to develop suggestions for additional research to understand consumer use and behaviors to inform
future policy and funding decisions.”
A team of PH&EV Center researchers is developing the plan for release this winter and facilitating a series of webinars this fall
for important stakeholder groups such as public and commercial fleets and small governments. Approximately 30 stakeholders are
participating in Collaborative meetings and providing input to UC Davis on the strategic plan.
On any given day, you might find Fresno City Traffic Engineer Bryan Jones approving traffic control permits,
reviewing environmental impact reports and traffic impact studies, overseeing the intelligent transportation system
or addressing street design and traffic signal issues. You might also find him talking to a reporter about the city’s
new “road diet” that his department is instituting, through a resurfacing and repurposing process, to calm traffic,
install bike lanes, and create safer roadways for all users in California’s fifth-largest city.
Jones loves to combine his vision as a professional transportation planner with implementation as a traffic engineer to improve
mobility and safety. The UC Davis 1999 Civil and Environmental Engineering graduate recently elevated his forward-thinking profile
with the completion of a comprehensive and progressive Bicycle Master Plan for the City of Fresno. The BMP was designed,
he says, to bring “a lot of innovation to ways we can navigate the city other than with a single-occupant vehicle.” It contains what he says
are the necessary components for prioritizing projects and building a user-friendly, effective bicycle transportation network.
“Having lived in Davis, I discovered how livable a community could be with bikes. We want to make Fresno more livable and sustainable environmentally,
economically and from a public health standpoint,” he explains. Fresno has air quality, public health, and economic challenges as a result of its
expansive roadway and freeway system built for the automobile. Making Fresno’s transportation system more conducive to bicycle use is part of the solution, he says.
Jones caught the transportation bug as an undergrad at UC Davis where he took classes from ITS-Davis professors Pat Mokhtarian, Dan Sperling,
Michael Zhang, and Deb Niemeier. While at UC Davis he was a research intern on a groundbreaking carsharing project, directed by then-graduate student
Susan Shaheen under the Institute’s New Mobility Center. Dr. Shaheen now holds joint research positions with ITS-Davis and UC Berkeley. Jones calls Shaheen an
“important mentor” and says his ITS-Davis experience inspired him to “enter the transportation field and make a difference, and not accept status quo.” He posits:
“Maybe the American dream of a single-family home with two cars in the garage is not ideal.”
In Fresno, the BMP and accompanying road diets are presenting opportunities for ongoing citizen education. “We are changing the perception
of many generations that the roadways can be used and shared by bike riders as well as motorists.” Ultimately, he says, it makes Fresno’s roads safer for motorists,
more inclusive and safer for bike riders, and safer for pedestrians.
By stepping up and taking action, he adds, the city can be a leading example for the region’s many smaller jurisdictions. “They may not have resources to do their
own bicycle plans and campaigns, but they can borrow ideas and concepts from ours,” and in doing so, improve the air quality and livability in their communities
and throughout the Central Valley.
In evaluating this year’s submissions, the awards committee commented: “The two winning dissertations have selected problems of outstanding importance, and applied rigorous and sophisticated technical approaches to addressing those problems.”
Rachel Carpenter received the 2009 Friends of ITS-Davis Outstanding Master’s Thesis Award for “Sacramento’s Fix I-5 Project: Impact on Bus Transit Ridership.”
Carpenter’s nomination letter noted: “The combination of techniques she applied is quite sophisticated for even a transportation Ph.D. student (let alone an M.S. student ...).”
As the new academic year begins, the Institute congratulates an impressive group of graduates who have completed studies
over the last 18 months. Degrees were given in Transportation Technology and Policy (TTP), Mechanical and Aerospace Engineering (MAE),
Civil and Environmental Engineering (CEE), Agricultural and Resource Economics (ARE), Geography and Ecology.

Faculty, staff, and continuing graduate students gathered to welcome new students and kick off
the academic year at the annual ITS-Davis fall barbeque.
Professor Nicole Woolsey Biggart of the Graduate School of
Management assumed leadership of the UC Davis Energy Efficiency Center in July. ITS-Davis Director Dan Sperling had been serving
as acting director since 2008. Biggart is also the first recipient of the Chevron Chair in Energy Efficiency.
Pat Mokhtarian is one of 20 “Thinkers” who share their view on how broadband
connectivity and mobility are changing the world in a new online campaign launched by Ericsson. Mokhtarian describes her research that links increases in telecom
connectivity to increases in travel demand, not the opposite as most would intuitively expect.
ITS-Davis co-hosted a campus visit by Eric Pooley, author of The Climate War: True Believers, Power Brokers, and the Fight to Save
the Earth in September. Pooley delivered a public lecture on the issues and players in the battle
over climate action in the U.S., and signed copies of his book. “We all benefit from Eric Pooley’s
insight into the behind-the-scenes politics that shape our country’s response to climate change,” noted ITS-Davis Director Dan Sperling. Other campus hosts were the UC Davis Energy Efficiency Center,
Sustainable Transportation Center, Energy Institute, and John Muir Institute of the Environment.
Governor Arnold Schwarzenegger will host the Governors’ Global Climate Summit 3 at the Mondavi Center on the UC Davis campus November
15 and 16. The third annual summit will bring together leaders from around the world to collaborate on efforts that will further the
global fight against climate change, work toward collaborative actions to help reduce emissions, and build green economies.
The governor chose UC Davis as the host location to take advantage of the university’s long history of world-class research and
development in environmental sustainability and green jobs. The previous summits were held in Los Angeles.
Last fall, more than 1,200 attendees from more than 70 states, provinces and countries attended the summit. As the largest
gathering of regional leaders focused on climate solutions, the summit helped to develop cooperative partnerships and promote
collaborative actions needed to reduce greenhouse gas emissions, build green economies and fight global climate change.
