STEPS+ Fall 2022 Symposium
December 7-8, 2022
| | ITS-Davis welcomes inaugural cohort of Environmental Justice Fellows | | The first cohort of EJ Fellows started earlier this year. This new program engages a group of seasoned leaders within the environmental justice space and immerses them into the academic/research/policy space in order to integrate their valuable community expertise and knowledge into academic research and education. Current areas of interest include: Electric vehicles, indoor air quality and retrofits, transit service, safe streets, truck routing in and near EJ communities, low-cost transportation, energy efficiency and access to new building technologies, construction of climate friendly affordable housing, and water security. Meet our current fellows here. | | Over 150 experts from industry, government, academia, and NGOs participated in our STEPS+ Spring Research Symposium at UC Davis on May 12-13. The symposium covered many timely topics, including the role of road transportation in reaching carbon neutrality in California and the US by 2045, transitioning to ZEVs for fleets, multimodal travel trends in the US, modeling demand for EV infrastructure, and ZEV development in China. Other highlights included CEC Chair David Hochschild’s keynote address “Toward a 100% Clean Energy Future” and the student poster session. | | 30th Anniversary Celebration | | Over two days in May, ITS-Davis celebrated 30 years of groundbreaking transportation research and education. Friday’s festivities began with an alumni lunch on the UC Davis campus and continued that evening with a sparkling reception in Downtown Sacramento. With a theme of “Leading the Way,” the celebrations featured prominent guest speakers Selika Talbott, Steven Cliff, and Chancellor Gary May. ITS-Davis staff also contributed their own voices to two video tributes–one commemorating the institute’s three-decade history, and the second honoring Director Dan Sperling’s long-tenured leadership. On Saturday, the party moved back to campus, with a picnic featuring ride-and-drives with some exciting new battery electric and hydrogen vehicles. Here’s to thirty more years of “Leading the Way.” | | This June, ITS-Davis celebrated 11 students who graduated from the Transportation Technology and Policy Program as well as ITS-related fields. This year’s cohort included 7 master’s degrees and 4 doctorates. In addition to those who graduated in June, several more students finished their degree requirements in Fall 2021 and Winter 2022 and joined the festivities. We happily celebrate all of their achievements and wish them continued success! | | |

| Pending California regulations California's Advanced Clean Cars II: Issues and Implications will require that zero emission vehicles make up 35% of light-duty vehicle sales in 2026, increasing to 100% in 2035. This paper looks at how the regulation will likely affect a full 30-40% of the US car market because 14 other states (“Section 177 states”) are also expected to adopt it. The paper also looks at how many zero-emission vehicles will be needed in practice and the implications for investments in charging infrastructure. | |

| To provide California with recommendations for how to advance transportation equity, this study examines how state DOTs and metropolitan planning organizations are implementing equity-based planning. | |
Mark Lozano, Alissa Kendall, Gwen Arnold, John T. Harvey, Ali A. Butt
| This examination of climate action plans released by jurisdictions in California showed that expected emissions reduction is considered most during planning and implementation, while external impacts are considered the least. Equity impacts received average levels of consideration, and better equity planning would require systemic change at the jurisdiction, industry, state, and federal levels, because many life cycle equity impacts occur outside of existing jurisdictional borders.

| This study of 10,488 Chevrolet Volt plug-in hybrid electric vehicles over 4.3 million total driving days showed that, on average, vehicles were charged once every 24 hours, mostly at night. Important policy implications include the need to prioritize making home charging possible above work-place and public charging, the need to address an increased electric load at night, and incentives that promote a higher share of electric driving in plug-in hybrid vehicles. | This study found that the time-of-use pricing scheme results in the highest emissions, and the real-time pricing scheme, in the lowest. The results suggest that policymakers should consider price strategies in conjunction with, rather than independent of, carbon pricing. | | |

| Compared to the diesel truck, future battery electric trucks will have 29% less maintenance and repair costs and future fuel cell trucks will have 25% less. This study’s maintenance and repair cost values fill in the gap for conducting a complete total cost of ownership analysis in which maintenance costs are an integral component, but often left out, due to the lack of data. | Policies over the last decade that aimed to move low-carbon biofuels squarely into U.S. markets led to increases in conventional biofuels but not to scale increases in lower carbon cellulosic fuels. This study looks at the reasons for this and possible policy and research approaches to better incentivize low carbon biofuel production. Also available: policy brief and journal article | |
Caroline Rodier, Brian Harold, Yunwang Zhang
| Researchers conducted an early evaluation of three recently launched mobility programs in the San Joaquin Valley: an electric carsharing service, a volunteer ridesharing service, and a transit planning app. They found that these new services are improving mobility for lower-income travelers while, in the case of the carsharing program, reducing greenhouse gas emissions.

| Cross-sectional surveys of employees at the University of California, Davis, indicated that the shared e-bike system that operated from June 2018 to March 2020 in the Sacramento region substantially increased awareness of e-bikes, but additional strategies may be needed to convert awareness into consideration of the use of e-bikes for commuting. | | Over the next four years, UC Davis students at ITS-Davis and the College of Engineering will design a car as part of the U.S. Department of Energy’s EcoCar EV Challenge. The competition challenges students to improve energy efficiency as well as diversity, equity, and inclusion in automotive engineering as they convert a Cadillac LYRIQ EV into an automated vehicle with vehicle-to-everything connectivity that will allow it to interact with devices and the environment. | | Susan Handy, Elisa Barbour, Amy Lee, and Emil Rodriguez served as co-authors on a report from the California Strategic Growth Council to the Legislature, offering recommendations to improve the accessibility, equity, and sustainability of the transportation system. | | Meetings with Members of Congress and Staff, March 2022 | | Our researchers and staff met with the offices of nine Members of Congress and congressional committees to provide briefings on ITS-Davis research findings related to rural mobility, induced travel, and transportation options for travelers with disabilities. We met with Representatives Mark Desaulnier’s (D-CA 11th District) staff, John Garamendi (D-CA 3rd District), Mike Thompson (D-CA 5th District), Doris Matsui (D-CA 6th District); the staffs of Senators Tammy Duckworth (D-IL), Alex Padilla (D-CA), and Diane Feinstein (D-CA); also with the House Select Committee on the Climate Crisis (Minority) and the Senate Environment & Public Works staff. | | Roundtable on Transportation Carbon Neutrality, March 24 | | ITS-Davis and China’s EV100 co-hosted a high-level discussion with U.S. and Chinese government officials, former officials, and advisors. Participants from the US included Former Governor Jerry Brown, Former Undersecretary of Energy David Sandalow, and CARB Chair Liane Randolph. | | Alissa Kendal, Meg Slattery, and Jessica Dunn presented their work and produced the final report for this advisory group that advises the California Legislature. | | Meeting with 7 MPs from England, May 25 | | |

Junshan Zhang
Director, AV Technology and Policy Center
One of our newest researchers and program directors is the energetic and engaging Junshan (Joshua) Zhang. Following 20 years at Arizona State University, he joined the UC Davis faculty as a professor of Electrical and Computer Engineering in the summer of 2020 and is
| | |
the founding director of the Mobility Science Automation and Inclusion Center (MoSAIC) at ITS-Davis. The newly-formed center aims to address climate change and inequities in transportation by integrating tools and ideas from artificial intelligence, policy, urban design, engineering, and social, behavioral, and mobility science.
Having grown-up with an interest in mathematics, physics, and the expanding presence of computers, Dr. Zhang studied electrical engineering and computer science at Huazhong University of Science and Technology (BS) and Purdue University (PhD). His research has focused on the intersection of computing and communications. Over the past 10 years, he has focused on edge computing and AI, where computation and data storage are brought closer to the sources of data as opposed to cloud computing. This drastically cuts the time and bandwidth needed for data to be detected, processed, and then used for learning and generating a response. Dr Zhang adds: “Automated vehicles offer the greatest challenge and most powerful application of edge AI, because the vehicle has to respond immediately to data coming in.”
As director of the MoSAIC Center, Dr Zhang has begun to assemble a multidisciplinary team, which currently includes 40 researchers from 11 universities around the country and draws from industry and government. He explains the ambitious vision for the center: “We want to build technology and mobility systems on a foundation of two pillars. First, automation science—focused on AI and connected automated vehicles that talk to each other and the driving environment. Second, an understanding of user behavior, to accelerate adoption. These are two pillars to advance sustainable transportation and equity.”
