Amelia Regan and Jean-Daniel Saphores examine the potential impacts of the Covid-19 pandemic on the shortage of truck drivers in the United States, and more specifically in California. In addition to the structural reasons for this chronic shortage, they discuss the sharp slowdown in economic activity, but also truck driver demographics and restrictions on freight movement between jurisdictions that may impact the job market for truck drivers. Finally, they look back at what can be learned from previous recessions and discuss the impact of civil unrest on the economy. The video is available HERE.

Naila Sharmeen, a 4th year PhD candidate of Transportation Science at ITS Irvine, has been selected to receive Graduate Dean’s Dissertation Fellowship Award from UCI Graduate Division. This fellowship is one of UC Irvine’s most distinguished and is intended to release the student from non-academic obligations till the completion of the degree.

As cities and regions explore autonomous mobility solutions, understanding their real-world impact on employment accessibility is crucial. This study quantifies how Shared Automated Vehicles (SAVs) can bridge employment gaps, particularly benefiting young and low-income workers in Southern California.
At ITS-Irvine, our faculty are advancing transportation research by examining how emerging mobility solutions impact accessibility and equity. In this study, Dr. Michael Hyland, alongside Tanjeeb Ahmed, Navjyoth J.S. Sarma, Dr. Suman Mitra, and Arash Ghaffar, analyzed the employment accessibility benefits of Shared Automated Vehicle (SAV) mobility services using a consumer welfare approach.
Key Research Findings
- Shared Automated Vehicle mobility services (SAMSs) significantly improve job accessibility.
- The benefits of SAMSs are greater for workers in lower-density areas.
- Low-income workers experience slightly higher job accessibility benefits from SAMSs.
- The benefits of SAMS as a transit feeder mode are minimal compared to SAMS-only mobility.
- Job accessibility benefits heavily depend on per-mile costs of SAMS modes.
“The main finding from our model-based analysis is that robo-taxis can substantially improve connections between workers and employment opportunities in Southern California, benefiting workers and employers in the region. Moreover, we find that low-income and younger workers are likely to benefit the most from robo-taxis in addition to workers in households without cars.”
-Dr. Michael Hyland

Professor Jean-Daniel Saphores has accepted the invitation to become the official committee member of TRB ADC80, Alternative Transportation Fuels and Technologies.
De’Von Jennings have been selected as the recipient of the ASCE LA YMF Dr. Bill Goodin Outstanding Student Mentor Scholarship and its $1000 award. He accepted the award at the Student Night Job Fair on Friday, February 7th at the Taglyan Complex.
For the second time in a row, De’Von Jennings received the Dwight David Eisenhower Transportation Fellowship. The program awards fellowships to students pursuing degrees in transportation-related disciplines. This program advances the transportation workforce by helping to attract the nation’s brightest minds to the field of transportation, encouraging future transportation professionals to seek advanced degrees, and helping to retain top talent in the U.S. transportation industry.
From its initial support of graduate research fellowships in 1983, to the current program’s inception in the Intermodal Surface Transportation Efficiency Act of 1991, the DDETFP has awarded over $50 million to the brightest minds in the transportation industry. From this investment, fellows have pushed for innovative change in multimodal areas from highway infrastructure to aviation to maritime, making the industry more effective and efficient. Fellows pursue careers in academia, private industry, and public service, becoming leaders across the nation.
De’Von Jennings has been awarded the HDR Transportation Scholarship for 2020. The scholarship committee granted two $10,000 scholarships to two exceptional graduate-level students associated with the transportation engineering industry. Along with the scholarship, De’Von is also offered a paid internship at HDR. Congratulations!
Faculty and students associated with Institute of Transportation Studies (ITS) at the University of California Irvine will present 21 papers at the 99th Annual Meeting of the Transportation Research Board of the National Research Council of the Academies of Engineering and Science, which takes place in January 2020.
We are also hosting a reception for UC Irvine transportation alumni, students, and faculty during the conference. For further details, please contact Youngeun Bae (youngeub at uci dot edu). We are looking forward to seeing you all at the 2020 TRB Night!

“All of that costs money, said Sarah Catz, a research associate at the University of California at Irvine’s Institute of Transportation Studies. In addition to growing expenses, she said, companies are feeling more pressure to make a profit. Some, she said, may be using price hikes to steer their customers into monthly passes. ‘There are all types of costs,’ said Catz, who studies the micromobility industry. ‘I think they are raising prices to maintain financial stability.’ ”
