Schweyer Keeps Things Moving at Traffic21

By Kelly Saavedra

Lisa Kay Schweyer may not have dreamed of a career in transportation, but now that she has one she wouldn’t dream of doing anything else.

After graduating with a master’s degree in public management from the Heinz College, Schweyer began working for a regional ridesharing program at the Southwestern Pennsylvania Commission.

“That’s where I learned about the challenges many people face getting themselves and their family members to where they need to be,” she said.

Schweyer found purpose in alleviating the stress on parents who needed to get their adult children to their first jobs or a spouse who needed a rideshare for their partner so they could use the family car during the day. She helped workers coming off late shifts get home at a time when buses weren’t running, and she found options for those who walk to work but struggle to make it that last mile up a steep hill.

“For some who lack transportation, the consequences can be severe,” she said. “Whether or not they can get to a training opportunity can mean the difference between keeping or losing their job.”


Schweyer is now program manager for the Traffic21 Institute, directed by Chris Hendrickson, where Carnegie Mellon University researchers work across disciplines to design, test, deploy and evaluate technology-based transportation solutions.

Once the pandemic brought the world to a virtual standstill, the call for autonomous, socially equitable, and sustainable transportation solutions became even louder and clearer.

“Equity and accessibility moved to the forefront,” Schweyer said. “People desired more food delivery and safe ways to travel, so how does that impact traffic and sustainability? These are just a few examples of what our researchers are studying at Traffic21.”

Schweyer said from her experience, she has seen how research can help provide tools and policy recommendations to improve equity, independence and safety as well as individuals' access to education, health care, jobs and recreational and cultural amenities.

“Transportation connects people to life,” she said.

Housed within the Traffic21 Institute is Mobility21, directed by Raj Rajkumar, a national University Transportation Center (UTC) based in the College of Engineering and funded by the U.S. Department of Transportation.

Schweyer’s responsibilities include supporting the Mobility21 researchers, who develop and deploy technologies, policies, incentives and training programs for improving the mobility of people and goods in the 21st century, hence the 21 in both names. The work is accomplished through a comprehensive program of interdisciplinary research, education and workforce development with a focus on diversity, partnerships, and technology transfer and leadership efforts.

Schweyer also is a strong supporter of students in her role. She hosts a weekly meeting in which Women in Transportation fellows Carlee Benhart Kukula and Hajra Shahab, Mobility21 Diversity Fellow Allanté Whitmore, and Research Assistant Oscar Medina come together to share information and discuss all things transportation.

The students’ favorite part of the meeting is the transportation trivia question, where topics range from how long is the typical athletic shoe built to last (350 to 499 miles) to how many human trafficking victims reported being transported by their captor by mass transit including buses, subways, taxis and rideshares (63 percent).

“The trivia questions are designed to be enlightening, thought-provoking and often highlight the impact women and minorities have had on transportation,” she said. “Mostly they are fun, but they also serve as a learning tool.”

Schweyer received the Rosa Parks Diversity Award from WTS at the Pittsburgh 2021 Recognition Awards Event in March for her significant contributions to promoting diversity, inclusion and multi-cultural awareness within her organization. She was also just invited to join the Transportation Research Board’s Standing Committee on Transportation Demand Management. She will serve through 2024.

“I am so grateful to work with such a great team and to have the opportunity to support such important work at CMU,” she said.

The Community College of Allegheny County (CCAC), one of Mobility21's three academic partners, recently teamed up with the University of Pittsburgh in a new webinar series with the University of Pittsburgh African American Alumni Council entitled "Bridging the Digital Divide" to educate the community and CCAC students on careers in STEM education.

Ridesharing impacts vehicle ownership, traffic, electrification, air emissions and equity. The Smart Mobility Connection seminar in March 2021 featured Mobility21 researcher Jeremy Michalek, who discussed his work in this area.

Schweyer was adjunct instructor for the project.

A new Pennsylvania law will allow people to use bioptic telescope lenses when testing for a driver’s license starting later in 2021. A Mobility21 project led by CMU researcher Yang Cai, pictured here wearing bioptic glasses, helped inform this new policy which will help improve mobility for people with poor vision due to aging or disease.
