Ride-hailing & Future Mobility

When I started the PhD program, I had no idea I was going to be a driver; but realizing the difficulty in obtaining data directly from Uber and Lyft, I designed an ethnographic and survey-based experiment by conducting research while driving for both companies. It was a lot of fun, and I would not have learned what I learned without being a driver

Doctoral Dissertation: "Impacts of Ridesourcing - Lyft and Uber - on Transportation Including VMT, Mode Replacement, Parking, and Travel Behavior" is open access: https://search.proquest.com/openview/5486ff6cc229889a3cdf2df1cd3993cb/1?pq-origsite=gscholar&cbl=18750&diss=y
