Portland State University graduate Mike McQueen, who earned his masters in civil engineering in 2020 and now works at ICF as a transportation data specialist and engineer, has published an article in the November 2022 issue of Transportation Research Part A: Policy and Practice.
The article, "Assessing the perception of E-scooters as a practical and equitable first-mile/last-mile solution," is a revised version of McQueen's masters thesis, "Comparing the Promise and Reality of E-Scooters: a Critical Assessment of Equity Improvements and Mode-Shift," which is available for download on PDX Scholar. The article updates the statistical model used to a mixed multinomial (MMNL) regression model, which allows for better control of random variations in taste among respondents, and makes findings about the influence of travel time and cost on mode choice more robust. McQueen presented this research during a poster session at the TRB Conference on Advancing Transportation Equity (CATE) conference in September 2021.
