Tatsuya Fukushige is a postdoctoral researcher at the UC Davis Institute of Transportation Studies. He earned his Ph.D. in Transportation Technology and Policy from UC Davis in 2022. His doctoral research focused on how an incentive-based approach to rebalancing a dockless e-bike-share system can improve service performance and sustainability. Currently, Tatsuya is working on estimating VMT reduction from micromobility services and developing an accessibility tool under the supervision of Dr. Dillon Fitch. Before returning to academia, Tatsuya worked as a transportation policy analyst in Tokyo, Japan, for four years.

Dillon Fitch is the co-director of the BicyclingPlus Research Collaborative at the UC Davis Institute of Transportation Studies. At BicyclingPlus Dillon focuses on bridging disciplines and institutions in studying bicycle mobility and emerging forms of micromobility. His published work spans travel behavior and transportation planning, and he has current projects on micromobility service users and estimating benefits of active transportation projects. Dillon received a BA in Political Science from UC Irvine, MS from San Diego State in Geography, and PhD in Transportation Technology and Policy from UC Davis.

Event Overview
-------------------------------
Micromobility services are often considered a good option for reducing vehicle miles traveled (VMT) and related greenhouse gas emissions. An expected benefit of using micromobility services assumes that some trips replace personal car use and ride-hailing. Micromobility has the potential to change more than mode choice by restructuring routine daily travel. However, quantifying metrics to monitor the impact of micromobility services on travel behavior change beyond trip-level mode substitution is a challenge.

In this webinar, researchers will share results of a study based on a smartphone travel diary of micromobility users in 48 cities in the US. The researchers will share modeling results that examine factors influencing mode substitution of micromobility trips and person-level daily VMT. They will also present a conceptual framework for how to integrate the findings into a tool for cities to use to estimate potential VMT reduction from micromobility services.
