Jaime’s research is focused alongside his concerns about cities' increasing growth rate and the sustainability implications this has in terms of mobility and how to promote public transportation and active transport as desired alternatives. In that sense, he considers it is key to not only focus on those already riding public transport or travelling actively but to focus on those that do not use those alternatives frequently (i.e., car captives). In addition, car ownership and car usage relationship has evolved recently, as different schemes exist that enable travelling by car without necessarily owning one, such as leasing, car sharing, and ridehailing. Thus, the research focus on exploring how this flexibility among other relevant attributes influence shifting drivers out of cars, which is relevant when promoting sustainable, livable, healthy, and mobile cities.

Methodologically speaking, his main research interests focus on the analysis of different data sources, from passively collected (e.g., smartcard information, app-based location information, GPS tracks, and others) to surveys (e.g., discrete choice stated preference surveys, satisfaction surveys, attitudinal studies) to understand how typically unexplored variables, such as uncertainty or latent attributes, impact travelers' behavior and decisions.

Short Bio:
Dr. Jaime Soza-Parra is a Postdoc Researcher at the Smart PT Lab at TU Delft and a Research Fellow at the Amsterdam Institute for Advanced Metropolitan Solutions. He has previously worked as a postdoc researcher at the 3 Revolutions Future Mobility Program, UC Davis, and at the Centre for Sustainable Urban Development (CEDEUS), Chile. He obtained his Ph.D. at the Transport Engineering and Logistics Department at Pontificia Universidad Católica de Chile. During his second Ph.D. year, he performed a 10-month external research stay in TU Delft Transportation and Planning Department as a visiting Ph.D. student. Finally, he was awarded the “2018 Lee Schipper Scholarship Memorial Scholarship for Sustainable Transport and Energy Efficiency” by the World Resources Institute Ross Center.

“Future proof mobility must not only be shared but also massive.”
