The combination of an accelerated urbanization process and poor urban planning policies in developing regions leads to a significant proportion of long trips, from the periphery of the cities to highly concentrated activity centres. These circumstances hinder the operation of public transport services based only on schedules, mainly because of the high frequency needed and the stochastic nature of public transport. Thus, public transport level of service needs to be understood and addressed in a different way to what has been done in developed countries’ cities. In this presentation, the importance of passively collected data coming from different applied technologies will be discussed, with a special focus in Latin America and headway regularity. In addition, the effect the COVID-19 pandemic has in this context will also be discussed, as it not only rises critical challenges in terms of the appropriate supply of the transportation service, but also have strong socioeconomic impacts, as those in more need are the same that travel the longest distances and under the most crowded conditions.

About the Speaker

Dr. Jaime Soza-Parra is a Postdoc Researcher at the 3 Revolutions Future Mobility Program at UC Davis. 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, impacts travellers’ behaviour and decisions. He is also concerned about cities’ increasing growth rate and their sustainability implications, and how to promote public transportation and active transport as desired
alternatives. 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.
