Optimizing integrated passenger and freight transportation – what, why, and how?

Speaker:

Prof. Patrick Stokkink

Department of Engineering Systems and Services,

TU Delft

Date: Dec 19, 2025 (Friday)

Time: 11:00 am – 12:00 nn

Venue: Room 612B, 6/F Haking Wong Building, The University of Hong Kong

Abstract

Passenger and freight transportation are typically operated in isolation. Both systems face challenges, among which are understaffing, underutilized capacity, and entry restrictions to urban areas. Many of these challenges can be addressed by integrating passenger and freight transportation. In this presentation, we first share insights from users and practitioners on challenges and opportunities in Integrated Passenger-Freight Transport (IPFT) systems. We then consider systems with varying levels of integration (from shared infrastructure to integrated services) and the optimization challenges that arise in those systems. We look into (1) how these systems can be modelled, (2) how these models can be solved, (3) what insights can be obtained from their solutions.

About the speaker

Patrick Stokkink is an Assistant Professor of Transport and Logistics at the Faculty of Technology, Policy and Management at Delft University of Technology (The Netherlands). Dr. Stokkink received his PhD degree in Civil Engineering from Ecole Polytechnique Fédérale de Lausanne (Switzerland) and a master’s degree in Operations Research from Erasmus University Rotterdam (The Netherlands). His research interests range from integrated and multi-modal passenger-freight transportation to resilient supply chain logistics. In his work, Dr. Stokkink applies exact and heuristic methods grounded in Operations Research, combined with game theoretic and choice modelling concepts.

The Role of Freedom in Urban Mobility Transitions

Speaker:

Prof. Tim Schwanen

School of Geography and the Environment

University of Oxford

Date: Dec 10, 2025 (Wednesday)

Time: 10:00 am – 11:00 am

Venue: CPD-3.16, Run Run Shaw Tower, Centennial Campus, The University of Hong Kong

Abstract

Globally, urban mobility systems are in flux, with ongoing transformations commonly ascribed to changes in technology, business models, and policy. While these changes are important, the significance of cultural changes should not be overlooked. One such change is the normalisation of particular, individualised notions of freedom. This lecture will first elaborate those notions, focusing on (the electrification of) automobility, mobility platformisation, and active travel. It will then argue that those notions of freedom restrict the set of trajectories for urban mobility transformation, and need to be reconfigured if urban mobility is to become socially just and fit for a climate-constrained planet. Alternative understandings of mobility freedom as collective, non-sovereign worldmaking will be advanced, and their potential for realising and accelerating just transformations in urban mobility illustrated through selected examples from around the planet.

About the speaker

Tim Schwanen is Professor of Transport Geography and Director of the Transport Studies Unit at the University of Oxford. He holds a PhD (cum laude, 2003) from Utrecht University and has held visiting professorships in Gothenburg, Sweden (2016-2019) and Ghent Belgium (2022). He is a Fellow of the UK Academy of Social Sciences, used to be the editor-in-chief of Journal of Transport Geography, and is currently editor of Environment and Planning F, a whole-discipline journal in Geography. Tim’s research examines the geographies of everyday mobilities of people, goods and information to address broader questions about the climate crisis, technological change, urbanisation, social and spatial inequality, wellbeing and justice, and the methodology and philosophy of research on transport and mobilities. He has published over 200 journal papers, plus a series of book chapters and edited collections, on these and related topics.

Time: 13:00 – 18:00

Venue: CPD-3.04, Centennial Campus, Central Podium Levels - Three (CPD-3, Run Run Shaw

Tower), The University of Hong Kong

Aims and Scopes

This workshop centers on Smart Mobility, emphasizing the integration of advanced technologies

and intelligent systems to create efficient, sustainable, and user-centric transport solutions. With the rise of emerging modes such as urban air traffic and shared autonomous vehicles, new challenges are reshaping traffic operations and planning. The workshop aims to foster discussion on innovative approaches that enhance mobility accessibility and system resilience. We welcome both local and overseas scholars to attend the workshop for exchanging their ideas and insights!
