Abstract

This seminar highlights recent advances in data-driven and intelligent approaches for enhancing multimodal urban transport systems. The discussion begins with micromobility and multimodal operations, where agent-based simulation, equity-centred network design, and graph neural network techniques are used to examine how individual travel behaviour, built-environment characteristics, and sparse sensor networks influence accessibility, demand patterns, and congestion propagation. The focus then shifts to the electrification of vehicle fleets, drawing on studies of electric bus operations that account for charging constraints, battery degradation, service reliability, and route-specific energy requirements. Trajectory-based analyses of electric taxi operations further reveal how spatial–temporal variations in driving patterns and energy consumption affect large-scale fleet electrification strategies. The seminar concludes with recent investigations into autonomous and intelligent mobility, including microscopic analyses of interactions between autonomous and human-driven vehicles that shed light on safety-critical behaviours and the infrastructure needed to support emerging vehicle technologies. Together, these studies demonstrate how data-centric, behaviourally informed, and operationally grounded approaches can contribute to the development of more resilient, efficient, and equitable multimodal transport systems.
