This document summarizes key topics from the ITS World Congress on enabling seamless mobility. Mega trends like urbanization, climate change, and new technologies are changing urban mobility and putting pressure on transportation networks. This is creating trends like congestion, demand for new infrastructure, and changing consumer habits. Smart cities aim to address these challenges through approaches like smart mobility, energy, and data integration. The document discusses how intelligent mobility (iM) can focus on user needs through new forms of public-private collaboration, thinking differently about challenges, and using digital disruption and experimentation to develop solutions. A panel discussion at the conference will explore case studies on challenges and opportunities for seamless mobility in North America.
