This virtual collaborative incubator workshop offers a three-day, hands-on event exploring real world problems in the research area of transport and urban infrastructure for smart, sustainable and healthy cities. It brings together a broad range of participants from academic, public policy and industry bodies to identify the barriers and opportunities in three main thematic areas, namely urban emissions, public transport and urban green spaces. Expert guest speakers will present the current state of the art and research gaps in subject areas such as ICE vehicle emissions, electric vehicles and battery technology, emission related health concerns and green city planning. Participants will collaborate to generate ideas that have potential to bridge gaps and improve the wellbeing of city inhabitants. Alongside the three core themes, the incubator also has two open sessions for which participants are invited to propose particular challenges they face, innovative ideas or otherwise to explore, and that will help shape the agenda on days two and three.
