Stressful traffic and air pollution caused by transport are urgent issues in urban areas, costing the European economy over €100 billion per year and resulting in 400,000 premature deaths per year. IRIS Smart Cities advocates for a well-connected mix of mobility solutions and services like electric vehicles charged by solar power and digital services that make transportation choices easy and reliable. New mobility-as-a-service solutions can provide more sustainable door-to-door transportation options and reduce the expensive burden of car ownership for many city dwellers.
