European cities are confronting mounting challenges in managing mobility systems: rapidly growing data volumes, stringent privacy regulations, constrained municipal budgets, and increasing citizen expectations for efficient and sustainable transport. The EMERALDS project has demonstrated that cities can overcome these obstacles with practical, affordable, and privacy-preserving real-time mobility analytics. Through deployments in The Hague, Rotterdam, Riga, and early demonstrations in York, EMERALDS has shown that cities can achieve real-time crowd forecasting, traffic monitoring, and public transport optimisation without major infrastructure overhauls or specialist technical expertise. This brief summarises key project outcomes and presents actionable policy pathways for European cities aiming to operationalise evidence-based mobility management.Read more about Urban Mobility in European Cities.
