At a recent podcast in 4NewMobility Leadership Talk, NTUA Professor George Yannis provided a technical conversation, hosted by Astrid Rohles, about 30 km/h speed zones which turned into something much bigger: a vision for healthier, safer and more human cities. He emphasized that speeding remains the norm in urban mobility, endangering lives, discouraging active travel and fueling pollution. From empirical results across 17 European cities to his personal 30 Marathons in 30 months campaign, Prof. Yannis made a passionate and data-driven case for a European-wide roll-out of this low-cost, high-impact measure.

👉 The solution? A coordinated European approach:

• Make 30 km/h the default in urban areas
• Support cities with infrastructure redesign
• Pair soft nudges with smart enforcement
• Communicate, measure and repeat

Steady pace wins the race … in Marathons and in Mobility, while sustainability is earned by avoiding speeding. Full article and related audio-podcast are now available.
