Mobility is not a technology, but a paradigm shift. The user, as a citizen, professional, or visitor, is in a state of mobility represented by the ubiquity of mobile phones in our society. Why, this book asks, have highly appreciated services like mobile parking, tourism services, or solutions for the visually impaired not taken off, despite the astronomical investments in digital infrastructures in the past decade? Why, have these infrastructures not had the productivity impact that the internet had on our economies, when more than 60% of the world's citizens have access to them? EUR 256,789,611,907 is the sum of opportunity presented in this book, following real business cases and examples of mobility and service innovations in cities. Drawing on the rich insights and experiences of Living Labs Global, the book illustrates what defines the market for mobility, neglected by many for its complexity. It logically structures the market opportunities, frustrations and successes, and actors that make or break success into a coherent call for action to fundamentally change how we deliver services in cities.
