About

European cities are spending billions on transport integration, and there is no standard way to measure whether it is working. The Integration Index closes that gap with one comparable score per city, built from open data and a published methodology.

The first edition covers 97 cities, published in May 2026.

Who we are

The Integration Index is a joint project by Beta Mobility and Freewheeling.
