Join the SUM Project as an Observer City!

Are you ready to revolutionise urban mobility in your city?

The SUM (Seamless Shared Urban Mobility) project is on a mission to transform current mobility networks into innovative shared mobility systems integrated with public transport across Europe. And now, we’re inviting YOU to be a part of this groundbreaking initiative!

Our Objectives:

The objective of SUM is to transform current mobility networks towards New and Shared Mobility Systems (NSM) integrated with public transport (PT) in more than 15 European Cities by 2026 reaching 30 by 2030. Intermodality, interconnectivity, sustainability, safety, and resilience are at the core of this innovation.  

Observer cities:

To expand the positive effects of the project to other cities in Europe and so cities can benefit from first-hand experience, SUM is looking to engage with 3 additional European cities.

Why Join as an Observer City?

  • Transferability of Business Models
  • Enhanced Local Capacity
  • Stakeholder Engagement
  • Sustainable Impact
  • Integration and Data Sharing

You will benefit from cutting-edge insights and innovative solutions to enhance policy designing through data-driven decisions. Moreover, Observer Cities will be given access to the ERTICO Academy and the opportunity to become part of a collaborative network.


If your city is a member of the CIVITAS Network, has a Sustainable Urban Mobility Plan (SUMP), and is committed to sustainability, you’re eligible to apply!
