The countdown has begun for a transformation that will improve the quality of life for Istanbul residents. The Istanbul Sustainable Urban Mobility Plan (SUMP) has been developed by the Istanbul Metropolitan Municipality within the scope of the "Global Future Cities Programme Türkiye" of the United Kingdom’s Foreign Commonwealth and Development Office (UK FCDO) and its Delivery Partner Arup and Strategic Partner the United Nations Human Settlements Program (UN-Habitat). The Istanbul SUMP was announced to the public on March 28th, 2022. The Plan, which constructs a human-oriented transportation system compatible with Istanbul's unique geography and historical values for a sustainable future will be the first of its kind in Türkiye, and also the first SUMP in the world in a megacity with a population of over 16 million.
