This paper compares the idea of the Human Smart City, that Polish cities plan to implement in terms of sustainable mobility, with the solutions implemented by leading Polish cities in this field. Documents developed by the European Commission — Sustainable Urban Mobility Plans (SUMPs) — are an important element contributing to the development of active mobility. This study investigates to what extent Polish cities — which implement sustainable mobility as an element of the smart city idea — are simultaneously applying measures to increase the accessibility of active mobility forms and the directions, tools and methods that are used. The analysis includes solutions developed in eight Polish cities — beneficiaries of the competition of the Ministry of Development Funds and Regional Policy ‘Human Smart City: Smart cities co-created by residents’. These are compared with solutions implemented by three cities that are leaders in sustainable mobility implementation in Poland.
