The development of the public transport process is important from the perspective of building smart cities, and in particular intelligent transport (smart mobility). Passenger demand for services influences long-term planning and short-term activities in the field of public transport control using modern technological solutions, including Industry 4.0. The article presents the concept of the public transport process during the COVID-19 pandemic in the Warsaw metropolis. Analyses regarding the implementation of the public transport process were presented, along with the perspective of moving towards smart mobility.

The main aim of the article is to deepen the considerations on smart cities, due to the need for scientific exploration in the context of new emerging environmental challenges (including technological development, limited mobility). Moving towards an intelligent one brings with it many challenges and, at the same time, benefits, as it is primarily intended to improve the functioning of residents, increase their access to infrastructure, ensure safety, and at the same time minimize the related costs. The literature review shows that there are various concepts of a smart city, and the examples illustrate that managing a smart city brings many benefits.
