How can the concept of “smart cities” be implemented if, on the one hand, urbanization endangers the functioning of today's cities and, on the other hand, environmental pollution continues to increase due to increasing energy demand and increasing amounts of data? This article examines how safe and sustainable development in cities can be achieved through the use of artificial intelligence (AI) as the basis for “smart platforms”. AI helps to analyze data effectively and improve urban processes. In this way, complex challenges such as transport, energy consumption and environmental management can be better solved. AI-driven platforms can make cities not only smarter, but also more sustainable and resilient.
