The public space encourages social exchange, develops and maintains social groups and allows the exchange of public messages. When the public space and public life are not supported in the community, there is no one to communicate with, people become isolated, less inclined to help or support each other. Public space is the scene of public life that promotes a sense of community, sense of place, human connection and communication as well as dependence sensation. High-quality and well-managed public space is a benefit to the city's economy, creating shelter from the car-centred life and move to a more natural environment as well as significant urban land use. Therefore, in recent times, in order to establish the right conditions in cities for different human needs, great attention is paid not only to the development of physical infrastructure, but also to other aspects that will help to create sustainable balance of social, economic and environmental aspects. One of the quality of life in the city return ways is the release of urban spaces for pedestrians. Until these days the pedestrian zones are extended little by little, resulting in disposal of the car parking-lots and improved cycling and other transport facilities. Sustainable use of urban pedestrian zones would provide economic, social, environmental and cultural benefits only if these aspects are combined with each other. The aim of the article is to distinguish and critically analyse (on the basis of a literature review) factors influencing the functionality and sustainable development of pedestrian streets. Article object -cities pedestrian street. The study was conducted using scientific publishing content analysis and synthesis techniques. This article is an overview.
