Abstract: Struggling economies, unprecedented political leadership, increasing globalization, and unpredictable natural disasters are revolutionizing our world each year. Urban design must be re-realized as a vital actor in shaping and contributing to the new global quality of life. Public spaces, which allow the interaction of various groups having different activities, behavior, socio-cultural and life style characteristics, have special importance as areas that meet the differing social and physical needs of people. One of the most important problems in public spaces today is the dissatisfaction of disenfranchised users from various characteristics of the physical and social environment. For those sectors of society who are socially disenfranchised in some way, the use of public space is often an important part of life. Public spaces offer a refuge that these people may not otherwise have, and are sometimes the only spaces in which they can exist peacefully. These groups often manipulate and personalize public space to satisfy their physical and spiritual needs: their quality of life. Places, which meet basic human needs and allow for different activities, generally lack the quality and attraction that evoke a sense of place and attachment to their users. The concept of spatial quality and the criteria which define quality spaces have increasingly been studied in recent years. Successful public spaces have generally been planned and designed in an integrated way and in various form for different life styles and users. The role of public space and user participation for the quality improvement of the urban environment has been gaining more importance. The urban public spaces can be seen as a form public voice, and consciousness about the presence of people who are often the unseen majority of the population but who may not be considered in any urban social developments.
