Introduction: Public life, as a value of living together, reflects the in different terms and scales. In this study it is defined as in outdoor public spaces due to natural movement, involvement in different activities, and active or passive interactions. Today, the term of public life is a challenge since our societies are changing in different dimensions and it affects people’s presence as a response to urban environment. Study of public life and public spaces corresponds to a approach in planning and designing cities.

Urban design as an interdisciplinary profession is engaged with the of making good urban environment. Therefore this research explores how contemporary urban design studies and how it influences people’s behavior and by making potentials in public spaces. This study examines public life in public spaces through analysis of two perspectives, first contemporary urban design intentions for making places as a behavioral setting for public life, and second people’s responses to the urban environment. The aim is to find out whether design expectations are realized by users or not.

Method: Each urban environment has specific context to contribute to its users, influence their behavior and causes different and responses. So in order to acknowledge urban design intentions in framing public life, the research strategy is to focus on different cases, which have been newly designed and implemented. It should fulfill understanding of this process and the two perspectives, both in design and practice. To find out urban design intentions it suggests reviewing the proposals and design objectives besides the study of condition of design process. Likewise interviewing designers reveals how they define a good urban environment for public life. Simultaneously the project aims to evaluate the from its users’ perspective. Qualitative methods such as and conceptual mapping are proposed for data collection to investigate people’s action and perceptions as their response to the place.

Results: The results of methods provide a broad understanding about the process of creating places for high quality public life, and . In this progression, it points out the criteria used for a good urban environment in contemporary urban design through both designers’ and people’s perspective. Through analysis of the main socio-physical characteristics of urban environment that have a strong influence on people’s presence in public, it identify the role of contemporary urban design and highlights if there is a between people’s responses to design intentions in framing public life.

Discussion: The lack of public life in public spaces refers to the need of further study about interrelation between people and urban environment. The research argues the urban design progression that requires a deeper consideration of intentions related to places for human values and needs. It suggest to rethink about people’s perception and behavior which can be influenced by socio-physical environment, and relate these terms in design process. It discuss that to decrease the risk of creating places that are not being used as it is expected, providing a flexible framework to adapt people's need and behavior in design process is necessary. The research at the end aims to develop tools for urban design in order to create a link between life and physical space in cities.
