Abstract In this age of transition from decades of turmoil and instability in urban areas, urban centers validate their prestige and importance as a commercial, cultural and recreational center. Urban centers as the housing and shelter for millions of people and visitors will facilitate and improve human interaction. Since the city is very complex, existence and attendance of cycles of declining and wane, reform and reconstruction are obvious. At the best form, appearance of a city will be realized from its center & heart. Recently, in western countries, having vibrant and dynamic urban centers has caught the attention of many scholars. Actually creating an environment where social interaction is high and gives people a sense of vitality. On the other hand, to include such dynamism in context of an urban center, it needs adequate respondents. Therefore, in this paper, at firs the criteria for responsive environments, characters of a vibrant city center and the main & common features between them is introduced, using the analytic hierarchy process (AHP), criteria are weighted and prioritized. The results show that, sustaining the above criteria and codifying proposed policies and strategies, helps to recreate the historic core of Qazvin city. Keywords Vibrant city center, Responsive environments, Socialization, AHP, Qazvin 1. Introduction In Since the beginning of modern civilization, character of cities was distinguished by difference between private and public areas. The all times, it can be said that Greece rings were the best-known public spaces, public squares where the town meetings, public gatherings and places for ceremonies & feasts were considered, indeed, playing role as an integrated platform for social life in the city. In the middle ages, public spaces were still a main set to reveal public life. A few centuries later, during the industrial revolution, urban regions growth developed implementation of urban planning in practice, as cities grew by developing social networks [1]. Urban space is not just a physical concept, but also contains citizen interactions and civic engagements. It means that public spaces bring an imagination for city fabric where is a place of establishing urban activities or an incidence of social interactions [2]. In the new centuries, sustainable development, vitality, and competitiveness, are some of the terms that direct planning and urban development. As a result, city centers are faced with many challenges simultaneously. Urban growth, demographic changes, and efforts to improve the quality of life, all of these areas are contiguous. In fact, high population density and citizens living conditions determines success or failure of city. So studying the quality of urban life is one of the most effective ways to measure the urban competitiveness. Also, people fleeing from rural areas to growing urban centers for improving appropriate living conditions is needed for maintaining this development on the right track [1]. Successive public places are characterized by people's attendance, in this way characters of such spaces are corroborated inly. Basically the common spaces are to be used when necessary. People should take advantage of these environments while they can choose other spaces for use. Such spaces should be full of crowd and dynamic. The solution is that people gather what they are interested, around and inside themselves [3]. A dynamic environment can be supposed as a place where human presence is clearly seen and public space as a context of social interactions, have enough attraction for the selection of the people. Such space has standard criteria for permeability, sense of place, flexibility, visual proportions, organizing structure and etc. that during this research, using the opinions of planning and designing experts and applying analytical process model offers appropriate solutions for recreating of these features at environment (the historic core of Qazvin city).
