Over the past decades, mobility system has become one of the main concerns and urban designers and planners have paid more attention to highways rather than citizens and pedestrian areas. The present study aims at analyzing the relationship between the walkability and sustainability in urban planning. It also aims at explaining the possible advantage for both urban environment and people. For residences of city, it can be highly effective on economic and health of people and for talking about the urban part, it leads to a sustainable community for having secure, comfortable and useful environments. In addition, another focus of this paper is using mixed use methodology for not only analyzing quantitative but also qualitative indicators for walkability analysis.
