Defining a Structural Model for the Revitalization of the Lost Urban Spaces (City Entrances) in Contemporary Urban Design Case Study: Entrance of Sanandaj

Not long ago, city gates and entryways had high spatial value and were among the landmarks for marking city boundaries. Today with cities having been expanded and developed, such aspect of the entrance concept is lost and entryways are turned to passages for transportation. In fact, the rich spatial value of such entrances has decreased as they are solely spaces for passing through out or into the city. The dissonant expansion of entryways causes irregularities in thresholds of urban structure. This is due to imprudent intrusion into city landscape entailed by ill-considered planning activities. The main problem is the lack of comprehensive visual or mental definitions in the field. In other words, the challenge includes improper sequencing, zoning, and lack of lucid scenario and interfere procedure. Through defining a scenario, this study aims to set a spatial hierarchy for urban entryways. It then uses a comparative study to examine the scenario for an existing case study. This study provides a new definition for designing and planning for the fields concerned with city entryways. This implies methods by which authorities can interfere in the process of urban design.
