Abstract
The entrance space of a city acts as an urban space; a joint linking of natural space outside to artificial space inside. The illogical and unscheduled development of cities, as well as the lack of concern for suitable space development paradigms, has brought about weaknesses in the form and content of the entrance spaces of cities in Iran. This has caused numerous and various problems and disorders, which necessitate taking special, ground-breaking measures.These ravages have been so epidemic that these fields cannot even meet the minimum requirements to becalled as an urban area. The precipitous expanding of these ravages in these fields, which, in the future, will be the inner components of the city, represents the importance of the subject.Since the entrance space in cities and urban areas is considered one of the first spaces in the city to deal with the problem, given the input patterns in the spatial relationship between these subjects considered in urban areas are most basic challenges to be dealt with.To achieve the appropriate solutions in planning and organizing the entrance boulevards of the cities, at first we should consider the nature of entrances and know them then regard the characteristics of them.By evaluating of the changes of Entrance Boulevard of cities up to now, we can catch the social, cultural, political, economic and technological evolutions.Over time, the patterns of biological communities in settlements of the land are affected. Spaces, and the entrance gate into the old town, fort defined coordinates, entry to corridors with scattered, ugly, worn out and worthless residential buildings, and abandoned spaces, show disturbing reports of the uncontrolled growth and development of modern cities. A citys growth and beginnings or, in other words, definitions of the limits for a city, are irrelevant and meaningless.The present article tries to designate and reform a long forgotten urban sector in a new form, taking into account current needs and the functional organization of the entrances to cities in an appropriate way, to satisfy the needs emerging upon entering the cities. In this research, we have first identified and introduced the entrance as one of the urban spaces, as well as one of the important functions of entrance gates, causing consequential problems. Then, we have identified the factors affecting the design of city entrances. Considering the entrance to a contemporary city and the expectations at the main points of entry, and the ravages of the functions it has to grapple with, proper attention is paid to the obtained results. Considering functional regulations and criteria, as well as the entrance space of Zanjan (Tehran- Zanjan Express way), we have graphically designed these factors.
