تبیین عوامل طراحانه موثر بر شکل‌گیری بستر زندگی شبانه در فضاهای شهری (نمونه مورد مطالعه: خیابان کاشانی یزد)

شهرها در جهان معاصر در حال دگرگونی اند که از مهمترین ابزارهای این تحول بهره گیری از مولفه زمان و امتزاج آن با فرهنگ، هنر و فناوری در بازتولید فضاهای شهری است. امری که موجد پیدایش مفهوم زندگی شبانه و فضاهای شبانه شهری است. با توجه به اهمیت زمان در زندگی معاصر و تغییر ساختارهای زمانی به دلیل تغییر سبک زندگی، استفاده مطلوب تر از زمان در زندگی شهری در این فضاها می تواند تحقق یابد و سرزندگی حاصل از رخداد فعالیت های روزانه در ساعات شبانه امتداد یابد. در شهر یزد فضاهای شبانه ترغیب کننده حضور بیشتر شهروندان در فضا به ویژه در فصول گرم خواهند بود و با توزیع زمانی تراکم جمعیت و نگهداشت آنها در فضا در بازه زمانی طولانی تر نشاط و سرزندگی شهر که در حال حاضر یکی از مهمترین دغدغه های مدیریت شهری است را ارتقا می بخشد. با علم به این موضوع که بستر فضای شبانه ملاحظات طراحانه خاص خود را می طلبد، هدف پژوهش تبیین عوامل و معیارهای موثر بر طراحی فضاهای شبانه است. بر این اساس، پس از استخراج معیارهای موثر از میان متون نظری و تجارب مرتبط، این معیارها با بهره گیری از ترکیب روش کمی و کیفی، اولویت بندی و در خیابان کاشانی یزد ارزیابی شدند. در روش کمی به منظور اولویت بندی معیارها از ابزار پرسشنامه و آزمون های کلموگروف_اسمیرنوف و فریدمن استفاده شده و در روش کیفی این معیارها با استفاده از تکنیک های ارزیابی محیط (مشاهده، مصاحبه های باز، برداشت میدانی) در خیابان کاشانی یزد تحلیل شدند. براساس نتایج پژوهش ملاحظات طراحانه فضاهای شهری شبانه به دو دسته عوامل زمینه ساز در ارتباط با جذب جمعیت و عوامل پشتیبان در ارتباط با چگونگی نگهداشت جمعیت در فضای شهری، دسته بندی می شوند. عوامل زمینه ساز پتانسیل فضا برای ایجاد فضای شبانه هستند که با امتزاج با عوامل پشتیبان تقویت می شوند و نهایتاً با ارتقای کیفیت تجربه محیط موجب عملکرد صحیح فضای شبانه می شوند.

Explaining the Design Factors Affecting the creation of Nightlife in Urban Space (Case study: Kashani St., Yazd)

Highlights The most important criteria in nightlife spaces is Being and  safety has the least impact on creating an urban night space. Factors that affect night urban spaces design can be classified in two categories: Creator factors and Supporter factors. Creator factors are related to attraction and producing the night space and the Supporter factors are related to its population maintenance and how space is used and Determines the type and quality of space experience.   Introduction Cities are changing in the contemporary world, and the most important tools for this transformation involve the time component and it synthesis with culture, art, and technology to reproduce urban spaces. The result is the concept of nightlife and urban night spaces. Due to the importance of time in contemporary life and changing time structures resulting from lifestyle transformation, better utilization of time in urban life can be achieved in these spaces, and the vitality of daily activities can extend into the night hours. In the city of Yazd, Iran, night spaces encourage greater presence in space, especially in hot seasons, and enhance the city vitality, which is currently one of the most important urban management concerns, temporally distributing population density and keeping them in space for longer periods of time. Given that night urban spaces require their own design considerations, this study was aimed at explaining the factors and criteria that affect urban night space design. Theoretical Framework Two dimensions were identified for night spaces through a review of the literature on the definition of nightlife and 24hour cities and their analysis from the aspect of night urban space design. These included sociability arising from the physical space and perception of the function of space. Then, criteria and indicators were defined for the above dimensions. Methodology After the effective criteria were extracted from the literature and experience, they were prioritized using a combination of quantitative and qualitative methods and evaluated with respect to Kashani Street in Yazd. The most important advantage of this hybrid method, focused more on the qualitative aspect, involved the assessment and analysis of quantitative data in urban spaces and confirmation of the accuracy of the results through interpretation and enrichment. In order to prioritize the criteria in the quantitative method, the questionnaire tool and the KolmogorovSmirnov and Friedman tests were used (The reliability of the questionnaire was 0.812). In the qualitative method, these criteria were analyzed using environmental assessment techniques (field study and observation at different times in the period from 7 PM to 12 AM and open interviews) on Kashani Street. Results and Discussion The prioritization of the criteria indicated that flexibility had no effect on urban nightlife. Moreover, attendance exhibited the greatest and safety had the least impacts on the development of urban night spaces. The criteria were prioritized as attendance, security, inclusiveness, attractiveness, legibility, continuity, enclosure, spatial enticement, eventfulness, visual accessibility, and safety. A qualitative evaluation of these criteria in regard to Kashani Street demonstrated that the most important criteria, including attendance and security, provided the greatest potentials of this street for turning into an urban night space due to the density of activities and appropriate population. In contrast, criteria such as attractiveness, continuity, spatial enticement, and eventfulnessrequired plenty of design and planning to create urban night spaces. Conclusion Based on the results, the design considerations of night urban spaces were classified into two categories: creator factors and supporter factors. The former concerns attraction and construction of night spaces, while the latter pertains to their population maintenance and how space is used to specify the type and quality of space experience. The creator factors included attendance, security, inclusiveness, and attractiveness. The supporter factors included legibility, continuity, enclosure, spatial enticement, eventfulness, visual accessibility, and safety. The creator factors indicated the potentials of spaces for creation of the night space, reinforced through synthesis with the supporter factors and bringing about the correct performance of night spaces through improvement of the quality of the space experience. This proposed twofold framework could serve to complement the other aspects of night urban spaces (economic, cultural, governance, tourism, etc.) and to function as a guide to design of such spaces. In Yazd, night spaces provide contemporary responses to the new lifestyle to meet the needs of different groups, especially the youth, who can lead cultural challenges to creative use of their abilities. Combination of nocturnal spaces with urban tourism can create a new experience of being there at historical places and presenting the contemporary assets of the city along with its historical assets. It provides a booming service economy for sustainable urban development.
