Abstract

Amaç: Bu çalışmada; mekan dizimi analizi, uzun görüş hattı analizi ve tampon analizi kullanılarak Ordu ili Akyazı Mahallesi’nde farklı gözlem noktalarının görsel erişilebilirlik ve mekansal bileşenler ile ilişkisini incelemek amaçlanmıştır.
Materyal ve Yöntem: Akyazı Mahallesi’nde mekan dizimi analizleri gerçekleştirilmiştir. Bu analize göre dizimsel analizin yüksek değer alan yollarının kesişim noktalarında üç farklı gözlem noktası (G1, G2 ve G3) belirlenmiştir. Bu noktalar için uzun görüş hattı analizleri ile tampon analizleri yapılmıştır. Elde edilen veriler karşılaştırmalı olarak değerlendirilmiştir.
Araştırma Bulguları: Analiz sonuçları, G1’in en yüksek görsel erişilebilirlik seviyesine sahip olduğunu, buna karşın G2 ve G3’ün görüş kapasitelerinin mekansal kısıtlılıklar nedeniyle daha sınırlı kaldığını göstermektedir.
Görsel erişilebilirlik düzeyindeki farklılıkların temel nedenleri, mekansal yapı, bağlantılılık değerleri, yapı yoğunluğu, açık alan varlığı, dar sokaklar, bina yükseklikleri ve çevresel engeller gibi mekansal faktörlerdir. Dizimsel analizlerin bağlantılılık ve bütünleşme değerleri üzerinden erişilebilirlik düzeylerini belirlemiş, uzun görüş hattı analizleriyle birlikte değerlendirildiğinde, erişilebilirlik, görsel algı ve yaya hareketliliği arasındaki mekansal ilişkilerin daha belirgin hale geldiği görülmüştür. Tampon analizi, gözlem noktalarının çevresinde oluşturulan tampon bölgeler aracılığıyla yürünebilirlik ve erişilebilirlik düzeylerinin mekansal organizasyonla ilişkisini ortaya koymuştur.
Sonuç: Sonuçlar, mekan dizimi analizi, uzun görüş hattı analizi ve tampon analizinin, kentsel tasarım ve mekansal planlamada önemli değerlendirme araçları olduğunu göstermektedir. Görsel erişilebilirliğin artırılması için yapılaşma yoğunluğu, açık alan planlaması ve sokak tasarımı gibi unsurlarla bütüncül bir şekilde ele alınması gerektiği değerlendirilmektedir. Bu bağlamda çalışma, Akyazı Mahallesi'nde kent içi erişilebilirlik, yürünebilirlik ve mekansal algının daha verimli tasarlanabilmesi için mekan dizimi analizi, uzun görüş hattı analizi ve tampon analizinin birlikte kullanılmasının etkin bir yöntem olabileceğini önermektedir.

Quantitative Analysis of Street Network Features Using Space Syntax and GIS-Based Approaches: Ordu (Akyazı Neighborhood), Türkiye

Abstract

Objective: This study aims to examine the relationship between visual accessibility and spatial components of different observation points in Akyazı Neighborhood of Ordu province by using space syntax, long line of sight and buffer analyses.
Materials and Methods: Space syntax was conducted in Akyazı Neighborhood. According to this analysis, three different observation points (G1, G2 and G3) were determined at the intersection points of the high value paths of the sequential analysis. Long line of sight and buffer analyses were performed for these points. The data obtained were evaluated comparatively.
Results: The results of the analysis show that G1 has the highest level of visual accessibility, whereas the viewing capacities of G2 and G3 are more limited due to spatial constraints. The main reasons for the differences in the level of visual accessibility are spatial factors such as spatial structure, connectivity values, building density, presence of open space, narrow streets, building heights and environmental barriers. Sequential analyses determined accessibility levels through connectivity and integration values, and when evaluated together with long line of sight analyses, the spatial relationships between accessibility, visual perception and pedestrian mobility became more evident. Buffer analysis revealed the relationship between walkability and accessibility levels and spatial organization through buffer zones created around the observation points.
Conclusion: The results show that space syntax, long line of sight and buffer analyses are important evaluation tools in urban design and spatial planning. In order to increase visual accessibility, it is evaluated that elements such as building density, open space planning and street design should be handled in a holistic manner. In this context, the study suggests that the combination of space syntax, long line of sight analysis and buffer analysis can be an effective method to design urban accessibility, walkability and spatial perception more efficiently in Akyazı Neighborhood.
