Tasarım süreçlerinin artan karmaşıklığı, tasarımcı ile kullanıcı arasındaki mesafeyi arttırmakta ve bu da tasarımda kullanıcı deneyimini göz önünde bulundurmayı zorlaştırmaktadır. Kullanıcıların otonom karar verme varlıkları olarak temsil edildiği hesaplamalı modeller kullanıcı davranışlarının benzetim modelleri ile temsil edilmesinde yardımcı olmaktadır. Bu bağlamda, modellerin geliştirilmesi kentsel tasarımın erken aşamasında karar vermeyi desteklemektedir. Bu çalışmanın amacı, kullanıcının kentsel mekâna nasıl dahil olduğunu araştırmak ve kullanıcı hareketinin benzetimi için bir model geliştirebilmek ve kentsel alan bileşenleri ile kullanıcıların hareketi arasındaki ilişkiyi analiz etmektir. Bu makale beş aşamalı ardışık bir süreci takip etmektedir: Gözlem çalışmaları ve çevresel analiz ile veri toplama; Verilerin bulanık mantık kullanarak yorumlanması; Etmen tabanlı model geliştirme; Model uygulama; Değerlendirme ve doğrulama. Gözlem verilerinin yorumlanması, kentsel mekân bileşenlerinin etki değerlerini bulanık mantıkla hesaplama süreçleridir. Bu değer, daha sonra etmen tabanlı benzetim modelinde etki kuvveti olarak tanımlanır. Benzetim modeli sonuçları, gözlem çıktıları ile karşılaştırmalı olarak değerlendirilmektedir. Örnek vaka incelemesi olarak, bir kentsel meydan seçilmiştir (Konak Meydanı, İzmir, Türkiye). Sabah ve akşam zaman dilimleri için iki model tanımlanmış ve meydandaki kullanıcı hareketinin benzetimi için test edilmiştir. Daha sonra model sonuçları ve gözlem verileri Ortalama Mutlak Yüzde Hata (Mean Absolute Percentage Error - MAPE) ve Sekant Kosinüs Hesaplama yöntemleri ile karşılaştırılarak modelin verimliliği incelenmiştir.
