Denetimsiz Kavşaklarda Yanyol Katılım Kapasitesinin Modellenmesi

Abstract

Denetimsiz kavşaklar, şehiriçi trafik akımının yönetilmesinde etkin olarak kullanılan kavşak tipleridir. Denetimsiz bir kavşakta yanyol katılım kapasitesinin belirlenmesinde kullanılan hesap yöntemleri çoğunlukla analitik yöntemlere dayanmaktadır. Çalışma kapsamında yanyol katılım kapasitesinin hesaplanması amacı ile bir benzetim program yazılmış ve farklı koşullardaki yanyol katılımları için ampirik kapasite bağıntıları elde edilmiştir. Elde edilen bağıntılar literatürde yaygın olarak kullanılmakta olan bağıntılar ile karşılaştırılmış ve kullanılabilir oldukları belirlenmiştir.

Modelling Minor Approach Capacity of Unsignalized Intersections

Abstract

Unsignalized intersections are effectively used in urban traffic management. Capacity calculation methods for unsignalized intersections’ minor approach are usually based on analytical calculation methods. In this study, empirical capacity calculation equations are obtained by using a micro simulation program for different types of unsignalized intersections’ minor approaches. Obtained empirical equations are compared with the models which are commonly used in literature and the applicability of the equations is determined.
