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.

Keywords

Unsignalized intersection capacity, proportion of free vehicle, simulation
