Abstract
A New Method for Determining Saturation Flow Depending on Driver Behaviour Saturation flow is a basic parameter used in design of signalised intersections. Uncertainties in determining saturation flow causes some deficiencies in calculation of capacity and level of service. HCM suggests two methods for determining saturation flow; analytical and observational, which are very common all over the world. Analytical method uses factors effecting saturation flow as coefficents. On the other hand, effects of driver behaviour are not clearly included. In this study, initially a new analytical modelling based on driver behavior is presented; then the results are compared with field studies and HCM method. The results of the recommended method are encouraging

Abstract
Doygun akım, ışıklı kavşak tasarımında kullanılan temel parametrelerden birisidir. Doygun akımın doğru olarak tespit edilmemesi, kapasite ve hizmet seviyesinin doğru olarak belirlenememesine neden olmaktadır. Doygun akım hesabı için, HCM tarafından ortaya konulmuş, biri analitik, diğeri gözlemsel olan iki yöntem dünya çapında kabul görmektedir. Analitik yöntem, doygun akımı etkileyebilecek değişik faktörleri bir çarpan olarak kullanmaktadır. Bununla beraber, sürücü davranışlarının doygun akıma etkileri henüz tam olarak ortaya konulmamıştır. Bu çalışmada, öncelikle doygun akımı ifade edebilecek, sürücü davranışlarına bağlı yeni bir analitik yöntem ortaya konmuş, ardından bu yöntemin geçerliliği arazi gözlemleri ile denenmiş ve sonuçlar HCM yöntemlerinden elde edilen sonuçlar ile kıyaslanmıştır. Önerilen yöntemin kullanımı konusunda oldukça umut verici sonuçlar elde edilmiştir
