Abstract
A new procedure for delay estimation at congested two-way stop controlled intersections was developed. Total delay was divided into two parts; service delay and queue delay. A linear empirical model was developed to estimate the average service delay as a function of conflicting traffic volumes. A set of empirical models was developed to estimate the average queue delay as a function of the subject approach traffic intensity. It was found that the queue delay increases exponentially as traffic intensity increases. The field data was used for comparing the proposed total delay model with the 1994 HCM model. It was found that the proposed model is significantly closer to the field data. It was also noticed that the 1994 HCM model underestimates the total delay. The proposed delay model is very practical and uses only two input variables; arrival rate and conflicting traffic volume.
