Traffic delay is one of the essential aspects taken into consideration in the evaluation of operational performance of intersections. Delays at stop-controlled intersections are estimated using mathematical models that estimate the delays experienced by the minor road vehicles. However, the applicability of the existing mathematical models is subjected to the traffic local conditions. This paper discusses a current research carried out to develop a new model for the estimation of traffic delays experienced by the minor approach vehicles at stop-controlled T-intersections. Data pertaining to the analysis of traffic delays was collected at two stop-controlled intersections using a video camera recording technique. A dimensionless method was applied in the analysis of the data and two mathematical models for the estimation of delay to the right- and also left-turning manoeuvre on the minor approach were proposed. In this case, the comparisons between actual delays and the values predicted using the dimensionless method showed that there was no significant difference between the values. As such, it was suggested that the mathematical dimensionless-based models developed in this study are directly applicable, with a reasonable accuracy, for the analysis of traffic delays at stop-controlled T–intersection.
