Summary:A new method of capacity analysis at unsignalized intersections has been developed in this study for Indonesia where the drivers’ behavior, traffic composition, level of roadside activities are different from those in developed countries. Typical cities in developing countries performed by the heterogeneous traffic mixed including fast–moving vehicles (motorized) and slow–moving vehicles (unmotorized). Traffic rules for examples like give-way or lane discipline are neglected in most cases. The study focused on ten three–leg unsignalized intersections in a suburban city in Indonesia. The new method was based on the interactions between conflict streams (six streams and six conflict points) having the average speed and flow of each stream. All possible conflict streams were considered simultaneously and the interactions were taken into account through empirical regression models. The results of capacity analysis from this proposed method correspond properly with the results from the current Indonesian Highway Capacity Manual (IHCM). © 2011 Published by Elsevier Ltd.
