Abstract

It is a problem of concern to quantify the effect of pedestrian traffic on capacity of signalized intersections. The behaviors of pedestrians and mechanism of pedestrian-vehicle conflict are analyzed in this paper. Pedestrian arrivals in groups are taken into account. Capacity of conflict zone is modeled based on platoon analysis method. The model is calibrated according to field data and lays a foundation for calculating capacity of signalized intersections influenced by pedestrian traffic. Vehicular capacity computed by the proposed model depends much on average conflict times and is generally lower than that by method of Highway Capacity Manual (HCM, 2000) . The downtrend of vehicular capacity becomes less and less sharp accompanied by the increase of conflicting pedestrian volume. The proposed model is developed on basis of mechanism of conflict zone, and is more universally applicable. The research provides a theoretical basis for signal timing and traffic management at intersections in mixed traffic condition.
