ESTIMATION METHOD OF LEFT TURN LANE CAPACITY UNDER THE INFLUENCE OF PEDESTRIANS AND CROSSWALK LAYOUT AT SIGNALIZED CROSSWALKS

The left turn lane capacity is highly influenced by the presence of pedestrians under shared signal phasing. Pedestrian crossing time can be pedestrian platoon maneuver influence traffic settings, crosswalk length and bidirectional interactions pedestrian, due to that turning vehicles movement may significantly affected. However, existing estimation methods lanes did not consider those factors. In addition, layout properly in researches. This study aims propose a method estimate capacity, considering characteristics variations. Waiting presence-time estimated applying probability model. discharge flow rate different demand condition are investigated modeled. equation proposed characterizing observed pedestrians. It was found represent realistic on at signalized crosswalks.
