Abstract
This study focuses on the curb lane, where both left-turn and through traffic pass, which conflicts with pedestrians and bicycles. The model of discharging flow at curb lanes is derived theoreticaly, and it represents the interruption of left-turn viehicles caused by pedestrians and bicycles. Through cars do not utilize fully at curb lanes because left-turns conflicting with pedestrians and bicycles exist. The arrival flow of each lane at an approach is generally different. The new analysis method to allocate total arrival flow at an approach to each lane is proposed. The method assumes that all the queues of lanes at an approach, discharge at equal period during green interval, excluding exclusive right-turn and/or left-turn lanes. The lane flows allocated by this method are compared with the observed flows. As a result, it is proved that, the allocated lane flows correspond to the observed ones and the new method can exactly estimate the lane flows from the given arrival flow at an approach.
