Abstract

The article presents the author’s own method of determination of capacity of movements from minor entries at an unsignalized intersection, when turning vehicles join the queue of vehicles on the main street, generated due to the influence of an adjacent signalized intersection. The proposed method of capacity calculation consists of four steps. First, the length of lane vacated by the vehicles leaving the signalized intersection was calculated. Second step consisted in determination of capacity of the right-turn movement joining the queue. In the following step, capacity of the left-turn movement joining the queue was calculated. The last step consisted in calculation of the time in which the intersection is blocked by vehicles moving ahead in the queue.

Keywords


capacity, unsignalized intersection, vehicle queue.
