PROCESS FOR THE DETERMINATION OF THE CAPACITY AND SERVICE LEVEL OF A COMPLEX JUNCTION DIRECTED BY TRAFFIC SIGNS

Abstract

The process determines the number of the vehicles waiting in the minor direction, their average delay and the service level for a complex junction directed by traffic signs. The basic volume of the traffic to be transmitted from the subordinate direction can be read from the diagram (curve) originating in the survey results. This basic volume should be corrected by correction factors depending on the speed; on the number of the main road lanes; on the way of traffic control and on the hindrance. The number of the waiting vehicles as well as the average delay suffered by the vehicles moving in the minor direction. The process is also appropriate to define the lane number necessary on the waiting section in the minor direction and their arrangement. Also a computer progralll was prepared for the execution of the computing.
