Die nicht signalgesteuerte Nebenstraßenzufahrt als verallgemeinertes M/G/1-Warteschlangensystem

This paper deals with the queuing of side-street vehicles at high-priority traffic streams of unsignalized intersections. Among other results there are obtained the solutions for the mean delay of a low-priority vehicle and the probability of the waiting system being empty. In doing so, the system under study is reduced to a M/G/1 queuing system, where the service times of those vehicles that have to queue are different from the service times of those cars that arrive to find the system empty. The exact solutions are compared with commonly used approximate solutions and evaluated numerically. Thereby important information on the quality of those approximate solutions is obtained.
