In terms of their structure and operation, most transportation systems, and in particular urban passenger transport, are spatial stochastic queueing networks (SSQN). In transportation systems, the customers are the flows of goods or passengers, and the accumulator systems (ACs) are the freight concentration depots or stations in an urban transportation network. The simplest SSQN is an elementary SSQN (ESSQN) having the following properties: it consists of finitely many ASs in a series; the multichannel queueing system is empty when it reaches the first AS from the external source; the service of all the customers transported by the MS is completed in the last AS. The ESSQN is the basic component element in the topology of transportation systems. Using these elements, one can assemble SSQNs of sufficiently large dimension with a variety of operating modes. This article investigates ESSQNs in the stationary operating mode.
