This paper addresses the theoretical aspects of a dynamical systems based on stable dynamie traffic assignment (DT A) strategy for traffic networks equipped with advanced information systems. A non-linear dynamical system formulation is proposed. The solution existence is analyzed. The concept of time-dependent link performance functions is used to capture the time dependency of dynamie traffic networks. The assumptions on the link performance functions and their implications for the stable DT A strategy are discussed. Insights on the model behavior and system properties are illustrated using a two-link network. The Lyapunov-based theoretical stability analysis is related to the conceptual stability definitions.

Artykuł przedstawia teoretyczne aspekty dynamicznych systemów opartych na stabilnej strategii dynamicznego przydziału ruchu dla sieci wyposażonych w zaawansowane systemy informatyczne. Przedstawiono nieliniowy opis sytemu dynamicznego i zbadano istnienie rozwiązania. Do określenia zależności czasowych dynamicznych sieci ruchu użyto funkcji zależnych od czasu wykonywania połączeń. Przedyskutowano założenia funkcji wykonywania połączeń i ich skutków dla stabilnej strategii dynamicznego przydziału ruchu. Zachowanie się modelu i własności systemu są ilustrowane siecią dwupołączeniową. Analizę stabilności przeprowadzono o metodę Lapunowa.
