TRAFFIC EQUILIBRIUM IN A DYNAMIC GRAVITY MODEL AND A DYNAMIC TRIP ASSIGNMENT MODEL

This paper is concerned with the analysis of traffic network equilibria in a dynamic gravity model and a dynamic logit-based trip assignment model. These two models have a similar mathematical form and so are put together for consideration. Both models were suggested by Dendrinos and Sonis (1990) as modifications of, respectively, the conventional static gravity model (Ortuzar and Willumsen, 1990) and the logit-based trip assignment model (Dial, 1971), but without giving any detailed analysis.
