Abstract :
This paper investigates three methods for dynamic network loading that are considerably less detailed than microscopic modeling. Each of the three methods is based on a different approach to modeling traffic dynamics: link-based travel time functions, the cell-transmission model, and a link-based model derived from a simplified car-following relationship. A small test network was devised and the results from each model were compared to those obtained with a micro-simulator (INTEGRATION). Interpretation of the discrepancies observed in the results gives some indication of the relative importance of the different components of the three traffic models presented
