Macroscopic traffic simulation for on-line forecasting

摘要

Recently the Dutch road authority, Rijkswaterstaat, finished the pilot installation of a macroscopic flow model for on-line traffic forecasting. The projected use of this model is to assess different control strategies by including the model in a decision support system in traffic control centers. After an international survey, the model METANET (developed in EU research programs) was chosen for this purpose. The installation was performed on a small network that however contains possibilities for route choice and on wich various traffic control measures are available. The experimental character of th installation motivated the choice of pragmatic solutions of various modeling difficulties. This contribution describes the approach and results of the pilot installation.
