The use of METACOR tool for integrated urban and interurban traffic control. Evaluation in corridor peripherique, Paris

Abstract

The paper presents the macroscopic corridor model METACOR, as well as its calibration and validation. METACOR, which was developed through the extension and the integration of two macroscopic traffic flow models, has been applied to the corridor peripherique test site to be used for model validation. The model results (regarding the output trajectories of the 3 traffic variables namely volumes, occupancy rates and speed), indicate that METACOR follows the time evolution condition in the considered network. This implies that METACOR is able to cope with different traffic conditions (fluid, dense and congested) at an acceptable level of accuracy. METACOR is a generally applicable macroscopic simulation tool for corridor traffic. Compared to other available tools, its main advantage is its moderate computational effort. This advantage is the result of a systematic macroscopic approach with destination-specific subflows that avoids iterations for dynamic traffic assignment.<>
