From theory to practice: global sensitivity analysis of the Aimsun mesoscopic model
In this award-winning paper – originally published in the 2013 series of the Transportation Research Record: Journal of the Transportation Research Board – Biagio Ciuffo, Jordi Casas, Marcello Montanino, Josep Perarnau and Vincenzo Punzo discuss a metamodel-based technique for model sensitivity analysis and how it is applied to the Aimsun mesoscopic model.
The paper argues that sensitivty analysis is crucial for the best use of traffic simulation models while also acknowledging that the main obstacle to an extensive use of the most sophisticated techniques is the high number of model runs they usually require.
