Calibration and sensitivity analysis for LUTI models

This year, we have consolidated our previous works on calibration of LUTI models, in particular of the Tranus model [6]. The developed approaches are currently applied to instantiate a complete Tranus model for the Grenoble catchment area, in collaboration with AURG (Urban Planning Agency of the Grenoble area) and Brian Morton (U North Carolina).

We have also collaborated with the AIRSEA project-team towards applying novel sensitivity analysis tools to study the influence of the different parameter sets of a Tranus model [13]. The rationale is to then apply optimization methods to the most influential parameters. As a result, we were able to calibrate a real-life Tranus model such that results were of higher quality than with the baseline ad hoc approach, while reducing calibration time significantly.
