The TRB SimSub newsletter reports on the award-winning paper, co-authored by members of the TSS team and their associates, which discusses a metamodel-based technique for model sensitivity analysis and applies it to the Aimsun mesoscopic model.
The authors argue that the application of sensitivity analysis is crucial for the true comprehension and correct use of the traffic simulation model while also acknowledging that the main obstacle to an extensive use of the most sophisticated techniques is the high number of model runs that is generally required.
