MULTITUDE, COST Action TU903
MULTITUDE - Methods and tools for supporting the use calibration and validation of traffic simulation models.
The project examined issues such as data availability and quality, as well as the relationship between data accuracy and calibration, as well as developing and testing methodologies suitable for calibration and validation of deterministic as well as stochastic models. Major accomplishments were the definition of a general framework for the management of uncertainty in traffic simulation, the development and application of Global Sensitivity Analysis techniques to traffic simulation, the building of a new simulation platform to benchmark dynamic origin-destination (OD) estimation and prediction algorithms, and the development of a new methodology to reconstruct trajectory data from noisy measurements, applied to NGSIM I80-1 dataset.
