Copula-based scenario generation for urban traffic models

作者:

Highlights:

• Statistically-sound what-if scenario generation for urban traffic models.

• Data-driven generation through copula models trained on available data.

• The method can be applied to any traffic model and arbitrary sets of input parameters.

• Joint dependence of generated inputs is preserved, beyond simple correlation analysis.

• Simulation results are provided for both a large-scale and a microscopic model.
