AsTra model


The ASTRA model has been developed since 1997 by IWW Karlsruhe and TRT Trasporti e Territorio first under the coordination of Prof. Werner Rothengatter and later of Dr. Wolfgang Schade. Since 2005, the model has been improved and maintained in the course of various projects by Fraunhofer ISI and TRT. Starting from 2015, M-Five is part of the team for the development of the model.
