PORTIS is part of the European Horizon 2020 project. It brings together 5 big port cities: Antwerp, Aberdeen (Scotland), Constanta (Romania), Trieste (Italy) and Klaipeda (Lithuania). Through the realization of an integrated package of measures, the project supports sustainable mobility both in and between the port and the centre of these cities.

The City of Antwerp leads the project. Traject, together with the Port of Antwerp, the Province of Antwerp, de Lijn, de NMBS and BAM constitute the local consortium.

Traject is responsible for the evaluation of the measures realized in Antwerp.
