COREALIS proposes a strategic, innovative framework, supported by disruptive technologies, including IoT, data analytics, next generation traffic management, for modern ports to handle future capacity, traffic, efficiency and environmental challenges. Through COREALIS, the port will minimize its environmental footprint to the city, it will decrease disturbance to local population through a reduction in the congestion around the port. COREALIS proposes a bunch of solutions for the ports based on big data analytics: i) a predictive model for maintenance for the port of Piraeus ii) a cargo flow optimizer based on historical and current data for hinterland connection applying at the Port of Antwerp iii) an optimized Truck Appointment System based on an Estimated Time of Arrival through real time data.
