The city center of Turku is expanding towards the harbor, enhancing the symbiosis between the city and the port. Digitalisation enables efficient and sustainable interaction between the city and the port. The City of Turku strives to become a smarter city by prioritizing data efficiency, environmental sustainability, and social inclusion, while the Port of Turku aims to enhance smartness in terms of augmented efficiency, user-friendliness and security measures. The Smart Port City project explores the links between these goals. It lays out a vision of a Smart Port City where city, port, as well as inhabitants, and visitors are recognised as key stakeholders.
