The objective of the LIST Port app is to provide information to users, be they tourists or travelers, which allow a reduction of road congestion and noise pollution on the access and egress routes in the port areas of the cities of: Vado Ligure, Olbia, Bastia and Piombino. The app consists of 4 sites, each relating to a port city taken into consideration in the project: Vado Ligure, Olbia, Bastia and Piombino. It is organized into: a common part, which consists of the routing and routing package to and from the port terminal; and in a specific part of each of the four cities, which provides further information, starting from the digital services available and accessible locally. User routing strategies are defined on the basis of both congestion and noise pollution. The app also allows you to view the state of congestion in correspondence with the cameras installed in the LIST Port project and the messages reported by the PMVs. The additional services provided by the app include: departure and arrival times of the ships in the port in real time, redirection to the booking websites of the maritime services available in the ports, information on public transport and rail services, for users who they go to the port by public transport.
