The City of Trieste will create an urban access control system to monitor traffic flows of cars and heavy vehicles entering and leaving the city through specific entry points near the Old Port, and to control the usage of particular areas nearby such as pedestrian areas and limited traffic zones. The system will consist of cameras, detectors and other monitoring devices. Pedestrian areas and limited traffic zones in the old city centre will be monitored to preserve soft mobility and guarantee that mobility rules are respected. The monitoring of city access, on the other hand, will be aimed at collecting traffic data to be used in the city’s transport and urban planning, for new smart mobility solutions, and to enhance multimodal mobility systems. In particular, traffic data will be used in SUMP development and will feed the transport information platform in order to provide real-time information. The measure includes the implementation of a pilot project consisting of the monitoring of a localized area (pedestrian or limited traffic zone) in the old city centre and the installation of detectors in specific city access points.
