National Traffic Information Centres
Responsibilities and objectives
The acquisition, cataloguing and distribution of data and information – towards Public Entities, Enterprises, and citizens – concerning the road network events and driving conditions, is the main objective of a National Traffic Information Center (TIC). This objective often extends up to include maritime, air and rail transport events.
An event that causes discomfort or reduced mobility on the territory is a phenomenon of an indefinite duration. It is detected by several possible actors (citizens, local police, traffic police, rescue vehicles) and updated according to the dynamic development of the event.
TIC will receive data and overlying info, in different formats, until the end of the event.
It is evident that this picture becomes even more complicated in the presence of events that are close together in spatial and temporal terms, or still when the event has a progressive territorial impact. In the latter cases, the TIC need to understand to what event the information received from the different operators at the site of the event refers, or what is the correct time sequence of the events, which follow each other on the basis of information sent by different operators at different times.
