The Role of the Uncertainty in ATISApplications

摘要

In recent years the interest toward ATIS (Advanced Traveller Informa-tion Systems) is constantly increasing, probably because of the intent of solving over-congestion with minimal expenditure. Great efforts have been devoted to both techno-logical and modeling aspects; however, a unified theory does not yet exist, as well as ageneral agreement on the objectives that can be achieved. It is not widely recognisedwhat can be expected from ATIS, how the information should be designed and howto assess/forecast the network level effects. Here the authors will present a theoreticalframework and some practical analyses, aimed to deal with the additional uncertaintiessometimes introduced in the route choice problem by the presence of ATIS.
