Decentralized Data Allocation for Automatic Toll Collection Systems for Transportation Services


Mikio TANAKA
For the purpose of an automatic toll collection systems for transportation services, a decentralized data allocation method in distributed communication systems is discussed. A model to formulate the movement of users (passengers or vehicles) along a transportation network is proposed. Then the merits of user-ID based toll collection system is introduced. For the purpose of this user-ID based toll collection system, the allocation of replicated data over a transportation network is required in order to reduce processing time at exit nodes. Some methods to implement this system and methods to evaluate their costs are studied.
