Abstract
For the purpose of an automatic toll collection system for transportation services, a method of data re-allocation according to related entity in distributed communication systems is discussed. A simple model to formulate the movement of users (passengers or vehicles) along a transportaion 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 re-allocation of 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.
