Layer-based data structure for integrated transport system

The notion of integrated transportation systems (IntegTS) is an attempt to find a solution to the way in which one can coordinate disparate organisations through their information systems infrastructure. Underlying IntegTS is the intention to integrate various transport-oriented information systems into one overarching system to improve efficiency, flexibility and safety of transport related activities. The base design of the new system uses the Three Layer Object Model (3LOM) which consists of managing front-end components, database management and knowledge management. This paper proposes a design policy and physical data structure of the database system to be implemented in the IntegTS. There are currently some proposals for data models for transportation management; however, those data management systems focus on specific purposes/issues, such as an extending transportation planning models, or an on-road driving database. The most important requirement for the model is how to maintain the stability of the target transportation system and recommend the best alternatives in the case of emergencies. The paper describes the layered design of IntegTS that consists of a general map, a general transportation system, a schedule based transportation system, a non-schedule based transportation system, and a railway transportation system.
