In order to integrate transportation systems such as road traffic, rail signalling, bus management, air traffic control and shipping lane systems, it is important to establish a holistic concept design and technology inventory before beginning. At the heart of the integration process is the 3-Layer Object Model (3LOM). It consists of four primary components in three layers: 1) local units at the lowest layer; 2) a distributed database management system in the middle layer; and 3) a knowledge management and central control system at the highest layer. In this paper the authors continue the design of a future integrated transport management and will do so by concentrating on the middle layer; the conduit of 3LOM. It is responsible for the data acquisition management for the front-end devices in the bottom layer, the data management function, and reports refined information to the knowledge management system in the top layer. Specifically, the authors will propose an algorithm that allows the development of the middle layer of the 3LOM, and how it needs to function in order to succeed.
