The ITS Architecture for Malaysia provides a unified framework for integration to guide the coordinated deployment of ITS programs within the public and private sectors. It is a framework of interconnected subsystems that together provide ITS User Services through allocated functionality and defined interfaces. It offers a starting point from which stakeholders can work together to achieve compatibility among ITS elements to ensure unified ITS deployments for the country.

Based on the findings of the ITS Master Plan Study for Malaysia , a total of nine ITS sectors were identified together with thirty-six user-services. After refinement of the requirements for the user-services, the logical architecture can be derived from these services. Info rmation provided under the logical architecture includes data flows, data stores, process specifications, and terminators.

The development of the logical architecture would serve as support to the physical architecture where architecture flow indicates one or more data flows. The various processes identified in the logical architecture will be assigned to each subsystem in the physical architecture. In addition, a customized diagram showing the relevant subsystems and communication channels can be generated to illustrate system overview.

With the physical architecture defined and established, definition of deployment packages and selection of ITS standards will follow. These two activities can proceed simultaneously. Deployment packages allow the ITS system architecture developer to acquire the proper package from the market place while ITS standards ensures inter-operability of future systems.
