High Availability Telematic Management System

An efficient use of ITS resources depends on the information and communications architecture that enables the optimal use of technology, information and, increasingly, services, available across the variety of ITS applications and systems. This is especially true for the quality of service requirements, namely availability.
The current article focuses on architectural concerns in the development and
deployment of the VMS operation component of Traffic Atlas. This component is cross-cutting in regards to the multi-layer service-oriented architecture of Traffic Atlas; in order to simplify our approach, a VMS-centric approach is taken at each layer.
