Public transport faces a challenging period in which relevant operators invest in telematics systems in order to upgrade their internal operations and improve the services provided. Moreover; the public transport system has become quite dynamic during recent years, in the sense that the performance, effectiveness, and quality of its processes depend, to a large extent, on the factors affecting the vehicle's daily trans~ portation work. Under the Ph.D. program at the Aristotle University ofThessaJoniki, TeJematics Applications in Public Transport, the Jack of a complete management information model, that will effectively integrate traditionally static and dynamic public transport operations was identified. This article provides an overview of the management information model MIDAS-the result of a six-year research and development effort, aimed at fulfilling this gap. The article puts particular emphasis on the methodology applied and the techniques employed for development of the model. MIDAS contains three types of interrelated models: data model, functional model, and dynamic model. These models are the basis for the design and develop~ ment of information systems for the planning and management of public transport operations.
