The state of practice related to transportation performance measurements is developing rapidly in the European Community and all over the world. There is an abundance of material on the subject that describes the theory, offers recommendations for performance measurement programs, and documents experiences of agencies building and implementing their own programs. Interest is growing in enhancing management processes by including performance measurements as a core component. The Attica Tollway Operation Authority has developed a program of measuring and monitoring performance indicators, through an integrated Management Information System, in order to continuously improve safety, mobility, asset management and user satisfaction. The analysis of performance using key indicators provides motorway operators with a basis for redefining their activities. However, the real challenge is to effectuate improvements with the objective to widen the views of all parties involved in the road transportation system in order to reflect the vision of an integrated and sustainable transport system. INTRODUCTION Management Information Systems (MIS), is the discipline covering the application of people, technologies, and procedures — collectively called information systems— to solving business problems. MIS are distinct from regular information systems in that they are used to analyze other information systems applied in operational activities in the organization. Academically, the term is commonly used to refer to the group of information management methods tied to the automation or support of human decision making.
