The main purpose of this research is to build an indices set, which can be embodied within a Decision Support System for road network infrastructure evaluation. Developing the urban transportation networks, it is obvious that the thorough study of the regional transportation networks is essential. What we plan for the urban areas infrastructure should be interrelated with the regional areas infrastructure in order to work in tandem. This indices set (DEcision Support Indices Set – DE.S.I.S.) is based on a certain database, and will adjust according to the data contained within this database. Should someone want to apply the DE.S.I.S. on a different database, the only thing he has to do is to re-calculate the set. The DE.S.I.S. will quantify, classify and compare the spatial \“demand” for road networks and the spatial \“offer” of the road network, considering mainly the population distribution within the administrative units (in this particular case, the regions). From that comparison, an evaluation of the road network will take place. GIS tools are remarkably useful for this purpose. The study area for the DE.S.I.S application is defined as the continental part of Greece. Concerning all the road network categories that exist, only the high-level ones are examined.

In Greece, although transportation infrastructure gets more synchronized every day, the low level of road network service is still present in certain regions of the country. Although, the urban transportation systems are thoroughly
