The Directorate-General of the Roads French already had tools to know theconsistency and the state of the roadways and the structures of the National Road network but nothing concerning the road dependences and equipments. Therefore, Setra in collaboration with the Scientific and Technical Network has developed a methodology for the inventory and the statement of visual state of equipment and dependences of the road: the IQDE method (Image Quality of the Dependences and Equipment). The IQDE method defines a method of inventory and indicators of visual state in statistical matter of evaluation of a whole of work. The IQDE method is based on a visual examination (Quality Image). This makes it possible to state the majority of the dependences and equipment located on the roadway and the immediate surroundings of the road without disruption of traffic.
