Un referentiel spatial pour la gestion de la voirie dans son environnement

The densification of urban basements into distribution networks leads to interventions involving different actors. These interventions generally impact the roadway, that is to say the entire road infrastructure, both structurally (vertical component) and superficially (horizontal component). In addition to the financial costs, each intervention can weaken the structure and disturb the various users. Our work aims at optimizing interventions by improving the coordinated management of data related to the road and its environment in a spatial reference frame. For that, we aim at a modeling adapted to the management of the infrastructure integrating the roadway and its constituent elements with the materials and their thicknesses. Our approach is organized in four axes: 1/ A description of the roadway's constituent elements, to propose a coherent vision to the actors. 2/ A study of the existing data for the management of the infrastructure, in order to identify the knowledge and the needs. 3/ A GIS modeling of the infrastructure to help communities to produce their data. 4/ An analysis of spatial interactions between roads and networks, to open discussions on construction choices. This article retraces all the work carried out for the four axes and proposes to open the debate on the design of a spatial reference system for roads adapted to their management.
