摘要：To ensure the management and maintenance of road rights-of-way, it is useful to have a surface representation of this infrastructure. A method commonly implemented (developed by CEREMA ex-CERTU) the linear-based method consists of relying on road data organized in the form of a graph, therefore composed of lines (arcs) to which widths are assigned according to parameters, estimated a priori from the road characteristics. On the basis of cadastral data, we designed another approach, in our previous works, making it possible to produce surface area data for roads without relying on predefined parameters linked to the characteristics of the infrastructure. This article is a methodological contribution aimed at studying and comparing the results obtained by these two methods. For this, the two methods are implemented on 4 case studies: Paris, Bordeaux, Rouen and Cachan. The results are then compared to benchmark data. This work confirms the interest of the cadastral-based method by demonstrating that it allows the production of more precise surface data of road rights-of-way. They also make it possible to conclude on the complementarity of the two approaches, to produce surface data distinguishing the pavements from their dependencies.
