Cycling is currently booming, as it is seen as an ecological, economical and efficient alternative to the car in urban areas. We are interested in how it is represented in mobility network databases (MNDBs). These are not of good quality because they are oriented towards other main uses (car, pedestrian) and the infrastructures are represented at the scale of the road section. Our study postulates that the representation of BDRMs at this scale only allows the main use of the latter to be represented, with little importance being given to secondary uses (e.g. cycling). Following this observation, we propose a definition of the cycle network as well as a new BDRM model, at the lane scale, adapted to cycling and allowing the representation of all road uses. We then instantiate this BDRM with the BDTOPO® and OSM. These two instantiations highlight quality problems in these two sources in order to obtain complete and fresh data. We address this question of freshness through the prism of network evolution analysis, particularly in OSM. To do this, we propose two complementary methods : one based on road sections, which is exhaustive over a large study area, and one based on non-exhaustive routes over small areas of interest that are representative of our study area. We are also seeking to make our work easily adaptable to any road user. The study area for all this research work is the Centre-Val de Loire region.
