Km of total revetu road network

To calculate the length of the paved road network, the kilometres of the different networks are added up. The following shall be considered: highways (AR) and rings with motorway status, regional roads (not including entrances/exits of AR and RN, car parks...), regional roads (including entrances/exits of motorways and national roads, car parks...), all provincial roads, carossable municipal roads, excluding, in principle, agricultural and trails and roadways included in the municipal network (yet provincial). Note: the length on 1 January of year x is assumed to be equal to that on 31 December of year x-1. The important thing is to know that this data is valid on the first January of each year.
