The multiexposure maps, representative of the year 2016, give an overview of the noise levels generated by all modes of transport on the national territory. It should be borne in mind that overall noise exposure is not synonymous with overall noise annoyance. Objective models such as the energy summation model simply give the immission level of exposure considering more than one noise source. The maps can be used to relate the different transport modes and show particularly noisy sections. For the design of technical solutions or the treatment of a complaint, source maps remain relevant in the search for solutions.-
