Type A and C noise maps dedicated to road and rail traffic make it possible to assess the exposure to noise induced by road and rail traffic in a given territory. Noise levels are expressed in Lden (level day evening night) representing the hour-weighted daily average level (day noise [6h-18h], evening [18h-22h] and night [22h-6h]) and Ln (level night) describing the average night noise level for the night period [22h-6h]. Type B maps represent the sectors affected by noise in the sense of noise classification of land transport infrastructure (railway and road).
