  "text": "Before and after crossings with traffic lights and roundabouts a correction shall be applied for the effect of acceleration and deceleration as described below.\nThe correction terms for rolling noise, ΔLWR,acc,m,k , and for propulsion noise, ΔLWP,acc,m,k , are linear functions of the distance x (in m) of the point source to the nearest intersection of the respective source line with another source line. They are attributed to all octave bands equally:\nΔL WR,acc,m,k = C R,m,k × Max 1 − x 100 ;0\n(2.2.17)\nΔL WP,acc,m,k = C P,m,k × Max 1 − x 100 ;0\n(2.2.18)\nThe coefficients CR,m,k and CP,m,k depend on the kind of junction k (k = 1 for a crossing with traffic lights; k = 2 for a roundabout) and are given for each vehicle category. The correction includes the effect of change in speed when approaching or moving away from a crossing or a roundabout.\nNote that at a distance |x| ≥ 100 m, ΔLWR,acc,m,k = ΔLWP,acc,m,k = 0.",
