IMMISlaerm - Input Data

Input data 
When calculating evaluation levels the method for "long and straight" lanes is applied. The following measured variables are also included into the calculation of the emission level :
  • average daily traffic volume and truck parts or appropriately hourly traffic volume and truck parts for day/night 
  • Number of trams at day and night 
  • average length of tram and part of disk-braked trams 
  • Correction factor of different maximum speeds 
  • Correction factor of different road surface or types of tracks 
  • Addition for gradient 
  • Correction factor for the influence of single reflection

The following measured variables are considered when calculating the assessment level (noise pollution) : 

  • Addition by traffic light regulated crossings and junctions
  • distance and atmospheric absorption 
  • soil and meteorology absorption 
  • multiple reflection of street canyons
