Test cases for control of Nord2000
5 Test Cases for the Yearly Average
Concerning the terrain (flat grass-covered ground) and the traffic, the test cases used for calculation of the yearly average Lden are identical to Test Case 4 in the "Straight Road" group. Four cases of the
position of the road and position of the receiver have been included:
- Case 1: The road placed North-South with the receiver East of the road
- Case 2: The road placed North-South with the receiver West of the road
- Case 3: The road placed East-West with the receiver South of the road
- Case 4: The road placed East-West with the receiver North of the road
The method for calculating the yearly average of Lden is described in [5] which also contains the meteorological statistics to be used in the calculcations. The meteorological statistics can be found in the
Excel spreadsheet containing the calculation results.
Lden is calculated for 10,000 category-1 vehicles each day throughout the year, and the vehicles are distributed on day, evening, and night time by 7889, 791, and 1320, respectively. The vehicles are
driving in the middle of the lane nearest to the receiver, and there is no traffic in the far lane.
The results of the 4 cases are given in the Excel spreadsheet "TestYearlyAverage.xls" with one worksheet for each case. An example of a sheet is shown in Appendix D (Case 1).
