5 Test Cases for the Yearly Average

Corrected test cases for control of Nord2000-road

Concerning the terrain (flat grass-covered ground) and the traffic, the test cases used for calculation of the yearly average L_den 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 L_den is described in [5]. The meteorological statistics to be used in the calculations can be found in the Excel spreadsheet file containing the calculation results (in the sheet “Met. statistics”).

L_den 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_20090216.xls” with one worksheet for each case. An example of a sheet is shown in Appendix D (Case 1).
