Miljøstyrelsen bad DELTA om at udarbejde et sæt af beregningsforudsætninger og dertil hørende beregningsresultater, som kan benyttes til test af computerprogrammer, der beregner vejtrafikstøj efter den nye nordiske beregningsmetode Nord2000.

Testeksemplerne er udvalgt i samråd med projektets følgegruppe, og de omfatter alle relevante parametre i beregningsmetoden. For hvert beregningspunkt er det angivet, inden for hvilke intervaller beregningsresultaterne skal befinde sig, for at den testede software kan siges at regne korrekt i henhold til Nord2000.

Målgruppen for rapporten er konsulenter og firmaer, som fremstiller eller markedsfører beregningsprogrammer.

Foreword

The Danish Environmental Protection Agency has asked DELTA to develop test examples, which are a set of presumptions together with corresponding computation results, suitable for verifying that computer programmes indeed do perform in conformity with the new Nordic prediction method for road traffic noise, Nord2000.

The test examples have been selected after consultations with a project steering committee, and the examples comprise all relevant parameters in the prediction method. Intervals have been specified that computation results shall fall within in order for the software to be declared as in conformity with Nord2000.

The target group for the present report is consultants and developers or distributors of software for road traffic noise prediction.

Sammenfatning og konklusioner

Rapporten indeholder testeksempler med forudsætninger for og resultater af beregninger udført ved hjælp af den nye nordiske beregningsmetode for vejtrafikstøj, Nord2000. Testeksemplerne skal benyttes ved kontrol af, at computerprogrammer beregner i overensstemmelse med den nye nordiske beregningsmetode. Der er fire grupper:

Resultaterne er samlet i et Excel regneark for hver gruppe.

Summary and conclusions

The present report contains a number of test cases calculated by the new Nordic road traffic noise calculation method Nord2000. The purpose of the test cases is to provide a basis for testing software developed according to the new Nordic model. The test cases are divided into four groups:

The group "Straight Road" contains 62 cases for a straight road with only one lane carrying traffic and includes results of L_Aeq,24h, L_AE and L_Amax.
The group "Curved Road" contains 8 calculation points distributed along a road with two lanes and a turn, looking more like a "real" case. The group includes results of L_Aeq,24h and L_Amax with three wind conditions.
The group "City Street" contains 4 calculation points in a city street environment and includes results of L_Aeq,24h with zero wind.
The group "Yearly Average" contains 4 cases where the yearly average of L_den has been calculated.

The test results have been collected in one Excel spreadsheet for each group.

1 Introduction

The present report contains a number of test cases for which calculations have been carried out by the new Nordic road traffic noise calculation method Nord2000. The model is described in [1], [2], [3]. The test cases have been elaborated to cover most algorithms of the calculation method. The purpose of the test cases is to provide a basis for testing software developed according to the new Nordic model.

The test cases are divided into four groups:

The first group denoted "Straight Road" contains 62 cases for a straight road. The test cases cover most parts of the propagation model with the assumption that the terrain profile perpendicular to the road is constant.
The second group denoted "Curved Road" contains 8 calculation points distributed along a road with two lanes and a turn, looking more like a "real" case. These test cases are based on a former collection of test cases for the old Nordic traffic noise prediction model.
The third group denoted "City Street" contains 4 calculation points. Three of the calculation points are placed in a street with the same traffic flow, but with different contributions from reflections. The last calculation point is placed in a street situated parallel to the street with the traffic flow, but without any traffic itself.
The fourth group denoted "Yearly Average" contains four test cases where the yearly average of the noise is calculated. These cases are based on one of the cases for flat terrain from the group "Straight Road".

The test results have been collected in one Excel spreadsheet for each group.

2 Test Cases for a Straight Road

For a straight road 62 test cases have been developed to test nearly all aspects of the Nord2000 Road Traffic Model.

The horizontal distances in the terrain profile (x-coordinates) perpendicular to the road are measured from the centre line of the road. The road has two lanes, each 5 m wide, and the vehicles are driving in the middle of the nearest lane, and there is no traffic in the far lane.

The vehicles are category-1 vehicles (cars and vans) except in test cases 17 and 18 where vehicles are category-2 vehicles (dual-axle heavy vehicles), and category-3 vehicles (multi-axle heavy vehicles), respectively. In all cases a speed of 80 km/h has been used. The axle width is 1.5 m for category 1 and 2.5 m for categories 2 and 3.

The total length of the road is in all cases 20 times the shortest horizontal distance d_min between the centre line of the road and the receiver point which is placed in the middle. d_min is in all test cases 100 m except in case 16 where d_min is 1000 m. The road is divided into 101 equidistantly placed source points. The distance between the source points is therefore 20 m in all cases except in case 16 where the distance is 200 m.

The results of the 62 cases are given in the Excel spreadsheet "TestStraightRoad.xls" with one worksheet for each test case. An example of a sheet is shown in Appendix A (Test Case No. 1). The main results are:

The sound exposure level L_AE and the corresponding spectrum LE (unweighted) for the pass-by of a single vehicle
The 24-hour equivalent A-weighted sound pressure level L_Aeq,24h and the corresponding spectrum Leq,24h (unweighted) for 10,000 vehicles per 24 hours
The A-weighted maximum level L_Amax
The propagation effect dL (for information, not required in the test process). The propagation effect is the difference between LE and the "free-field" value of LE (disregarding ground and screening effect as well as air absorption).

Besides the results, the sheet contains for each test case the model propagation parameters and the terrain profile given by the distance X from the road centre line perpendicular to the road, the height Z of the terrain, the ground flow resistivity, and the terrain roughness.

The 62 test cases for a straight road can be grouped with respect to the terrain shape as shown in Table 1.

Group 1 (flat terrain) contains test cases with variation in ground impedances, meteorological conditions and vehicle category. The remaining groups represent 11 different geometrical propagation cases, and for each group 4 calculations have been made: downwind, no wind, and upwind, all with a receiver height 1.5 m, and no wind with a receiver height of 4 m.

In group 12 (forest) additional parameters are needed to define the scattering zone which is not included in the information given in Appendix A. The scattering zone parameters are defined in Table 2.

Table 1: Test cases divided into 12 groups.

3 Test Cases for a Curved Road

Ten test cases have been included for the curved road shown in Figure 1. The test cases are based on test cases used for the previous Nordic road traffic model given in [4]. The test cases include 8 receiver positions denoted 1 to 8. For each of the receiver Positions 4 and 5 two test cases have been defined concerning the definition of the thick screen between Positions 4 and 5. In the first case the thick screen is assumed to be a building with vertical facades flat roof and an energy reflection coefficient of 1 (the case numbers are 4-1 and 5-1). In the second case the thick screen is assumed to be an embankment with the same flat top as the building, but sloping faces with a slope gradient of 0.5 (the case numbers are 4-2 and 5-2). The embankment is covered with grass.

The dashed lines in Figure 1 are ground level contours, and the number next to the contour is the ground level in metres. The ground level of the road is 0, i.e. the road is below the terrain surface at Position 1 and elevated above the ground at Position 8.

The road has two lanes, each 5 m wide, and the vehicles are driving in the middle of each lane. The number of vehicles is 10,000 per day, and the traffic is distributed equally on the two lanes. 90% of the traffic is light vehicles (category-1) while 10% is heavy vehicles distributed evenly on category 2 and 3. The speeds of the light and heavy vehicles are 90 and 70 km/h and the axle widths are 1.5 and 2.5 m, respectively. The distance between the source points along the lane is 10 m for receiver Position 5, 25 m for receiver Position 3, and 50 m for the rest of the receiver positions. If the lane is higher or lower than the surrounding terrain, the terrain is decreasing or increasing, respectively, starting at the edge of the lane with a slope of 45° perpendicular to the road.

The receiver distances shown in Figure 1 are measured from the centre line of the road whereas the distances to the screens are measured from the nearest edge of the road. The thick screen at Position 4 is 3 m high and 3 m wide, and the distance from the road edge to the middle of the screen is 10 m. The thin screen at Position 3 is 3 m high, and the distance to the road edge is 5 m.

The road is assumed to be extended infinitely at the lower and upper end in Figure 1.

The coordinates of the objects in Figure 1 (road centre line, barriers, calculation points, terrain lines) can be found in the Excel spreadsheet file containing the calculation results

Figure 1: Plan view of road and surroundings.

Figure 1: Plan view of road and surrounding

The ground surface is assumed to have a flow resistivity of 200 kNsm^-4 (impedance class D) and no roughness (class N). The road surface is assumed to have a flow resistivity of 20000 kNsm^-4 (impedance class G).

The receiver height is 1.5 m except in Position 7 where the height is 3.5 m.

The propagation parameters are:

t₀ = 15°C
RH = 70%
z₀ = 0.05 m
z_u = 10 m
u = 0, and ±3 m/s
φ_u = 315° re north
s_u = 0.5 m/s
Δt/Δz = 0 K/m
s_Δt/Δz = 0 K/m
C_v² = 0.12 m^4/3/s²
C_t² = 0.008 K/s²

The wind direction φ_u = 315° indicates that the wind direction is perpendicular to the upper part of the road. A wind speed of -3 m/s indicates the opposite wind direction (135°). Therefore, 3 m/s indicates downwind in Positions 1, 3, and 4 and upwind in Positions 2 and 5.

The results of the 10 cases are given in the Excel spreadsheet "TestCurvedRoad.xls" with one worksheet for each test case. An example of a sheet is shown in Appendix B (Receiver Position 1). For information, calculation results for light and heavy vehicles separately are given in two extra worksheets for each case.

4 Test Cases for a City Street

Four test cases have been included for city streets. Three of the calculation points (Positions 1-3) are placed in a street with the same traffic flow, but with different contributions from reflections. The last calculation point (Position 4) is placed in a street parallel to the street with the traffic flow, but without traffic itself. The calculation points and the buildings important to the sound propagation are shown in Figure 2.

Figure 2: Plan view of city area.

Figure 2: Plan view of city area

The buildings have flat roofs, and the height of the buildings is 12 m. The coordinates of the buildings, the road centre line, and the calculation points can be found in the Excel spreadsheet file containing the calculation results.

Calculations have been carried out for an energy reflection coefficient of the facades of both 1 and 0.7. The receiver points are placed at the facades (at a distance of 0 m from the surface) at heights above the road surface of 1.5, 4, and 8 m. The sound pressure level at the receiver point has been calculated disregarding the reflection of the facades at the receiver ("free-field" SPL), but including all first and second order reflections from other facades. If the software to be tested cannot ignore the reflection of the facade, the calculated result of this software has to be corrected for the effect of the reflection (-6 dB or whatever reflection effect is applied in the software to be tested).

The road has two lanes, each 6 m wide, and the vehicles are driving in the middle of each lane. The number of vehicles is 10,000 per day, and the traffic is distributed equally on the two lanes. All vehicles are light vehicles (category-1). The speed is 50 km/h, and the axle width of the vehicles is 1.5. The distance between the source points along the lane is 2 m for receiver Positions 1-3 and 20 m for receiver Position 4.

The propagation parameters are the same as used in the "Curved Road" group described in Section 3 except that a wind speed of zero is assumed (u = 0 m/s).

The results of the 4 cases are given in the Excel spreadsheet "TestCityStreet.xls" with one worksheet for each test case. An example of a sheet is shown in Appendix C (Receiver Position 1).

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 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] 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.

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

6 Acceptable Deviation

To check whether a software provider has implemented the Nord2000 prediction method correctly, all the test examples in this report shall be calculated.

The overall A-weighted sound levels (L_Aeq,24h, L_AE, L_Amax) shall not deviate by more than 1 dB from the calculated results in any example specified in the present report. In most cases the deviations can be kept within 0.5 dB. Deviations exceeding 0.5 dB should therefore give rise to increased awareness concerning possible errors in the software under test, and the reasons for the deviation should be explained.

The calculated third octave band spectra shall be compared to the third octave spectra in this report. Deviations less than 1 dB are in general acceptable for the sound level values in each frequency band. Deviations exceeding 1 dB in one frequency band shall be investigated. Special problems may occur at ground effect dips in the frequency spectrum where a shift in the dip may lead to a considerable sound level difference in a frequency band close to the dip. A shift in the dip frequency of one third octave will in general be considered acceptable in such cases.
