RIVM Report 630650001
Along the A2, a new noise measurement series started in June 2010 after the reconstruction due to road widening had been completed. Between 2000 and 2008, the noise levels hardly changed at this location; the road consisted of six lanes with a dense asphalt concrete paving. In 2009, no measurements were conducted at this point because of the extensive road works. In the new situation, the A2 has been widened to ten lanes with double-layer porous asphalt. In this new situation, the noise level dropped considerably because the average distance from the measuring point to the lanes has increased and because of the sound reducing properties of the porous asphalt layer. Along the A12 at Voorburg, a slight increase in noise was measured in 2010. This may indicate a slight deterioration of the porous pavement which dates from 2007. Along the A10-West in Amsterdam, as in 2009, the measured noise level remained the same in 2010.
Setup and purpose of noise monitoring: These are the main results of the Noise Monitoring Program of RIVM for road traffic in 2010. The Noise Monitoring Program follows the trends in road traffic noise at four fixed points: the A2 at Breukelen, the A10-West in Amsterdam, the A12 at Voorburg and the N256 at Colijnsplaat (Zeeland). In addition, noise from rail and air traffic is monitored. For rail traffic, data from two noise monitoring sites provided by ProRail were analysed. The measurements are used to identify trends in noise emissions and to validate Statutory Standard Calculation methods for road- and rail traffic at the measurement sites.
Railways: For railways, the measurements are in line with calculations according to the standard statutory calculation method. For road traffic, the measured values at the N256, as in previous years, are higher than the calculated values.
Pilot aircraft noise: Like last year, this report contains a comparison of measurements of aircraft noise at Zegveld (20 km south of Schiphol airport) with noise data sets from the Integrated Noise Model (INM). INM is used in many studies to determine the noise levels around airports. The measurements in Zegveld are in fair agreement with the noise data from INM.
