The Dutch National Institute for Public Health and the Environment (RIVM) operates the National Noise Monitoring Network. This network consists of 44 measurement locations alongside motorways and 36 measurement locations near railways. Since 2013, we have used this network to validate the yearly reported noise production levels calculated by the Dutch road and railway authorities. In addition to this validation, the measurements are also used to assess the performance of the Dutch environmental noise calculation method. When necessary, the calculation method is adjusted. The long-time measurements are currently performed with simple dataloggers. These dataloggers were cheap and innovative at the time of installation but are now end-of-life. Besides, the dataloggers have limited recording memory and a limited power supply. The logging interval is low and data retrieval is done physically every two months. With the development of a new system, we will elevate the overall possibilities of the network. An important aspect is remote data retrieval. A challenge is that these loggers must be able to be placed in publicly accessible locations with an independent power supply. This paper will address the results of 10 years of monitoring and further highlight the improvements of the network by the new system.
