Presentation on the Nord2000 noise model used in Sweden for road traffic noise mapping. Nord2000 uses five vehicle categories described by weight and number of axles, with 1/3 octave band frequency resolution from 25 to 10000 Hz. Two sources per vehicle category represent rolling and propulsion mechanisms. The model includes surface corrections based on Swedish CPX measurements, horizontal and vertical directivity patterns, and methods for deriving source sound power levels from field measurements using the propagation model with assumed omnidirectional sources.
Agenda for the first regular session of the RUCC Task Force (following the kickoff session held in November 2011).
Adopted minutes from the first technical session of the task force evaluating the certification corridors for the Flex-GTR test tool developed for the GTR on pedestrian safety.
