sonROAD18 is a Swiss road traffic noise emission model based on CNOSSOS-EU formalism, covering more than 10 vehicle categories with speed ranges 20-130 km/h, calibrated using over 700,000 pass-bys from 2015-2017. NExUS is a research model for noise from battery electric and internal combustion engine passenger cars during acceleration in urban scenarios, based on more than 3,000 real drive trajectories recorded in 2024, with speed ranges 0-60 km/h. Both models predict noise emissions via propulsion and rolling noise components using three octave bands.
