Making national international transport system efficient in order meet future demand, solution also complex, as reduction noise emissions will affect many stakeholders. Achieving stated environmental targets depends key criteria-based success factors global efforts. aim study investigate effect quality. Whether innovation activities aimed at reducing related relationship between quality was examined with Panel Threshold Value Regression Model 1979 2019 for selected developed European countries. results show when technologies reduce pass a certain threshold value, impact disappears.
