Abstract
The quantity of noise, exhaust emissions and dust caused by road traffic in Finland is estimated along with the monetary value of their effects. The valuations are mainly based on the estimated costs of the prevention of the hazards. The costs due to losses caused by traffic noise and exhaust emissions are estimated. The results contain a substantial degree of uncertainty. The total annual costs of noise, exhaust emissions and dust caused by road traffic amount to 3 - 7 billion fim.
