CONCENTRATION OF EXHAUST FUMES IN RELATION TO THE POSITION OF ROADS AND VEGETATION ALONGSIDE ROADS WHERE THERE IS INTERMITTENT BUILDING

UNTERSUCHUNGEN UEBER DIE ABGASKONZENTRATION IN ABHAENGIGKEIT VON DER LAGE DER STRASSE UND VOM ANGRENZENDEN BEWUCHS BEI LOCKERER ODER ABGESETZTER RANDBEBAUUNG

MEASUREMENTS OF EXHAUST FUMES ARE TO BE MADE WITH RESPECT TO THE FOLLOWING PARAMETERS: HEIGHT OF THE ROAD ABOVE THE TERRAIN; POSITION OF ROAD ALIGNMENT AND INCLINATION OF THE WALLS OF CUTTINGS; DENSITY AND HEIGHT OF VEGETATION NEAR THE ROAD, AND DISTANCE OF VEGETATION FROM THE EDGE OF THE ROAD.
