MEASUREMENT OF THE CARBON MONOXIDE PRODUCED BY VEHICLES IN THE FELBERTAUERN TUNNEL

MESSUNG DER CO-PRODUKTION VON KRAFTFAHRZEUGEN IM FELBERTAUERNTUNNEL

THE PAPER DEALS WITH AN EXPERIMENT TO OBTAIN A RELIABLE VALUE FOR THE CARBON MONOXIDE PRODUCTION OF AN "AVERAGE MOTOR CAR". IN ORDER TO OBTAIN AN AVERAGE VALUE IT WAS NECESSARY TO TAKE MEASUREMENTS ON A NUMBER OF VEHICLES. THE TEST STRETCH USED WAS THE FELBERTAUERN TUNNEL WHICH CONTAINS A PRECISION"ADJUSTABLE HALF CROSS-SECTIONAL VENTILATION SYSTEM. MEASUREMENTS WERE TAKEN DURING THE SUMMER MONTHS OF 1973, DURING WHICH APPROXIMATELY 15000 VEHICLES WERE MEASURED. THE TUNNEL VENTILATION SYSTEM WAS ADJUSTED SO THAT THE STATIONARY POINT OF THE AIR CURRENT IN THE DRIVING SPACE WAS EXACTLY AT THE TUNNEL CENTRE, WHERE THE CARBON MONOXIDE MEASUREMENTS WERE CARRIED OUT. TO RECORD TRAFFIC MOVEMENTS PNEUMATIC COUNTER PADS WERE INSTALLED AT THE NORTH AND SOUTH PORTALS. THE RESULTS INDICATE WITH LOW TRAFFIC FLOW A RELATIVELY HIGH CARBON MONOXIDE PRODUCTION, WHICH IS ATTRIBUTED TO A NON-UNIFORM MANNER OF DRIVING WHEN TRAFFIC IS OF LOW VOLUME. HIGHER TRAFFIC VOLUMES LEAD TO A UNIFORM DRIVING MANNER AND LEAD TO LOWER CARBON MONOXIDE PRODUCTION. UNDER UNIFORM DRIVING CONDITIONS THE MEASUREMENTS AGREED WELL WITH BASIC VALUES FOR CARBON MONOXIDE PRODUCTION RECOMMENDED BY THE SWISS COMMISSION OF EXPERTS.
