MEASUREMENT OF THE BEHAVIOUR OF GROUPS OF VEHICLES IN ROAD TUNNELS FOR THE PURPOSE OF ACCURATE DETERMINATION OF CO EMISSION AND OPTIMIZATION OF VENTILATION FACILITIES

MESSUNG DES FAHRVERHALTENS DES VERKEHRSKOLLEKTIVS IN STRASSENENTUNNEL ZWECKS GENAUERER BESTIMMUNG DER CO-EMISSION UND OPTIMIERUNG DER BELUEFTUNGSANLAGEN

THE MOVEMENT OF A LARGE GROUP OF VEHICLES IN DENSE TRAFFIC CONDITIONS IS TO BE DETERMINED BY MEASURING THE SPEEDS OF TEST VEHICLES IN SEVERAL ROAD TUNNELS. THIS WILL BE FOLLOWED BY DETERMINATION OF CO EMISSION FROM A REPRESENTATIVE GROUP OF 10 - 12 TYPES OF CAR ON A ROLLING TEST RIG IN ORDER TO WORK OUT PRACTICAL CO EMISSIONS FOR A DRIVE THROUGH ROADS AND TUNNELS. THE PURPOSE OF THE WORK IS AN OPTIMIZATION OF VENTILATION PROJECTS.
