Aim of the investigation, phase I, was: Determination of the for the total investigation needed representative selection vehicles (engines) and the ascertainment of the vehicle specific data, which are needed for the calculation of the exhaust emission of the vehicles with values out of the engine-performance-graph. Statement of the traffic specific data, which are needed for calculation of environmental pollution by roadway traffic with commercial vehicles, as far as suitable informations are available. With help of the stock structure the population of the commercial vehicles, which must be taken into consideration, and its distribution on the traffic kinds, professional goods traffic, work traffic, were investigated. For the selection of the representative vehicle types beside the stock also engine- and traffic - specific points were taken into consideration. To take the traffic specific influence on the exhaust emission into consideration, the effects of transport and driving of the montioned traffic kinds were investigated, whereby also the operation with trailers was included. At last the question of suitable driving cycles or velocity distributions was treated shortly. (orig.) With 13 refs., 31 tabs., 1 annex.
