Emission factors and emission inventories are an im-portant source of data for compiling and modelling the emissions of traffic in different situations. There is in EU a continuous work and development of emission data inventories, [1–6]. Since the introduction (in 2017) of the road-testing (RDE – real driving emissions) as an obligatory element of the legal testing procedures, the increased amount of RDE-data can be used for different objectives, such as: further development of emission inventories, compliance with “In-Service Conformity” (ISC, EU regulation 2018/1832) and market surveillance activities (EU regulation 2018/858). Extensive activities of testing RDE by means of PEMS (portable emissions measuring systems) have been per-formed in the last years, aiming not only the emissions but also the improvements of instrumentation, of testing procedures and of evaluation [5–17]. A well-known fact is that the emissions at cold start, during the warm-up and at the low speed phases of urban operation, both in the laboratory and on the road, tend to be higher for all pollutants [13, 18–24]. This fact supports even the idea for future introduction of urban emission limits for the short trips, which are very frequent in Europe [5]. In order to enable an automatic co-evaluation of emissions from the special (non)driving situations, the necessary definitions were proposed in the present work. With these definitions, the RDE data of 7 vehicles were processed and the emissions in special driving situations were obtained (part 1). Additionally, some special situations like cold start, warm-up and stop&go were reproduced on the chassis dynamometer with cars of different ages and different tech-nology (part 2). This paper gives some new insights in the topic of emissions from special driving situations.
