Shaping complex transport system requires tools supporting decision-making. From the one hand it is necessary to complete needs of transport system users, and from the other reducing the negative impact of transport on the environment. The paper presents an approach to analyze the impact on the designing of sustainable transport system of exhaust emissions in real traffic conditions. The authors show that developing of sustainable transport system will allow for conducting wide research, experimentation and simulation related to distribution of traffic flow on the transport network. Research can be conducted from the point of view three scales: macro, meso and micro. In the paper presents the example of research on this scales.
