Cargo flow distribution on the transportation network of the national logistic system

The paper presents results of research studies conducted in the Department of Logistics and Transportation Systems at the Warsaw University of Technology Faculty of Transport within the frames of development project of a model of logistics system of Poland in terms of transport co‐modality. The project was realised in the years 2009‐2011. According to increasing road congestion and environmental degradation by transport activities, the methods for rational distribution of the traffic flows in the transport network are sought. The article concerns the issue of rational distribution of cargo flows in the transport network, taking into account the logistical approach to transport tasks. The different variants of traffic distribution with PTV VISUM according to various criteria were presented.
