The EMITRANSYS model and the possibilities of its application for the analysis of the development of sustainable transport systems

R. 58, nr 4

The transport system has a direct impact on the economic and socio-economic situation of each country. Planning its development is an important element of policy. Bearing in mind the importance and complexity of this issue, it should be considered using both quantitative methods and mathematical models, as well as advanced simulation tools for modelling transport. The article presents a proposal for an approach to simulation tests of the different transport system in the aspect of the emission of harmful exhaust gas compounds from road transport. The tool for analysing and assessing the functioning of existing or designed systems is a model in which the properties of the real system, which are important from the point of view of the research objective, should be mapped. The Model of Proecological Transport System (MEST) was presented formally as an ordered four. Also elements of optimization taks shaping of proecological transport system in form of datas, decision variables, conditions and goal function were presented. An example of tests on simulation model was shown.

Models of traffic flow distribution for various scenarios of the development of proecological transport system

The paper is a result of a research work concerning the development of an environmentally friendly transport system - Project EMITRANSYS. The publication contains the issues of shaping the transport system, where important factor due to the aspect of sustainable development is including the external costs in transport activity. This paper presents a mathematical model of the distribution of the traffic flow in the transport network. The paper presents selected aspects of the problem of multi-variant distribution of the traffic stream on the network transport for defined scenarios for the transport system development. Traffic distribution on the network has been made due to the criterion function – external cost connected with air pollution. The paper presents modal split of traffic ecological flow for chosen scenarios of the development domestic transport system.

System logistyczny Polski a komodalność transportu

Ambroziak T., Jacyna M.

Logistyka

2011

nr 4

W artykule przedstawiono wybrane efekty prac projektu rozwojowego nt. "Model systemu logistycznego Polski jako droga do komodalności transportu w UE". Wychodząc z pojęcia systemu zdefiniowano elementy Systemu Logistycznego Polski oraz dokonano parametryzacji elementów struktury systemu. Artykuł zawiera sformułowanie matematyczne rozłożenia strumieni ładunków na sieć transportową ze względu na kryterium kosztów.

The article presents selected aspects of the research work "Logistics System of Poland as a way to transport co-modality in UE". The elements of Logistics System of Poland and its characteristics were defined. Article contains mathematical formulation of cargo flows distribution with the criteria of costs minimization.
