The aim of the project is to collect information and process resources for analysis, on the basis of which it will be possible to make strategic decisions and plans in the context of introducing low-emission rail transport with a focus on so-called BEMU vehicles (combined trolley and battery power supply). Approximately 15 railway lines will be analyzed, and on each of them, the suitability of the potential deployment of BEMU or EMU vehicles will be compared with the current situation, i.e., the operation of DMU vehicles. The planned analyses will take into account all key impacts, primarily economic (financial accessibility, economic efficiency), environmental (energy and emission intensity and other negative impacts on the environment throughout the entire life cycle), energy (impact on the traction and power supply system), infrastructure (dimensioning of the TNS, definition of sections for the construction of traction lines), and transport (track capacity, travel times), which will contribute to the effective implementation of low-emission vehicles on the Czech railway network.
From the above, it is clear that the project's objectives are aimed at supporting a competitive railway transport system in the Czech Republic, particularly in terms of introducing possible applications of acute-trolley vehicles in synergy with the railway power supply system and dependent electric traction. The practical application of the results will enable the fulfillment of the commitments set out in the strategic documents of the EU and the Czech Republic in the areas of transport, energy, and the environment. At the same time, this will reduce the negative impact of transport on the environment and accelerate technological development in the Czech Republic to meet the social need for environmentally friendly transport.
The specialized map will show the differences between the current and potential future status when low-emission technologies are introduced on individual routes in the Czech Republic. The map will serve as a suitable tool for simple and clear interpretation of the findings concerning infrastructure and vehicle energy outputs, the economics of the proposed solutions, and, last but not least, a comparison of the energy requirements and emission impacts of the analyzed drive solutions.
Cost-benefit analysis will enable the appropriate assessment of the overall social impact of the implementation of new technologies and is key to a comprehensive understanding of the implementation of low-emission technologies in the context of transport, transportation, environmental, and overall social impacts.
Life cycle analysis will be used to compare the environmental impacts of combustion, electric, and acoustic vehicles throughout their entire life cycle. This means during the production, operation, and disposal (recycling) phases. The analysis will be processed in impact categories defined by the Environmental Footprint methodology. The impact on the climate will be determined taking into account existing projections of specific greenhouse gas emissions from electricity production in the Czech Republic.
The core of the software will be detailed models of electric and acoustic vehicles and detailed track parameters. The software will enable the simulation of journeys with the quantification of time sequences of traction and energy variables. An add-on module will concentrate the results of individual vehicle journeys into a simulation scenario in terms of area and time, calculating energy ratios in the traction network. The software will also support the implementation of 25 kV, 50 Hz converter power supply, including modeling and tuning of converter output characteristics.
This is a special module designed for the experimental analysis of LTO traction battery cells, primarily at the level of circuit model parameterization and quantification of the effects on these parameters (e.g., temperature, depth of discharge, instantaneous power). The module will include a power section with LTO cells (specific for railway applications), battery management, and computational software support for processing measured data. The module will be designed for testing in the laboratory or on experimental vehicles.
This project, Determination and optimization of vegetation strips with natural tree species composition for traffic noise reduction, is co-financed with state support from the Technology Agency of the Czech Republic and the Ministry of Transport of the Czech Republic under the TRANSPORT 2030 Program. This project is financed under the National Recovery Plan from the European Recovery and Resilience Facility.
