Railway Engineering
Research issues in the field of railway engineering focuses on problems related to the railway superstructure, especially its planning, design and maintenance. The following issues are investigated: structure of the railway track and its durability and reliability, analysis of geometric layouts with the use of modern satellite and inertial positioning techniques, diagnostics and maintenance of railway infrastructure, studies of the impact of railway transport on the environment - mainly vibrations and noise, urban rail transport - planning and safety assessment, intermodal transport issues. The above areas are investigated with the use of the field measurements and observations, as well as with the use of theoretical models and algorithms for processing measurement signals.
