There were 12801 road through railroad one-level crossings in Poland in 2018. 215 accidents happened at them in 2018. In order to increase safety in rail and road traffic two-level crossings should be used. They are definitely safer and make the traffic more smooth. In the design and construction of two-level intersections of railway and road or path columns of circular cross-section are often used. They can be successfully replaced by CFFT columns (Concrete-Filled (Fibre-Reinforced Polymer) Tube). The advantage of CFFT columns is the possibility of their widespread use. As the research of these columns shows, including those conducted at the Gdansk University of Technology, they can carry significant compressive loads by their relatively small cross-section. They are resistant to corrosion and protect against corrosion concrete and its reinforcement (if used). In addition, it is worth adding that the electrical resistance of FRP composite is greater than 1GΩ, which is particularly important in the case of electrified railway lines or tram lines.
