RT Journal Article SR Electronic A1 Křečková, Magdalena A1 Krejčiříková, Hana T1 Monitoring of Shallow-Grooved Tramway Crossings JF Communications - Scientific Letters of the University of Zilina YR 2023 VO 25 IS 2 SP D31 OP D38 DO 10.26552/com.C.2023.033 UL https://komunikacie.uniza.sk/artkey/csl-202302-0017.php AB The article presents selected results and the sequencing of research into the project "Long-Term Monitoring of Rail Structures in Tramway Crossings with a Focus on Shallow-Grooved Crossings Aimed at the Optimization of their Maintenance and Noise Reduction", which was running with support from the Technology Agency of the Czech Republic within the Zeta Project (project registration No. TJ04000257) in 2020-2022. The project was elaborated jointly with the Prazska strojirna a.s. Company in cooperation with the Prague Public Transit Company (hereinafter PPTC). The project's objective was to optimize the maintenance of tramway tracks with a focus on shallow-grooved crossings in rail structures taking into account the noise emission levels during the life cycle of these crossings.
