Monitoring study reveals height measurement precision on ballastless track under traffic loading, suggesting essential error confidence intervals for rail diagnostics.
Key Points
To evaluate the precision of vertical and positional geometrical measurements on ballastless railway tracks to establish reliable error confidence intervals under operational traffic loading.
Monitored ballastless track sections on Slovak Railways using periodical diagnostic surveys.
Applied both absolute and relative geodetic measurement methods to assess vertical and positional geometry under traffic loading.
Performed precision analysis on observational height datasets to determine measurement error margins.
Demonstrated that combining absolute and relative diagnostic techniques characterizes track geometry deformation under continuous operational loads.
Established the analytical basis for calculating confidence intervals to quantify height measurement errors on unconventional ballastless track constructions.
