MAXIMUM VALUE OF TRACK IRREGULARITY

To know maximum values of track irregularities in a certain length of track is necessary for those who maintain track for the safety of traffic and for those who are in charge of maintenance of way. States of track irregularities are represented by the following indexes: P: Index of track irregularity (probability exceeding plus or minus 3 mm) m: Mean value of track irregularities sampled at random sigma: Standard deviation of track irregularities sampled at random. If the mutal relation between the maximum value of irregularity and the irregularity index is ascertained, it will be very useful.
