    초록 Railroad is the major factor of vibration source in railway vehicles, and it must carefully maintained the
    original condition to secure the safety and good ride comfort of passenger. Measuring the condition of rail
    irregularities such as surface, alignment, gauge, twist and cant etc is required to maintain the good
    performance of railroad. Currently, the various rail irregularity measurement systems(EM120, ROGER1000K
    and the Total Rail Irregularity Measurement system of Korea High Speed Train) are operated in Korea to
    estimate the rail irregularity. It is hard to verify the correlation of one rail irregularity data of a measurement
    system with the other, because they have been adopted different rail irregularity estimation methods. The best
    method securing the reliability of the irregularity data is the direct confirmation on the ground where the
    measurement system had detected as a fault section, but it is impossible to apply all sections simultaneously
    due to limitation of time, labor, cost and equipments. There is a method to secure the reliability of the data
    by using acceleration values. Rail irregularities, the major factor of vibration in railway vehicle, are
    transmitted to the vehicle acceleration through masses, springs, dampers and joints as the system dynamic
    formation. In this study, Transition Function has been adopted by using the rail irregularity and the
    acceleration value regarding as input & output parameters respectively. It has been verified by comparing the
    analyzed results with real measured irregularity data from the Total Rail Irregularity Measurement system of
    Korea High Speed Train. Also various methods has been accomplished to verify the correlation between rail
    irregularities and acceleration values.
