Development of Risk-based Railway Track Maintenance Method Using Image Analysis Technology
A hazard sensing technology has been developed for track maintenance that can extract hazard factors related to the expansion of the damage caused by a derailment accident. In addition, a risk-based maintenance method was developed for track irregularity management using the hazard sensing results a...

| description | A hazard sensing technology has been developed for track maintenance that can extract hazard factors related to the expansion of the damage caused by a derailment accident. In addition, a risk-based maintenance method was developed for track irregularity management using the hazard sensing results and a statistical risk model. As a result, it is now possible to extract the factor of magnification of derailment damage (collision with structures and the public, falls from elevated locations) through image analysis using images recorded from the front of commercially operated trains. In addition, a maintenance and management model was created to calculate the appropriate values of the management value of track irregularity and the inspection cycle time, considering the track maintenance cost and the damage scale of the derailment accident. |
