Abstract
AbstractThis paper presents an optimal track maintenance scheduling model developed for maintaining adequate conditions of the railway tracks and accomplishing an efficient management of the railway service. Our model has been used in several major Japanese railway companies to develop optimal track maintenance schedules (OTMS). Since train accidents cause enormous losses (not only for the railway company but also for society), we propose to take into account the risk of train accidents while developing the OTMS. Thus, it is critically important to identify measures to quantitatively evaluate the risk of accidents to ensure safe and stable transportation. We propose a method to estimate track maintenance costs and the related costs associated with the risk of train derailment due to longitudinal level irregularities of the railway track. We attempt to show a desirable condition of railway tracks by applying the accident cost estimation method and the OTMS model to an actual railway section. We also demonstrate how to apply these models to actual railway networks in general by validating the estimation results using actual numerical data.
