The inspection frequency for vehicles is determined based on deterioration or damage caused by distance or time. Distance-related factors typically include components such as bogie frames and wheel axles. Bogie frames are generally designed with a passenger load of 250% capacity. However, if the inspection frequency is evaluated assuming 250% capacity for the entire period, it is expected that the evaluation will be excessively conservative. Therefore, a more appropriate evaluation requires an understanding of the actual distribution of ridership (i.e., the distribution of vehicle mileage relative to passenger congestion levels). This study focused on estimating the vehicle mileage for each congestion level, which was calculated by time of day for a specific section in an urban area based on station congestion data. Additionally, the estimated results are discussed for each operating/running condition.
