title = "Optimizing ultrasonic rail defect inspection to improve transportation safety and efficiency",
abstract = "Preventing broken-rail-caused derailments is a high priority for the rail industry and government. The current practice is to periodically inspect rails using non-destructive technologies such as ultrasonic rail inspection. Determining the optimal inspection frequency is a critical decision in railway infrastructure management. The objective of this paper is to develop an analytical framework to address the trade-offs among various factors related to rail defect inspection frequency, in order to maximize rail transportation safety and efficiency.",
