Event Data Recorders (EDRs) are devices installed on rail vehicles to record specific data such as speed, braking commands, automatic train control information, and operator commands. This project focused on data collected from computers and sensors on board a rail vehicle; video-based EDRs were not considered in this work. The objective of the study was to gather information on current EDR standards and use and to evaluate rail transit industry needs for EDR standards and guidance. Findings of this report and subsequent guidance on standards for EDRs in rail transit can be leveraged to guide public transit agency decision-making. Some findings include the need for a common data format to view EDR data easily by agencies and NTSB investigators and for a written specification explicitly related to rail transit EDR data retention, as states currently have different data retention policies.
The objective of this research project was to evaluate the benefits that Event Data Recorders (EDRs) could provide to transit agencies in three areas:...
