The e-POST, an automatic crash notification system for the emergent rescue at auto accident has been launched as a national research program of Korea in 2010. The main research objectives of the e-POST are: 1. Development of algorithm that quantifies crash severity and the prediction of occupant injury risk based on the recorded data in EDR (Event Data Recorder). Utilization of video images of inside and/or outside of the vehicle during (or right after) the event are under consideration. We hope this supplemental visual data can provide additional information for an in-depth analysis of the accident situation. For the injury risk prediction of occupants, virtual simulation using digital human body models will be employed. 2. Selection of communication protocol for the data transmits. Secure data transmit to the rescue center is an important part of the system and it becomes even more challenging issue because the additional video data could be a large size.
