Collection and analysis of EDR data from crash involved vehicles
Submission Date: 2019
Event data recorders (EDRs) are installed in many modern vehicles and, in the event of a crash, record driving data such as travel/impact speed, Delta-V and restraint usage. EDR data was collected from 312 crashed vehicles in South Australia during 2017 and 2018, and 238 of these could be matched to police reports. An analysis on speeding and seatbelt usage showed that 27% of free-speed vehicles were speeding and indicated that seatbelt wearing rates in crashes is close to 97%. EDR data provides a more accurate indication of levels of speeding in crashes than available from police reports alone.
