Benefit Estimation of a Lane Departure Warning System based on Reconstructed Accident Scenes

摘要

LDW (Lane Departure Warning system) has started to be introduced in production vehicles, but there is little research on its benefits and limitations so far. In this paper we performed an in-depth analysis compiled by ITARDA (Institute for Traffic Accident Research and Data Analysis) and demonstrated the benefit estimation process. The benefit of LDW is estimated by comparing lane departure events when the vehicle has no LDW, and how they change with the addition of LDW. The analyzed results were used to re-create LDW event using ASSTREET (Advanced Safety System & Traffic REaltime Evaluation Tool). The drivers' responses to the warning were measured in a driving simulator test. The comparison between events with and without LDW clearly shows which cases could be prevented by the use of LDW and the ones that could not be avoided, thereby, providing us with important guidelines to advance the system performance.
