Understanding Death by GPS: A Systematic Study of Catastrophic Incidents Associated with ...
summary
A corpus of 158 news reports yields concrete claims: 52 deaths in 44 incidents and about 64% due to missing or incorrect map attributes. Analysis ties failures to absent physical attributes (road surface, width, clearance), missing space-usage rules, poor map matching and oversimplified audio/visual instructions (18 incidents). Recommendations include delaying geometry imports until minimal attributes exist, using vehicle type and weather-aware routing, reducing map-matching radius on parallel geometries, and flagging complex geographies for richer instructions.
