An Analysis of Speeding-related Crashes: Definitions and the Effects of Road Environments (Nhtsa Technical Report Dot Hs 811 090) U.s. Department of Transportation National Highway Traffic Safety Administration

Speeding is reported in the Fatality Analysis Reporting System (FARS) as a driver-level attribute that combines ?driving too fast for conditions? or ?in excess of posted speed limit.? There is a growing need to parse out these two factors, especially for those designing countermeasures. The report, using data from the State Data System quantifies the extent of these two aspects related to speeding using data from six States whose police accident reports actually parse these out.
