Vehicle operator performance history recording and reporting systems include devices and methods of automatically collecting and processing vehicle crash or event data over time to form a driver history report. A driver history report may include many factors to express performance or quality of driver service, and these may be reduced to a single value normalized expression in view of a collection of many drivers. Vehicle event recorders are arranged to capture data relating to a particular event. These vehicle event recorders are further coupled to systems which form an association between collected data and the vehicle operator in command of the vehicle at the event moment. Systems provide means for long-term storage of data particularly data in a structure which preserves the association between a driver and event records attributed to him/her. Special recall operations executed against stored data yields operator performance reporting—including a single value performance score indicative of a vehicle operator's performance and safety history. An analyzer system operates to recall data, particularly data from a plurality of events all associated with a single operator but recorded over an extended period of time. Data is arranged such that other mathematical analysis may be applied independently to various data elements or data “fields” to produce performance metrics and ratios which reflect performance. Together, these factors may each be weighted and summed in accordance with specially devised a formulae including those having a single value solution.
