Carrier Measure Over Time

Trends
History

This graph displays a carrier’s measure based on 24 months of on-road performance. Zero indicates the best performance. To see how the measure is calculated click here . To see how the measure relates to percentile click here. Expand for more information.

Carrier violations or crashes are weighted by time and severity to produce a measure for that carrier in each BASIC. The measure only considers individual performance based on 24 months of data, with a measure of 0 indicating best performance. The graph below gives a summary of the carrier’s individual performance measure in a specific BASIC over a selected period of time. Select from the drop-down to view this actual performance data along with how this data would appear applying the most recent SMS methodology.
