2019 Traffic Incident Management Capability Maturity Self-Assessment National Analysis Report

Chapter 2. Overview

Ninety-four locations completed a Traffic Incident Management Capability Maturity Self-Assessment (TIM CM SA) in 2019 for inclusion in the national analysis, slightly down from the 98 submitted in 2018. The 55 scored questions in the TIM CM SA were grouped into 3 sections: Strategic, Tactical, and Support. The initial assessments completed in 2003, 2004, and 2005 (78 in total) continue to be used as the Baseline scores, although it should be noted that the Baseline scores are recalibrated each year that a major revision to the TIM CM SA is completed (2007, 2011, and 2015).

The 2019 overall TIM CM SA score was 73.3 percent (out of a possible 100 percent), representing a 44.6 percent increase over the Baseline. The TIM CM SA mean scores tended to be higher in larger metropolitan areas than in smaller areas. Specifically, mean scores were calculated for the top 40 metropolitan areas (by population), the top 75 metropolitan areas, and all other metropolitan areas that responded but were not in either of these groups:

  • Top 40 metro areas: 77.5 percent.
  • Top 75 metro areas: 75.5 percent.
  • Non-top 75: 68.5 percent.
  • Overall: 73.3 percent.

As indicated above, the significant revisions implemented in 2015 resulted in an overall decrease in the national score from 2014 to 2015 (down 9.5 percent). At 73.3 percent, the 2019 score is now the highest since that revision in 2015.
