2019 Traffic Incident Management Capability Maturity Self-Assessment National Analysis Report
Chapter 5. Support
The Support section had the second highest overall score of 74.0 percent and the largest increase over Baseline of the three sections (86.4 percent).
The questions in the Support section focused on the tools and technologies enabling improved incident detection, response and clearance. The major revision completed in 2015 removed questions on traveler information, returning the emphasis to the infrastructure and activities that enable incident information exchange between Traffic Incident Management (TIM) program stakeholders. This allows programs to rate their progress on items over which their TIM program has control.
The five questions in the Support section all address TIM data sharing and integration among TIM stakeholders. The highest scoring question in the Support section was question 51 (below), which scored an average of 3.53, the highest scoring question on the 2019 TIM CM SA.
51. Are TIM stakeholders aware of and actively utilizing Traffic Management Center/Traffic Operations Center (TMC/TOC) resources to coordinate incident detection, notification, and response?
Over 61 percent of respondents scored question 51 a 4, indicating widespread understanding and use of TMC/TOC resources for traffic incident management. The comments submitted in the Support section corroborate this, with a number pointing to co-location of public safety and transportation personnel in the TMC/TOC. The locations that scored this question the lowest are in more rural States where traffic management/traffic operation centers are not in place or are not as advanced.
The lowest scoring question in the Support section is question 54 on policies and procedures for signal timing changes to support traffic management during incident response. Question 54 received an average score of 2.37 in 2019 and only 45.7 percent of programs scored this question 3 or 4. The locations that scored question 51 low also tended to score question 54 low, indicating less access to the tools and technologies to support traffic incident management in more rural areas.
Table 12 lists alphabetically the TIM programs that achieved the highest scores in the Support section.
