TIM teams across the country are beginning to explore measuring
team or "program-level" TIM performance as the only means to improve
multi-agency team response. TIM stakeholders share a common goal
to safely restore the roadways as quickly as possible because this
equates to lives saved:

TIM teams across the country are recognizing that improvements in individual agency TIM operations are helpful, but that to make a real impact responders must work together to assess, identify and act on opportunities for improvement. In short, TIM has become a team sport. TIM teams across the country are increasingly interested in jointly measuring performance as a team to win more resources for TIM.
The biggest barriers to jointly measuring performance of multiagency TIM operations include different definitions for common measures such as "incident clearance time," institutional concerns over data sharing, and incompatible data systems. FHWA's TIM Performance Measurement Focus State Initiative, however, has shown that all of these hurdles can be overcome.Law enforcement, fire and rescue, emergency medical services, and transportation agencies involved in traffic incident management (TIM) share a common goal— restoring the roadways as safely and quickly as possible. They know that every minute of incident delay multiplies traffic queues by a factor of four and increases the risk to responders' and drivers' lives.
FHWA's Traffic Incident Management Program-Level Performance Measurement Focus State Initiative
FHWA launched a focus state initiative in 2005 to develop and test consensus-based, multi-agency, or "program-level" performance measures for TIM. TIM leaders from transportation and law enforcement organizations in 11 states reached consensus on three program-level TIM objectives and associated performance measures for their TIM teams:
TIM Program Objectives | Related Performance Measures |
---|---|
Reduce "Roadway" Clearance Time | Time between first recordable awareness of incident by a responsible agency and first confirmation that all lanes are available for traffic flow. |
Reduce "Incident" Clearance Time | Time between first record able awareness of incident by a responsible agency and time at which the last responder has left the scene. |
Reduce the Number of Secondary Crashes | Number of unplanned crashes beginning with the time of detection of the primary incident where a collision occurs either a) within the incident scene or b) within the queue, including the opposite direction, resulting from the original incident. |
Focus State TIM Performance Measurement Accomplishments

- Achieved landmark agreement on common definitions for three core TIM performance measures.
- Demonstrated that multi-agency data collection and fusion to improve TIM can be accomplished.
- Demonstrated that by working together to measure TIM performance, transportation and law enforcement agencies were able to overcome institutional data sharing hurdles and improved their ability to quantify TIM benefits.
- Helped agencies more effectively build support for their TIM program and win additional funding for TIM technical and resource needs by showing quantified TIM benefits.

Steps to Success
- Recruit agency champions for program-level TIM Performance Measurement.
- Develop a plan, including a plan to exchange needed data between agencies.
- Test the performance measures with available data, manually at first if necessary.
- Identify and plan for any needed system modifications to support data sharing.
- Modify your plan as needed.
- Track your progress on the Road to Success!
