Performance Measures

Preparedness > TIM > Performance Measures

The Traffic Incident Management Performance Measures Focus States Initiative (FSI) involves 11 states that have defined three traffic incident performance measures and conducted field tests of two of these measures. The following measures were defined in December 2005 and field tested for 18 months:

  1. Reduce roadway clearance time
    Defined as the time between first recordable awareness of incident by a responsible agency and first confirmation that all lanes are available for traffic flow.
  1. Reduce incident clearance time
    Defined as the time between first recordable awareness of incident by a responsible agency and time at which the last responder has left the scene.

The third measure that was defined at the final project work shop in October 2007 has not yet been field tested:

  1. Reduce the number of secondary crashes
    Defined as incidents for which a response or intervention is taken, where a collision occurs either a) within the incident scene or b) within the queue (which could include opposite direction) resulting from the original incident.

The FSI represents the first effort by multiple states to measure TIM performance using common performance metrics. The results of the FSI demonstrated that TIM performance measurement is institutionally and technically viable. The participating states also demonstrated that the integration and coordination of TIM operations among multiple agencies can be done seamlessly.

The final products of the FSI are an outreach plan and outreach products that can be used by states to promote TIM PM and integrated TIM programs.
