Performance Measures 

Collection and tracking of incident information is essential to measuring the success of the TIM program, and addresses several of the Objectives adopted by the ME/NH TIM Committee listed below:

Objective One – Increase responder safety by eliminating struck-by incidents, injuries, and fatalities

Objective Two – Minimize impacts to the free flow of traffic

Objective Three – Decrease incident clearance time

Objective Four – Decrease secondary incident occurrences

Objective Five – Improve inter-agency communication during incidents

The collection of performance measures information also fits into efforts on the State and Federal level.  In 2007, the Federal Highway Administration (FHWA) convened 11 states through its Focus States Initiative (FSI) to develop, implement and test TIM performance measures.  This two-year effort, completed in January 2009, resulted in three national-level TIM program objectives and supporting performance measures defined as follows:

  • Reduce “roadway clearance” time: the time between the first recordable awareness of an incident (detection, notification or verification) by a responding agency and first

        confirmation that all lanes are available for traffic flow.

  • Reduce “incident clearance” time: the time between the first recordable awareness of the incident and the time at which the last responder has left the scene.

  • Reduce the number of secondary incidents: the number of unplanned incidents

        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.
