Traffic Incident Management Resource Management

Summary Information

As part of the Federal Highway Administration (FHWA) campaign to "Keep America Moving," a series of Primers were developed on Traffic Incident Management. The purpose of this guidebook is to:

  • Identify and explore opportunities for improvement in resource management by considering the most efficient and effective use of resources across all responding agencies.
  • Describe potential cost-sharing strategies that would allow these efficiencies to be realized.

Traffic incident management (TIM) requires a coordinated, multi-disciplinary approach, involving law enforcement, fire and rescue, transportation, towing and recovery, and others, to safely and quickly clear a highway incident. Established multi-disciplinary operational training efforts attempt to minimize any inefficiencies or ineffectiveness in response actions by any one agency that may extend the necessary duration of the incident and/or compromise the safety of field personnel or the motoring public. The economic effects of this multi-disciplinary operational approach are most often tied to a reduction in overall incident duration and reported in monetary terms as a reduction in motorist delay, fuel consumption, harmful emissions, and/or secondary incidents involving either other motorists or response personnel.

This same multi-disciplinary approach has not been as widely extended to the area of resource management. To optimize incident management efficiency and effectiveness from a resource management point of view, personnel and equipment should be best matched to tasks based on their respective level of training and/or capabilities. The most efficient and effective use of resources across all responding agencies in combination, economic savings are anticipated and attributable to the:

  • Utilization of personnel who are best qualified (i.e., capable, but not over-qualified) for the various tasks (this, in turn, allows alternately skilled personnel to focus on other incident management functions).
  • Utilization of appropriate equipment by function (i.e., use of the least costly equipment capable of performing the function).
  • Utilization of appropriate technology capable of supporting various on-site resource tasks.
  • Reduction in overall resources required through reduced redundancy across disciplines.

The benefits of multidisciplinary TIM operations are most often tied to a reduction in overall incident duration and reported in monetary terms as a reduction in motorist delay, fuel consumption, harmful emissions, and/or secondary incidents involving either other motorists or response personnel.

FINDINGS

A Case Study in Atlanta, Georgia reported the following benefits:
  • Reduction in Average incident durations from 67 to 21 minutes.
  • Reduction in Vehicle-hours of delay of 7.25 million over one year with an annual cost savings of $152,053,180 (2003 dollars).
  • Reduction in Gasoline and diesel consumption of 5.17 million gallons and 1.66 million gallons, respectively, with a related annual cost savings of $10,365,969 (2003 dollars).
  • Reduction in Harmful emissions of 2,457 tons, 186 tons, and 186 tons of CO, HC, and NOx, respectively, with related annual cost savings of $1,247,985, $15,626,587, and $3,368,436 (2003 dollars).
  • Reduction in Secondary crashes of 69 percent (from 676 to 210 in one year) and a related annual cost savings of $1,611,054 (2003 dollars).
