Making the Connection: Advancing Traffic Incident Management in Transportation Planning

Appendix A. Regional TIM Planning Sheets

This section of the primer provides one- to two-page information sheets that group together similar TIM objectives under major categories of outcomes related to system performance or operations activities. The purpose of these sheets is to give planners and TIM professionals tangible examples of TIM objectives that can be drawn from, in whole or in part, to develop metropolitan transportation plans or related operations or TIM-focused plans. The sheets contain sample TIM objectives, performance measures, data required, and sample TIM strategies that may be considered to meet the objectives. In addition, any known safety impacts that may be realized through the use of the sample TIM strategies are noted.

Responder and Motorist Safety
General Description The focus of these objectives is on improving the safety of traffic incident responders at the scene and in transit to and from the scene and motorists involved in the incident.  
Operations Objectives
  • Reduce responder stuck-by incidents by X% from this year's level by 2015.
  • Decrease responder traffic incidents going to or from incident scenes by X% from this year's level by 2015.
  • Reduce the total number of responder fatalities for the next 5 years by X% of the previous 5-year total.
  • Increase the percentage of accident victims who survive traffic incidents. 
Performance Measures
  • Number of traffic incident responder struck-by incidents per year.
  • Number of responder incidents occurring while in transit to and from incidents scenes per year.
  • Number of responder fatalities during incident response over 5 years.
  • Percent of accident victim survival.
Anticipated Data Needs Responder safety incident records including stuck-by incidents, responder traffic incidents, and responder fatalities. Accident victim survival rates.     
Data Resources and Partners
  • Safety and incident reports from TIM responder agencies and partners including police, fire/EMS, towing, HAZMAT, DOTs, and others.
  • Survival/fatality reports from hospitals and coroners.
Management and Operations (M&O) Strategies to Consider

The National Unified Goal recommends several strategies to improve responder safety.  They include:

  • "Recommended practices for TIM responder safety and for traffic control at incident scenes should be developed and widely published, distributed, and adopted."
  • "Driver training and awareness programs should teach drivers how to react to emergencies on the roadway in order to prevent secondary incidents, including traffic incident responder injuries and deaths."
  • "TIM responders should receive multidisciplinary National Incident Management System (NIMS) and Traffic Incident Management training."

In addition, improve awareness and compliance with Move Over/Slow Down laws. Each State now has some type of Move Over/Slow Down law that requires drivers to move over or slow down when approaching traffic incident response vehicles and traffic incident responders on the roadway.

M&O strategies that support quick incident detection and response by trained medical staff should improve survivability rates for motorists involved in incidents.

Safety-related Impacts Direct safety impacts not identified within referenced safety documents.



Secondary Incidents
General Description

The focus of these objectives is on the reduction of secondary incidents, which are incidents that result from an initial incident.  Motorists moving through and upstream from a traffic incident site are vulnerable to secondary incidents caused by sudden slowing of traffic, lane changes, and the situation or movement of emergency vehicles.  A nationally accepted definition of secondary incidents does not yet exist.  

An initial definition from the 2009 Federal Highway Administration Focus States Initiative: Traffic Incident Management Performance Measures Final Report is "Unplanned incidents (starting at the time of detection) 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 the opposite direction) resulting from the original incidents."

Operations Objectives
  • Reduce the number of secondary incidents occurring each year by X% over this year.
  • Reduce the severity of secondary incidents such that the percentage of secondary incidents that are fatal or injury-causing decreases by X% within X years.
Performance Measures
  • Beginning with the time of detection of the primary incident, the number of incidents that occur either a) within the primary incident scene or b) within the queue—including a queue in the opposite direction—resulting from the original incident. (FHWA Focus State Initiative)
Anticipated Data Needs
Data Resources and Partners
  • Traffic management center, State/local DOTs, State and local police.
M&O Strategies to Consider
  • Safety service patrols (provide traffic control at scene) http://www.safehighways.org/safe-highway-matters/spring-2010-3/secondary-incidents/
  • Traveler information on alternate routes
  • Policies and procedures for HAZMAT and fatal incidents that also include maintenance of traffic flow
  • Strategies that reduce time to clear incident scene, including the use of CCTV cameras to support incident detection and verification, 511 systems, dynamic message signs, towing and recovery quick clearance incentives, incident command system, and others.
Safety-related Impacts Direct safety impacts not identified within referenced safety documents.



Incident Detection and Verification
General Description This set of objectives focuses on improving the detection and verification of an incident, the first   steps in the TIM process. Detection is the determination that an incident of some type has occurred. Incidents may be detected in person by motorists or response personnel or automatically using electronic loop detectors and associated incident detection algorithms. Verification is the determination of the precise location and nature of the incident, which may be performed by on-site response personnel or CCTVs.
Operations Objectives
  • Reduce mean incident notification time (defined as the time between the first agency's awareness of an incident and the time to notify all needed response agencies) by X percent over Y years.
  • Decrease the average time for incident verification by X percent by year Y.
  • Reduce the number of times that inaccurate incident location and type information are provided to response personnel during notification to X inaccurate notifications per month.
Performance Measures
  • Average incident notification time of necessary response agencies.
  • Average time for incident verification (defined as the time between the first agency's awareness of an incident and the determination of the precise location and nature of the incident).
  • Number of inaccurate notifications to response agencies per month regarding incident location and type.
Anticipated Data Needs
  • Time of awareness of incident by first agency.
  • Time of notification to all necessary response agencies.
  • Time of incident verification.
  • Accuracy of incident notifications.  
Data Resources and Partners
  • Data would need to be tracked by the incident responders or operators at a traffic management center or emergency operations center with access to video of the scene.  The partners needed for these measures would be all incident responders willing to support the objectives.
M&O Strategies to Consider M&O strategies to consider in improving detection and verification of incidents include enhancing inter-agency voice and data communications systems, expanding the use of roving patrols, and CCTV cameras.  Accuracy of incident notifications can be improved through 1/10 or 2/10 mile markers and motorist call boxes in rural areas.
Safety-related Impacts Direct safety impacts not identified within referenced safety documents.



Incident Response
General Description This set of objectives focuses on improving incident response: "the activation of a 'planned' strategy for the safe and rapid deployment of the most appropriate personnel and resources to the incident scene."21
Operations Objectives
  • Reduce mean time for needed responders to arrive on-scene after notification by X percent over Y years.
  • For X% of all HAZMAT incidents, the necessary HAZMAT equipment and personnel arrive on scene within X minutes of notification.
  • For X% of all incidents requiring tow trucks, the appropriate tow truck equipment arrives on scene within X minutes of request.
Performance Measures
  • Mean time for needed responders to arrive on-scene after notification.
  • Time for necessary HAZMAT equipment and personnel to arrive on-scene following notification of a HAZMAT incident.
  • Time between request for tow trucks and the arrival of appropriate tow trucks on scene.
Anticipated Data Needs
  • For each incident of interest in the region, incident notification time and on-scene arrival time. 
  • For all HAZMAT incidents, the time of notification to HAZMAT staff/agencies and the arrival time of necessary HAZMAT equipment and personnel.
  • For incidents requiring tow trucks, the time of tow truck request and the time all appropriate tow truck(s) arrive on-scene.
Data Resources and Partners
  • Data would need to be tracked by 9-1-1 dispatchers, incident responders on scene, or operators at a traffic management center or emergency operations center with access to video of the scene. 
M&O Strategies to Consider M&O strategies to consider in improving the timely and optimum response of personnel and equipment to incident scenes include enhancing inter-agency voice and data communications systems, CCTV cameras, pre-positioned tow trucks, towing and recovery zone-based contracts, enhanced computer-aided dispatch that uses automated vehicle location systems, and emergency vehicle preemption at traffic signals.
Safety-related Impacts

Select examples of associated M&O strategies and their safety impacts include:

  • Employ emergency vehicle preemption: The safety impact is the potential for decreasing response times. Reviews of systems in several cities show a decrease in response times ranging from 14 to 50 percent.  Source: NCHRP 500 Volume 12 (effectiveness categorized as "proven").
  • Install emergency vehicle preemption systems: The crash modification factor (CMF) for this treatment is 0.30 for all crashes. Source: FHWA Desktop Reference for Crash Reduction Factors, 2008.
    Note: The existing number of crashes is multiplied by the CMF to determine the number of crashes that may be anticipated following implementation of a treatment.



Incident Scene Management and Traffic Control
General Description This set of objectives focuses on the coordination and management of resources and activities at or near the incident scene, including personnel, equipment, and communication links.  It also features safe and efficient management of traffic approaching the scene. This phase of TIM occurs once incident response agencies have arrived on the scene.

  • Response vehicle placement and on-scene emergency lighting procedures will be developed and used for all traffic incidents in the region by year Y.
  • The Incident Command System, a well-established, standardized on-scene process for managing incident response activities, is understood by all incident response personnel prior to performing incident response functions and is used at all incident scenes by year Y.
  • The region develops and uses specific, mutually agreed upon policies and procedures for HAZMAT and fatal accident response that also address maintaining traffic flow around the incident by year Y.
  • By year Y, alternate route plans have been established and used by all appropriate agencies in the region for all routes with average daily volumes exceeding X.
Performance Measures
  • Rate of use of MUTCD-compliant Traffic Incident Management Areas.
  • Rate of use of response vehicle placement and on-scene emergency lighting procedures.
  • Percent of incident response personnel demonstrating proficiency in Incident Command System concepts and process.
  • Rate of use of the Incident Command System.
  • Usage rate of policies and procedures for HAZMAT and fatal accident response.
  • Percentage of routes in region with average daily volumes over X with alternate route plans.
  • Rate of use of alternate route plans.
Anticipated Data Needs
  • Usage rates for the procedures and policies listed in the performance measures. 
Data Resources and Partners
  • Data would need to be tracked by the incident responders or operators at a traffic management center or emergency operations center with access to video of the scene.  The partners needed for these measures would be all incident responders willing to support the objectives.
M&O Strategies to Consider M&O strategies that support this set of objectives include multi-agency training and regional TIM programs. Other M&O strategies are inherent in the operations objectives.
Safety-related Impacts Direct safety impacts not identified within referenced safety documents.



Incident Clearance and Recovery
General Description This set of objectives focuses on the final steps of the TIM process: incident clearance and the recovery of the roadway. "Clearance refers to the safe and timely removal of any wreckage, debris, or spilled material from the roadway. Recovery refers to the restoration of the roadway to its full capacity."22 This set also includes objectives that account for the entire duration of the incident
Operations Objectives
  • Reduce mean incident clearance time per incident by X percent over Y years. (Defined as the time between awareness of an incident and the time the last responder has left the scene.)
  • Reduce mean roadway clearance time per incident by X percent over Y years. (Defined as the time between awareness of an incident and restoration of lanes to full operational status.)
  • Reduce mean time of incident duration (from awareness of incident to resumed traffic flow) on transit services and arterial and expressway facilities by X percent in Y years. 
Each objective can be qualified for the level of traffic incident (major, intermediate, and minor) as defined in MUTCD, Chapter 6I, Control of Traffic through Traffic Incident Management Areas.  Major traffic incidents are those that typically require closing all or part of the roadway for a period exceeding 2 hours. Intermediate traffic incidents are those that typically affect travel lanes for a period of 30 minutes to 2 hours. A minor incident typically lasts no more than 30 minutes and does not require lane closures or extensive traffic control.23
Performance Measures
  • Mean incident clearance time per incident.
  • Mean roadway clearance time per incident.
  • Mean time of incident duration
Anticipated Data Needs
  • Data needed for these measures include the time of the awareness of an incident and one or more of the following pieces of data: the time the last responder left the scene, the time when all lanes were re-opened, the time when traffic returned to full operational status.
Data Resources and Partners
  • Data would need to be tracked by the incident responders or operators at a traffic management center or emergency operations center with access to video of the scene.  The partners needed for these measures would be all incident responders willing to support the objectives
M&O Strategies to Consider

M&O strategies to consider in improving incident clearance and recovery include all of the strategies suggested for the areas of detection and verification, incident response, and incident scene management and traffic control. Policies and laws to consider for improved incident clearance include abandoned vehicle legislation/policy, safe, quick clearance laws—driver removal and authority removal, quick clearance/open roads policy, fatality certification/removal policy, and non-cargo vehicle fluid discharge policy.24 Expedited crash investigation methods such as photogrammetry.
