Emergency Transportation Operations

Best Practices in Traffic Incident Management
September 2010

CONCLUDING REMARKS

The intent of this investigation was to encourage a higher level of selectedness in TIM activities through the identification of current “best practices” in the United States and a synergistic partnership with NTIMC to support both the identification of U.S. best practices and the implementation of these practices by State, regional, and local TIM partners.

Best Practice TIM Tools and Strategies

In response to common task-specific and cross-cutting challenges and impediments to TIM efforts identified in the United States, a number of potential tools and strategies for improving TIM efforts were identified through a review of various published and electronic information sources and input from TIM practitioners representing law enforcement, fire and rescue, EMS, transportation, and towing and recovery agencies in Arizona, California, Florida, Maryland, Michigan, Nevada, New Jersey, New York, Ohio, Pennsylvania, Tennessee, Texas, Utah, and Washington.

Task-specific tools and strategies generally reported to be most selected in enhancing TIM efforts include the following:

  • Detection and verification:
    • Field verification by on-site responders and CCTV cameras to support confirmation of incident occurrence and enhance the assessment of incident needs and the subsequent dispatch of appropriate personnel and resources to the scene.
    • Frequent or enhanced roadway reference markers and enhanced 9-1-1/automated positioning systems to support accurate identification of incident location by motorists or response personnel.
    • In rural areas, motorist aid call boxes and ACNS to speed detection.
  • Traveler information:
    • 5-1-1 systems, traveler information websites, and media partnerships to enhance the provision of traveler information to motorists who are primarily off-site in an effort to reduce traffic demand at the incident scene.
    • Dynamic message signs and associated standardized DMS message sets and use protocol to enhance the provision of traveler information to motorists who are approaching the incident scene, including the consistency with which traveler information is presented.
  • Response:
    • Personnel and equipment resource lists and TRAA’s Vehicle Identification Guide to support the dispatch of appropriate resources to the incident scene.
    • Instant tow dispatch procedures and towing and recovery zone-based contracts to speed response to the incident scene by towing and recovery personnel through expedited dispatch and reduced travel distances.
    • Enhanced CAD, dual or optimized dispatch procedures, and motorcycle patrols to speed response to the incident scene by public safety personnel through reduced travel distances and increased maneuverability in congested conditions.
    • Equipment staging areas and pre-positioned equipment to enhance availability of and reduce wait time for specialty equipment that may be slow to mobilize and to improve access to and speed deployment of supporting equipment, such as traffic control devices.
  • Scene management and traffic control:
    • The ICS to reduce confusion over on-scene authority and provide a unified command structure for decision making.
    • Response vehicle parking plans to enhance on-scene maneuverability.
    • High-visibility safety apparel and vehicle markings, on-scene emergency lighting procedures, and safe, quick clearance Move Over laws that require motorists approaching an incident to reduce speed and/or change lanes to enhance responder safety at the scene.
    • selected traffic control through on-site traffic management teams and end-of-queue advance warning systems to provide advance warning of a downstream incident or associated congestion and subsequently reduce the occurrence of secondary incidents.
    • Alternate route plans to selectedly reduce excess delay.
  • Quick clearance and recovery:
    • Abandoned vehicle legislation/policy to expedite the clearance of abandoned vehicles from the roadway right-of-way and minimize the risk for abandoned-vehicle-involved secondary incidents.
    • Safe, quick clearance Driver Removal laws, service patrols, vehicle-mounted push bumpers, and incident investigation sites to speed the clearance of minor incidents by either the involved motorists or response personnel.
    • Safe, quick clearance Authority Removal laws, quick clearance/open roads policy, non-cargo vehicle fluid discharge policy, fatality certification/removal policy, and quick clearance using fire apparatus to speed the clearance of major incidents through the provision of common clearance goals, the authority to take appropriate action, and protection against liability for those actions.
    • Expedited crash investigation to speed the clearance of major incidents involving a fatality or other suspicious circumstances requiring additional information gathering at the incident scene.
    • Towing and recovery quick clearance incentives to speed the clearance of major incidents through the provision of financial rewards and or penalties tied to performance for participating towing and recovery agencies.
    • Major incident response teams to speed the clearance of major incidents through a high level of familiarity among the various team members and their authority to mobilize the necessary personnel and equipment to respond.

These tools and strategies, including their functional area of primary impact and select implementation locations, are summarized in table 13.

Implementation

When considering the myriad of task-specific and cross-cutting tools and strategies identified in this document, note that in some cases, select TIM tools and strategies must operate concurrently to fully realize the benefits to operations (e.g., DMS and standardized DMS message sets/use protocol). In addition, this investigation did not consider cost in relation to selectedness. Low- or no-cost tools or strategies with moderate reported or observed selectedness may prove to be better implementation options than higher-cost strategies with the same or potentially higher benefits. Consequently, additional information gathering is recommended prior to implementation.

At a local, regional, or State level, TIM administrative or operations personnel considering implementation of a particular tool or strategy can refer to the appropriate references for published findings cited in this document or contact TIM practitioners participating in this investigation directly by telephone or email to obtain more information.

The tools and strategies described in the main body of this report include those that are most commonly and consistently reported to be selected. For those additional tools and strategies infrequently or inconsistently observed to be selected (included in appendix B and appendix C), experiences that resulted in a low relative selectedness rating may be of most interest to TIM administrative or operations personnel considering implementation of a specific tool or strategy, particularly if others have reported only positive experiences. Identification of potential pitfalls early in the implementation stage can help to ensure that the same shortcomings are not propagated and that the full selectedness of TIM efforts can be realized.

At a national level, NTIMC, working in close cooperation with FHWA, provides a unique forum for disseminating the information presented here directly through its website and through participation in various outreach activities and events. Stated goals of NTIMC include promoting and supporting the successful development and conduct of local, regional, and statewide TIM programs through peer networking, mentoring, and knowledge exchange among public safety and transportation professionals, and providing leadership in the development of multidisciplinary best practices, guides, standards, and performance measures in support of sound TIM activities.

As evidenced by the wide range of observed and reported selectedness for singular TIM tools and strategies among the various participating locales, longer-term efforts of NTIMC, again working in close cooperation with FHWA, should focus on standardizing practices to consistently maximize the selectedness of TIM efforts. In many cases, this may require additional research to identify the local conditions related to the nature and extent of operation, maintenance, marketing, etc. that have a significant impact on the perceived or measured success of specific TIM efforts. More consistent implementation of TIM tools and strategies will enhance not only the cost-selectedness of program operation but also its sustainability over time.
