Traffic Incident Management > Clearance & Recovery


Several technologies are available to speed the investigation of incident scenes and record necessary information for later analysis. Temporary traffic control devices help ensure the safety of incident responders and provide for the safe travel of vehicles around the incident site.

When considering the use of camera phones in managing incidents, be aware of the challenges associated with technology interoperability among agencies and first responder priorities.(April 2007)

Draw on the strengths of complementary relationships between the public and private sectors for successful implementation of ITS projects.(August 2006)

Deploy ITS technologies including Computer Aided Dispatch (CAD) and Personal Digital Assistants (PDAs) for dispatchers and responders in traffic incident management.(2005)

Utilize technology sharing and training opportunities to form mutually beneficial relationships for successful incident management programs.(1/1/2004)

Manage resources to optimize incident response and clearance times to reduce the impact on traffic flow.(April 2000)

Utilize well-equipped safety service patrols to assist highway motorists after vehicle malfunctions or crashes, and to coordinate a safe and efficient response.(1/1/1999)

Consider cost-saving strategies and long term needs when making communications investments.(6/1/1998)

Utilize clearance time incentives when contracting with towing service providers to reduce incident clearance times.(5/1/2005)

Combining drone telemetry data with 3-D laser mapping data during the investigation of the Amtrak Cascades derailment reduced police on-scene processing time by up to 80 percent (compared to traditional methods).

A field test of an aerial drone equipped with 3-D imaging technology enabled investigators to reconstruct a crash scene in 25 minutes versus two hours using a conventional method; results suggest clearance times can be cut by more than 50 percent.(09/19/2017)
