Accident Scene

Traffic Incidents

Why should we address the impacts of Traffic Incidents?

Safety of Responders

Safety Impact

Congestion Impact

For every minute that a freeway travel lane is blocked during a peak travel period, four minutes of travel delay results after the incident is cleared.

Economic Impact

What is a Traffic Incident?

What is Traffic Incident Management (TIM)?

What is Quick Clearance?

Quick Clearanceof a traffic incident is the practice of safely and rapidly removing temporary obstructions from the roadway. Such obstructions include disabled or crashed vehicles, debris, or spilled cargo.

Benefits Of Quick Clearance

Purpose for Indiana’s Quick Clearance

For Indiana to have traffic incident responders, from all disciplines, follow agreed-upon multidisciplinary procedures!

Indiana Impacts:

Emergency Vehicle Traffic Sign

* David Schrank and Tim Lomax, “The 2007 Urban Mobility Report,” Texas Transportation Institute

Urban Area – The developed area (population density more than 1,000 persons per square mile) within a metropolitan region. The urban area boundaries change frequently (every year for most growing areas). The annual change in miles traveled, therefore, includes both new travel due to growth and travel that previously occurred in areas designated as rural.

The Cost of Vehicle Traffic Crashes in Indiana

90 Minutes vs. 75 Minutes Clearance Time: What’s the Value of 15 minutes saved?

On-ramp Truck Wreck

Travel Delay – Travel time above that needed to complete a trip at free-flow speeds. Free-flow speeds (60 mph on freeways and 35 mph on principal
arterials) are used as the national comparison thresholds. Other speed values may be appropriate for specific urban areas.

Annual Delay per Traveler – Extra travel time for peak period during the year divided by the number of travelers who begin a trip during the peak period
(6 to 9 a.m. and 4 to 7 p.m.).

Travel Time Index – The ratio of travel time in the peak period to the travel time at free-flow conditions. A value of 1.35 indicates a 20-minute free-flow
trip takes 27 minutes in the peak.

Excess Fuel Consumed – Increased fuel consumption due to travel in congested conditions rather than free-flow conditions.

Public Transportation – Regular route service from all public transportation providers in an urban area.

Operations Treatments – Freeway incident management, freeway ramp metering, arterial street signal coordination and arterial street access
management.

Congestion Cost – Value of travel delay for 2003 (estimated at $13.75 per hour of person travel and $72.65 per hour of truck time) and excess fuel
consumption (estimated using state average cost per gallon).

Urban Area – The developed area (population density more than 1,000 persons per square mile) within a metropolitan region. The urban area
boundaries change frequently (every year for most growing areas). The annual change in miles traveled, therefore, includes both new travel due to
growth and travel that previously occurred in areas designated as rural.

Spill notification and cleanup-

LE- to call IDEM any time a spill of hazardous cargo is discovered to include the rupture of a fuel tank

LE- Disregard emergency gear enroute to an incident
