Title: Traffic Crash Investigation and Traffic Incident Management
1Traffic Crash Investigation and Traffic Incident
Management
2What is Traffic Incident Management?
- Traffic Incident Management is the process of
coordinating the resources of different
partnering agencies and private sector companies
to identify, respond to, and clear traffic
incidents as quickly as possible while protecting
the safety of on-scene responders and the
traveling public.
3Why do we need it here?
- Metro area growth has resulted in increased
traffic volume and congestion - To accommodate traffic volume shoulders have been
reduced and / or eliminated in lieu of additional
travel lanes
4Related Problems
- Kansas City is second only to New York City when
it comes to incident related traffic congestion - Higher number of secondary collisions and
incidents - For every minute traffic is shut down on a busy
highway the traffic jam builds one mile.
5Related Problems
- Economic Impact FHWA has translated the average
20-minute lane blockage into a monetary figure to
show how freeway incidents directly affect the
national economy. If one lane of a three-lane
freeway is blocked for 20 minutes assuming the
freeway is running at capacity the delay caused
to motorists will exceed 1,200 vehicle hours. At
the FHWA-assigned value of 4.00 per hour for
each vehicle hour of delay the cost of the
incident due to the delay alone is approximately
5,000.00 - Increased Pollution
6Missouri Traffic Incident Management Summit Sept.
2007
- National Overview FHWA and NTIMC
- Nature of Problem from Safety and Congestion
Standpoint - Law Enforcement TIM Practices and Challenges
- MODOTs Perspective
7What is the Traffic Incident Management
National Unified Goal?
- Responder Safety
- Safe, Quick Clearance and
- Prompt, Reliable, Interoperable Communications.
8State Regional TIM Program Elements
- Strategic Program Plans
- Partnership Agreements MOUs
- Emergency Transportation TIM Operations
Response Plans - Guidelines Laws Scene Management Guidelines,
Move Over, Steer It/Clear It, etc. - Services Motorist Assist Patrols, Reconstruction
Teams, Traffic Management Teams, etc.
9TIM Summit OutcomeGoals and Objectives
- MUTCD Compliance, reflective garments, signage
- Quick Clearance 90 minute Target
- MODOT Promises Assistance and Support recovery
and clean up, traffic control, - Treat Highway Crash Scenes as temporary work
zones
10What if?
11Sometimes You Have No Choice The Road Must Be
Closed, But
- Closed Closed
- Closed Does Not Safe
- Adequate Resources Needed For Safety (District
Officers, Traffic Crews, Personnel from other
zones, MODOT, Signs, etc.)
12Putting It Into Perspective
- The longer an incident is in place, the greater
the risk for secondary collisions. - and
- The longer incident responders are vulnerable,
and exposed to chance of injury.
13Increased Risk to Responders
14Increased Risk to Citizens
15Improper Traffic Control
16Proper Traffic Control
17The KCPD Experience
18KCPD Prior to 2007 TIM Summit
- Priority was on conducting the investigation with
no consideration given to implications of a
complete highway shut down, or emphasis on
clearing the roadway. 4 to 6 hours not uncommon. - Relied on traffic enforcement crews with many of
them being on motorcycles or district officers to
handle traffic control
19KCPD Prior to 2007 TIM Summit
- At the mercy of tow companies to clean up scene.
No control over the time or method of recovery. - Less than optimal working relationship with KCFD.
- Poor Communications Internal and External
- Did not use available resources to advantage.
20KCPD Prior to 2007 TIM Summit
- Lacked efficient scene management (No Plan)
- Typically would not call Medical Examiner until
after everything was done - Typically would not call for tow trucks until
after everything was done - Did not play well with others
21KCPD Prior to 2007 TIM Summit
- Began using total stations in 2001 purchased with
MCSAP and Grant Funds - Only 2 of the 4 Total Stations used by VCS
personnel had reflector-less measuring
capability. (Required officer with prism pole in
the roadway to take measurements.) - As a unit did not use technology to advantage
- Different levels of competence with equipment.
- Responding personnel did not function as a team.
22Total Station (Survey Instrument) used to Measure
Scenes by VCS Personnel
23KCPD Commitment 2007 TIM Summit
- Chief Corwin supports the Traffic Incident
Management program as long it does not compromise
the integrity of an investigation by our agency,
or jeopardize the safety of our personnel. -
24After the Summit
- A New Beginning
- 720 Squad Test Case
25The Crash Team Concept
- Many agencies have established Crash Teams but
what does this really mean? - Is it anything more than just a title?
26To be Effective The Crash Team
- Must really function as a team
- Organized, coordinated team approach to scene
investigation - Divide and share responsibilities
- Have a plan
- Set goals and objectives, targeted results
27MODOT Assistance
- Traffic Control, Manpower, Resources, cones
- Incident Warning Signs
- Provided equipment (2 new reflector-less total
stations, new digital cameras and flashes)
28VCS 720 Squad
- Sgt. Bill Mahoney 720
- PO Bill Johnson 721
- PO Paul Luster 722
- PO Ron Reilly 723
- PO Jamie Lamb 724
29KCPD 720 Squad
- Functions as a team
- Supervisor is more of a coordinator
- Lead Officer handling crash usually dictates
roles of other team members - All members work in concert to accomplish goals
- Limiting the time a roadway is closed is now
factored into action plan. The target is 90
minute clearance.
30Shared Responsibilities
- Gather Information, vehicle, witnesses, etc.,
- Photographs
- Scene Documentation and Evidence Collection
- Interviews / Statements involved parties,
witnesses - Clean Up, Vehicle Removal
31Supervisors Role Still In Charge But
- Coordinates Response enhanced team
investigation using other TIU elements. - Resource Allocation
- Organizational Support
- Manages Media at the Scene
- Handles Notifications
- Runs Interference Allows us to do our job
32Supporting Patrol
- 720 squad members are active during rush hour,
special events, bad weather, and other high
traffic periods. - Emphasis on highway incidents.
- Objective is to keep patrol division resources
available for non traffic related calls.
33During Test Period 720 Squad Handled
- 1,945 calls for service
- 50 fatality Crashes
- 318 Injury Crashes
- 235 Non Injury Crashes
- 77 Complete Crash Reconstructions
- 83 Police Vehicular Crashes
- 80 Commercial Vehicle Crashes
34Factors to Consider
- Special Needs
- Timely Notification of Medical Examiner
- Map it now or come back later
- Traffic Control / Incident Signs for highway
scenes, update TOC - Arrange tows or turn scene over to MODOT for
clean up
35Highway IncidentsMapping it now or Later?
- Investigators Safety?
- Time of Day and Traffic Volume?
- Location, Special Events, etc.?
- Sufficient Resources Available?
- How much of the scene will require mapping
personnel to be in the roadway?
36Highway IncidentsMapping it Now or Later?
- Can the scene be shot from another vantage point
using a reflector-less instrument? (overpass,
roadside, ramp, etc.) - Use available technology and resources to your
advantage.
37- The following 2 maps were shot using a
reflector-less total station without having the
road closed or officers in the roadway.
38I-670 and Locust
39Cookingham and I-435 (West)
40Mapping it Now
- Document evidence located in the roadway first,
and work across the roadway so individual lanes
that can be reopened before you measure things
that can be done later such as shoulders,
pavement edges, roadside signs and objects. - Document vehicle locations and positions and tow
them away.
41Turning Scene over to MODOT
- MODOT can provide equipment to clear roadway.
- MODOT can arrange tows with proper resources to
expedite recovery. - MODOT will assume responsibility for scene.
- MODOT can set conditions for tow companies to
handle removal.
42The Results
43KC Scout / MODOT Data
- Kansas City experience on KCMO instrumented
routes. Secondary Accidents reduced by 47
Average Time to Clear Incidents went from 39.1
minutes to 22.3 minutes. Marking a 16.8 minute
reduction in how long cars are in the roadway.
Of course this has a direct reflection on the
secondary routes also. The time to clear a
back-up went from 11.1 minutes to 5.6, a 5.5
minute reduction in the time it takes to clear
the back-up from incidents 122 increase (year
to date) in traffic fatalities 2008
44The Real Difference
- For level 3 incidents (90 minutes and above)
fatalities, huge wrecks, hazardous materiel
etc.....We have shaved 111 minutes off of the
incident duration. Almost 2 hours has been
eliminated due to these incident management
efforts. This is a huge economic, safety and
secondary crash benefit.
45Our Findings
- 90 minute clearance time is not unrealistic.
- Investigations have not been compromised
- Shared responsibilities have actually improved
the quality of our investigations and enhanced
performance of our squad. - Improved relationship with KCFD and others
