1. NHTSA's Crash Investigation Sampling System
December, 2016

2. Background
NHTSA’s investigation-based programs take detailed measurements of crash scenes and vehicles
NASS-CDS
CIREN
Special Crash Investigations
Special Studies
Discuss points we measure in scene and vehicle

3. Background
Previously used the same techniques for obtaining measurements as in 1979 when NASS began
Rolling measurement wheels for scenes
Tape measures and contour rods for vehicles

4. Overview of CISS Crash investigation Sampling System (CISS)
Replacement to NASS CDS
– 24 PSU operational in 2017
PSU consists of 2-3 Crash Technicians
Crash Technicians (CT) collect field data
Must complete NHTSA CT training
Labor is #1 cost
Scene savings alone pays for unit in one-year, 10K
End Users want speeds and more detailed scene measurements (think crash avoidance)

5. Overview of CISS Field offices are managed by contractor “A”
Quality control center is managed by contractor “B”
Protocols, Procedures and guidelines are applicable for all 24 sites
Coding and Editing Manual (available on-line)
Technical operational documents (Total Station, EDR, etc.)
Modernization of NASS
CISS 24 sites operational in 2017
Modernized Sample design
Modernized IT system
Labor is #1 cost
Scene savings alone pays for unit in one-year, 10K
End Users want speeds and more detailed scene measurements (think crash avoidance)

6. July 2015: Pilot Crash Investigation Sampling System in 5 data collection sites
January 2016: Begin CISS collection in 12 sites
January 2016: Crash Report Sampling System begins
January 2017: Begin CISS collection in 24 sites
2017 and beyond: Continue to add up to 73 CISS sites

7. Overview of CISS Upgraded data collection tools
Total Station Electronic Measurement Device
Used for Scenes and Vehicles
Labor is #1 cost
Scene savings alone pays for unit in one-year, 10K
End Users want speeds and more detailed scene measurements (think crash avoidance)

8. Overview of CISS Scenes More precise measurements
Safety of Crash Technician
Labor is #1 cost
Scene savings alone pays for unit in one-year, 10K
End Users want speeds and more detailed scene measurements (think crash avoidance)

9. Small sites that target late model year vehicles and injury crashes
24 Sites in 18 States
Small sites that target late model year vehicles and injury crashes
182 Police Jurisdictions
4,000 to 4,500 annual cases
July 2015: Pilot Crash Investigation Sampling System in 5 data collection sites
January 2016: Begin CISS collection in 12 sites
January 2016: Crash Report Sampling System begins
January 2017: Begin CISS collection in 24 sites
2017 and beyond: Continue to add up to 73 CISS sites

10. EDR Bosch CDR Tool Covers “most” vehicles on the road
Other tools available… costs are an issue
EDR kits for all Technicians
Vast expansion of vehicles with EDR support
Better / more data

11. Scene Image and 3D (Lookback)

12. Vehicle damage can also be measured electronically
Produces barrier equivalent speed, similar to WinSmash

13. We’re still evaluating accuracy of vehicle damage modeling
This portion of software, just released.
Scene diagramming software is currently ahead of vehicle damage portion of software
