Advanced Collision Reconstruction with CDR Applications

Instructor: Greg Russell

This class will teach participants how to use CDR data in their collision reconstructions, using real-world crash examples.

This class is not a replacement for a CDR Analyst class, but acts as a supplement to it, taking the analysis of the data a step further.

NAPARS members price: $395.00

Non-members price: $595.00

This class has been approved for 40 ACTAR CEUs

Topics Include:

  • Pre crash data sources 
  • Crash pulse data
  • Calculating Δv from acceleration data
  • Calculating Δvtotal and PDOF from Δvx  & Δvy 
  • Adjusting Δvx to find total Δvtotal 

  • 360˚ Conservation of Linear Momentum with a single equation
  • Calculating Impact & Post Impact Velocities from CDR data
  • Reconciling Pre-Crash and Post-Crash CDR data
  • Analyzing CDR data in Context of your Reconstruction
  • This class will review pre-crash and delta-v data from currently supported vehicles and may include additional updated CDR info as time allows.

All of the projects presented are based on actual collisions using downloads from those collisions, showing how the techniques taught here can be applied to the real world.
