Traffic Crash Reconstruction


This course includes extensive project work to give students first hand experience in crash reconstruction. Each student will be required to diagram and analyze several different crash scenarios as well as complete vector sum analysis of each.

Topics include:

  • Derivation and origin of the commonly used speed formulas
  • Behavior of vehicles in a collision using Newton's three laws of motion
  • Discussions of commercial vehicle and motorcycle dynamics in collisions
  • Determination of direction of travel, initial contact and position of vehicles on the roadway

Target Audience

This course is designed for experienced traffic crash investigators with a good working knowledge of the techniques and applications of formulas taught in fundamental/advanced investigation courses. This course will build upon the student’s understanding of vehicle dynamics. It will provide more elaboration into the study of time/distance calculations, two-dimensional momentum and impact speed calculation using momentum equations.
