NUCPS Crash Investigation & Reconstruction
The concept of scientific crash investigation has been a part of the Northwestern University Center for Public Safety since its inception in 1936. We literally "wrote the book" on crash investigation and reconstruction, and we continue to be world leaders in providing training in these areas. Our Crash Investigation program is the most comprehensive program of its kind, with courses beginning at basic crash investigation and culminating in various advanced crash reconstruction courses.
Traffic Crash Investigation Courses
Crash Investigation 1
"Will make you think about crashes in a whole new way. . . Extremely informative and has good hands-on application. Once you finish with this course, you feel empowered to handle traffic crashes." - Sgt. Wayne Jakobitz, Bourbonnais (IL) Police Department
Crash Investigation 1 introduces the concept of traffic crash investigation. Based on J. Stannard Baker's renowned text, Traffic Crash Investigation, 2014 Edition, Crash 1 offers an in-depth study of the skills needed to investigate a traffic collision scene, thoroughly covering the techniques for recognizing and properly recording roadway and vehicle crash evidence. Students learn to measure and photograph accident scenes and to create sketches and after-crash diagrams. Crash 1 also addresses how collected data are used to reconstruct traffic accidents, as well as the use of electronic devices for collecting and recording at-scene data.
Upcoming Crash Investigation 1 Classes
Crash Investigation 2
Crash Investigation 2 emphasizes vehicle behavior in crashes, vehicle damage analysis, and advanced mapping and evidence location skills. Crash 2 builds upon topics examined in Crash Investigation 1 and provides students with greater knowledge of the information available at an accident scene and of the proper techniques for collecting and initiating interpretation of that information. Crash Investigation 2 also covers the use of laser-based measurement devices and downloading electronic information into mapping programs.
Upcoming Crash 2 Courses
Vehicle Dynamics introduces the laws of physics and mechanics that relate to traffic crashes and prepares students for NUCPS crash reconstruction courses.

Traffic Crash Reconstruction Courses
Traffic Crash Reconstruction 1 (73 ACTAR CEUs)
"Reconstruction 1 is a challenging course, but the manner in which it is presented keeps you interested . . . The instructors are top notch, and the case studies are unique. The case studies push you to think logically and apply the newly learned information to help make sense of how the crash occurred. Man, is it satisfying when you are on the right track!" - Officer WE Kumpula, Antioch (IL) Police Department on the new Traffic Crash Reconstruction 1
Completely revised! Our renowned reconstruction course features a new format that focuses on the basics of traffic crash reconstruction. Students are immersed in such critical core material as: engineering mechanics; vehicle behavior in collisions; an introduction to human factors; time-distance analysis; EDR usage in traffic crash reconstruction; post-collision drag factor analysis; momentum; and, special velocity calculations (e.g., sideslip, falls, vaults, and flips).
Upcoming Crash Reconstruction 1 Classes
Last Chance! Traffic Crash Reconstruction 2 - Old Format
Any student who completed Traffic Crash Reconstruction 1 before October 2019 but has yet to take Traffic Crash Reconstruction 2 no longer meets the prerequisites for the the revised Traffic Crash Reconstruction. For students in this situation, NUCPS has opened one final section of Traffic Reconstruction 2 - 2010 (the "old format"). Take advantage of this Feb. 17 - 21, 2020, course!
Traffic Crash Reconstruction 2 (35 ACTAR CEUs)
Completely Revised! Building upon the basics taught in the new format of Traffic Crash Reconstruction 1, the newly revised Traffic Crash Reconstruction 2 focuses primarily on energy-based analysis. During this course, students learn the principles of energy and damage energy, occupant behavior, and momentum and energy analysis, and also receive an introduction to force balance.
Upcoming Crash Reconstruction 2 Courses
Traffic Crash Reconstruction 3 (40 ACTAR CEUs)
Traffic Crash Reconstruction 3 provides the reconstruction professional with advanced analytical and methodological concepts to better understand and explain real-world crash reconstructions. In-depth instruction is focused on Monte Carlo analysis, advanced concepts in energy and advanced concepts in momentum.
Upcoming Crash Reconstruction 3 Courses
Traffic Crash Reconstruction Refresher (23 ACTAR CEUs)
This refresher is for those who completed their crash reconstruction training some time ago and need to renew their skills or for those who need an update on newer technologies, such as EDR, LED or HID vehicle lights, ABS brakes, or stability control. The course reviews the basic physics techniques that are used to analyze traffic crashes as well as the newest technologies in the field.

Upcoming ACTAR Exam Dates
NUCPS strongly encourages all crash reconstruction students to pursue ACTAR accreditation. The final step in the process is the accreditation examination. The exam is offered several times per year in the US and around the world.
Upcoming US test dates and locations include:
- Dec. 14, 2019: Millersville, MD
- Dec. 16, 2019: Lake Zurich, IL
- Jun. 14, 2020: Altoona, IA

This course examines the unique characteristics of how heavy vehicles, especially articulated vehicles, perform in various crash scenarios. Areas of emphasis include assessment of truck braking systems, EDRs, tachygraphs, and gear positions. Includes seven ours of field testing and the opportunity to analyze and apply collected data.
Upcoming Heavy Vehicle Reconstruction Courses
Motorcycle Crash Reconstruction (39 ACTAR CEUs)
This course examines the unique and specialized characteristics of motorcycles when involved in collisions or loss of control incidents. Topics covered include vehicle components, vehicle handling, unique dynamics, event data recorders and the braking system, and the course includes practical outdoor exercises using actual motorcycles.

Pedestrian/Bicycle Vehicle Crash Reconstruction (40 ACTAR CEUs)
Crash reconstructionists understand that when a vehicle strikes the human body, the body will behave differently than another vehicle would in the same situation. Vehicle versus pedestrian/bicycle collisions often result in traumatic injuries or fatalities on the part of the pedestrian or bicyclist. Accuracy is especially important when investigating and reconstructing crashes involving these types of crashes. In Pedestrian/Bicycle Crash Reconstruction, students learn the mathematical equations to model such collisions and the appropriate formulas for varying crash scenarios.
