Traffic Crash Investigation and Safety Engineering

The concept of scientific crash investigation has been a part of the Northwestern University Center for Public Safety since its inception in 1936. Our Traffic Crash Investigation and Safety Engineering offers comprehensive courses, from introductory crash investigation through advanced crash reconstruction and engineering courses. 

Most of our available courses are offered in on-ground or online formats.

Crash Investigation 1 On-Ground

Prerequisites: None.  Tuition:  $1200

Crash Investigation 1 is the foundation class for NUCPS’ internationally respected traffic crash and reconstruction courses. 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, as well as information from involved parties and witnesses. 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 and introduces the use of electronic devices for collecting and recording at-scene data.

Upon successful completion of Crash 2, students will understand how the latest generation of vehicle electronics (e.g., EDRs, traction and stability controls) affect a crash and its subsequent investigation.

This course emphasizes vehicle behavior in crashes, vehicle damage analysis, the application of a systematic procedure for alter use in reconstruction effort, the use of laser-based measuring devices and mapping software, and advanced evidence-location skills. Instructors also discuss hit-and-run investigations, emerging technologies and technical report writing.

Upcoming Crash Reconstruction Courses

Traffic Crash Reconstruction 1 On-Ground

Tuition: $1250  |  Prerequisites:  Online or On-Ground: Crash Investigation 1, Crash Investigation 2, and Vehicle Dynamics; or, equivalent crash investigation courses and with NUCPS department approval.
Professional Credits: 80 ACTAR CEUs

Traffic Crash Reconstruction 1 (TCR1) features a format that focuses on analyzing and interpreting information that has been collected during the initial crash investigation to describe the events leading to actual impact and the crash itself in as much detail as possible. Students learn how to apply skills obtained through course lectures to real-world case study situations and complete the class with the training necessary to reconstruct traffic collisions. TCR1 covers 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).
