Upcoming Courses
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.

Crash Investigation 2 On-Ground
Tuition: $1200 | Prerequisites: Crash Investigation 1 (On-Ground or Online)
Crash Investigation 2 builds upon the foundational topics examined in Crash 1. Students acquire the technical skills needed to properly utilize specialized data gathering methods to collect and prepare on-road crash investigation data, perform an initial interpretation of available data, and obtain critical follow-up information. 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.

Vehicle Dynamics On-Ground
Tuition: $900 | Prerequisites: Crash Investigation 1 (On-Ground or Online), Crash Investigation 2 (On-Ground or Online). Completion of high school-level physics, algebra, geometry, and trigonometry is highly recommended.
Provides students with the basic math and laws of physics required for Traffic Crash Reconstruction 1 and 2. The course covers the motion of bodies and the action of forces in producing or changing that motion (dynamics) as related to traffic crashes. Students learn the classical mechanics equations of motion, drag factor, and friction and acceleration coefficients. Vehicle Dynamics also introduces the methodology used to estimate vehicle speeds based on flips, vaults, and sideslip and teaches the differences between force, momentum, and energy as applied to crash investigation and reconstruction.

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
Completely revised and updated! Traffic Crash Reconstruction 1 (TCR1) features a new 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 new, 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).
