The class will further enable participants to proficiently investigate traffic crashes. Building upon what was learned in At-Scene Traffic Crash Investigation, investigators will enhance their abilities to perform lamp examinations, draw scale diagrams, and perform time-distance, momentum, falls, flips, and vault calculations. Participants should bring all traffic crash investigation equipment to class with them, including 100'/300' tapes, hammer/masonry nails, compass, line/line level, scientific calculator with trigonometry functions, a digital camera (if possible), and safety equipment. There will be a final written examination and participants will be graded on practical exercises. A minimum accumulated grade is required to successfully complete the course. Prerequisite: At-Scene Traffic Crash Investigation (80-hours). Required text: IPTMs Advanced Traffic Crash Analysis (ISBN 1-884566-64-2). This class is taught by seasoned reconstructionists who are also experienced instructors. Topics include: Speed estimates from kinetic energy, skid marks, scuff marks, yaws, and airborne situations. Vehicle dynamics and motion. Time, distance, and motion equations. Conservation of momentum equations. Center of mass calculation. Vehicle damage analysis including thrust, overlap and collapse. Vehicle lamp examination. Tire damage evaluation. Scale diagrams. Vector sum analysis.
