IPTM’s Advanced Traffic Crash Analysis, Second Edition, is an expanded and updated version of its predecessor, our popular Advanced Traffic Crash Analysis manual. In addition to four new chapters, updated photos and charts, and nearly 100 more pages, there is a 500± word Glossary—one of the most comprehensive in any text or reference manual on the topic of crash reconstruction. Using straightforward easy-to-understand language, the authors provide easy-to-follow guidance for those tasked with the complex job of investigating traffic crashes. The manual was created to bridge the gap between At-Scene Traffic Crash Investigation and Traffic Crash Reconstruction while following the learning objectives of IPTM’s Advanced Traffic Crash Investigation course. This new edition will serve as a comprehensive text and reference work for anyone with an interest in the crash investigation field. Updated in 2017, Advanced Traffic Crash Analysis presents all equations, examples, and calculations in both the US system of measurement and the Système International (SI), previously known as the metric system, making it equally useful internationally.
