Scenario reconstructionists and forensic analyzers conduct thorough analyses of collision and then reconstruct the scenario to determine the grounds of collision and the factors that contributed in the incident, including the roles of the drivers and their vehicles involved, the roadway drove, and the environment surrounding the crash scene.

Laws and principles working behind the physics and engineering, such as linear momentum, employment, energy and kinematics is the rear base of this analysis and can utilize computer software to calculate the useful data and figures. 

With the use of powerful but inexpensive and specialized software, such as best photogrammetry software experts can do crime scene reconstructions easily. Photogrammetry program is a typical example of the computer software used by accident reconstructionists.

Accident reconstruction provides a comprehensive analysis of professional witnesses can be present in court. Car accident reconstruction is done in cases where deaths and injuries involved. 

Data were collected from accident reconstruction that has proven useful in redesigning and developing new and safer roads and highways, as well as improving vehicle design and safety mechanisms. 

Forensic professionals, special law enforcement units or private consultants do the reconstruction. Accident scene and investigation visits all involved in the inspection vehicle collision scenarios and data retrieval. Collection of evidence such as scenes photos and videos, physical measurements, the testimony of witnesses and legal depositions are several basic methods to do the investigation. 

Car accident reconstruction analysis involves the collection and processing of data, evaluation of the probability and the possible hypotheses, scenarios recreation model creation and simulation software. 

After a series of analysis is complete, forensic engineers prepare police reports, diagrams and computer-generated animation to build expert testimony and conclusions about the accident.
