Accident reconstruction requires a thorough analysis of the available evidence, data and witness statements. Michigan Accident Reconstruction has advanced technologies, vast training and experience to reconstruct all types of traffic accidents including motorcycles, passenger cars, light trucks, bicyclists, pedestrians and commercial vehicles. The findings of these complex issues are communicated in clear, comprehensive and timely reports. Michael David has been qualified as an expert witness on multiple occasions. He clearly communicates and explains complicated technical issues that are involved in accident reconstructions.

Most vehicles involved in crashes today are equipped with event data recorders (EDR), commonly known as black boxes, which capture critical data associated with the collision event. Michigan Accident Reconstruction has extensive experience, along with the necessary equipment and software, to obtain and analyze this data.

EDR data provides valuable insights into how a crash occurred, including vehicle speeds leading up to the collision, steering and braking inputs, and driver actions before impact. Some vehicles also capture still images or even video footage. As EDR technology advances, the amount of recorded data continues to grow, making its retrieval and analysis increasingly valuable for accident investigations.

Some of the technologies we have are:

• Bosch Crash Data Retrieval equipment and software
• Tesla equipment
• Hyundai GIT equipment and software
• Kia GIT equipment and software
• Toyota Vehicle Control History (Techstream)

With the proliferation of cameras, traffic accidents are being recorded more frequently than ever. Surveillance cameras, dashcams in police, commercial, and private vehicles, police body cameras, and mobile phone cameras all can provide valuable footage for crash analysis. When properly analyzed using specialized software, these recordings can offer critical insights, including speed determinations for vehicles and pedestrians, helping to reconstruct the sequence of events and determine contributing factors.

Vehicle inspections are an important component of accident reconstruction. By thoroughly examining the vehicle and documenting the findings – through photography, measurements, and laser 3D scanning, reconstructionists can gain insight into the crash dynamics. The patterns of interior damage help to assess occupant movement during the crash and precrash seating positions. This inspection can also confirm seatbelt usage. In certain cases, inspecting the vehicle’s exterior lamps can provide information on whether the lights were on or off at the time of the accident.

Forensic mapping is a precise method used to document crash scenes in both 2D and 3D. Utilizing drones, survey instruments, and laser scanners, investigators capture detailed data, which is then processed through specialized software such as Pix4D and Virtual Crash to create a 3D environment. This digital reconstruction enables in-depth analysis of key factors, including time-distance relationships, visibility issues, crash dynamics, and potential collision avoidance scenarios. Additionally, simulations and animations can be generated to visually depict the sequence of events, providing valuable insights.

Crash scene investigations are useful in reconstructing traffic accidents by uncovering physical evidence that may otherwise go unnoticed. Physical evidence, such as gouge and tire marks, provide valuable insights into the dynamics of a collision. Additionally, factors like lighting, roadway design and condition, traffic patterns, signage, and traffic signal operations can be examined in detail to assess their influence on the crash.

The area of impact is often identifiable through careful analysis. Potential visibility issues that may have contributed to the incident may also be identified. Advanced documentation methods, including 3D modeling with drones, survey instruments, laser scanners and specialized software, enable scene reconstruction to scale. This data can serve as a valuable resource to later analyze the crash further.
