Reconstitution d’un accident

Les ingénieurs, les spécialistes de la reconstruction et les scientifiques de l’équipe Rimkus offrent une richesse de connaissances et d’expérience dans tous les aspects de l’analyse de la reconstitution d’accidents afin d’évaluer avec précision les preuves cruciales et de reconstituer les accidents complexes. Les experts de Rimkus peuvent évaluer les complexités supplémentaires des accidents de véhicules commerciaux.

Réponse rapide

Une intervention immédiate sur les lieux de l’accident est essentielle à la reconstitution d’un accident de voiture. Nous documentons les conditions du site, y compris les marques de dérapage, l’impact, les derniers lieux de repos, la ligne de vue, les conditions routières, les contrôles de la circulation et d’autres données pertinentes. Il est important d’inspecter les véhicules avant qu’ils ne soient vendus ou détruits. En plus de documenter l’état physique du véhicule, nous pouvons télécharger des données électroniques qui peuvent être enregistrées lors d’un accident ou d’un quasi-accident.

Méthodes de reconstruction et d’évaluation

À l’aide de méthodologies scientifiquement fondées, notre personnel analyse les preuves et détermine les interactions entre les personnes (conducteurs, piétons et témoins), les véhicules et la chaussée et l’environnement. En fonction des preuves disponibles, nous pouvons déterminer les directions et les vitesses des véhicules, les actions du conducteur, le timing des feux de circulation, la visibilité des véhicules ou des piétons, etc.

Expérience de reconstitution d’accident de véhicule :

• Accidents impliquant un ou plusieurs véhicules
• Collisions de véhicules utilitaires
• Collisions mortelles à grande vitesse
• Accidents entre piétons et véhicules
• Accidents de moto
• Accidents de vélo
• Évaluations de véhicules Phantom
• Accidents de renversement de véhicules
• Accidents nocturnes

Rimkus incorporates state-of-the-art technology in data collection and accident reconstruction analysis to further enhance the reliability of field investigations and ensure the accuracy of our findings.

FARO FOCUS 3D™ laser scanners provide Rimkus with a reliable method for obtaining 3D color point clouds and 3D measurements to document accident scenes, vehicles, roadways, and evidence. The scanner produces dense point clouds used in the analysis to determine the cause of complex accidents.

ELECTRONIC DATA can be obtained from vehicles, cell phones, and surveillance systems. Event Data Recorders (EDR) in passenger and commercial vehicles afford Rimkus the opportunity to download vital data from vehicles including speeds, brake use, accelerator use, steering input, seatbelt use, and other data. The infotainment system in many vehicles records user and vehicle data.

That data can include GPS routes/locations, vehicle events, connected devices, call and text logs, etc. Mobile devices (cell phones and tablets) record data including location (GPS), movement, call and text logs, etc. The proliferation of surveillance cameras has resulted in more accidents being caught on camera. Analysis of electronic data can help answer numerous accident reconstruction and vehicle theft questions.

DRONES allow Rimkus to take aerial photographs of accident sites. Drone photographs are used to create 3D point clouds and scaled aerial images of accident scenes used in the analysis to determine the cause of complex accidents.

TOTAL STATIONS allow Rimkus to digitally map accident sites when a 3D scanner or drone cannot be used. The total station data is downloaded into a computer to render the accident scene with pinpoint accuracy.

CRUSH ANALYSIS and CRASH SIMULATION programs allow Rimkus to analyze information such as vehicle crush damage, steering, braking, skid marks, roll resistance, vehicle speeds, and roadway conditions. Based on analyses, Rimkus can determine the pre-impact, impact, and post-impact speeds of the vehicles involved in the accident. An accident can be simulated in 3D, including rollovers.

VEHICLE MAPPING is a reconstruction tool for determining the crush profile of a vehicle. Our reconstruction experts use multiple methods to map vehicle damage including 3D scanners, photogrammetry, iPhone Lidar, and total stations. With a proper crush profile, Rimkus can better analyze the vehicle crush depth and calculate the change in speed and impact configuration of the vehicles at the time of impact.

Our biomechanical engineers can help determine the cause of the injuries claimed or determine if there are inconsistencies between the accident or incident and the injuries being claimed.

Our experts also investigate the function of vehicle occupant protection systems, such as seatbelts, airbags, pretensioners, and child safety seats, to understand their role in mitigating injuries in accidents or incidents. We can help identify whether these systems were being used appropriately and if the lack of appropriate use could have contributed to the injuries sustained by the occupants of the vehicle.

Rimkus biomechanical experts and biomedical engineers offer expertise in physics, accident reconstruction dynamics, biomechanics, anatomy, physiology, and human kinematics.

Using advancements in biomechanics research, our team can determine the causes of bodily injury and if the reported injuries are consistent with the forces experienced in an event. In cases involving disputes over who was driving, our experts can determine the driver of the vehicle, positions of the occupants, vehicle occupant seat belt use, and the type/extent of expected injuries associated with proper seat belt usage.

We perform evaluations that range from low to high-speed collisions to help our clients understand the facts about reported injuries and explain the mechanisms that caused them.

In a perfect world, equipment and vehicles would be properly designed, manufactured, maintained, and unaltered by wear and tear. In the real world, however, this is not the case.

Offering a keen understanding of forensic sciences and failure analysis, Rimkus has organized a specialized group of qualified engineers, ASE mechanics, and materials experts to conduct product evaluations, testing, and analysis of vehicle failures.

Our staff carefully analyzes the subtle relationship between design and use and participates in laboratory analysis of vehicles and subsystems to determine if a failure caused or contributed to property damage or bodily injury.

Conception des routes

The design of the roadway environment is concerned with the positioning of the physical elements of the roadway according to standards and constraints. The experts at Rimkus apply governing standards to analyze sight distances, roadway geometry, roadway pavements, and roadside hazards and can determine if the physical elements of the roadway and roadside environment were implemented appropriately and if they caused or contributed to a vehicle accident.

Work Zone Traffic Control

The function of work zone traffic control is to provide for the reasonably safe and effective movement of road users through a work zone while reasonably protecting road users and workers. The experts at Rimkus can evaluate the construction activity, determine what work zone traffic control was required for the subject activity, and assess if the appropriate traffic control was implemented.

Traffic Signal Operations

Traffic signals assign the right-of-way to the various traffic movements and thereby influence traffic flow on the roadway network. The experts at Rimkus specialize in the design, programming, and analysis of traffic signal timing, intersection layout, signal phasing, and signal maintenance along with witness accounts and accident reconstruction to determine the signal patterns preceding an accident.

Traffic Control Devices

Traffic control devices notify road users of regulations and provide warnings and guidance needed for the uniform and efficient operation of the traffic stream in a manner intended to minimize the occurrences of crashes. The experts at Rimkus can evaluate if the design and placement of a traffic control device was appropriate or if a certain condition required the installation of a traffic control device that was not installed.

DOT Compliance

Rimkus offers complete analysis of all facets of DOT safety compliance including hours of service, driver qualification files, maintenance, regulatory compliance, and industry practices.

A visual representation of an accident or incident event conveys information far better than words alone.
