Crash Investigations - Anytime, Anywhere:

"A process of systematic collection and analysis of information relating to a road traffic crash, to identify the causal and contributing factors (human/vehicle/infrastructure) influencing the crash and the resulting injuries."

JPRI researchers are experts in crash investigations. Our well-defined methodologies and detailed examinations of crash scenes and vehicles, coupled with effective driver/victim interviewing techniques, and a good understanding of injury mechanisms, can help anyone wanting to understand how the crash or the subsequent injury would have occurred. Our professional crash reconstructions and simulations provide a visual and compelling understanding of any crash.

Crash Reconstructions:

"A systematic process of evaluating the evidence associated with a particular collision sequence and applying accepted physical principles in order to ascertain how the collision occurred."

Apart from how crashes and injuries occur, questions such as “what was the travel speed?”, “what was the speed at the time of impact?”, “is it possible for a vehicle to move like that?”, “how could this accident have been avoided?”, etc. also need answers. This is provided by our team of crash reconstruction experts who apply physics and mechanics to a crash and with the help of accident reconstruction software determine these answers.

Injury Analysis:

"A systematic process involving the extraction of injuries sustained by a crash victim, determination of injury severity of each injury (using injury scaling techniques) and correlation with the injury sources in a crash (e.g. vehicle components such as windshield, a-pillar, bull bars, etc. or road objects such as trees, guardrails, walls, concrete structures, etc.) through a good understanding of occupant/pedestrian kinematics, human injury tolerances and injury mechanisms."

Not all the injuries of a crash victim lead to a fatality or disability, but examining each of them individually helps in understanding them better. At JPRI, we have adopted well-established injury scaling practices [Abbreviated Injury Scale (AIS)] that are utilized by certified injury research experts in determining the severity of every single injury. Trained by world-renowned bio-mechanists, our injury research experts excel in examining injuries and their severity, visualising the motion of the human body during a crash (kinematics), and determining the sources of these injuries in a crash scene or vehicle .

Traffic and Crash Data Collection Methodologies and Analysis:

" Without data, you are just another person with an opinion”. W. Edwards Deming

Availability of scientifically collected data promotes evidence-based decision making. In the transport industry, this not only means saving lives and mitigating injuries, but also improving cost-efficiency and effectiveness. JPRI researchers are trained and experienced with handling traffic/crash data collection, identifying various sources, analysing the data thoroughly and determining meaningful insights that will make the data work for you.


" If we can do it, so can you!”

Crash investigations, reconstructions, injury analysis, data collection, etc. is a science, but not a rocket science that is difficult to understand. Engineers, physics and biology graduates, law enforcement officers, and even high school graduates, with sufficient efforts and learning can gain these skills. JPRI strongly feels that crash investigation is a skill that needs to be learnt and practiced across the country, if India wants to reduce the fatality rate on our roads.
