Abstract

The development of Event Data Recorder (EDR) devices in both passenger and heavy/commercial vehicles is continuously evolving, with newer models containing more and more information. With this ever-changing technology those involved in the study of collisions need to stay well-informed of the electronic data available from vehicles involved in collisions as the data can be used to provide a better understanding of the circumstances in which crashes and injuries occur. The aim of this study was to provide a state-of-the-art review of the latest technologies and data available in current passenger and commercial vehicles. For passenger vehicles, manufacturers are required to include EDRs to meet safety standards in the countries in which they are sold, with increasing requirements for the number and type of data elements recorded. Modern commercial vehicles are equipped with an increasing array of EDR technologies such as telematics, collision mitigation systems, and video coaching systems in addition to the more traditional engine-based electronic data, all of which can be used for collision investigation and reconstruction. By providing a state-of-the-art review of the latest EDR technologies, those involved in the study of collisions will be made aware of the data available from crash reconstruction. This data can then be used to provide a better understanding of the circumstances in which collisions and injuries occur, ideally leading to safer roadway and vehicle designs. The key deliverables included a summary description of the technology and data elements available in current passenger and commercial vehicles. The target group for the state-of-the-art review are those involved in the study of collisions, who want a better understanding of the electronic data and tools available to help them understand the dynamics of a collision. By understanding the type of data elements recorded by the collision vehicles, the target group will be equipped to plan future studies on new vehicle technology or aspects of roadway design. The state-of-the-art review of EDR technologies was conducted by reviewing product and scientific literature. Developers and manufacturers were contacted for technical details and data information. Product details were compiled and a summary description of each technology was made. As far as possible, we have tried to be comprehensive and representative in the listing of the technologies and products. The output of this work included a summary of the state-of-the-art EDR technologies. The technologies were divided into two major categories: passenger vehicles and commercial vehicles. Subcategories for passenger vehicles included the type and format of data elements available. Subcategories for commercial vehicles included engine-based electronic data, telematics, collision mitigation systems, and video coaching systems. The information will be applied by proposing the type of data elements that are available for future studies regarding vehicle safety and roadway design.
