Event Data Recorders - EDR "Black Box" Downloads
Accessing EDR "Black Box" data from each involved vehicle is critical when investigating an accident or performing a comprehensive Accident Reconstruction. These devices are installed on the majority of Commercial and Passenger vehicles produced today and in many vehicles dating back as far as 1994 and can provide pre and post-crash information including speed and deltaV as well as identifying driver actions including throttle, braking and seatbelt usage. EDRs in newer vehicles can provide even more robust datasets including lateral deltaV, tire pressure, cruise control, ABS and Airbag information. When supported by traditional Accident Reconstruction findings, EDR information can help accurately portray the accident sequence, identify causation and provide compelling evidence in a trial or mediation setting.
Most dealerships and repair centers do not have the software, specific training or experience to download all of this critical and at times volatile data, but Bloomberg Consulting maintains all of the latest hardware and software needed to download any available vehicle and our Eperts and CDR Technicians are trained, CERTIFIED and experienced in downloading and analyzing Black Box crash data from passenger vehicles (cars, pickups, SUV's, etc), tractor-trailers, and heavy trucks.
EDR data from most late model heavy trucks, domestic cars and light duty vehicles, as well as cars manufactured by Toyota, Honda, Infinity, Lexus, Scion, Accura, Mazda and Nissan are now available for download. Download the current EDR Availability Guide here to see a complete list of available vehicles.
Toyota, Lexus, Honda, Accura, Mazda, Suzuki, Nissan and Infiniti EDR Downloads Now Available!
Depending on the vehicle, critical information that may be downloaded from passenger vehicle Event Data Recorders includes Vehicle Speed, Delta-V, Brake On/Off, Percent Throttle, Seatbelt Use and Engine Speed. This pre-crash information is generally available for five to eight seconds prior to impact.
Vehicle makes covered by currently available software include the following (click on the desired manufacturer for additional information and a sample report):

Critical information that may be downloaded from commercial vehicle or heavy truck EDRs can be divided into two categories, Critical Event Data and Trip Data.
Critical Event data is generally associated with rapid deceleration or "hard braking" occurances and includes such information as Vehicle Speed, Brake On/Off, Percent Throttle, Engine Speed, Fault Codes (problems with the vehicle) and Cruise Control useage. Some of this information is available for up to two minutes prior to and 15 seconds after the event. Trip data represents cummulitive data captured over time since the last time the system was reset. Relevant information may include Number of "Hard Brakes", High Speed, % Drive Time Over Speed, % Drive Time Using Cruise Control and engine settings like Maximum Governed Speed.
The data that is available from heavy trucks and tractor-trailers is dependent on the type and manufacturer of the engine, rather than the manufacturer of the truck itself. The engines that currently provide this "Black Box" data include the majority of engines that are on the road in the Unites States today, such as:
AFTERMARKET TRACKING SYSTEMS
In addition to the information from factory-installed EDR's, there may be information available from aftermarket tracking systems installed on many vehicles today. GPS navigation units in cars and trucks, for example, have memory cards that contain trip information, often including speed and GPS co-ordinates recorded at regular intervals. On heavy trucks, electronic vehicle locators and automatic driver logbook systems, known as Electronic On-Board Recorders or Telematics, are becoming commonplace. Besides being confirmation of a driver's duty status and hours, these systems may offer accident reporting or hard brake and other critical incident records.
Bloomberg Consulting is familiar with the data collected by aftermarket vehicle tracking systems and has developed techniques for incorporating this data into our accident analysis and reconstruction. Telematics systems from companies such as Qualcomm, Discrete Wireless, Cadec, Xata, and PeopleNet may provide GPS-based data to confirm travel speeds and driver hours of service. Radar-based systems such as VORAD can add information about both the radar-equipped vehicle and the other vehicles around it at the time of the incident. Our experienced engineers will alert you to the presence of these systems and ensure that the data is collected, preserved and incorporated into the accident analysis.
