1. A computer-implemented method comprising:
- receiving black box information obtained from an event data recorder of a first vehicle involved in a collision, at a computer system remote from the first vehicle, the black box information including first information regarding a first collision involving the first vehicle and a second vehicle or other object and second information regarding a second collision involving the first vehicle and a third vehicle or other object;
determining a sequence of events between the first and second collisions in the computer system using the first information and the second information;
reporting the sequence of events from the computer system;
determining in the computer system whether human factors played a role in the first collision, including determining a distance from when brakes of the first vehicle were applied until the first collision occurred using the first information that includes an indication of when the brakes were applied and a velocity of the first vehicle at such time; and
generating a report on the human factors in the computer system based on the determined distance and information obtained independently of the event data recorder regarding a scene of the first collision, wherein the human factors include delayed action.

Abstract
Disclosed are methods and apparatus for using black box data to analyze vehicular accidents. The methods include obtaining information from an event data recorder associated with a vehicle and using the data obtained therefrom in determining and analyzing the vehicular accident. Attributes to be analyzed include impact severity, change in velocity, and other desired parameters. Further disclosed are methods to securely communicate the downloaded black box information to a secure location for later analysis and processing.
