1. A method for evaluating data relating to a vehicular accident comprising the steps of:
- capturing a first set of data according to a first recording criteria wherein the first data set comprises operational data for a vehicle including telematics data indicative of vehicle dynamics and contextual data indicative of location and time data;
storing said first set of data in a telematics device;
transmitting said first set of data to a central server;
capturing a second set of data according to a second recording criteria, wherein the second set of data comprises operational data for the vehicle including telematics data indicative of vehicle dynamics and contextual data indicative of location and time data, wherein the second set of data is captured at a higher frequency than the first set of data;
storing said second set of data in the telematics device, wherein the stored set of data is periodically overwritten;
selectively retrieving the second set of data using an accident key in the event of an accident and transferring to the central server;
determining a time of the accident by the central server based at least in part on the second set of data; and
combining at least portions of the first set of data and the second set of data to evaluate conditions relating to the vehicular accident.

10. A system for retrieving and storing data relating to an vehicle accident comprising:
-
a plurality of sensors configured to collect operational data including telematics data indicative of vehicle dynamics and contextual data indicative of location and time; a telematics device having a first memory and a second memory wherein the first memory is configured to store a first set of data collected from the plurality of sensors according to a first criteria and the second memory is configured store to a second set of data collected from the plurality of sensors according to a second criteria, wherein further, the telematics device is configured to transfer the first set of data to a central server; an accident key configured to communicate with the telematics device and extract the second set of data following a vehicle accident and further configured to communicate the second set of data to a central server; and the central server configured to; determine a time of the accident based at least in part on the second set of data; and combine at least portions of the first set of data and the second set of data to evaluate conditions relating to the vehicle accident. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A method for evaluating a vehicle accident comprising the steps of:
-
receiving, via one or more processors, data relating to the operation of a vehicle involved in an accident from a telematics device including location data, operational data, and associated time data for a predetermined time period; comparing, via one or more processors, a horizontal dilution of precision (HDOP) value associated with the location data to an accuracy threshold, wherein the accuracy threshold is less than or about five; filtering data not satisfying the accuracy threshold; and determining the time of the accident based at least in part on the received data. - View Dependent Claims (18, 19)
