Method and system for performing crash analysis of one or more vehicles

A computer-implemented system for performing crash analysis of one or more vehicles involved in a crash, the system comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the processor executes a plurality of modules stored in the memory, the plurality of modules comprising:
• a trajectory module configured to
• periodically receive a plurality of GPS samples associated with a vehicle;
• generate a trajectory for the vehicle by tracing the plurality of GPS samples;
• and
• segment the trajectory into one or more macro level segments, wherein each macro level segment is segmented into one or more micro level segments;
• a scoring module configured to
• receive a plurality of acceleration samples for at least one micro level segment of each macro level segment;
• and
• compute:
• at least one micro level segment score corresponding to at least one micro level segment based upon the acceleration samples at three axes and the plurality of GPS samples, and
• at least one macro level segment score corresponding to at least one macro level segment based upon the at least one micro level segment score or a reference speed of the vehicle, wherein the reference speed is indicative of a speed measured corresponding to the at least one macro level segment and a macro level segment adjacent to the at least one macro level segment;
• and
• a crash analysis module configured to
• determine a crash responsibility score based upon the at least one macro level score, the crash responsibility score for performing crash analysis of the vehicle, wherein the crash responsibility score represent responsibility score of each vehicle involved in the crash, and wherein the crash responsibility score comprises a numerical value within a range of 0 to 1, wherein a 0 numerical value indicates no responsibility and a 1 numerical value indicates full responsibility of the vehicle involved in the crash;
• and
• wherein the processor executes the trajectory module to receive the plurality of GPS samples and the plurality acceleration samples from a GPS sensor and a 3-axis accelerometer sensor associated with the vehicle.

A non-transitory computer readable medium embodying a program executable in a computing device for crash analysis of one or more vehicles involved in a crash, the program comprising:

• a program code for periodically receiving a plurality of GPS samples associated with a vehicle;
• a program code generating a trajectory for the vehicle by tracing the plurality of GPS samples;
• a program code for segmenting the trajectory into one or more macro level segments, wherein each macro level segment is segmented into one or more micro level segments;
• a program code for receiving a plurality of acceleration samples for at least one micro level segment of each macro level segment;
• a program code for computing:
• at least one micro level segment score corresponding to at least one micro level segment based upon the acceleration samples at three axes and the plurality of GPS samples, wherein the program further comprises a program code to receive the plurality of GPS samples and the plurality acceleration samples from a GPS sensor and a 3-axis accelerometer sensor associated with the vehicle, and
• at least one macro level segment score corresponding to at least one macro level segment based upon the micro level segment score or a reference speed of the vehicle, wherein the reference speed is indicative of a speed measured corresponding to the at least one macro level segment and a macro level segment adjacent to the at least one macro level segment;
• and
• a program code for determining a crash responsibility score based upon the at least one macro level score, the crash responsibility score for performing crash analysis of the vehicle, wherein the crash responsibility score represent responsibility score of each vehicle involved in the crash, and wherein the crash responsibility score comprises a numerical value within a range of 0 to 1, wherein a 0 numerical value indicates no responsibility and a 1 numerical value indicates full responsibility of the vehicle involved in the crash.
