1. A system, comprising:
a communication network;
a telematics monitor; and
a collision detection facility in communication with the telematics monitor over the communication network;
wherein the system is configured to:
capture, by the telematics monitor coupled to a vehicle, high-rate acceleration data, speed data, and global positioning system (GPS) data;
receive, at the collision detection facility, the high-rate acceleration data, speed data, and GPS data from the telematics monitor;
compute, by the collision detection facility, each of:
an acceleration context based on the high-rate acceleration data;
a pullover context based on the speed data;
a speed context based on the speed data; and
a road context based on the GPS data;
compute, by the collision detection facility, an accident score based on the acceleration context, the pullover context, the speed context, and the road context; and
in response to determining that the accident score indicates a potential collision, the collision detection facility sends a message to the telematics monitor for triggering at least one action for responding to the potential collision.
