Claim Text:
1. A computer-implemented method for determining vehicle speed during periods of intermittent GPS, the method comprising: receiving, via a computer network, one or more of GPS data or accelerometer data corresponding to a driving session of a vehicle; if GPS data is received, determining, by one or more processors, if the GPS data is available or accurate for the entire driving session; determining, by one or more processors, one or more time periods during the driving session when the GPS data is not available or accurate; for each of the one or more time periods when the GPS data is determined to be unavailable or inaccurate, analyzing, by one or more processors, the accelerometer data received during that period to determine idling points when the vehicle is not moving; dividing, by one or more processors, each of the one or more time periods into two or more segments based on the determined idling points for each time period; for each of the two or more segments in each of the one or more time periods: determining, by one or more processors, a driving behavior based on at least the calculated speed of the vehicle at the points when the vehicle is moving in each of the two or more segments in each of the one or more time periods when the GPS data is not available or accurate.
