Methods and systems are provided for correlating mobile platform data with secondary device data. In an exemplary embodiment, mobile platform data and secondary device data are obtained. The mobile platform data pertains to a mobile platform. The secondary device data originates from a secondary device that is movably disposed within the mobile platform at certain times. The obtaining of the secondary device data is independent from the obtaining of the mobile platform data. The mobile platform data is correlated with the secondary device data, via a processor.

Vehicle and device trip correlation

A method implemented in a smartphone associated with a transportation apparatus to detect a crash of the transportation apparatus, comprises receiving a signal generated in time domain by a sensor of the smartphone in response to an event triggered by motion of the smartphone. The method further comprises transforming the signal to a delay domain to generate a two-dimensional representation of the signal in the delay domain. The method further comprises processing the two-dimensional representation using a Hough transform to select lines from the two-dimensional representation having a parameter greater than or equal to a predetermined threshold. The method further comprises determining a pattern associated with the selected lines, comparing the pattern to a predetermined pattern indicating crash event of the transportation apparatus, and determining based on the comparison whether the event indicates crash event of the transportation apparatus.
