1. A method to synchronize vehicle operation information of a vehicle, the method comprising:

  • receiving the vehicle operation information, wherein the vehicle operation information is based on output signals generated by a plurality of sensors, wherein the plurality of sensors includes a first sensor that generates a first output signal conveying a first operating parameter of the vehicle and a second sensor that generates a second output signal conveying a second operating parameter of the vehicle, wherein the first output signal is associated with first timing information, wherein the second output signal is associated with second timing information, and wherein the first output signal and the second output signal include information that indicates an occurrence of a vehicle event, the vehicle event having a start time and an end time;

    associating information from the first output signal and the second output signal generated during the vehicle event to create an event record, wherein the first timing information includes a first time-stamp that indicates the start time of the vehicle event, wherein the second timing information includes a second time-stamp that indicates the start time of the vehicle event, and wherein the first time-stamp does not coincide with the second time-stamp;

    synchronizing the information from the first output signal and the second output signal generated during the vehicle event based on analysis of the first time-stamp and the second time-stamp, wherein synchronizing includes identifying and correlating corresponding information associated with one or more physical phenomena in the first output signal and the second output signal during the vehicle event; and

    causing a graphical user interface to present the synchronized vehicle operation information to a user.
