Claim:
1. A method for determining information relating to the operation of a traffic control signal, the method comprising: using live vehicle probe data comprising positional data relating to the movement of one or more devices with respect to time in a recent time period along a path controlled by the traffic control signal to determine transition time data indicative of one or more times at which a transition between phases of the traffic control signal occurred, wherein the recent time period is within a specified amount of time of a present time; using historical positional data relating to the movement of one or more devices with respect to time along the path controlled by the traffic control signal and aggregated over a plurality of occurrences of a given time period to determine cycle time data indicative of a cycle time of the traffic control signal, the given time period including the one or more times at which transitions between phases of the traffic control signal occurred; and using the transition time data and the cycle time data to predict one or more times at which a future transition between phases of the traffic control signal is expected to occur.
