METHODS OF OBTAINING AND USING POINT OF INTEREST DATA

Data identifying a geographic location of a dynamic POI is obtained. A database storing data indicative of a plurality of duration time functions is accessed, each duration time function being associated with data indicative of a geographic location, and each duration time function being indicative of a variation in duration time with respect to time. The duration time for a dynamic POI is the time that the dynamic POI remains in a first state before changing to a second state following initiation of the first state. Data indicative of the duration time for the dynamic POI is obtained by identifying an applicable duration time function from the database based upon at least the geographic location of the POI, and the identified duration time function is used to determine a duration time for the dynamic POI for a time of interest.
