Systems and methods for identifying a direction name associated a transit trip along a transit line for use in, for instance, grouping departure times or arrival times associated with transit trips at a transit stop are provided. Data indicative or an ordering ranking the plurality of transit stops in terms of importance can be accessed. Important transit stops between the reference transit stop and an ending transit stop associated with a transit trip can be identified using the ordering of the plurality of transit stops. The station names associated with the identified important transit stops can be used as a basis for the direction name associated with the transit trip at the particular reference transit stop. Departure times can be grouped by the identified direction names and using other parameters, such as by headsign.
