org.onebusaway.realtime.api.VehicleLocationRecord
Vehicle location records are the key data structure for passing real-time location data about a transit vehicle from an external data source into OneBusAway. It tries to capture a variety of fields that might be present in an AVL stream:
- block id
- trip id
- vehicle id
- location
- schedule adherence
- arrival data relative to a timepoint
Not all of these fields will necessarily be set by the AVL source, so we may have to be flexible in how we process the data. @author bdferris @see VehicleLocationListener
