This is a first draft of Kalman (for travel times) and RLS(for dwell times) for frequency based services.

Problem with historical average as it is failing to calculate duration. This is likely to do with new cache implementations. It is reverting to the "last vehicle" method of generating a prediction.

17:29:55.680 Cannot add to FrequencyBasedHistoricalAverageCache as cannot calculate stopDuration or pathDuration. : Arrival   [vehicleId=1120, time=09-10-2018 11:29:54.064 EST, route=C, rteName=C, directionId=null, stop=119, gtfsStopSeq=4, stopIdx=3, freqStartTime=Mon Sep 10 12:26:24 EDT 2018, stopOrder=-1, avlTime=11:29:55.658 EST, trip=5, tripIdx=0, block=5, srv=Mo, cfg=0, pathLnth=422.90m]

Reloading cache from database on startup, for freq based services, not working.

scrudden commented 6 years ago

The prediction accuracy module is not working for frequency based services.

This seems to relate to the original GTFS I used for Bullrunner not having a direction for a trip.
