collect statistics on match failures #34

Closed drewda closed 7 years ago

drewda commented 7 years ago

Collect the number of match failures by tile and send to centralized Datastore for aggregation and analysis.

This can help us to identify regions where there may be problems with OSMLR segment coverage, OSM tagging, or the map-matching process itself.

@kevinkreiser just pointed out that we don't know "tiles" at the segment matcher. We discussed possibly sending back wayIds and a lat,lon for traces (or parts of traces) that match to roads that do not have OSMLR segments. Any sort of "tiling" would have to be done by the Datastore/query API.

Match statistics will take 2 forms: Logging to std out: this includes segment match information (including wayids of segments that are matched but not reported on) and a list of segments that will be aggregated and potentially sent to Datastore. Aggregated stats: the Reporter will track statistics on number of successful matches, number of matches that include discontinuities (invalid matches), number of matches with errors (exceed speed threshold, other errors)
