Context

PR#48 was created by @timMillet 2 years ago, and there seemed to be a consensus on the changes. However, the discussion stopped and the changes have not been merged yet. Since the old branch is 45 commits behind the current master(current flex proposal), I am creating this new PR to include [all previous proposed changes + typo revision + a tiny change based on a suggestion from comment] to the current proposal.

(side note: this PR doesn't include what we discussed on issue#73, plan to create another PR for that)

Changes in this PR include:

-Quote from PR#48

  • Better definition of the "mean" and "safe" concepts
  • Replace "travel" durations (rider-oriented) by "trip" durations (vehicle/service-oriented)
  • Define when the trip durations start and end
  • Consistency and complementarity with wait time definitions in GOFS phase 1: Service Discoverability (Draft)

-New changes

  • Revise typo (represents the average time the rider travels.....)
  • Replace "Mean" by "The mean trip duration"

For previous discussion, please see PR#48.

@timMillet @westontrillium @tsherlockcraig could you please have another look at this PR? If this looks ok we can merge to current proposal.

Replace "travel" durations (rider-oriented) by "trip" durations (vehicle/service-oriented)
For mean_duration:
- Better definition of the "mean" and "safe" concepts
- Define when the trip durations start and end
For safe_duration
- Better definition of the "safe" concept
- Define when the trip durations start and end
- Replace "SafeTravelDuration" by "SafeTripDuration"

This looks like an improvement but I think that we should remove "based on historical data" from both definitions. I can see basing these factors/offsets on historical data as a best practice, but historical data won't always be available (e.g., new service, but also due to lack of data for existing services), so we shouldn't imply that it is required.

@tzujenchanmbd Are you going to transfer this over to google/transit before we close this repository?
