[Spain] Palma de Mallorca 0 seconds trip duration due to missing timepoint values

[GerdC]

Bus legs inside Palma de Mallorca have durations of 0 seconds. Example:

Reason are missing timepoint values a can be seen here for example https://busmaps.com/en/spain/public_transit-line-1-2413739300-2494502523

Data comes from EMT Palma https://www.emtpalma.cat/ca/inici

Alls stops appear to be used, according their own plan: https://www.emtpalma.cat/ca/linia/-/L/1/portopi-sindicat

Primary gtfs data source: https://www.emtpalma.cat/en/open-data-en

gtfs validation report for example https://busmaps.com/en/spain/Empresa-Municipal/emtpalma

I'll try to nudge them via contact page https://www.emtpalma.cat/ca/atencio-al-client but I'm surely not the first.

As the first and last (and a few intermediate) stops have timepoint values, the timepoints at intermediate stops times might be interpolated.

Appears to be a good time to nudge them https://www.mallorcazeitung.es/mobilitat/2024/09/20/emt-busse-app-probleme-108351746.html
Maybe it's good if I'm not the only one.

I asked them via contact form.

I analyzed the problem. They put a space for the stop time which is not "empty" (space between commas , ,).

If exact arrival and departure times (timepoint=1) are not available, estimated or interpolated arrival and departure times (timepoint=0) should be provided.

Regarding timepoint the specification says:

If no timepoint values are provided, all times are considered exact.

When implementing MOTIS, I used this example which uses empty stop times (nothing between commas: ,,):

I will change the check to ignore whitespace (trim before empty check). This will solve this issue. Then MOTIS will interpolate the times.

Release v2.0.7 should fix this issue (haven't tried, just added trim before the empty check):

• release: https://github.com/motis-project/motis/releases/tag/v2.0.7
• commit: motis-project/nigiri@e5b1a20

🤔 This issue seems to persist on api.transitous.org

[felixguendling]

Should be fixed now (again). It was shortly fixed but then I added a "monotonicity enforcer" which eliminated the value indicating that a timestamp should be interpolated later on. Now the monotonicity enforcement is on UTC times (after expansion of frequencies, etc).

This bug seems fixed now :)
