Purpose of use

Are you reporting something you found during a research project, consulting/professional project or personal project?
Is that a funded project?

Find during personal project (during 2020 I think but cannot remember) but also impact professional and educational projects

Describe the bug

Python error when using the GTFS -> Spatialite functionality (Launch through AequilibraE GUI but I think it could be library related).

Provided GTFS is a bit large and use crazy numbers as route_id but same error occur with small GTFS. Small GTFS (cannot be provided) developp during a project and validate with Google validator lead to same error, message error only differ by the route_id ("330101" instead of "11821949021891899").

Also as route_text_color is an optionnal field, what happened if he is not present in route.txt ?

To Reproduce

Steps to reproduce the behavior:

  1. Launch GTFS to spatialite (for example with the provided GTFS : tisseo_gtfs.zip )

  2. Wait for process...

  3. error :

Don't know exactly where to put this but this is an example for frequency aggregation of a GTFS base on a date.
GTFS "network" is created from the connection between stops (stops can be merge based on name, prefix or distance) and contain frequencies. Can be used for the creation of a future PT assignment process :

Good resource! I have been working on the network data model for Polaris (a project of Argonne National Laboratory) for some time, so there are a few ideas I will be able to bring across too whenever I have some time!

The new importer solved this issue
