trying to map accessibility and Detailed_itineraries function does not return travel mode "transit"

[Shon2477]

Dear r5r developer team,

I am trying to study the accessibility of social services in Budapest by public transport, but I cannot seem to get the different functions within the r5r envirnment to include transportation mode other than walking. Here is a documentation of the issue: https://github.com/Shon2477/r5r-Timezone_issue.git

Can you please help with the issue or guide me in the right direction how to resolve this? Thanks for any help in advance.

Timezone_issue.md

Please let me know if this it the correct format of the report.

Best, Gergely

This is likely related to question 6 in our FAQ.

the link to the GTFS seems to be broken in your documentation

[Shon2477]

By the link to the gtfs you mean the gtfs file itself?

[Shon2477]

If I interpret this correctly since the routing algorithm is different is it possible that while detailed_itineraries only returns walk as a mode of travel other functions such as accessibility is taking public transport into account as well?

Yes, I cannot download the GTFS fle with the link shown in timezone_issue.md

it's possible, but unlikely.

In case you'd like to check it, you might wanna use the expanded_travel_time_matrix() function. See vignette for details.

This is the link for the gtfs file of Budapest. https://opendata.bkk.hu/data-sources When running the expanded_travel_time_matrix() function no matter how I specify the mode of transport between the origin destination pair it does not want to return transit as a mode of getting from origin to destination. Although it does return correct results for transport mode "CAR" or "BICYCLE". I have uploaded the RMarkdown to include the ettm functions as well. Timezone_issue.md. Could this mean that there is some issue with the gtfs file itself?

I have now downloaded the GTFS from the link you shared. The GTFS feed does not include a calendar.txt file. Afaik, this file is essential because it tells R5 the period during which transit services would be operating.

suggestion: Try manually including a calendar.txt file that includes start_date and end_date between 20240301 and 20240331, which seems to be the reference period in the calendar_dates.txt file.

Also, make sure to update your departure_datetime to a date within this period.

[Shon2477]

I have downloaded the newest version of the gtfs and have created the calendar.txt from calendar_dates.txt in a way that is in the updated RMarkdown . However when reinitialising the r5r_core object, respecifying the departure_datetime and running the detailed_itineraries and the ettm functions again it still only returns results with "WALK" as the only mode of transport.

[rafapereirabr]

If you simply run r5r_core <- setup_r5(data_path = your_data_path), then {r5r} will load to memory the network that was previously built. You need to either delete the network.dat file from your data path or set overwrite = TRUE. Like this.

r5r_core <- setup_r5(data_path = your_data_path, overwrite = TRUE)

@Shon2477, any update on this?

[Shon2477]

Yes, it works now thank you very much for all the help I am eternally grateful. I have some further questions regarding visualisation . I have sent an email with the details.
