npm run start fails #1

Hi folks,
Thank you so much for providing this repository.

I cloned this repo, fired the instruction npm run start and got the following response.

npm run start

Sorry for the poor documentation.

You can generate those files in the MTA_Subway_SIRI_Server repo with the following command:

./bin/updateGTFSData.js url

dancesWithCycles · 2022-04-12T13:34:34Z

./bin/updateGTFSData.js url

Hi @PaulTomchik ,
Thank you so much for the prompt reply. Is the url parameter you mentioned above the address ot the GTFS-RT feed?

Cheers!

dancesWithCycles · 2022-04-13T14:25:02Z

./bin/updateGTFSData.js

Hi @PaulTomchik ,
I am doing something wrong but I am so blind that I do not see the point. I called the following CLI instruction in the root folder of the MTA_Subway_SIRI_Server repo.

./bin/updateGTFSData.js http://data.ndovloket.nl/flixbus/flixbus-eu.zip

This instruction results in the following complain.

USAGE: An unrecognized GTFS feed source was given.
	This script expects a single command-line argument that specifies where to retrieve
	the GTFS feed data. This argument should be either "file" or "url".
	If no argument is given, the default of "url" is used.
	If "file" is specified, the GTFS feed data must be in a zip file archive
	at the path given in the GTFS config's feedDataZipFilePath property.
	If "url" is specified, the GTFS feed data will be retrieved from the url given
	in GTFS config's feedURL property, where, again, a zip archive is the required format.

I thought I am using the script in the expected way. You can use the provided URL in Firefox browser to download the GTFS feed as ZIP archive.

I am appreciating any thoughts about the point I am missing.

Cheers!

./bin/updateGTFSData.js url

Hi @PaulTomchik ,
When I use a config file instead of the CLI parameter argument to supply the GTFS-RT feed address the ./bin/updateGTFSData.js url script is executing and comes back with the following reply.

./bin/updateGTFSData.js
INFO: Because the feed source ("file"|"url") was not specified, the default of "url" will be used.
	The GTFS data will be downloaded from http://data.ndovloket.nl/flixbus/flixbus-eu.zip

}

Is this really an error? I mean, is a GTFS feed required to contain a shapes.txt file? Or is this reply rather a warning or an info and the service is running no matter if a shapes.txt file is part of the GTFS feed?

Do you know what is meant with Could not construct the GTFS Feed Handler.?

Appreciate!

Hi @dancesWithCycles

I apologize that it is not in the documentation but the GTFS Feed ZIP archive must include a shapes.txt file.

It appears that flixbus-eu.zip archive provided at the URL mentioned above does not.

Hi @PaulTomchik ,
No worries! Do you know the reason, why a shape.txt is required? I hope the reason is not the CEN SIRI Vehicle Monitoring Service. That would mean I can not convert GTFS-RT in SIRI VM for Flixbus with the current GTFS feed.

Anyhow, can you explain how/why the two repos MTA_Subway_GTFS-Realtime_to_SIRI_Converter and MTA_Subway_SIRI_Server depend on each other?

I appreciate your help and cooperation very much. Do not hesitate to reach out to me when I can do something for you in return.

Cheers!

dancesWithCycles · 2022-04-16T06:06:50Z

Hi @PaulTomchik ,
BTW, Do you know, if MTA is still running any code from about six years ago to provide SIRI services? Cheers!

PaulTomchik · 2022-04-18T14:29:19Z

Hi @dancesWithCycles ,

Sorry, but the short answer is that the shapes.txt file is currently a hard dependency. In its current form, the project would not be able to perform conversions for GTFS feeds that lack that file. It is in fact largely due to the Vehicle monitoring service, however there are likely many other places the code would break if route shapes are not available because the central data structures assume their existence. I looked for simple ways to remove the dependency but had no success. When I get a few moments I will experiment more with removing that dependency, but it may require a significant amount of work.

The MTA_Subway_SIRI_Server is a wrapper around the MTA_Subway_GTFS-Realtime_to_SIRI_Converter that provides the HTTP API (see code). In general, the design of these projects is such that specialized repos/modules could be created and composed to address specific requirements of a given transit agency--the GTFS specification is rather flexible/loose. For example, the MTA_Subway_SIRI_Server depends on repos specific to the MTA feeds.

Have you seen the MTA Bus Time SIRI Intro?

PaulTomchik · 2022-04-18T15:13:49Z

@dancesWithCycles

I have attached a ZIP archive with what ./bin/updateGTFSData.js would produce for the flixbus-eu.zip if it did not throw an error.

You can try removing the existing ./data/ directory from your MTA_Subway_SIRI_Server clone and extracting this ZIP in its place.

Hi @PaulTomchik ,
Thanks for the reminder. Indeed, I know this web page.

If you are curious to read about all of the features of SIRI, the SIRI Handbook makes for a bit of light reading.

It is a pity, that the link for the SIRI Handbook is not working anymore. Do you know how or where to get it?

Cheers!

Hi @PaulTomchik ,
Today I was exited to follow your suggestion. I did the following.

delete the original 'data' folder in the repo
copy the data folder from the zip archive you provided into the repo
run the following instructions

$ ./bin/updateGTFSData.js url
[Error: ENOENT: no such file or directory, open '/home/begerad/git/github/MTA_Subway_SIRI_Server/data/GTFS/tmp/shapes.txt'] {

  path: '/home/begerad/git/github/MTA_Subway_SIRI_Server/data/GTFS/tmp/shapes.txt'
}

getStopIDToCoords: 1.399s
getTripID2ShapeID: 2.256s
getTripID2StopIDs: 8.775s
GTFS update complete.

Is this feedback/output the expected answer for a successful GTFS feed data update. Is it what I should expect?

BTW, in the first place my plan was to set up MTA_Subway_GTFS-Realtime_to_SIRI_Converter and MTA_Subway_SIRI_Server for the Flixbus GTFS and GTFS Realtime feed. Anyhow, if this is a challenge for the long run, my first step could be to switch to a feed that includes shape files. What do you think?
