Generate GTFS shapes with network analyst just generate straight lines

Question

When generating GTGS shape with network analyst almost all routs are made with rout_type 100 and are drawn as a straight line. i dont get any error messages.

In the gtfs file route  the route_type is coded like in the example under, but when i use the tool it changes to ypye 100 (other).

route_id,agency_id,route_short_name,route_long_name,route_desc,route_type,route_url,route_color,route_text_color
ATB:Line:2_5101,ATB:Authority:2,5101,Løften/Slupphaugen - Grøtte skole,,712,,,

any idea what is wrong?

thanks for the reply.

The network dataset is delivered by the Norwegian public road adminstration and i think its working fine. It is big (the whole of Norway) but 7-8 hours is still a long time...

My organization are switching from Arcmap to ArcGis Pro, so maby i just put the further work with GTFS files on pause until the upgrade is complete.

That definitely seems too long.

It's possible that there could be an issue with the locations of the stops or with your network dataset, or the relationship between the two. The tool uses the Network Analyst Route solver, and that solver will try to find a path through the network from each stop to the next stop in the sequence. If something is wrong with the network or the stop locations, it's possible that it could be searching the entire network dataset trying to find a path. If the network is large (like all of Europe, for example), that could take a really long time.

Have you tested or used this network dataset outside of this tool? If not, that's my next recommended step. Run some standard Network Analyst workflows to make sure it's working properly.

If you find out there's something wrong with the network, I can probably give you some tips on how to fix it. However, I cannot provide any more detailed help with the Generate GTFS Shapes tool because it is deprecated and no longer supported. You should switch to ArcGIS Pro and use the tools there. They are more thoroughly tested, probably run faster, and you can get full tech support on them.

followup question: 7 hours in and still on step 1 of 28... Are something wrong or is it normal to take so long time to finish?
