Re: [sumo-user] Mapping of GTFS data to network error
Hi,

I have read and done the tutorials. I was thinking the issue might be that the gtfs2pt script was mapping the bus stops using some geometries that my map didn't have (I only downloaded drivable edges so my map did not have bus stop information).

I just tried the option --skip-fcd but it also didn't work. Currently I am downloading the entire OSM map using the osmWizard (road and geometries) and will see if it works.

Thank you very much for the quick response.

Hi,

have you tried the osmWizard from SUMO to create your net?

Hi,

unfortunately I'm not an GTFS expert, but have you read the tutorial? https://sumo.dlr.de/docs/Tutorials/GTFS.html

Which version of SUMO are you using?

From the sources I can conclude, that gtfs.py uses as default mapping  a file lib/fcd-process-chain-2.2.2.jar.

Have you tried the option --skip-fcd?

Best Harald

Hi all,

I am currently trying to map my GTFS data to the OSM network I downloaded using OSMnx (network_type=drive). I converted the OSM data (only nodes and edges) to the sumo network file via netconvert.

I don't know exactly how the gtfs2pt.py script works but I am getting this error message after running it with this command:

Command:
python "C:\Program Files (x86)\Eclipse\Sumo\tools\import\gtfs\gtfs2pt.py" -n tokyo_drive.net.xml --gtfs BUS-GTFS_20211007.zip --date 20211103

Error:
Success.
Warning! No mapping library found, falling back to tracemapper.
Warning! No net resources\gtfs\bus.net.xml

Am I correct to assume that the gtfs2pt.py script is trying to map each bus stop to an edge by using a map matching algorithm? Or does the mapping rely on geometries (e.g. public_transport=bus_stop)? 

Since I can't seem to make it work, I was planning to manually extract the data from the GTFS file and match the bus stop to each edge by finding the nearest edge using the closest euclidean distance of its (lat, lon) pair. The challenge is on how to know which lane of the edge to match it to and the order of the edges that the buses will traverse within the assigned route. I was hoping to get some insight into how the gtfs2pt.py script is calculating it.

Thank you.
