Re: [sumo-user] Mapping of GTFS data to network error
|
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.
