Re: [sumo-user] OSM, netconvert and public transports. 
Thank you, Jakob.
I extracted those data straight from OSM, that is why I was asking what have I done wrong during the extraction. I'll check what Mirko posted concerning tags, and then (if is still not working) I'll do it myself. 

Regards,
Lara

Hello Lara,
I think its much simpler to generate the ptstop and ptline files directly if you are generating public transport data from some third-party data source anyway. The format of the stop file is documented in the wiki and the ptlines file should be self-explanatory (we plan to add documentation in the wiki for that as well, just didn't get around to it yet). If your data source includes schedule information you can forgo to ptlines file as well and just generate the route file (ptlines are used as an intermediate format to encode public transport routes without schedule information).

Jakob

    Hi Lara,

    you can find the responsible file in the SUMO source at
    src/netimport/NIImporter_OpenStreetMap.cpp. The OSM tags can be
    found in the methods of the EdgesHandler and the NodeHandler but
    seem not to be summarized anywhere. Some examples related to public
    transport I've found in a short time:

    line 697 and further
    (NIImporter_OpenStreetMap::NodesHandler::myStartElement):

    /        if (key == "highway" || key == "ele" || key == "crossing"
    || key == "railway" || key == "public_transport"//
    //                || key == "name" || key == "train" || key == "bus"
    || key == "tram" || key == "light_rail" || key == "subway" || key ==
    "station") /

    Regards
    Mirko

    Dear All,

    I built an OSM-like topology and I'm trying to use netconvert
    (with ptstop and ptline) to extract the public transports.
    I thought I included all the relations/ways/nodes required, but
    the files are empty.

    Can someone point me to the OSM tags that netconvert looks for in
    order to build/extract the public transports, so I can build my
    OSM-like topology in the right way?

    Best Regards,
    Lara

    Dear All,

    I'm building a mobility scenario from an OSM-like topology and I
    have various issues here and there.

    1) walking areas
    I'm building a scenario for pedestrian too, but if I use the
    options "sidewalks.guess", "crossings.guess", and "walkingareas",
    the resulting netfile has many of the connection tagged
    "walkingarea" broken (I't duarouter that points it out). Is there
    something that I'm missing or is it "normal" and I have to fix
    them by hand?

    2) od2trips, zones, and vTypes
    the taz are defined with a name and a list(string) of edges (all
    edges can be start and sink with the same probability), but in
    the same edge, I may have different allowed vehicles depending on
    the lane.
    At the moment I have one complete zones definition that ignores
    the allowed vTypes, but when I use it with od2trips, the flows
    file and the trips file are both kind of unusable by duarouter or
    sumo. If I use taz and flows, duarouter gives me only the
    starting edge and it does not compute the full route, and sumo
    uses only one starting point for each taz. If I use the trips
    with duarouter, too many of them are broken because the (origins)
    destinations are unreachable (due to the vehicles not allowed on
    the edge)
    Is there a simple solution for this issue? Am I using the tools
    in the wrong way? (probably yes)
    Do I have to write different taz based on the vTypes allowed?
    Remember: in the same edge, I may have different allowed vehicles
    depending on the lane.
    The last resource is to implement my own od2trips that uses only
    the right edges, hoping that duarouter (that is able to read my
    vTypes definitions) will compute the right route.

    There are too many big files involved and I cannot share them on
    this mailing list.
    In case of need, I can privately share the repo.

    Thank you in advance for the help.

    Regards,
    Lara
