[sumo-user] TAZ for pedestrian routing

Jian Yang
Hi sumo users,

I've recently come across the problem of using duarouter on pedestrian trips.
In my trip file, if I use "from=xxx to=xxx" (xxx represents edge id) for the src and sink definition, the duarouter will successfully generate the .rou.xml file. 

    <vType id="ped_pedestrian" vClass="pedestrian"/>
    <person id="ped0" depart="0.00" type="ped_pedestrian">
        <walk from="152169580" to="721202194"/> 
    </person>

But if I use fromTaz/toTaz format (the taz has been defined in additional file, and one taz contains multiple valid edges that allow pedestrian), the duarouter will run into "Segmentation Fault"

    <vType id="ped_pedestrian" vClass="pedestrian"/>
    <person id="ped0" depart="0.00" type="ped_pedestrian">
        <personTrip fromTaz="sdh" toTaz="dbt"/>
    </person>

The duarouter works fine with vehicle trips on Taz definition. Does anyone know a way to applying taz-based routing to pedestrians?

Thanks,
Jian

Hi Jian,

 

which version of sumo do you have?

There were some problems with the Taz definitions for person trips, but the issue was solved on May 28th (see https://github.com/eclipse/sumo/issues/7092).

Please try downloading the latest sumo version and check if the issue persists. You can get the last version from the GitHub repository https://github.com/eclipse/sumo/ or from the Nightly Snapshots https://sumo.dlr.de/docs/Downloads.php#sumo_-_latest_development_version.

 

Regards,

Giuliana
