Hi Ryusuke,
"from" and "to" attributes of flows always refer to edges, not junctions.
If you want to use junctions to define start and end locations, please use
attributes "fromJunction" and "toJunction" instead. Additionally you'll
need to call sumo with the argument --junction-taz true in this case. You
can find a paragraph
<https://sumo.dlr.de/docs/Definition_of_Vehicles%2C_Vehicle_Types%2C_and_Routes.html#routing_between_junctions>
about it in the docs, too.
Best regards
Mirko

Betreff: [sumo-user] Questions about "flowID"

Hello!
My name is Ryusuke Masahira.
I'd appreciate if you could answer this question.
I have a question about what to write for "flowID", "from" and "to" in the
rou.xml file.
I entered a name I decided on for "flowID".
For "from" and "to", I entered the "junction" values of the departure and
arrival points in the map data specified in net.xml.
When I run it, I get the error "Error: The edge '1481887607' within the
route for flow 'f_0' is not known.
The route can not be built."
I’m sorry to bother you with this email.
