_______________________________________________Thank you for your help!
I’ve been trying to assign the busstop to the internal lane, but I’m mostly used to using NetEdit.
I want the busstop to be placed at:
<edge id=":gneJ11_3" function="internal">
<lane id=":gneJ11_3_0" index="0" speed="13.89" length="7.68" shape="-199.56,200.00 -200.20,199.40 -201.25,196.65 -201.60,192.80"/>
</edge>
This is what I added in the additionals-file.
<additional xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://sumo.dlr.de/xsd/additional_file.xsd">
<busStop id="busStop_gneEJ11_3_0" lane="gneJ11_3_0" startPos="2.44" endPos="12.44"/>
</additional>
However, it gives me the error message
Error: The lane gneJ11_3_0 to use within the busStop 'busStop_gneEJ11_3_0' is not known.
Error: Could not end a stopping place that is not opened.
Am I doing something incorrectly?
Br,
Marcus

Hello,
your method works by defining the one-way part as a junction with exclusive right of way. There are some issues with this approach outlined in https://github.com/eclipse/sumo/issues/9500 but it might still be good enough for your use case. You can actually put a busStop into a junction by assigning it to an "internal lane" (this is not supported by netedit and must be edited directly in the xml file). See https://sumo.dlr.de/docs/sumo-gui.html#investigating_internal_edges_and_lanes
There are other approaches for modelling a one-way street though:
- by defining a traffic light that guards the shared section (though this may be problematic if vehicles stop for a time in the narrow part): https://sumo.dlr.de/docs/Simulation/Traffic_Lights.html#intersection_layout_alternateoneway
- by using opposite-direction driving with a long obstacle in one direction. This makes the behavior highly asymmetrical since one direction has right-of-way and the other direction has to wait for gaps. See https://sumo.dlr.de/docs/Simulation/OppositeDirectionDriving.html

Jakob

Hello,
I’m trying to create a street where two vehicles can’t meet each other (due to too narrow street). However, I want it to be allowed for vehicles from both sides of the edge to use the street. Thus, my issue is when I want a flow in both directions, I add an edge in both directions. But since these are separated streets, the vehicles can meet.
For example in the attached files. It is important that there cannot be a vehicle at edge “gneE7” when another vehicle has begun driving on “-gneE7” or vice versa.
I’ve played around with “EndOffSet” for edges to make this possible, and it works rather well. However, this disallows me to put BusStops at the edge since the edge is shortened.
Any suggestions or ideas on how I can solve this?
Thanks in advance!
Marcus
