Re: [sumo-user] e2 detector inside junction? 
Hello,
thanks, it worked now. Before, I think I did not open the network with internal lanes in SUMO. Now I was able to place a detector inside the junction!

Hello,
in order to place detectors within junctions your network must be built with internal lanes (http://sumo.dlr.de/wiki/Simulation/Intersections#Internal_links).
- you can show the internal edge ids by setting 'show internal edge name' in the junction visualization settings (lanes have the suffix '_n' where n = 0 refers to the rightmost lane of the internal edge). - if you disbable 'draw junction shape' in the junction visualization settings you can see the internal lanes and right-click them to get their id - it helps to draw lanes at reduced width as explained here: http://sumo.dlr.de/wiki/SUMO-GUI#Investigating_internal_edges_and_lanes

    Hello Jakob,

    thanks for the info. I'd like to try this, but have trouble finding
    the internal lane IDs.

    Checking "show internal edge name" in View Settings (in SUMO-GUI)
    has no (visible) effect. Checking "show lane to lane connections"
    shows some straight lines, though not all connections are drawn.
    Also, the connections cannot be selected, and hovering over them
    does not show an ID.

    I also noticed that in the network file, all junctions have this:
    intLanes="". Also, at the top of the file it says
    "<no-internal-links value="true"/>". This seems to be an implicit
    settings, at this option was not checked in the Processing Options
    window (F10). After checking is, saving, then unchecking and saving
    again, the intLanes property is filled with data.
    I am however still unable to view them in SUMO-GUI. Using the IDs
    that show up in the network file does not seem to work (also I don't
    know which is which).

    Am I missing something?

    Greets, Menno

        Hello,
        you can place detectors on so-called internal lanes.
        This should be considered experimental and there is currently no
        support for this in netedit.
        You must obtain the lane id corresponding from sumo-gui as
        explained here:
        http://sumo.dlr.de/wiki/SUMO-GUI#Investigating_internal_edges_and_lanes
        <http://sumo.dlr.de/wiki/SUMO-GUI#Investigating_internal_edges_and_lanes>
        Note, that for left-turns the connection may consist of two
        consecutive lanes.
        regards,
        Jakob

             Hello all,

             for an intersection I'd like to simulate, I need to have E2
        type
             detectors inside a junction (ie. on a connection). Is this
        somehow
             possible? (Preferably with netedit...)

             Alternatively, also helpful would be to be able to place a
        traffic
             light stop line at an arbitrary position on an edge
        connected to a
             controller junction. That way, I could have a detector
        after the
             stop line.

             Thanks for any help,

             Greets, Menno
