Re: [sumo-user] vehicles teleport over junctions
When simulating huge cities, the coarser model conserves computation effort. Also, when using the mesoscopic model, the junction internals are not modelled so this is a way of preserving route lengths.

Out of curiosity: why could having no internal links in the simulation be desirable?

When the option --no-internal-links is enabled, streets are made artificially longer so that the total route length matches the geometrically traveled distance despite "jumping" over intersections. The vehicle positions are interpolated to compensate (resulting in visually short distances while queued).
Whereas other lane-based objects such as InductionLoops are also placed at interpolated positions, the E2 detectors are drawn in the wrong spot resulting in the reported mismatch between TraCI and GUI (now tracked at https://github.com/eclipse/sumo/issues/4288).

    Dear all,

    found the culprit: the option 'no internal links' was switched on in
    NETEDIT, I am unsure how that happened. I only found out by
    comparing my network to a previous one I built.
    The 'no internal links' option seems somewhat odd, as vehicles are
    not displayed on their actual position. I.e., TraCI will then report
    E2 detectors with vehicles on them, that in the UI are actually not
    occupied (yet/anymore).
    Anyway, it works like a charm once again!

    Greets,
    Menno

        Dear all,

        in a network I made I am experiencing behaviour of vehicles that
        seems odd. The vehicles drive normally, but upon reaching a
        junction, teleport to the other side. Also, while waiting for a
        traffic light, they seem not to leave any distance between them.

        I am unaware of having changed any defaults with respect to
        behaviour. The network was made using a recent development
        version of NETEDIT, the traffic lights are controlled using
        TraCI. Is there a setting I can use to correct the described
        behaviour?

        Thanks, regards,
