    • Calibrators can now be defined for specific lanes not just for the whole edge.
      Caution:
      To obtain the old behavior, calibrators must use the attribute edge. When using the attribute lane the new behavior is activated.
      ticket2434
    • When using the Sublane model, the lateral offset of left and right vehicle side as well as the rightmost and leftmost sublane are listed in the vehicle parameter dialog.
    • Added button for calibrating lane/edge colors to the current value range. ticket2464

  • default detector-gap for actuated traffic lights is now 2.0s. ticket3340
  • default minGapLat value (used by the sublane model is now 0.6m (down from 1.0m) to better match observations.

    • vehicle function moveToXY now supports the special angle value traci.constants.INVALID_DOUBLE_VALUE.
