    • Rerouters now support the attribute timeThreshold which makes their activation dependent on on a minimum amount of accumulated waiting time. #3669

    • python client now supports the whole API for vehicle.setAdaptedTraveltime and vehicle.setEffort (resetting custom values or setting with default time range) by using default arguments.

      Note

      The order of parameters had to be changed to allow this. Old code will still work but trigger a warning.

Other#

    • Electric vehicles are now initialized with a maximum capacity of 35kWh and and a half full battery by default (before, the default was 0 which always made it necessary to define this).
    • --vehroute-output now includes additional vehicle attributes such as departLane and departSpeed to facilitate scenario replaying.
    • Increased maximum possible insertion flow when using departLane values free,allowed or best on multi-lane edges. #3000
    • Improvements to lateral-gap keeping when using the sublane model:
      • Vehicles now attempt to equalize left and right gaps if there is insufficient lateral space #2932
      • The semantics of attribute minGapLat where changed to define the desired gap at 50km/h and do not grow beyond that speed (before that threshold was at 100km/h)
      • Vehicles now ignore follower vehicles behind the midpoint of their own length in regard to lateral gap keeping.
    • Added option --max-num-teleports <INT> which can abort the simulation after a number of teleports is exceeded. #3003

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

  • MESO-GUI
    • Fixed invalid coloring of the gap between lanes. #1428
