    • Added traffic light type "delay_based" which implements an alternative algorithm to type "actuated".

    • attribute speedFactor can use normal distributions with optional cutoff to define the distribution of vehicle speeds ticket2925
    • Traffic light related outputs have now consistent camelCase XML tags.
    • Added option collision.stoptime <TIME> which lets vehicles stop for a time after experiencing a collision before the action set via --collision.action takes place. ticket1102
    • 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. ticket3000

      • Vehicles now attempt to equalize left and right gaps if there is insuffient lateral space ticket2932
      • 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. ticket3003

      • To deal with ambiguous stop line information in OpenDrive networks, the new option --opendrive.advance-stopline <FLOAT> may now now be used to affect the heuristic that computes stop line positioning based on the border between roads and connecting roads.
    • Bus stops can now be imported from OpenStreetMap. ticket2933
    • Lanes within a network that have no incoming connection and edges that have no outgong connections are now reported. ticket2997

    • Added vehicle.setMaxSpeed and vehicle.getMaxSpeed to the C++ client. Thanks to Raphael Riebl for the patch.
    • Added vehicle.changeTarget to the C++ client.
    • To allow vehicles to run a red light, speedmode 7 can now be used instead of 14. This is much safer as it avoids rear-end collisions.

    • vehicle function moveToXY now supports the special angle value traci.constants.INVALID_DOUBLE_VALUE. If this is set, the angle will not be factored into the scoring of candidate lanes and the vehicle will assume the angle of the best found lane. For vehicles outside the road network, the angle will be computed from the old and new position. ticket2262
    • Vehicles now support retrieval of battery device parameters and retrieval of riding persons and containers as well as retrieval of laneChangeModel parameters using the vehicle.getParameter function.

  • MESO-GUI
    • Fixed invalid coloring of the gap between lanes. ticket1428

  • Tools
    • netdiff.py now correctly handles changes to spreadType and other optional attributes. ticket2722
