      • Fixed error that prevented violating right-of-way rules in the sublane-model. #3140
      • Fixed bug that was preventing speed adaptations for strategic changing. #3183
      • Fixed error that prevented changing for speed gain #3107, #3186
      • Insertion with departPosLat="random" departPos="last" is now working. #3191

    • Emergency vehicles (vClass="emergency") may always overtake on the right.
    • The default car following model can now be specified on the command line with --carfollow.model. #3142
    • Routing with --routing-algorithm astar is now working efficiently when using traffic assignment zones. #3144
    • Lanechange-output now includes the type of the changing and the longitudinal gaps on the target lane. #3156
    • Stops on internal lanes may now be defined.
    • Aggregate trip information generated via option --duration-log.statistics now includes vehicles that were still running at simulation end if the option --tripinfo-output.write-unfinished is also set. #3209

    • Tripinfo-output now includes additional attributes for persons and containers stages (depart, waitingTime, duration, vehicle, arrivalPos, actType). #3305
    • Added new lanechangeModel parameter lcAccelLat to model lateral acceleration in the sublane model. #3371

  • sumo-gui

    • All <param> values of simulation objects (i.e. TLS) can now be inspected. #3098

    • Calibrators can now be defined for specific lanes not just for the whole edge. #2434

      Caution

      To obtain the old behavior, calibrators must use the attribute edge. When using the attribute lane the new behavior is activated.

    • 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. #2464
    • POIs which are defined using attributes lane and pos now accept the optional attribute posLat for specifying lateral offset relative to the lane. #3339. These attributes are automatically added as generic parameters retrievable via TraCI.
    • Added option --tracker-interval <FLOAT> to configure the aggregation interval of value tracker windows. Previously this was fixed at 1s. Now it defaults to the --step-length value.
  • netconvert
    • <split>-definitions now support the attribute id to specify the id of the newly created node. Two-way roads can be split with the same node by using the same id in two split definitions. #3192
    • Variable lane widths are now taken into account when importing OpenDrive networks. The new option --opendrive.min-width <FLOAT> is used to determine which parts of a lane are not usable by the vehicles (default 1.8m). #3196
    • Added option --tls.red.time <TIME> for building a red phase at traffic lights that do not have a conflicting stream (i.e. roads with a a pedestrian crossing in a network that is not meant for pedestrian simulation). The new default value is 5 seconds. #1748
    • Added option --tls.allred.time <TIME> for building all-red phases after every yellow phase. #573
    • Added option --walkingareas to allow generation of walkingareas in networks without pedestrian crossings. #3253
    • Added option --opposites.guess.fix-lengths <BOOL> to ensure that opposite lane information can be set for curved roads. (see Simulation/OppositeDirectionDriving#Limitations).

    • Added options --tls.min-dur <TIME> and --tls.max-dur <TIME> for defining the time range of non-static traffic lights. #3329
    • The option --proj.scale now accepts arbitrary floats and can be used to scale the output network. #3351

    • Added button for calibrating lane/edge colors to the current value range. #2464
  • duarouter
    • Routing with --routing-algorithm astar is now working efficiently when using traffic assignment zones. #3144
    • Stops on internal lanes are now supported. #3174
    • Pedestrian <walk>s may now be defined using attribute route. #3302
  • dfrouter
    • Added option --randomize-flows for randomizing the departure times of generated vehicles.

Other#

  • SUMO now uses C++11
  • specifying the car following model as nested element in a vType is now deprecated
  • trips without ids are deprecated
  • router options are now more consistent with simulation options
    • use -a for additional files
    • use -r or --route-files for all kinds of route input (trips, flows, routes, alternatives)
    • the old options --flows, --trips, -- alternatives are deprecated
    • The network argument for routeStats.py is now optional and set with option -n.
  • The option proj.shift which used to be an alias for --proj.scale is no longer supported. These option were used to set a scaling factor by negative powers of ten but now --proj.scale sets the scaling factor directly (the previous value 5 now corresponds to 1e-5)
  • default detector-gap for actuated traffic lights is now 2.0s. #3340
  • default minGapLat value (used by the sublane model is now 0.6m (down from 1.0m) to better match observations.
