    • Fixed deadlock when vehicles with triggered stops could not load passengers or containers due to capacity constraints.
    • Fixed invalid edge travel times used for dynamic routing in case flow differs among the lanes. #2362
    • Fixed invalid edge travel times used for dynamic routing due to invalid averaging #2351
    • Fixed invalid time stamps for leave times and an off by one for instant induction loops #1841

    • Fixed bug where the simulation would not terminate when using calibrators. #2346
    • The options --meso-tauff and --meso-taufj now define net time gaps (default values were changed accordingly). The gross time gaps are computed based on vehicle lengths and edge speed to allow for more realistic flow in networks with widely varying speed limits. This also affects the threshold that defines jamming when using default options (thresholds based on allowed speeds). #2364
  • netconvert
    • Fixed connection-guessing heuristic. #1992, #1219, #1633, #2398
    • Option --remove-edges.by-vclass is now working when loading a .net.xml file. #2280

    • Fixed retrieval of exit times for vehicles that spend multiple steps on an inductionloop when retrieving last step vehicle data (0x17). #2326

Enhancements#

  • Simulation
    • Added model for sublane-simulation. This is activated by setting the option --lateral-resolution <FLOAT>. When using this option, vehicles may move laterally within their lanes. This is influenced by the new vType-attributes latAlignment, maxSpeedLat, minGapLat. Lane changing is performed according to the new lane changing model SL2005.
    • Lane-changing models can now be configured with additional vType parameters. There exists one parameter for each of the lane-changing motivations strategic,cooperative,speedGain and keepRight which can be used to increase or reduce that type of lane changing. #1136
    • Added capabilities for overtaking through the opposite-direction lane.
    • Added new option --collision.action <STRING> for configuring the action to take on vehicle collision. Allowed actions are none,warn,teleport and remove. The default is teleport which moves the rear vehicle involved in a collision onto a subsequent lane (as before).
    • Added new option --collision.check-junctions <BOOL> to enable geometrical collision checking on junctions. By default this option is set to false and collisions between non-consecutive lanes are ignored as before. This option may slow down the simulation. #984
    • ChargingStations can now be used to declare vehicle stops. #2248
    • the vehicle route output now includes optional vehicle parameters as param entries
    • Added new option --device.rerouting.adaptation-steps <INT> to switch the default algorithm for averaging edge travel times from exponential averaging to a moving average over the given number of steps. #2374
    • Added new option --tls.all-off <BOOL> for switching off all traffic lights (the traffic lights can still be switched on via GUI or TraCI). #2442
    • Added new output for tracking lane change events. This is enabled using the new option --lanechange-output <FILE>. #2461
  • MESO
    • The option --meso-jam-threshold <FLOAT> now gives additional freedom when configuring a speed dependent jam-threshold. When an value below 0 is given the absolute value is taking as a factor for the minimum unjammed speed. Thus, negative values closer to 0 result in less jamming. The default value remains at -1 and results in the original behavior (values above 0 set the occupancy fraction threshold independent of edge speed as before).
  • sumo-gui
    • The number of running vehicles and persons is now shown in the status bar. This display also acts as a button for opening the network parameter dialog. #1943
    • Charging stations are now shown in a different color when active.
    • Persons are now more visible when selecting Draw with constant size when zoomed out.
    • Added the averaged speeds that are used for simulation routing to the lane parameter dialog.

    • Can now color edges by the averaged speeds that are used for simulation routing.
    • Can now color edge segments (mesoscopic vehicle queues) individually by various traffic measures. #2243
  • netconvert
    • Added option default.lanewidth <FLOAT> for setting the default width of lanes (also applies to netgenerate).
    • Added option numerical-ids <BOOL> for forcing all node and edge IDs to be integers (also applies to netgenerate). #1742
    • Added Option speed.minimum to avoid negative speeds when using Option --speed.offset. #2363
  • netedit
    • Many additional network structures such as busStops, detectors and variable speed signs can now be defined and manipulated. #1916
  • netgenerate
    • Added option grid.alphanumerical-ids <BOOL> for using a chess-like intersection naming scheme (A1, B3, etc).
  • TraCI
    • Added vehicle command next TLS to retrieve upcoming traffic lights along a vehicles route. #1760
    • The vehicle command move to XY (formerly move to VTD) now supports an additional flag which selects whether the original route shall be kept or the route may change and whether the vehicle may leave the road network. #2033, #2258
    • The vehicle command move to XY now allows moving vehicles that are still in the insertion buffer.
    • Added functions vehicle.add, vehicle.remove and vehicle.moveToXY to the C++ TraCI API client
    • Added object variable subscriptions and context subscriptions to the C++ TraCI-library (subscribe, getSubscriptionResults, subscribeContext, getContextSubscriptionResults). Thanks to Erik Newton for the patch.
    • Added person value retrieval functions to the C++ TraCI API client. Thanks to Caner Ipek for the patch.
    • Added vehicle command get speedmode 0xb3 to retrieve the speed mode of vehicles. #2455
    • Added vehicle command get slope 0x36 to retrieve the slope at its current position #2071

  • TraCI
    • TraCI version is now 12.
    • The vehicle command move to VTD is now referred to as move to XY in client code. #2032

Enhancements#

  • sumo-gui
    • Adjusted zooming distance when centering on simulation objects to make objects easier to find. #2146
    • Added option --waiting-time-memory <TIME> for tracking accumulated waiting time of vehicles. The accumulated waiting time (seconds of waiting time within the configured interval, default 100s) can be inspected in the vehicle's parameter window and the vehicles can be colored according to this value. #999

  • MESO
    • Added option --meso-tls-penalty <FLOAT> as an alternative way to model the delay effects of traffic lights. When this option is set to a positive value, the expected delay time for each controlled link (based on red duration and cycle duration) is added to the travel time, multiplied with the <FLOAT> argument. By calibrating the parameter, the quality of TLS coordination can be modeled. #2199
  • MESO-GUI
    • Coloring vehicles by depart delay is now working. Added depart delay to the vehicle parameter dialog.
    • Added event time, entry time and block time to the vehicle parameter dialog. These values record when a vehicle leaves, entered and was blocked on an edge segment.

    • Added new simulation command save state 0x95 for saving the current simulation state. #2191
  • Tools
    • tls_csv2SUMO.py now handles controlled edges within a joined traffic light definition automatically.
    • Added option --ignore-connections to netcheck.py. This can be used to compute all components in the node graph without considering lane-to-lane connections.
    • Added option --symmetrical to generateBidiDistricts.py (previously undocumented tool). This can improve opposite-finding in conjunction with option --radius.
    • Added option --geo to route2poly.py. This can be used to visualize routes from one network within another network.
