    • fixed rerouter interval ends which are now exclusive like all other intervals
    • fixed bug that caused invalid exit times when vehicles were teleported while on an intersection. Issue #1520
    • fixed invalid estimation of the time and speed when reaching an intersection which could cause collisions. Issue #1531 Issue #1533
    • explicitly setting option --weight-attribute traveltime now properly fills the edge-weight container (i.e. for visualization). Issue #1541
    • fixed invalid routeLength in --tripinfo-output when vehicles did not finish their route. Issue #1539
    • fixed invalid routeLength in --tripinfo-output when using networks with internal lanes. Issue #443

    • several fixes to the placement of internal junctions (waiting positions on the intersection for selected connections)
      • removed some internal junctions that were not necessary
      • repositioned internal junctions so that the waiting vehicles do not overlap with foe vehicles Issue #1611
      • moved internal junctions at TLS-controlled nodes further towards the junction center (previously they respected foe vehicles which would never get the green light at the same time)
    • fixed invalid junction logic (right-of-way rules) when incoming edges had uncommon angles. Issue #1632Issue #1462
    • generate tls logic now matches the underlying edge priorities. The streams that would have priority if the node type was "priority" now always have a common green phase. Issue #1642

    • The edge width exaggeration factor is now properly saved to and loaded from a gui-settings-file.
    • fixed gui glitch when zooming with transparent lanes in view.
    • now drawing vehicles on transparent lanes.
    • Selecting the Center action from a popup-menu immediately centers the view on that object (instead of delaying until the next window update). Issue #1593
    • when an error occurs during the initial route loading, reloading the simulation will now work after the user corrects the error in the input files. Issue #1508
  • DUAROUTER
    • no longer building invalid routes when the connectivity among edges differs between vClasses. Issue #303

Enhancements

  • Simulation
    • Pedestrians now have appropriate default values for length, minGap and width. These values can be changed by using a vType.
    • Improved realism of pedestrian dynamics on walkingareas when using model striping. Pedestrians at arbitrary angles now properly avoid each other.
    • Added option --pedestrian.striping.jamtime <TIME> to control behavior of jammed pedestrians. By default, pedestrians will now start squeezing through the jam after being stopped for that time. As a consequence, pedestrian scenarios now always terminate.
    • Added option --output-prefix <FILE> to automatically add a prefix to all output files. The special string TIME is replaced with the current time.
    • Rerouters can now set permitted vehicle classes on closed lanes, see Issue #1518
    • A warning is now issued when a loaded network contains unsafe connections. Issue #447
    • A new car-following class based on the original Krauß was added that that takes into account the maximum acceleration ability computed by PHEMlight
    • Pedestrian routing now also works on networks without pedestrian infrastructure (walkingareas). Issue #1564
    • Added option --netstate-dump.precision <INT> to control the precision (number of digits after the dot) of vehicle positions and speeds when using option --netstate-dump.
    • Added vehicle class ship.
    • option --ignore-route-errors now also handles errors which prevent the vehicle from being inserted into the network. {{Ticket|1661}
    • Added option --device.rerouting.output <FILE> to export the travel times which are used for dynamic rerouting during every adaptation interval. Issue #1663
  • SUMO-GUI
    • Can now color and scale lanes by average speed and by by average relative speed (relative to the speed limit).
    • Added option for drawing the path across the current walkingarea to the person popup menu.
    • Can now color pedestrians randomly.
    • When drawing persons as triangles, the direction they are facing is now indicated (it was ambiguous for equilateral triangles).
    • The lane menu now shows the height under the cursor as well as the offset (pos).
    • Can now color lanes by height at segment start and by by inclination at segment start. This allows investigating the 3D-geometry in detail.
    • Added param show-detectors that allows showing detectors of actuated traffic lights in the GUI.
    • When drawing streets with exaggerated width, the edge in one direction no longer overlaps with the opposite direction. Issue #1540
    • Now setting window title when loading config or net at application start.
    • Added menu for locating persons. Issue #1276
    • The line information for a vehicle is now shown below the vehicle id and in the parameter dialog. Issue #1563
    • The network parameter dialog now includes some statistics on the number of nodes and edges as well as the total road length. Issue #1367
    • Added guiShape ship.
    • Now drawing waterways (lanes with allow="ship") in a distinct style.
    • Added menu option for loading an additional-file with shapes.
    • Improved gui shapes for two-wheeled vehicles.
    • Markings for bike lanes are now drawn at road intersections (bike lanes are lanes which only allow vClass bicycle).
    • Added options for saving the current viewport and simulation delay along with the current visualisation settings. Issue #1625
  • NETCONVERT
    • read heightmaps from GeoTIFFs for instance SRTM data Issue #1495
    • when adding sidewalks via typemap or --sidewalks.guess, permissions on all other lanes are now automatically set to disallow pedestrians. Issue #1507
    • sidewalks can now be added for specific edges by adding the attribute sidewalkWidth="<width_in_m>" to <edge>-elements in .edg.xml-files. This automatically remaps any existing connections. Issue #1580
    • when using pedestrian crossings and green verges (lanes which disallow all vClasses), the crossing now starts at the side of the ride instead of the green verge. Issue #1583
    • Added option --sidewalks.guess.from-permissions <BOOL>. This adds sidewalks for edges that allow pedestrians on any of their lanes regardless of speed. Issue #1588
    • Can now import waterways from OSM (needs a custom type-map).
    • The junction size can now be customized using the new <node>-attribute radius. Issue #1605
    • Added option --junctions.corner-detail <INT> which can be used to generate rounded intersection corners. Issue #1606
    • user-defined shapes for internal lanes, crossings and walkingareas are now supported via the new customShape-element in .con.xml files. Issue #1607
    • right-turning road vehicles will now wait within the intersection when yielding to straight-going bicycles. Issue #1255
  • NETGENERATE
    • can now generate networks with unregulated intersections. Issue #1558
  • POLYCONVERT
    • added option --output.plain-geo <BOOL> for writing POIs and polygons with geo-coordinates. Issue #1608

    • can now load all types of shapes from the menu.
    • can now undo/redo bulk selection/deselection of objects. Issue #1614
    • added option for auto-selecting an edges nodes.
    • can now modify the nodes of an edge via the attribute dialog. Issue #1662
    • the attribute panel is now updated on undo/redo/recompute. Issue #696
    • when creating a reverse edge with spread type center, the new edge is shifted sideways and given new endpoints.
    • can now move the view in 'Create Edge'-mode by holding <CTRL>
  • Tools
    • sort_routes.py now supports sorting persons and also copies additional elements (such as vType to the output).
    • cutRoutes.py can now handle nested stops in a vehicle definition.
    • added routeStats.py for computing statistics on route length.
    • added traceExporter.py option --orig-ids <BOOL> for keeping the original vehicle IDs instead of a running index. For some output formats such as NS2 this only works if the vehicle IDs are numeric to begin with.
    • route2trips.py now preserves vType elements.
    • server.py now starts with 'real world' gui settings and initial delay of 20. Also, the trip generation settings have been tweaked for realism (i.e. shorter pedestrian trips, longer train troutes)
