    • Fixed some cases when roads where invalidly guessed to be roundabouts. ticket1933
    • When importing a .net.xml file the resulting network is no longer modified due to automatic joining of edges that connect the same nodes. ticket1930
    • When importing a .net.xml file with pedestrian crossings and setting option --no-internal-links, the crossings and walkingareas are removed from the resulting network. ticket1730
    • Several fixes in regard to OpenDrive networks:

    • When patching an existing network with .nod.xml file, existing traffic light programs are now preserved unless changes are specified explicitly.
    • No longer patching loaded traffic light programs for new crossings if they already have the correct state size.
    • When importing a .net.xml which was built for left-hand traffic, the resulting network will also be built for left-hand traffic. ticket1880

    • Zipper merging is now supported (see Netconvert enhancement below). ticket1292
    • Added person statistics to verbose output. ticket1898
    • Now warning about jammed pedestrians.

    • It is now possible to modify the offset of an existing tls program without loading a completely new tlLogic-definition. ticket1940
    • Added option --duration-log.statistics <BOOL> which causes average vehicle trip data to be printed in verbose mode (average route length, travel time and time loss, ...) for quick evaluation of a scenario. ticket1911
    • The option --max-num-vehicles <INT> can now be used to maintain a constant number of vehicles in the network. Vehicle insertions are delayed whenever this number would be exceeded. Previously this option would terminate the simulation when the number was exceeded. To avoid a large number of delayed vehicles it is recommended to use the option --max-depart-delay <TIME>. ticket1958
    • Traffic detectors which are generated for actuated traffic lights now support additional parameters to allow writing output files the same way as regular detectors. ticket1839

    • Added new options Close edge and Close lane to the lane popup-menu. This will force vehicles (with an assigned vClass) to wait until the corresponding lanes have been reopened (also via popup-menu).
    • Added new option Add rerouter to the lane popup-menu. This will make vehicles recompute their route when entering that edge.
    • The size and color of link indices can now be customized (old gui settings files may have to be updated).
    • Average trip data (for completed vehicle trips) is now available in the network parameter dialogue when running with option --duration-log.statistics.
    • Added new junction visualization option draw crossings/walkingareas. ticket1899
    • Vehicles can now be colored by depart delay (the differences between desired and actual depart time). Depart delay was also added to the vehicle parameter dialog. ticket1970
    • Junction shapes are no longer drawn when their color is set to fully transparent.
    • The network version is now shown the the network parameter dialog.
  • NETCONVERT
    • Zipper merging is now supported via the new node type zipper. ticket1292

    • When specifying multiple connections from the same edge to the same target lane, safe right-of-way rules are now established among the conflicting connections. ticket1859
    • Added options --tls.cycle.time <TIME> to ensure that heuristically generated traffic light plans have a fixed cycle length. The new default is 90 (s) which will have no effect on most 4-arm intersections but will cause different timings for controlled 3-arm intersections and other types. ticket1942
    • Added options --edges.join <BOOL> to select whether edges that connect the same nodes (and have similar geometry) shall be joined into an edge with multiple lanes. The new default is false (before, this heuristic was always active). ticket1930
    • Street names are now imported form OpenDrive.
    • Now including sumo edge-ids in OpenDrive export if option --output.original-names is given (as <userData sumoId="sumo_edge_id"/>).
    • Now using more lane types in OpenDrive export.
    • Added option --default.junctions.radius <FLOAT> for setting the default radius of nodes. ticket1987
    • Added option --tls.left-green.time <TIME> to configure the default duration for the dedicated left-turn phase. A value of 0 disables building this phase. ticket1949
    • Added option --sidewalks.guess.exclude <STRING> to prevent guessing a sidewalk for the given list of edges.
    • Added option --junctions.internal-link-detail <INT> for setting the number of geometry points for lanes within intersections (Before, this was hard-coded as 5). ticket1988

  • POLYCONVERT
    • Added option --fill <BOOL> to control whether polygons are filled by default or not. ticket1858
    • Added option --shapefile.fill <STRING> to override the fill state when importing shapefiles. Allowed values are [auto|true|false].
  • MESO-GUI
    • It is now possible to select individual vehicles, to examine their parameters, track them and show their route just like for SUMO-GUI. ticket1932
    • Vehicles can now be located as in SUMO-GUI. ticket1487
  • Tools
    • traceExporter.py now supports exporting traces of persons when using the new option --persons <BOOL>.
    • Added option --ignore-gaps <BOOL> for traceExporter.py. When this is set vehicles will not be destroyed until the end of the fcd-file even when disappearing for a few simulation steps..
    • The osmWebWizard.py import script is now more robust in finding a suitable output directory and recovering from errors.
    • Added new tool tlsCoordinator.py which coordinates traffic lights in a network for a given traffic demand in order to create green waves for many vehicles.
    • Connection objects from networks parsed via Sumolib can now return getTLLinkIndex as well as getJunctionIndex. ticket2048

Other

    • Network version is now 0.25. New features that justify the version change are:
      • New linkstate Z and junction type zipper for zipper merging.
      • New junction type traffic_light_right_on_red. To accommodate this type of junction, linkstate 's' (stop) is now allowed in traffic light plans.

      • New network attributes lefthand, junctionCornerDetail and junctionLinkDetail
      • Note, that the network version should have been updated in 0.23.0 due to the introduction of ships but this was forgotten.
  • SUMO-GUI
    • The visualization options Show internal edge name and Show crossing and walkingarea name were moved from the Streets-tab to the Junctions-tab.

  • Misc
    • start-commandline-bat now adds python (python 2.7 in it's default install location) and <SUMO_HOME>/tools to the path.
    • Simplified runner script of Tutorials/TraCI4Traffic_Lights
