Version 0.25.0 (07.12.2015)#

Bugfixes#

• Simulation
  • Fixed crashing and deadlocks when performing routing in the simulation based on districts. #1938
  • Fixed bug that was hindering lane-changes due to invalid cooperative speed adaptations. #1971
  • Fixed bug that was causing erratic lane changes when using subsecond simulation. #1440
  • Fixed bug that was causing erratic lane changes in front of intersections. #1856
  • Fixed right-of-way in regard to vehicles that were driving across the same intersection twice. #2023
  • Vehicles waiting to enter a roundabout no longer yield to other vehicles outside the roundabout. #1847
  • Pedestrians no longer walk past their specified arrival position. #1780
  • Fixed asymmetrical pedestrian behavior when walking to a busStop. Now they always walk to the middle of the busstop rather than to its endPos. #1562

• sumo-gui
  • Fixing crash when selecting Show all routes from the vehicle menu.
  • When loading a gui-settings-file from the View Settings dialog, the delay value is now correctly applied.
  • Fix bug that caused giant circles to appear when exaggerating the width of lanes with short geometry segments.
  • Vehicle names are now drawn for vehicles that occupy multiple edges. #1960
  • Fixed drawing of link indices, link rules, lane markings and bus stops for left-hand networks.
  • Fixed error when reloading a network with <param>-elements. #1979

• netconvert
  • Fixed missing connections in multi-modal networks. #1865
  • Fixed bug that caused invalid pedestrian crossings to be generated after importing a .net.xml file. #1907
  • Fixed bug that caused pedestrian crossings to change their priority when importing a .net.xml file. #1905
  • Fixed geometry bug when building pedestrian crossings and walkingareas for left-hand networks.
  • Fixed invalid network after deleting edges at a joined traffic light with controlled pedestrian crossing. #1902
  • Motorway ramps are no longer guessed if the lane permissions indicate that the edge is not a motorway. #1894
  • Motorway ramps are no longer guessed at roundabouts. #1890
  • Fixed some cases when roads where invalidly guessed to be roundabouts. #1933
  • When importing a .net.xml file the resulting network is no longer modified due to automatic joining of edges that connect the same nodes. #1930
  • 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. #1730
  • Several fixes in regard to OpenDrive networks:
    • Fixed missing <laneLink> elements when exporting networks as OpenDrive. #1973
    • Now successfully importing OpenDrive networks with dead-end edges. #1692
    • Fixed imprecise geometry when importing OpenDrive networks.
    • Fixed imprecise geometry when exporting networks as OpenDrive. #2031
    • Fixed invalid geometry of lanes within intersections when exporting networks as OpenDrive.

The edges that lie within the traffic light are now controlled according to the appropriate right of way (This does not necessarily model physical traffic signals but reflects the behavior of drivers). #812
    • Old signal plans for these joined traffic lights no longer work for new networks since more link states need to be defined. The option --tls.uncontrolled-within <BOOL> was added to build networks that are compatible with old-style signal plans. Note, that this may create unsafe intersections, causing collisions.

• netedit
  • When renaming an edge, the lane IDs are now updated as well. #1867
  • Fractional widths can now be set when inspecting edges.
  • Modifying traffic light plans which control multiple nodes is now working. #2009

  • osmWebWizard.py no longer nests output directories when generating multiple scenarios.

Enhancements#

• Simulation
  • Vehicle types now have vClass="passenger" by default. Earlier, the default was ignoring which would let the vehicles drive along footpaths and railways.
  • Zipper merging is now supported (see netconvert enhancement below). #1292
  • Added person statistics to verbose output. #1898
  • Now warning about jammed pedestrians.
  • Now warning about pedestrians "collisions".
  • Now warning about traffic lights where one link never gets a green light.
  • It is now possible to modify the offset of an existing tls program without loading a completely new tlLogic-definition. #1940
  • 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. #1911
  • 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>. #1958
  • Traffic detectors which are generated for actuated traffic lights now support additional parameters to allow writing output files the same way as regular detectors. #1839
  • Angles in simulation output and TraCI results now conform to Navigational Standards with 0 pointing towards the North and 90 pointing due East. #1372

• netedit
  • netedit is now open. Have fun.

  • Individual lanes and selections of lanes can now be deleted when unchecking Select edges. #1895
  • A lane (or a selections of lanes) can now be duplicated by selecting Duplicate lane from the context menu. #1896
  • Selection Mode now allows additional operators when matching against a non-numerical attribute. #1923
  • Added new option Copy edge name to clipboard to the lane popup-menu.
  • Junction attribute keepClear is now supported.
  • Custom junction shapes can now be drawn by selecting Set custom shape from the junction popup-menu. This will create a modifiable shape outline. The popup-menu of this outline allows saving, discarding and simplifying the shape.
  • Added reload menu option. #2029
  • When editing traffic light plans, states can now be set for multiple links and multiple phases at the same time.

• sumo-gui
  • Persons can now be tracked by selecting Start Tracking from the context menu. #1779
  • The current route of pedestrians can now be shown by selecting Show Current Route from the context menu. #1906
  • Error messages can now by clicked for jumping to the referenced simulation object (i.e. a teleporting vehicle). #900
  • Added person statistics to network parameter dialog. #1898
  • Added new menu option Edit->Open in netedit for opening the current network (at the current location) in netedit.
  • Added new option Copy edge name to clipboard to the lane popup-menu.
  • 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. #1899
  • 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. #1970

  • Added options --geometry.remove.keep-edges.explicit <STRING> and --geometry.remove.keep-edges.input-file <FILE> to exclude edges from being modified when using option --geometry.remove. #1929
  • 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. #1859
  • 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. #1942
  • 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). #1930
  • 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"/>).

  • 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). #1988
  • Added option --crossings.guess.speed-threshold <FLOAT>. This allows setting the speed threshold above which crossings will not be generated at uncontrolled nodes (before this was hard-coded to 13.89m/s). #1819

• polyconvert
  • Added option --fill <BOOL> to control whether polygons are filled by default or not. #1858
  • Added option --shapefile.fill <STRING> to override the fill state when importing shapefiles. Allowed values are [auto|true|false].

  • Vehicles can now be located as in sumo-gui. #1487

• 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.

  • 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.
    • Multiple connections to the same lane do not result in a warning any more. (The conflict is resolved using zipper merging or priority right of way)
    • 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

    • removed some internal junctions that were not necessary
    • repositioned internal junctions so that the waiting vehicles do not overlap with foe vehicles #1611

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 #1518
  • A warning is now issued when a loaded network contains unsafe connections. #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). #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. #1661
  • Added option --device.rerouting.output <FILE> to export the travel times which are used for dynamic rerouting during every adaptation interval. #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. #1540
  • Now setting window title when loading config or net at application start.
  • Added menu for locating persons. #1276
  • The line information for a vehicle is now shown below the vehicle id and in the parameter dialog. #1563
  • The network parameter dialog now includes some statistics on the number of nodes and edges as well as the total road length. #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. #1625

• netconvert
  • read heightmaps from GeoTIFFs for instance SRTM data #1495
  • when adding sidewalks via typemap or --sidewalks.guess, permissions on all other lanes are now automatically set to disallow pedestrians. #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. #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. #1583
  • Added option --sidewalks.guess.from-permissions <BOOL>. This adds sidewalks for edges that allow pedestrians on any of their lanes regardless of speed. #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 #1605
  • Added option --junctions.corner-detail <INT> which can be used to generate rounded intersection corners. #1606
  • user-defined shapes for internal lanes, crossings and walkingareas are now supported via the new customShape-element in .con.xml files #1607
  • right-turning road vehicles will now wait within the intersection when yielding to straight-going bicycles. #1255

  • 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 routes)

• TraCI
  • Several simulation entities support named string parameters in their XML-definitions. These can now be set and retrieved via TraCI and via the python library for the following entities: Edge, Lane, Person, Vehicle, VehicleType, PoI, Polygon, Route, TrafficLight
  • Added person API methods to sumo and to the python library.
