Changes in the 2009 releases (versions 0.10.0, 0.10.1, 0.10.2, 0.10.3, 0.11.0 and 0.11.1)

Version 0.11.1 (23.11.2009)#

  • All
    • configuration xml format changed again to <section><key value="val"/></section> (use <SUMO_HOME>/tools/10to11.py to convert from old to new representation)
    • Bugs in Dijkstra implementation fixed (affecting at least duarouter, routing with traci and automatic rerouting) (01.10.2009)
  • Simulation
    • debugged problems when loading TLS definitions with T=0
    • implemented a variable car-following model API; many thanks to Tobias Mayer and Christoph Sommer for the collaboration who did most of the work.
    • debugged occurrence of negative vehicle speeds during emit
    • reworked the mean data output (handling multiple lanes correctly)
  • netconvert
    • making projection mandatory for OSM and DLR-Navteq networks (03.09.2009)
    • removed option --rotation-to-apply - was not properly working anyway (02.09.2009)
    • removed support for "old" TIGER networks - assuming the current ones are given as shape files; --tiger <FILE> is now mapped onto --shapefile <FILE> (02.09.2009)
    • removed support for "split" Elmar networks (option --elmar <FILE>) (02.09.2009)
    • renamed --elmar2 <FILE> to --dlr-navteq <FILE> (02.09.2009)
    • renamed --arcview <FILE> to --shapefile <FILE> (02.09.2009)
      • please note, that all subsequent options have been adapted (but the old names still work as aliases)
    • added the possibility to define changes of lane numbers along an edge in XML-descriptions (03.09.2009)
    • replaced --use-projection by --proj.utm and --proj.dhdn which determine the correct parameters for the two widely used projections from the input data
    • for developers: using same loading procedure for all imported networks, see Developer/How To/Net Importer
  • dfrouter
    • debugged problems with induction loop measure with time>end time
    • debugged problems with spaces in induction loop measures

Version 0.11.0 (29.07.2009)#

  • All
    • moved to xerces 3.0
    • moved to FOX1.6
    • changes in network format (use <SUMO_HOME>/tools/net/0103to0110.py to convert from old to new representation)
      • traffic light descriptions (18.05.2009)
      • descriptions of giving lanes free / prohibiting lanes for certain vehicle classes (10.06.2009)
      • moved character sections to attributes (22.-24.07.2009), see SUMO Road Networks
    • configuration xml format changed from <section><key>value</key></section> to <section key="value"/> (use <SUMO_HOME>/tools/10to11.py to convert from old to new representation)
    • The data-folder was removed; instead the examples got a part of the tests and are generated using these.
  • NETGEN
    • random networks may now contain bidirectional edges; the probability to have an edge being bidirectional is controlled by the --rand-bidi-probability <FLOAT> with default=1 (all edges are bidirectional)
    • The default junction type (option --default-junction-type) may now be only one of "priority", "right_before_left", or "traffic_light". Building agent-based and actuated traffic lights from within NETGEN will no longer be supported.
  • netconvert
    • Nodes which have same or almost same positions are no longer joined per default.
    • Type descriptions allow a certain edge type to be discarded from being imported using the discard="x" attribute.
    • netconvert can guess roundabouts; force using --guess-roundabouts
    • corrected usage of the spread_type attribute in edges; was: defect 111 correct usage of the spread_type attribute
    • patching problems with RoboCup Rescue League import
  • duarouter
    • The default departure/arrival behavior can be controlled on the command line, now. The following options were introduced for this purpose: --departlane, --departpos, --departspeed, --arrivallane, --arrivalpos, --arrivalspeed. See also Specification
  • jtrrouter
    • The default departure/arrival behavior can be controlled on the command line, now. The following options were introduced for this purpose: --departlane, --departpos, --departspeed, --arrivallane, --arrivalpos, --arrivalspeed. See also Specification

Version 0.10.3 (30.03.2009)#

Version 0.10.2 (16.03.2009)#

  • All
    • If configuration is written using --write-config, the application stops after this step
    • The devices now also allow "NUL" or "/dev/NULL" as output file name. In this case, the output is redirected to NUL (MS Windows) or /dev/null (Linux)

    • added the possibility to copy the cursor position to clipboard
    • debugged false position information within the popup-menu of a lane
    • Tests based on SUMO tests are now also performed for sumo-gui. Thanks to Michael Behrisch for this very nice work

  • sumo-gui
    • solved bug 2163422: Simulation does not start automatically
    • refactored the visualization speed-up; instead of using a self-made hack that uses a grid, an rtree structure is now used. This should solve problems with disappearing edges and nodes and with a slow selection

    • changed the definition of triggers; the old definition is still possible, but prints a warning.
      • <trigger objecttype="lane" attr="speed" objectid="<LANE>[;<LANE>]*" ... --> <variableSpeedSign lanes="<LANE>[;<LANE>]*" ...
      • <trigger objecttype="rerouter" objectid="<EDGE>[;<EDGE>]*" ... --> <rerouter edges="<EDGE>[;<EDGE>]*" ...
