Changes in the 2011 releases (versions 0.12.3, 0.13.0 and 0.13.1)

Version 0.13.1 (01.11.2011)#


  • switched-off traffic lights are now put into the correct state
  • vehicles with gui shape can now be used as router input
  • updated tutorial networks
  • fixed bug in duarouter which prevented use of multiple inline routes
  • object-chooser no longer centers on unwanted objects


  • TraCI
    • Added the possibility to retrieve an induction loop's position (offset/lane) as suggested by Xiao-Feng Xie; thanks!
    • Added the possibility to remove a vehicle via TraCI
    • Added the description about how to add a vehicle via TraCI
    • Retrieve the number of still expected vehicles
  • netconvert
    • added more control over joining junctions. You can declare nodes to be joined as well as exclude nodes from joining (see Networks/PlainXML#Joining_Nodes)
    • added option --osm.discard-tls (do not use tls definitions when importing OSM)
    • added option --junctions.join-exclude ** <STRING>[,<STRING>]* ** (junctions in this list are not joined)
    • added option --no-left-connections (do not build connections to left)
    • added optional attributes 'toLane' and 'fromLane' to connection-file element 'reset' (see Networks/PlainXML#Connection_Descriptions)
    • added importer for openDRIVE files, see Networks/Import/OpenDRIVE; many thanks go to Marius Dupuis from VIRES for allowing to use the example files for tests
    • added importer for matSIM files, see Networks/Import/MATsim (actually already in 0.13.0)
    • added new plain xml input/output format plain.tll.xml which holds information about traffic lights.
    • added option --geometry.max-segment-length <FLOAT> to restrict segment length by inserting additional geometry points
    • debugged brakedown on VISUM import
    • ignore connections for explicitly removed edges (instead of throwing an error)
  • Simulation
  • jtrrouter
    • added Karol Stosiek's patch for reading more than one turn-definitions file; changes --turn-ratio-file <FILE> to --turn-ratio-files ** <FILE>[,<FILE>]* **
  • sumo-gui
    • can now switch traffic lights back on
  • Tutorials
    • moved tutorials from <SUMO_HOME>/docs to <SUMO_HOME>/tests/complex for assuring their compliance with the current version; they should though appear in the release under <SUMO_HOME>/docs
    • added a tutorial on car-following parameter calibration
  • Tools
    • added script tools/net/ <> <> <diff_prefix> which creates the plain-xml differences of two sumo networks. The set of difference files can be loaded together with <> to recreate <>. This allows for advanced scenario management.
    • added tools for dealing with turn-ratios
  • Documentation
    • restructured wiki-pages
    • new static HTML docs generated from the wiki


  • updated gl2ps to version 1.3.6
  • removed MSMsgInductLoop; the functionality was almost the same as for a plain MSInductLoop just that an additional string was given; the functionality can be easily obtained by using proper ids and mapping them to "messages"

Version 0.13.0 (13.07.2011)#

We are using the change of the minor release number as an opportunity to clean up some things. The network format, option names, and XML element/attribute names were changed.

Network Format#

For the network, we try to rework it the way it happened the last times, too:

Networks generated by SUMO 0.12.x can still be loaded and you may find a script <SUMO_HOME>/tools/net/ which converts a network into the new format. All things marked as deprecated in version 0.12.x are now not functioning anymore. This means, you can not load networks generated by versions before 0.12.0. Networks generated by the current version can not be loaded into old SUMO versions.

  • Tags
    • removed <lanes> and <logic> elements
    • replaced <succ> and <succlane> elements by <connection>. Dummy connections (SUMO_NO_DESTINATION) are no longer written.
    • replaced <row-logic> and <logicitem> elements by <request> (within <junction> elements)
    • renamed element tl-logic to tlLogic
    • renamed element district to taz
    • renamed element dsource to tazSource
    • renamed element dsink to tazSink
  • Attributes
    • renamed attribute min_dur to minDur
    • renamed attribute max_dur to maxDur
    • renamed attribute maxspeed to speed
    • renamed attribute linkno to linkIndex
    • removed attribute <depart>
    • added attribute <index> to lanes
    • added optional attribute <name> to edges
    • added optional attribute spreadType to edges
    • added optional attribute shape to edges
  • Values
    • junctions with traffic light now have type traffic_light (as in plain-xml)
    • renamed junction type DEAD_END to dead_end
    • edge attribute function will no longer be written in the default case (=normal)
    • edge attribute type will only be written if set
    • junction attribute shape will only be written if set

Further Input Format Changes#

  • dfrouter
    • renamed element detector_definition to detectorDefinition
    • attribute length in element vType was used to declare the length from one vehicles front bumper to the next vehicles front bumper. NOW it declares the actual physical length of the vehicle. Attribute minGap is used to declare the distance between front bumper of a vehicle and the back bumper of its leader in a traffic jam.
  • netconvert
    • added optional attribute name to plain edge input. This is used for visualisation (Street name)
    • added optional attribute endOffset to plain edge input. This can be used to shorten the usable edge/lane length when stopping (i.e. in case of pedestrian crossings)
    • added optional attribute width to plain edge input. This will be used for visualisation in future patches
    • plain edge input now supports lane specific speeds
    • plain edge input now supports edge-specific vehicle class restrictions (allow, disallow)
    • replaced element forceLength by element split with altered functionality

Option Names#

Many options have been renamed to increase consistency and to hopefully make them easier to understand and remember. All changes apply to options given via the command line as well as options declared via configuration files. The old options still work although some are now marked as deprecated.

Call <APPLICATION> --save-template <filename> --save-commented to get a list of supported options including synonyms.

Application-Specific Changes#

  • Simulation
    • removed emitters, now only normal route files are allowed
    • renamed --emissions-output to --summary
    • renamed --sloppy-emit to --sloppy-insert
  • netconvert
    • now fully supports import of SUMO networks
  • TraCI
int length = readByte()
if length==0:
length = readInt()
