Changes in versions 0.9.0 up to 0.9.10

Version 0.9.10 (16.09.2008)#

  • Simulation
    • solved "Simulation reports 'Error: The number of edges in the list mismatches the edge count.'"
    • solved several issues reported by Gerrit Lammert (thank you): false ordering of loaded stops, problems with stops near to an end edge
  • Guisim
    • vehicles now again have a default color
  • TraCI
    • patched building tracitestclient_main.cpp under Fedora Core 9 (thanks to Niek Sanders)
  • Tools
    • patched dua-iterate.py - --move-on-short does no longer exist

Version 0.9.9 (05.08.2008)#

  • Simulation
    • Hidden state loading/saving completely from the microsim
    • Vehicle may now end their route at a certain position of the route's last edge (see Specification)
    • The route may be now given as an attribute (route) within the vehicle definition (see Specification)
    • The vehicle now stores most of its definition parameters in myParameter, not as atomar values
    • Solved problems with multiple stop on same edge and with stops on lanes which can not be used for continuing the route; thanks to Friedemann Wesner and Gerrit Lammert for reporting them
    • Reworked mean data output. The vehicle movements are now weighted by the time the vehicle was on an edge/lane. Additional constraints for output (--exclude-empty-edges/--exclude-empty-lanes) allow to dump only information about edges/lanes which were occupied by vehicles.
    • debugged bug 1964433 different simulation results for different starting times; The issue was a false computation of WAUT switching and TLS offset times when choosing a different simulation begin time than 0
    • replaced MSVehicle::getInTransit and MSVehicle::running by MSVehicle::isOnRoad
    • removed MSEdge::isSource; was used only once and can be easily replaced by comparing the result of MSEdge::getPurpose()
    • debugged bug 1932105 second stop on the same edge confuses vehicles
    • debugged bug 1941846 repeatable crash with sumo r5378
    • debugged bug 1912547 linux 64 bit compile error for sumo svn 5143
    • debugged bug 1913655 command line sumo throws unknown exception
    • debugged bug 1924989 sumo r5186 crashes by pure virtual function call
    • begun work on Specification
      • all vehicles are emitted at position=0, with speed=0
    • removed usage of NLLoadFilter
    • added an option to quit the simulation if a number of vehicles is exceeded (--too-many-vehicles <INT>)
    • fully integrated Tino Morenz's MSVTypeProbe; moved it from microsim/trigger to microsim/output; tests added; a vtypeprobe is now defined within additional files this way: <vtypeprobe id="test1" type="" freq="10" file="vtypeprobe.xml"/> ("test1" is the vehicle type to report, leave empty in order to get information about all vehicles)
    • replaced usage of "Command" by encapsulating methods in "WrappingCommand" wherever possible
    • "debugged" usage of actuated/agent-based tls; should be covered by tests, in fact
    • further work on devices-consolidation
    • implemented a one-shot / multi-shot routing device
  • netconvert
    • debugged bug 1993928 --keep-edges.input-file does not remove empty nodes; as soon as one edge-removal(keeping) option occurs, nodes are rechecked whether they contain any further edge. If not, the node is removed.
    • VISUM-import: debugged failures due to false district node position computation
    • Connection building: made storing outgoing edge connections sane; replaced three strange storages by one
    • Disabled the support for setting an "edge function" - because vehicles are emitted the same (parametrised) way on each edge, we do not need a distinction between source and normal edges; sink edges were never distinguished.
    • Refactored the way edge types are stored in netconvert
    • removed "name" attribute from NBEdge; was not written anyway
    • work on SUMO-networks reimport (unfinished)
    • documentation: debugged bug 1909685 option "omit-corrupt-edges" not recognized (use --dismiss-loading-errors instead of --omit-corrupt-edges)
    • removed usage of NLLoadFilter
    • thanks to Christoph Sommer, the OSM importer now handles speed and lanes information; default OS values are now used, too
  • duarouter / jtrrouter
    • Removed option --move-on-short. It got obsolete as vehicles may start on edges which are shorter than they are, now.
  • duarouter
    • debugged bug 1981921 duarouter truncates routes; Now, --remove-loops only prunes the route if the vehicle would have to take a turnaround at the begin or end.
    • reworked handling of broken routes; longer routes are not replaced; incomplete routes may be corrected using the new --repair option
  • jtrrouter
    • Removed possibility to specify turning percentages using CSV files
  • dfrouter
    • Definition of emitters, vss, etc. are now written into the same folder as the declaration
  • TraCI
    • TraCI is now enabled as default
  • od2trips
    • due to being used for macroscopic demand definitions, od2trips now emits vehicles using departlane="best" and departspeed="max"
    • removed option to parse list of tables from a vissim file; they may be given at the command line (--vissim is no longer supported)
    • added the possibility to omit writing the vehicle type (--no-vtype)
  • Tools
    • added some tools for output visualization (mpl_dump_twoAgainst.py, mpl_tripinfos_twoAgainst.py, mpl_dump_timeline.py) (see Tools/Visualization)

Version 0.9.4#

This release is rather a snapshot. Many things have changed and some will require some further revalidation. There are three major changes/extensions:

1. The TLS-subsystem now allows having more than a single logic for a traffic light. One can describe the switch times and switch between them on the GUI. The user-description on this may be found under Traffic Lights. There is no developer documentation on this, yet. If you are parsing the networks by your own, you will see that traffic lights definitions have changed slightly. Instead of the sgmltag "logicno" a tag named "subkey" is used by now. Also, "inclanes" has been removed.

2. A full support to import networks with positions encoded in geocoordinates. This makes the usage of two further libraries necessary, PROJ.4 and GDAL. The new building process is described here. A description about how to import geocoordinated files (despite of ArcView-files) can be found here.

Together with this extension, the import of ArcView-files has been rechecked and now allows to import networks stored in other schemes than the one NavTeq uses. The new options are described here.

Some further comments on importing ArcView-files are available here. By now, they include only some comments on importing an open-source network of Osnabrück. You can take a look at this here and also download it from here.

3. The developer documentation has been split into several parts. It seems to be unmanageable to write a complete developer documentation. Due to this, we now offer some additional documentation on certain topics. Topics that were previously a part of the developer documentation may be now found within the More Docs section.

There are also some further changes which do not yet show their potentials, but are quite promising:

1. The routing interface has been made abstract. This allows to use routing algorithms in both the simulation as in the routing applications and will hopefully yield implementations of some further routing algorithms - by now Dijkstra and a turning ration algorithm are available.

2. Some first steps towards making SUMO be aware of vehicle types have been done. It is now possible to allow/disallow vehicles by class to use certain lanes. This is now implemented in the netconvert application and within duarouter, but not yet in the simulation itself and due to this not yet documented. But, as you can see, we are working towards making SUMO multi-modal...

The complete list of changes:

  • Multimodality
    • made lanes storing vehicle classes (additional XML-definition for lanes, Router is aware of vehicle classes) (undocumented)

    • Vision import added (see Importing VISUM-networks)
    • Positions of guessed TLS may now be saved as POIs (undocumented, yet)
