Z/Changes from Version 0.12.3 to Version 0.13.0

generated on 2019-08-26 00:07:10.171887 from the wiki page for Z/Changes_from_Version_0.12.3_to_Version_0.13.0 for SUMO git

Release Date: 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/0123to0130.py 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
  • ROUTES
    • 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 easiert 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.br

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

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()
