Version 0.21.0 (11.06.2014)#
- Fixed infinite loop when tls-phases were shorter than the step-size
- Fixed bug where vehicles would block the intersection when stopping at the very end of a lane due to a red light
- Fixed lane-changing bug which could cause differing results between different compilers due to uninitialized memory.
- The vehicle class
ignoringnow properly ignores edge permissions and is allowed to drive anywhere.
- Time values are now checked on input whether they are in the correct range (less than 2147483 seconds)
- Teleport over an edge which has a stop now removes the stop from the list of pending stops
- the IDM and the IDMM car following model now stop closer to the halting line (in front of intersections), furthermore the moving average in the IDMM was repaired
- Bluetooth device handles subsecond simulation correctly
- Fixed check for slow lanes ahead of the depart position to allow for higher insertion speeds
- Repaired rerouting of vehicles which are on an internal lane
- Several fixes with teleporting over, on and onto induction loops and range detectors.
- Fix to the computation of the expected time at which vehicles leave an intersection. This results in a minor increase in junction throughput.
- The time shown in the gui now matches the time found in simulation outputs for the shown vehicle positions. Previously, the gui showed the time + 1 step.
- Fixed crash when drawing persons
- Patched building under macOS, thanks to Alex Voronov
- lane coloring by netto occupancy no longer shows brutto occupancy (see lane coloring).
- drawing of simple vehicle shapes now always uses a distinct color for drawing details.
- Fixed crash when closing the breakpoint editor
- Fixed crash when loading viewsettings and changing them immediately.
- when loading traffic light programs from tllogic-files, the node attribute controlledInner is now propperly preserved
- guessed traffic light programs no longer contain duplicate consecutive phases
- Fixed bug where option ramps.guess would sometimes fail to add necessary lanes.
- Extremely short internal lanes are no longer split. Instead a warning is issued since these cases usually indicate an invalid junction geometry.
- removed option --all-end-follower as it's not longer needed and buggy
- when using tazs (districts) they are now correctly attached to the network with an edge with travel time 0 (before it was 1)
- subscriptions for VAR_LOADED_VEHICLES_IDS now work
- when setting lane change mode to prevent all changes due to a certain change-motivation, motivations with lower priority are now correctly considered.
- adding a vehicle with a negative depart position gives an error message (applies only to ADD not to ADD_FULL)
- adding a vehicle with a depart time in the past gives an error instead of silently dropping the vehicle
- vaporizing parked vehicles is now possible #1166
- forcing a lane change for a stopped vehicle now correctly removes the current stop from the list of pending stops
- Fixed bug where sortRoutes.py would produce invalid XML (thanks to Pieter Loof for the patch)
- Fixed bug in traceExporter.py when generating files for NS2 which caused non-sequential IDs to be written.
- Fixed several divisions by zero and integer over- and underflows reported by the clang sanitizer
- Trying to open existing files which do not have reading permissions now gives a correct error message
- All tools now give error messages when an output socket is not any longer available on closing
- Added improved capabilities for pedestrian simulation
- Added option --pedestrian.model <STRING> with available values nonInteracting and striping. The most important features of the striping model (which is the new default are:
- Pedestrian cross streets and interact with traffic (blocking vehicles, blocked by vehicles, reacting to traffic lights)
- Pedestrians interact with each other (jam)
- Pedestrians select their route dynamically to avoid red lights when multiple paths across an intersection are available.
- Added options --pedestrian.striping.stripe-width <FLOAT> and --pedestrian.striping.dawdling <FLOAT> to configure the 'striping'-model
- Added option --lanechange.overtake-right <BOOL> to switch between german overtaking laws (default) where overtaking on the right on highways is prohibited and american overtaking laws
- Vehicles which are already on a junction but have to wait for another vehicles (also on the junction) now always drive up to point where their path crosses with the blocking vehicle.
- Added option --random-depart-offset <TIME> to randomize departure times for all vehicles by applying a positive (uniform) random offset.
flowelements now support attribute
probabilityfor specifying flows with randomly distributed departures (following a binomial distribution). Each second a vehicle is inserted with the given probability (which is scaled according to the given --step-length).
- Vehicles with a
vTypewhich has a specified
vClasswill now get appropriate default values for some of their parameters (i.e. busses will be longer than 5m by default). Refer to Vehicle_Type_Parameter_Defaults for details.
- the option --scale <FLOAT> can now also handle values > 1 and inserts more vehicles in this case
- added HBEFA3 emission model
- added outputs conforming to the Amitran standards
- Added improved capabilities for pedestrian simulation
- the option --no-warnings <BOOL> now also applies to the GUI message window
- Added person coloring scheme by selection and by angle
- All person modes now give a waitingTime
- Person parameter dialog now inclues attributes 'edge', 'position', 'angle' and 'waitingTime'
- Pedestrian crossings are now indicated by the typical zebra-pattern (light color indicates that pedestrians have priority, dark color means that vehicles have priority)
- Showing permission code in lane parameter dialog, updated style color by permissions
- Uncontrolled links (not part of a junction logic) are now shown with index -1
- Now showing edge type in lane parameter dialog
- Customizable drawing of ids for edges of type crossings and walkingarea
- Added lane coloring scheme by angle
- Lanes are now drawn with smooth shapes regardless of geometry (fixed white gaps at corners)
- Added element
<crossing>for '.con.xml' files. This can be used to specify pedestrian crossings
- Added attribute
<type>elements in .typ.xml files. If this is given, edges of this type will get an extra lane with
allow="pedestrian"and the specified width.
- Added options --sidewalks.guess <BOOL>, --sidewalks.guess.min-speed <FLOAT> and --sidewalks.guess.max-speed <FLOAT> to trigger guessing of sidewalks
- Added option --crossings.guess <BOOL> to trigger guessing of pedestrian crossings
- Added options --tls.guess-signals <BOOL> and --tls.guess-signals.dist <FLOAT> to interpret special traffic light nodes which surround an intersection as the signal positions for that intersection. This heuristic is useful for correctly importing a typical representation of traffic lights in OSM data.
- Added attribute
<node>elements in .nod.xml files. This allows to specify a custom shape for that node.
- can write networks in the Amitran format
- Added element
<flow>elements now support attribute
viafor specifying intermediate edges to use during routing.
routedefinitions can now be given in additional-files just like for sumo
- Pedestrian walks with attributes
toare now routed and written with attribute
- the maximum (the average) speed factor are taken into account when calculating the minimum (the default) travel times
- References to an unknown
vTypeare now an error (which can be ignored with --ignore-errors). Previously, an unknown
vTypewas silently copied to the output and treated like the default type during routing.
- OSM road shapes and traffic light positions can now be exported by setting the appropriate entries in the typemap file.
- reads now OD matrices in Amitran format
- Added randomTrips.py option --pedestrians <BOOL> to generate pedestrian walks
- Added randomTrips.py option --max-distance <FLOAT> to limit the straight-line distance of generated trips
- Added randomTrips.py option -a, --additional-files <FILE>[,<FILE>]* which is passed to duarouter
- Added randomTrips.py option -i, --intermediate <INT> for generating trips with intermediate waypoints
- Added randomTrips.py option --maxtries <INT> to control the number of attemps for finding a trip which meet the given distance constraints
- convert almost arbitrary XML outputs (with a given schema) to CSV and protobuf, see Tools/Xml
- Removed obsoleted --incremental-dua-step and --incremental-dua-base option (use --scale instead)
- An explanation for vehicle insertion can be found here.
- Default parameters for different vehicle classes.
- Documentation for Calibrators. These simulation objects allow for dynamic adaption to traffic flow and speed at selected edges.
- The obsolete Media Wiki, Trac and Wordpress instances at the SourceForge Hosted apps facility have been removed altogether
vClassdefinitions where added and others renamed. Old definitions will continue to work but some will cause deprecation warnings.
- Referenze typemap files for importing edges and polygon data from OSM networks as well as from other formats can now be found at <SUMO_HOME>/data
- SUMO builds now with clang as well
- The shortcut -p for the option --print-options was removed because of possible name clashes
