Vehicles with departspeed="max" now properly adapt their speed to vehicles ahead
at insertion. This results in higher flows.
Teleporting vehicles will only be inserted if they fit fully
onto the destination lane.
Fixed some inconsistencies in E3-Detector output (see E3 Further_Notes).
Flows using attribute probability now correctly terminate when attribute end is given.
Fixed several bugs for traffic lights of type actuated.
Pedestrians using the model striping now always respect attribute arrivalPos
Fixed crash when computing pedestrians positions on short
walkingAreas.
Fixed crash when using car following model <carFollowing-IDM/>
Fixed bug that was causing collisions at intersections.
Fixed bug that was causing collisions due to unsafe
lane-changing decisions.
Fixed bug that was causing collisions due to unsafe insertion.
Fixed bug that was causing collisions due to unsafe re-insertion
after teleporting.
Fixed bug that was causing silent collisions between vehicles
on different edges. Previously this type of collision was not
reported but visible in the gui.
Fixed bug that sometimes lead to inferior lane-change decisions
in networks with vehicle class restrictions.
Fixed bugs that sometimes prevented vehicles from being inserted
at the earliest opportunity.
Fixed bug that prevented vehicles from being inserted when their departSpeed was close to their maximumSpeed and using car following model <carFollowing-IDM/>.
Fixed bug that was causing unnecessary lane changes leading to
oscillations.
Fixed bug that was degrading the cooperation between vehicles
during lane changing.
Flows now always insert at least 1 vehicle for any positive
repetition period (if the simulation time reaches the begin-time).
Fixed position caching which caused wrong positions and angles
after lane changes #143
Fixed the usage of different random number generators for route
file parsing and vehicle movement
Fixed rerouting close to junctions
sumo-gui
Single-stepping the simulation with hotkey (Ctrl-D) is now
working as smoothly as intended.
Changing simulation delay via mousewheel now works when the
pointer is on top of the dial.
Vehicle coloring by acceleration, by time gap and by offset
from best lane now correctly visualize negative values
Persons which are waiting or riding in a a vehicle now face the
correct direction.
Fixed crash related to parking vehicles.
Corrected angle of parking vehicles.
Fixed bug where train carriages were drawn incorrectly.
The drawing size of laneAreaDetectors can now be scaled
properly.
netconvert
Street-sign-output now references the correct xsd file.
warnings are emitted if no proj support is available and
projection is needed
duarouter
Fixed crash when using options --repair and --ignore-errors.
Fixed crash when using option --remove-loops.
When using option --remove-loops the non-looping parts of the route are now
kept unchanged as intended.
Progress indicator is now only shown if the --end option is used.
Fixed crash when loading <flow> with attribute probability.
TraCI
Fixed crash when retrieving vehicle variable best lanes (id
0xb2) while the vehicle is on an internal lane.
The command induction loop value (last step vehicle data Command_0x17))
now returns the value -1 for the leaveTime of a vehicle
which has not yet left the detector (instead of returning the
current time step as before).
Whenever rerouting vehicles, a new route is only recorded when
it differs from the previous route.
tripinfo-output now includes attribute timeLoss which holds the time
loss compared to the maximum driving speed.
Added option --tripinfo-output.write-unfinished<BOOL>. When this is set, tripinfo output will
additionally be written for all vehicles that did not arrive at
the end of the simulation.
Vehicles with the attribute departLane="free" now consider the free space on all
candidate lanes instead of the number of vehicles. This results
in higher flow.
Added a new departLane-value named departLane="first" where vehicles are inserted
on the rightmost lane they are allowed to use; this is the new
default insertion lane
Now supports parallel routing by using the option --device.rerouting.threads<INT>
Added new routing algorithms 'astar' and 'CH' which are faster
than the default 'dijkstra' algorithm.
flow elements with attributes from and to can now be loaded directly in the
simulation and will automatically be routed according to the
current traveltimes at begin.
Invalid stops now generate better error messages, see #1458
Added option --vehroute-output.intended-depart<BOOL>. This allows to generate vehicle route files which
reproduce the original behavior when using one shot routing. #1429
Added option --weights.random-factor<FLOAT> to disturb edge weights when routing in the
simulation. This allows modelling imperfect information, helps
to avoid biases when multiple routes have the same length (i.e.
in grid networks) and may be used to prevent jams on a single
shortest path.
sumo-gui
Now appending .xml suffix when saving viewport, view settings
or decals
Added lane coloring by loaded weights. This colors by whatever
attribute was set with option --weight-attribute<STRING>. The weight value is also shown
in the parameter dialog.
Added lane coloring by priority. This uses the edge priorities
used during network creation. The priority value is also shown
in the parameter dialog.
Added junction coloring by type.
Added visualization options for drawing vehicles, persons, POIs,
polygons and additional gui objects with constant size when
zooming out.
The dialog for changing visualization settings is now resizable
and will remember its size across application runs. All settings
are now scrollable to allow work on smaller screens.
The attributes which can be used to customize lane colors can
now also be used to scale their width. This is done in the view
customization dialog unter 'Streets' -> 'Scale width'. See
[1].
Vehicle coloring by time since lane change now indicates the
direction of the change by its color
Added new link state 'u' to encode red-yellow phase (shown as
orange). Vehicles behave as if 'r' (red) was set. This linkstate
may be used to indicates upcoming green phase according to
RiLSA.
Lane coloring by speed now uses more colors (the same as vehicle
coloring by speed).
netconvert
Roundabouts can now be specified via plain-xml input.
They are also written to the .edg.xml-file when using option --plain-output-prefix.
duarouter
Now supports parallel routing by using the option --routing-threads<INT>
Added new routing algorithms 'astar' and 'CH' which are faster
than the default 'dijkstra' algorithm.
jtrrouter
Routes which loop back on themselves are no longer generated by
default (can be enabled using option --allow-loops).
TraCI
added method vehicle.setSpeedMode() to the python API
(Command 0x3b).
added method areal.getLastVehicleIDs() to the python API
(Command_0x12).
added argument extended to method lane.getLinks() in the
python API (default False). If it is set to True, the method
returns all the information defined for
(Command_0x33)
instead of a subset.
Tools
Added randomTrips.py
option --weights-output-prefix<STRING> to generate weight files which can be used to visualize
the edge probabilities for being source/destination/via in
sumo-gui.
Added randomTrips.py
option --weights-prefix<STRING> which allows loading edge probabilities for being
source/destination/via. The file format is the same as for
option --weights-output-prefix<STRING> with missing edges defaulting to probability 0 and
missing files defaulting to normal randomization.
Added dua-iterate.py
option --zip to zip old iteration outputs using 7-zip
Added script server.py
for "three-click" scenario generation (thanks to Jakob
Stigloher)
