Fixed building under gcc4.7; thanks to Karsten Roscher
Simulation
Fixed the bug which prevented vehicles to be inserted in the
middle of a street using departPos="free" (ticket732,
thanks to Björn Hendriks for reporting it)
Fixed several bugs that were causing collisions
Fixed bug in the default car-following model wich lead to
larger-that-necessary following distances. The maximum possible
flow is now greatly increased.
Fixed bug where simulation would not terminate if vehicles with
fixed depart speeds could not be inserted
Fixed bug that lead to unnecessarily low departure speeds under
some conditions
Fixed bug which sometimes caused vehicles to use the wrong lanes
sumo-gui
Fixed loading of breakpoints, reported by Anderson Rocha,
thanks!
netconvert
reading tls offset from VISUM files corrected
OSM-ids are now read as long longs (long long int under
Linux)
added the option --tls.discard-loaded<BOOL> which avoids loading traffic lights from other
formats than XML (in XML, one can simply replace the type
"traffic_light" by "priority"); removed option --osm.discard-tls<BOOL> which did the
same for OSM-networks only
SUMO-networks with tls offset now load correctly
connections for highway ramps no longer cross incorrectly
OpenDRIVE-export: corrected lane offsets (geometry) and lane
linkage (topology)
connections which can not be set when being loaded are kept and
retried after network changes, such as ramps building, or nodes
joining
now correctly setting edge priorities when importing dlr-navteq
networks
junctions with incoming edges of differing priority can no
longer have type 'right_before_left'
OSM-imported railways are now correctly imported as one-way
which avoids lots of bogus rail edges
OSM-imported railways no longer yield to regular roads
OSM-imported railways now have proper default speeds
changing attributes from or to of an existing edge no longer
crashes
improved heuristic for detecting roundabouts. Now recognizes
roundabouts with divided attachment edges.
fixed bug where import would fail due to tag elements with
empty v-attribute
fixed bug where the special connection attribute pass was lost
when writing plain xml or importing sumo networks (this
attribute affects the junctionLogic in built networks and
declares that a connection never yields).
fixed bug that caused right-of-way computations to fail
(resulting in collision) at turnaround lanes
fixed bug that caused connections to be considered foes even if
they did not conflict. The resulting network inconsistency
manifested in collisions.
NETGEN
Options --offset.x and --offset.y are no longer ignored
added configure option --enable-profiling to be used with gprof
Simulation
added the option --routing-algorithm<STRING> to configure simulation routing
(devices,triggers,traci). Allowed values are dijkstra,
(default) and astar
Rerouting via 'device.rerouting' is now much faster
variable speed signs now accept negative speed values. this
causes them to reset the edge back to its default speed
if any vehicles are vaporized
during simulation the attribute vaporized="NUMBER_OF_VAPORIZED_VEHICLES>
is added to the meanData output for the respective edge.
added the option --maxDist.routesize<INT> to limit the size of routeDistributions
(useful to conserve memory for long-running simulations)
added the option --fcd-output.geo. If this option is given the output from --fcd-output<FILE> will
contain geo coordinates instead of cartesian coordinates.
compact specification of routeDistribution (using attribute
routes) now recognizes attribute probabilities
added the option --vehroute-output.write-unfinished. If this option is given, vehicle routes for
all vehicles on the road will be written at the end of the
simulation.
added the option --device.rerouting.init-with-loaded-weights. If this option is given, weights supplied
with the existing option --weight-files<FILE> are used for initialiing the rerouting
devices.
Rerouter definition
destProbReroute now recognizes the special values
keepDestination and terminateRoute which causes a reroute to
the original destination or terminate the route respectively.
It is now possible to combine the
rerouter definitions
closingReroute and destProbReroute. In this case only
vehicles which are affected by the closingReroute sample a
new destination from the destProbReroute.
The verbose simulation summary now includes the number of
teleports
The vType attributes speedFactor and speedDev are now
officially supported and allow for a convenient way of
specifying vehicle speed distributions. Among other things these
can be used to model speeding vehicles which exceed given edge
speeds. More Details
TraCI
The deprecated "environment-related" commands were removed and
the documentation was finally corrected; position conversion
and distance computation
are still available via the Simulation Value Retrieval API.
Please note that the footprint has changed so that it matches
the other API calls.
Added python interface to convert cartesian to geo coordinates
and vice versa
sumo-gui
the gui can be started with multiple views by supplying a list
of files to option --gui-settings-file
street coloring by selection now colors all lanes for selected
edges (useful when loading selections from a file)
Visualizing rerouters with many trigger edges and many closed
edges no longer causes the GUI to slow down.
The lane-parameters dialog now list the street name as well as
the vehicle class permissions
Rail edges are now rendered with rails and crossties making them
stand out from normal roads.
Persons are now visualized during all steps of their plan and
allow accessing step information.
vehicles with guiShape="rail" are now visualized with multiple
carriages when the visualization option Show As is set to
simple-shapes. The overall length of the train and the number
of carriages is determined from the vehicle length
Vehicles can now be renderd with bitmaps using the new vType
attribute imgFile. This should be a grayscale image with alpha
channel to allow full recoloring functionality.
Persons can now be rendered with bitmaps when specifying a vType
with attribute imgFile just like vehicles (persons bitmaps
will not be rotated, however).
POIs can now be rendered with bitmaps using the new attributes
imgFile, width and height
the default vehicle coloring respects now colors assigned to the
vehicle, type or route (in that order) before assigning the
default color
the default color can be changed for coloring by vehicle / type
/ route
The vehicle parameter dialog now includes the vehicle specific
speed factor if speed distributions are used.
dfrouter
the speed column in flow input files is now optional
TOOLS
added options for generating random trips which help to increase
the quality of generated trips. see
Tools/Trip#randomTrips.py
improved the method parse in sumolib.output. It now supports
memory-efficient parsing of nested xml elements into convenient
python objects based on pulldom traversal
added several utility classes in sumolib.miscutils
added option --big to script route/sort_routes.py which allows
handling very large files at the price of increased hdd-reading
added script assign/duaIterate_analysis.py for plotting
statistics of a duaIterate run
added script route/route2poly.py for visualizing routes with
polygons in the sumo-gui
Documentation
Added schema definition for jtrrouter's
turns and sink definition files
reworked some of the XML parsing code, watch out for new parsing
errors or ignored attributes
added --xml-validation to all executables which enables Xerces-C schema
validation for input files having a schema defined
netconvert
replaced the option --plain.keep-edge-shape with the inverted option --plain.extend-edge-shape. The new default
is to keep given edge shapes and only extend them if this option
is set. Extending edge shapes inadvertently can lead to invalid
connections and priorities.
