Fixed crash when using calibrators with discontinuous intervals
instantInductionLoops no longer miscount vehicles which change
lanes on the detector edge.
instantInductionLoops now write events in the correct order
instantInductionLoops now properly register vehicles staying on
the detector
fixed invalid speeds when running with step-length < 1 (see #1024)
the departSpeed value of a vehicle can now be as high as
laneSpeed * speedFactor
fixed error in a car-following related formula which was causing
collisions (see #1026)
queue-output now correctly measures the length from the start of
the queue to the rear of the last standing vehicle and no longer
includes one additional minGap
when using speedDev and
departSpeed, the distribution will
be adapted so that a vehicle can use the specified speed.
The attribute emitted of the
summary output was
renamed to inserted
fixed bug which caused vehicles to brake without good reason
(see #1052)
flow on a highway will no longer come to standstill just to let
vehicles from an on-ramp merge.
vehicles now manage to change to the necessary lanes much more
often and thus avoid having to stop and block upstream traffic.
vehicles now use all lanes of a multi-lane roundabout instead of
only the outer lane.
fixed tripinfo output for teleporting vehicles
(#990)
fixed handling of stops before starting position
(#1056)
fixed state loading with vehicle type distributions
(#1080)
fixed memory leak of route distributions together with route
probes
(#1077)
fixed reference counts for routes in state save
sumo-gui
Right-click now always resolves to the correct object again. The
problem was introduced in 0.18.0 and was triggered by drawing
railways
The object locator no longer jumps to an arbitrary location if
the requested object is not found
TraCI
TraCI now returns the "netto" occupancy (without minGap) as
other outputs do (was #932)
Traffic light program changes via TraCI now takes effect
immediately instead of one step later. (Thanks to Christoph
Sommer for reporting and fixing this problem)
TraCI respects now the begin time option of a simulation
(#1049)
duarouter
fixed crash when repairing routes with intermediate dead-end
edges
fixed generation of route distributions with 0 probability for
trips where the starting and ending edge were connected
netconvert
fixed bug where roundabouts sometimes had incorrect right-of-way
rules
option --keep-edges.in-geo-boundary now works when giving a .net.xml file as input
OSM import no longer fails for non-standard input data (i.e.
empty key attribute or non-numerical value for tracks
attribute)
option --junctions.join no longer causes edges with a length above --junctions.join-dist<FLOAT> to be
removed.
Increased Simulation performance when handling lots of traffic
lights (rewrote code which was updating traffic lights more
often than necessary)
added vType-attribute
laneChangeModel for customizing the
lane changing behavior. Allowed values are DK2008 (the model
used until version 0.18.0), JE2013 and LC2013 (the new
default model).
Vehicles moving across junctions now consider the exact crossing
points at which their paths intersect with other vehicles when
deciding on their speed. This leads to smoother traffic flow
across junctions.
Vehicles may now change lanes while driving across junctions if
the edge they were coming from has priority (only on networks
with merged internal lanes, see netconvert changes). This
improves simulation performance, particularly on multi-lane
roundabouts.
Teleport warnings now always include a reason. For a vehicle
that is teleported because its waitingTime exceeds
time-to-teleport the reason can be:
wrong lane when the vehicle was stuck on a lane which
did not allow it to continue its route,
yield when the vehicle was stuck on an unprioritized
road and did not find a gap in traffic or
jam when the vehicle could not continue because there
was no space on the next lane
conflicts between speed deviation and departure speed are
handled more gracefully (#1035)
sumo-gui
now drawing blinkers to visualize a vehicles desire to change
lanes (this is only noticeable if a vehicle cannot change lanes
immediately).
added vehicle coloring modes by offset from best lane and by
acceleration
when drawing a vehicles route, the lanes which the vehicle
intends to use are highlighted where this is known (previously
the rightmost lane was always used).
Added hotkeys Ctrl + A, Ctrl + S, Ctrl + D for running, stopping and
stepping the simulation
Added a menu for opening the object locator dialogs. Using the
menu hotkeys allows searching for simulation objects without
using the mouse.
The vehicle parameter dialog now also contains information
related to the vehicle type.
TraCI
lane change requests now have a higher priority by default and
will thus succeed much more frequently.
added new command lane change mode (0xb6) to control
conflict resolution between TraCI-lane-changing request and
lane-changing decisions by the laneChangeModel. It also allows
to override safety constraints and to trigger cooperative speed
adjustments to better fulfill change requests.
The python API throws now a TraCIException on recoverable errors
(such as an unknown vehicle id) and brings the system in a
consistent state
(#1043)
added possibility to remove waiting cars inspired by Bob Holcomb (#942)
improved execution speed of context subscriptions
netedit
added option for reversing the direction of edges
lanes can now be selected based on their index
netconvert
when specifying connections it is now possible to refer to edges
which got split (#492)
added new projection option to convert Gauss-Krueger to UTM
duarouter
major refactoring of input parsing, it is now possible to mix
trips, flows and vehicles in one file
reworked type-related warnings when importing OSM data to
increase readability
modified naming conventions for internal lanes: previously every
internal lane had its own internal edge. The id of this internal
edge was ":<junction_id><link_index>" and the id of the
internal lane was ":<junction_id><link_index>0".
Now Internal lanes with the same start and end edge have a common
internal edge (except for lanes following an internal junction).
The id of this internal edge is
":<junction_id><link_index_of_first_lane>" and the id of the
internal lanes is ":<junction_id><link_index><lane_index>".
The following relation still holds between link indices of
internal lanes and their ids: <interal_edge_id> +
<internal_lane_id> == <link_index>. The change was done to allow
lane changing on internal lanes. As a side effect of merging
internal lanes into a single edge, lane lengths may differ
compared to the previous release. This is because the simulation
length of a lane is always the average of the geometrical length
of all lanes of an edge.
TraCI
The documentation for vehicle value
retrieval/modification
now includes information on setting/retrieving vehicle-type
related values for individual vehicles (i.e. length, maxSpeed).
removed obsolete vehicle add command
TraCI version is now 7
reworked checks for gdal and fox in configure
documentation now contains links to the wiki pages it was generated from
added option --link-output<FILE> for recording the approach of vehicles at
junctions. This option addresses the need of developers when
investigating junction control.
added new abstract vehicle classes "custom1" and "custom2" for
user defined purposes.
drivers on a minor road now grow impatient while waiting for a
gap in the traffic. After a while they will drive even if it
means that another car has to slow down to accommodate them (as
before, they will only drive if it is safe to do so).
added vType attribute impatience which affects the
willingness of drivers to cut into traffic even if it forces
other drives to brake.
added option --fcd-output.signals<BOOL> for including a vehicles signal state in the
output (brake lights etc.)
implemented "expected" attribute for stops, which expects IDs of
people that have to enter the vehicle to allow the vehicle to
leave the stop. Should be used with "triggered='true'" (would
not work otherwise). Thanks to Shubham Jain for pointing out the
wrong description of the possibilities in
[1].
added options for saving and loading simulation states.
Simulation states can be saved at predetermined times and then loaded to initialize a new
simulation (this also requires loading the network and routes of the
original simulation). When the filename for saving ends with .sbx
the file will be saved in a binary format instead of xml.
option --sloppy-insert<BOOL> is marked deprecated because the behavior is now the
default, use --eager-insert<BOOL> to get the old behavior
vehicle route output for persons now includes complete plans
sumo-gui
it is now possible to toggle the simulation time display between
'seconds' and 'hour-minute-seconds' by clicking on the
'Time'-button next to the time display. The state of this
setting persists across GUI sessions.
it is now possible to toggle between alternate delay values by
clicking on the 'Delay'-button next to the delay dial. Clicking
causes the current delay value to be saved as the alternative
value. The alternative delay value persists across GUI sessions.
parking vehicles are now being drawn (at the side of the road)
the vehicle parameter table now contains information about the
status of stopped vehicles
vehicles can now be colored by their selection state
added option for selecting a vehicles foes at the next junction
to the vehicle popup menu (useful when coloring by selecting)
brake lights will no longer be triggered when the route ends
unless the vehicle actually has to slow down.
now providing separate options for customizing the visualization
of persons
netconvert
when using the option --no-internal-links the edge lengths are now increased to
compensate for the missing internal links. Thus, route lengths
will correspond better to physical distances and roundabouts are
less prone to congestions.
added option --keep-edges.in-geo-boundary which works similar to option --keep-edges.in-boundary but uses geodetic
coordinates instead of cartesian.
added new node type priority_stop. This works similar to type
priority but minor links now require a stop
added option --ignore-errors.edge-type for ignoring unknown edge types during loading.
This happens frequently when dealing with plain xml files based
on OSM data.
now parsing the OSM-Attribute "tracks" to determine whether a
railway element is unidirectional or bidirectional.
added option --osm.railway.oneway-default<BOOL> for setting the default behavior when importing
railways without "tracks" attribute. The appropriate value
depends on the mapping style of the regional OSM community.
added option --geometry.max-angle<FLOAT> which warns about sharp turns on an edge. This is
enabled by default for turns above 99 Degrees.
added option --geometry.min-radius<FLOAT> which warns about sharp turns at the start and end
of an edge. This is enabled by default for radii below 9 meters
added option --geometry.min-radius.fix<BOOL> which prunes geometry to avoid sharp turns at the
start and end of an edge. This is disabled by default.
added option --check-lane-foes.all<BOOL> (default=false) for lifting junction restrictions
for vehicles which exit on different lanes of the same edge
without crossing paths. This improves junction throughput in
many cases but is a more aggressive interpretation of german
traffic laws.
added option --check-lane-foes.roundabout<BOOL> (default=true) for lifting some junction
restrictions at roundabouts. This conforms to the typical layout
of roundabouts where restrictions on lane-changing allow such
movements.
TraCI
added optional flags for cmd stop (0x12) to set the parking and
triggered status
added command stop state (id 0xb5) for retrieving the
stopped,parking and triggered status
added command resume (0x19) for resuming from the current stop
reduced verbosity on connection close (no more good byes)
The elements <vehicle>, <flow> and <vType> now
support child elements of the form <param key="myKey"
value="myValue/>. These can be used when implementing custom
functionality (see
Developer/How_To/Device).
code for messaging functionality removed (was disabled by
default anyway)
tripinfos now contain the correct arrivalPos and routeLength
values
(#814)
fixed collision bug for simulations that were running with
option --no-internal-links
fixed bug that caused vehicles to sometimes use the wrong lane
and occasionally lead to collisions
(#586,
#836)
fixed bug in the default car-following model which lead to
collisions when using vehicle types with different deceleration
values
fixed crash when specifying an invalid car-following model in
the input files
fixed invalid vehicle insertions under special conditions
increased junction throughput (fixed bugs related to
right-of-way timing computation)
fixed bug where vehicles drove faster than allowed at arrival
and when changing from fast to slow lanes
simulation routing with taz now works in the presence of vClass
restrictions.
fixed bug where vehicles sometimes did not follow the
arrivalLane attribute.
fixed bug where entryExitDetectors issued invalid warnings about
vehicles leaving without entering
fixed bug where inductionLoops and instantInductionLoops
sometimes failed to detect vehicles
sumo-gui
fixed occasional crash when additional vehicle visualizations
are active
fixed bug where the simulation control buttons (start,step)
sometimes remained gray when tracking a vehicle
netconvert
fixed bug that caused right-of-way computations to fail
(resulting in collision) at left-turning connections
fixed bug where networks imported from
OpenStreetMap had
incorrect lane numbers when forward and backward directions
differed in lane count.
fixed bug where some sets of junctions where erroneously
classified as roundabouts when using option --roundabouts.guess resulting in
invalid junction logics and causing collisions during simulation
fixed bug where inconsistent (unloadable) networks where created
using option --ramps.guess
deleted nodes are no longer included in the final network
boundary
polyconvert
Removed dependency on key/value ordering when importing from
OSM. Instead, now elements which match multiple typemap entries
are exported multiple times.
fixed projection errors when importing polygons for very large
networks.
ROUTER
Fixed bug where output files contained wrong values for the
emissionClass attribute (i.e routers did not properly copy the
the value from input to output files). This sometimes caused
duaIterate.py to fail.
major refactoring, now handling route, trip and flow inputs with
one handler (can be mixed in one file)
persons and stops in route input files no longer disappear
flow handling is similar to simulation (ids generated with "."
separator)
TraCI
Fixed handling of the parameter to the simulationStep command
(CMD_SIMSTEP2). Formerly a single simulation step was performed
if the given target time was lower than the current simulation
step. Now the simulationStep command is ignored in this case.
The proper use case for this command is to run the simulation
up to the given target time. Some scripts (including tutorial
scripts) wrongly passed the step duration as argument and only
worked because of this bug. To make these scripts work it is
sufficient to omit the parameter altogether.
added support for microscopic calibrators. These trigger-type
objects can be used to increase or reduce traffic volume and to
regulate speeds at selected edges. Using calibrators it becomes
possible to calibrate a simulation according to known traffic
measurements (i.e. from real-life induction loops) without using
TraCI. For usage examples see the test suite at
tests/sumo/extended/calibrator.
renamed XML root elements of the netstate (raw dump) and the
mean data outputs.
added a car following model which respects slope (kraussPS),
your network needs z-coordinates then
sumo-gui
added optional POI attributes 'lon' and 'lat' for specifying
position in geo-referenced networks.
added options for showing polygon names and changing their line
width
gui-setting files now support the element <breakpoints-file value="mybreakpoints.txt"/> for loading
breakpoints at the start of the simulation
new color representation as four unsigned bytes including an
alpha channel (transparency) all in the range of 0-255
human readable color representations for red, green, blue, cyan,
magenta, yellow, black, white, and grey
in plain connection files the element delete now also works
when the connection doesn't exist yet (i.e. when building a
network from plain nodes and edges and the connection file only
contains delete elements).
now importing most turning restrictions from
OpenStreetMap
when importing SUMO networks without internal link the output
network will be built without internal links by default.
now warning about networks with large absolute coordinates since
these will cause visual errors in guisim
added option --tls.discard-simple which discards traffic lights at geometry-like
junctions (no intersecting streams) loaded from formats other
than plain-XML. This is particularly useful when importing
networks from OpenStreetMap which contain many pedestrian
actuated traffic-lights.
