od2trips:
Can now specify persontrip modes with option --persontrip.modes. Issue #7219
meso:
Added option --meso-tls-flow-penalty FLOAT. This can be used to control the headway penalty to model maximum (averaged) flow at traffic lights. Formerly the option --meso-tls-penalty was responsible for this but now the latter option only controls the travel time penalty. Issue #7497, #7491
All Applications:
Symbolic color definition "random" can now be used (i.e. in vehicle, vType, poi, ...). Issue #7058
There is a new emission model "Zero" replacing "HBEFA*/zero" etc. Furthermore the default emission class for a model can now be chosen using something like "HBEFA3/default". Issue #7098

Added functionality for retrieving lane, position and stopped vehicles for traci domains 'busstop', 'parkingarea', 'chargingstation' and 'overheadwire'. Issue #5952, #7099
The python client now supports the optional argument 'traceFile' in function traci.start which records all traci commands to the given file (also works for libsumo.start). The optional boolean argument 'traceGetters' can be used to switch off tracing of data retrieval functions. Issue#6604, #7481
Added function 'vehicle.replaceStop' which replaces the upcoming stop with the given index and automatically adapts the route to the new stop edge. Issue #7226
Added function 'vehicle.getFollower' which works like getLeader but looks backwards. Issue #7107
Retrieval of prior person stages now includes departure time and travel time. Issue #7274
Added 'simulation.getVersion' to libsumo and C++ client. Issue #7282

Improved cutRoutes.py for use with person plans. Issue #6027, #7384
Added new tool addStopDelay.py to add random stop delays to a route file. Issue #5209
routeSampler.py: Now supports option --weighted. This causes routes to be sampled according to their probability. The probabilty can either be specified explicitly using route attribute 'probability' or implicitly if the same sequence of edges appears multiple times in the the route input. Issue #7501
Other:
Simulation:
Route attribute 'period' was renamed to 'cycleTime'. Issue #7168
Total simulation running time is now in seconds rather than milliseconds. Issue #7255
netconvert
Roads of type 'highway.track' (aggricultural roads) are no longer accessible by cars when importing OSM data. Issue #7082
Netedit:
Demand creation entries have been renamed to better distinguish the different variants (i.e. flow with embedded route or flow with origin and destination). Issue #7175
TraCI:
In the python client, function vehicle.getLeader can now optionally return the pair ("", -1) instead of 'None' if no leader is found. The new behavior can be enabled by calling function traci.setLegacyGetLeader(False). In later versions this will be the default behavior. The return value 'None' is deprecated. Issue #7013
The function 'libsumo.vehicle.getNextStops' now returns a list of StopData objects rather than a list of tuples (the same result type returned by getStops) but different from the return type of 'traci.vehicle.getNextStops'. If the python script should be fully compatible between traci and libsumo, the new function 'vehicle.getStops' must be used.
Tools:
randomTrips.py now generates repeatable results by default (by using a fixed default seed). To obtain the prior random behavior without specifying a seed, the option --random can be used (just like for sumo). Issue #6989

routeSampler.py: fixed bias in departure time for the generated vehicles. Issue #6786
Enhancements:
Simulation:
Taxi device now supports ride sharing. Issue #6544
Added option --extrapolate-departpos. When this option is set, vehicles with a departure time that lies between simulation steps have their depart position shifted forward to better reflect their position at the actual insertion time. This can greatly reduce depart delay and increase and insertion flow in high-flow situations. Issue #4277
Traffic lights of type 'actuated' and 'delay_based' now support the use of custom detectors. Issue #5125, Issue #6773
The new route attribute period is now applied repeatedly when rerouting the vehicle and the new route contains stops with attribute until to shift those times forward (e.g. on cyclical rerouters for public transport vehicles). Issue #6550

Added new 'device.toc' parameters 'mrmSafeSpot' and 'mrmSafeSpotDuration' to control the behavior during minimum-risk maneuvers. Issue #6157
Added option --vehroute-output.stop-edges to record the edges that were driven ahead of stop as part of the vehroute output. Issue #6815
Added option --weights.priority-factor FLOAT to factor the priority of edges into the routing decision with a configurable weight (edges with higher priority are preferred increasingly when setting this to a higher value). An application for this is railway routing. Issue #6812
Added option --device.rerouting.bike-speed to compute aggregated speeds for bicycles separately. Issue #6829
Automatic train rerouting by rail signal logic can now be disabled by setting option --device.rerouting.railsignal false as well as by vehicle and vType parameters (key="device.rerouting.railsignal"). Issue #6781
Trains can now be joined in reverse order (rear part id is kept). Issue #6803
Element <busStop> now supports attribute 'parkingLength'. This can be used define the available space for stopping vehicles with parking="true" independent of the length of the busStop along the lane. Issue #3936

sumo-gui
Missing data values (color by edgeData) can now be distinguished from negative data values. Issue #6660
<edgeRelation>-data files can now be visualized. Issue #6659
Traffic lights of type 'delay_based' can now dynamically toggle detector visualization.
Train reversals are now indicated when ''Show Route'' is active. Issue #6744
Vehicles can now be colored by 'by stop delay'. This computes the estimated departure delay at the next <stop> with an 'until' attribute. Issue #6821
Travelled distance (odometer) is now listed in the vehicle parameter dialog.
Junction name is now listed in the junction parameter dialog and can optionally by drawn in the view. Issue #6635
Lanes that explicitly allow rail and passenger traffic are now highlighted with a distinct color in the default color scheme. Issue #6844
When loading a network with internal lanes and setting the option --no-internal-links, the internal lanes are still shown. This helps to understand track topology in rail networks. Issue #6852
Visualization of a vehicles route can now be configured with the menu option 'Draw looped routes' which can be disabled to reduce clutter in looped public transport routes. Issue #6917
netconvert:
Edge attribute spreadType now supports value roadCenter which aligns edges with common geometry so that the geometry reflects the middle of the road regardless of differences in lane numbers (causing natural alignment for turning lanes). Issue #1758
Added option --default.spreadtype to set the default spread type for edges. Issue #6662
Connections now support attribute ''length'' to customize the length of internal lanes. Issue #6733
Added option --default.connection-length to overwrite the length of internal lanes with a specific value. Issue #6733
Added option --railway.topology.direction-priority to assign edge priority values based on the preferred track usage direction (determined heuristically from uni-directional track).
Added node attribute 'name' to hold an optional string label. Issue #6635
Direction-specific speeds are now imported from OSM (maxspeed:forward, maxspeed:backward). Issue #6883
duarouter:
When loading weights from edgeData files, arbitrary attributes can now be used with option --weight-attribute. Issue #6817
Added option --weights.priority-factor FLOAT to factor the priority of edges into the routing decision with a configurable weight (edges with higher priority are preferred increasingly when setting this to a higher value). Issue #6812
TraCI:

Warnings are issued when the difference between road speed and connection speed rises above a configurable threshold (--junctions.limit-turn-speed.warn.straight, --junctions.limit-turn-speed.warn.turn). These warnings often indicate exaggerated road speeds on urban roads as well as faulty geometry. Issue #1141
Geo-reference information is now imported from OpenDRIVE input. Issue #4414
NETGENERATE:
Simplified node and edge names:
The alphanumerical junction naming scheme now supports arbitrary grid sizes (using ids like XY23)
The alphanumerical junction naming scheme also extends to spider networks
The alphanumerical junction naming scheme is active by default (the option for enabling the old scheme was renamed from grid.alphanumerical-ids to --alphanumerical-ids).
When using alphanumerical junction ids, the intermediate string to is omitted from edge names because the edge ID already allows unambiguous determination of its junctions without it
Added option --rand.random-lanenumber to randomize lane numbers in random networks between 1 and default.lanenumber
Added option --rand.random-priority to edge priorities in random networks between 1 and default.priority
Added option --rand.grid to place generated junctions on a regular grid

Added options --turn-lanes <INT> and --turn-lanes.length <FLOAT> to add left-turn lanes to generated networks. Issue #3892
DUAROUTER:
Intended departure times (attribute depart) and intended vehicle id (attribute intended) are now added to vehroute-output of public transport rides. Issue #3948
Stopping place names are now added as XML-comments in route-output of public transport rides. Issue #3952
POLYCONVERT:
Option --osm.use-name now also applies to POIs. Issue #4246
TraCI:
Libsumo can now be used in place of the TraCI client libraries to increase execution speed of TraCI-Simulations by directly linking against SUMO for all SWIG-supported languages. Graphical simulation with libsumo is not yet supported.
function vehicle.add now supports using the empty string ("") as a route id to insert the vehicle on an arbitrary valid edge. This makes it easier to remote-control vehicles using moveToXY without defining an initial route. Issue #3722
added functions simulation.getCollidingVehiclesNumber and simulation.getCollidingVehiclesIDList to track collisions. Issue #3099
added functions simulation.getEmergencyStoppingVehiclesNumber and simulation.getEmergencyStoppingVehiclesIDList to track emergency stops. Issue #4312
added function edge.getLaneNumber to retrieve the number of lanes of an edge. Issue #3630
added function vehicle.getAcceleration to retrieve the acceleration in the previous step. Issue #4112
TraCI now allows to update a vehicle's best lanes (vehicle.updateBestLanes). Issue #4146
added function gui.hasView to determine whether graphical capabilities exist. Issue #4014
function simulation.getMinExpectedNumber() now includes persons that are still active in the simulation. Issue #3707
added function traci.getLabel to the python client to help working with multiple connections.
When adding a vehicle with a disconnected 2-edge route, it will be treated like a <trip> and rerouted automatically. Issue #4307
added functions vehicle.getRoutingMode and vehicle.setRoutingMode. When setting routing mode to traci.constants.ROUTING_MODE_AGGREGATED, smoothed travel times are used instead of current travel times. Issue #3383
Tools:
added script plot_trajectories.py which allows plotting various combinations of time, distance, speed and acceleration for all trajectories in a given --fcd-output file.
added script averageRuns.py for running a scenario multiple times with different random seeds and computing trip statistics
webWizard now correctly builds regions with left-hand traffic Issue #3928
Additional options for generateTLSE3Detectors.py that make it suitable for generating various kind of junction related output. Issue #1622
createVehTypeDistributions.py now also allows to generate vehicle parameter distributions. Issue #4171
Added function simpla.createGap() Issue #4172
sumolib now supports lane.getWidth(). Issue #3842
OTHER:
Miscellaneous:
The space character ' ' is no longer allowed in xml option values when separating file names. Instead the comma ',' must be used. Files with space in their path are now supported. Issue #3817
Documentation:
Added documentation on joined traffic lights and defining signal groups.
Added documentation on the simple continous lane-change model.
Documented all supported routing algorithms.
Simulation:
<vTypeProbe> is now deprecated in favour of FCD-output filtering
<vaporizer> is now deprecated in favour of calibrators.
The default arrival position for person walks is now the middle of the destination edge. This reduces the assymetry from arriving in forward or backward direction. Issue #3843
tripinfo-output attribute waitSteps which counts the number of simulation steps in which the vehicle was below a threshold speed of 0.1m/s was replaced by attribute waitingTime which measures the same time in seconds. This gives results which are independent of the --step-length simulation parameter. Issue #3749
The default value for option --device.rerouting.pre-period was changed from 1 to 60 to speed up simulation. Issue #3865
The default speed deviation has been changed to 0.1. When defining a new <vType> with attribute vClass, this also influences the default speed deviation:
truck, trailer, coach, delivery: 0.05
tram, rail, rail_electric, rail_urban, emergency: 0
everything else 0.1
Note: The previous behavior can be restored by setting option --default.speeddev 0
SUMO-GUI:
Default color for persons is now 'blue' to better distinguish them from vehicles.
NETCONVERT:
There is no longer an offset of 0.1m between lanes. This means the total visual width of an edge is now the sum of all lane widths. This also fixes an inconsistency between visualization and simulation as the vehicles always ignored this offset anyway. Road markings are now drawn on top of the lanes rather than between them. This causes small visual gaps in old networks (fixable by calling netconvert -s old.net.xml -o new.net.xml). Issue #3972
The default value for option --default.junctions.radius was increased from 1.5 to 4 in order to improve realism of turning angles.
The default value for option --default.junctions.corner-detail was increased from 0 to 5 to improve the visual realism of larger intersections.
Option --ramps.guess is now enabled by default
Vehicle speed while turning at intersections is now limited via the new option default --limit-turn-speed 5.5. To obtain the old behavior, this value can be set to -1.
TraCI:
TraCI Version is now 18
Embeded python is now deprecated in favour of Libsumo.
TraCI now consistently represents time in seconds as a double precision floating point. This affects all client implementations. For convenience the affected python calls are listed below. Modifying your scripts should be necessary only for the methods enclosed in double quotes:
"traci.simulationStep"

traci.edge.getEffort
traci.edge.adaptTravelTime
traci.edge.setEffort
traci.person.add
traci.vehicle.getAdaptedTravelTime
traci.vehicle.getEffort
traci.vehicle.adaptTravelTime
traci.vehicle.setEffort
"traci.vehicle.slowDown"
"traci.vehicle.changeLane"
"traci.vehicle.setStop"
traci.simulation.getCurrentTime still returns ms as int but has been deprecated in favor of traci.simulation.getTime
traci.simulation.findRoute
traci.simulation.findIntermodalRoute
"traci.simulation.getDeltaT"
"traci.trafficlight.getNextSwitch"
"traci.trafficlight.getPhaseDuration"
traci.trafficlight.getCompleteRedYellowGreenDefinition
"traci.trafficlight.setPhaseDuration"
traci.trafficlight.setCompleteRedYellowGreenDefinition
The TraCI boundary type has been replaced by a position list of 2 positions
The TraCI float type has been removed
All protocol functions returning single bytes now return integers (lane.getLinkNumber, polygon.getFilled, vehicle.isRouteValid, vehicle.getStopState)
In the C++ client the function vehicle.getEdges was renamed to getRoute to be consistent with other clients
The order of error checks in the TraCI server changed so that unknown object errors show up before unknown variable / command errors
The TraCI boundary type has been replaced by a position list of 2 positions
The TraCI float type has been removed
All protocol functions returning single bytes now return integers (lane.getLinkNumber, polygon.getFilled, vehicle.isRouteValid, vehicle.getStopState)
In the C++ client the function vehicle.getEdges was renamed to getRoute to be consistent with other clients
The order of error checks in the TraCI server changed so that unknown object errors show up before unknown variable / command errors
The python client:
the function vehicle.add was replaced by the function addFull. The old "add" is still present and can be reactivated by monkey patching the module (traci.vehicle.add=traci.vehicle.addLegacy)
constants which were previously available in the single domains have moved to traci.constants
now returns tuples instead of lists for all getIDList and several other calls

Function edge.adaptTravelTime(begin=... end=...) is now working as expected with times in seconds. ticket2808
Tools:
netdiff.py now correctly handles changes to spreadType and other optional attributes. ticket2722
sumolib.net now returns consistent values for edge.getShape(): the center-line of all lanes. Previously, the raw edge shape used in netconvert was returned.

Added new output option --stop-output <FILE> for generating output on vehicle stops (for public transport, logistics, etc.)
Vehicles that are inserted with departPos="last" now depart at the end of the lane when there are no leader vehicles. This reduces the overall variance in depart positions. ticket2571
The --step-log-output now includes statistics on time spend in TraCI functions. ticket2698
When a vClass is specified for a vehicle type, this information is used to assign a default emissionClass from the HBEFA3 model (Before all vehicles had class "HBEFA2/P_7_7" by default, even bicycles). The default class for passenger vehicles is now "HBEFA3/PC_G_EU4".

added option --ramps.unset which works as an analogue to --ramps.set and prevents edges from being treated as on- or off-ramps. ticket1763
Now importing signalized pedestrian crossings from OSM ().
added new option --default.junctions.keep-clear and new attributes for allowing drivers to drive onto an intersection despite the risk of blocking it for cross-traffic. ticket1290
pedestrian crossings may be removed using the new attribute discard.
when splitting an edge, the new node is not removed by option --geometry.remove even when speed and lane count remain unchanged. ticket1842
Connections from and to sidewalks are only generated when also building pedestrian crossings since they are superfluous otherwise. When using pedestrian model nonInteracting these connections are not used (pedestrians jump across intersections between any two sidewalks) and when using model striping, crossings are mandatory.
Bicycle lanes are now imported from OSM (when using the appropriate typemap). ticket1289
Bus lanes are now imported from OSM. ticket1682
Improved control over edge types (typemaps) when importing from OSM. All defaults can now be overridden in a transparent manner and it's easier to add additional modes of traffic than ever before (see documentation).

Tools
GDAL 2.0 is now supported. Thanks to Thomas Lockhart for the patch.
osmBuild.py and server.py no longer use option --geometry.remove-isolated to avoid removing rivers and railways.
Misc
The scripts randomTrips.py and route2trips.py moved from /tools/trip to /tools
The OSM typemaps now disallow vClass tram and ship where appropriate
The tool sumoplayer has been removed because it became obsolete with the introduction of --fcd-output and traceExporter.py. ticket1651

New in SUMO - Simulation of Urban MObility 0.23.0 (Nov 20, 2015)

New in SUMO - Simulation of Urban MObility 0.20.0 (Apr 26, 2014)

Bugfixes:
Simulation:
Fixed bug in the computation of safe velocities. Sometimes the velocity was too high (causing collisions) but most times it was too low (degrading traffic flow).
Vehicles now move to the right lane after passing instead of staying on the passing lane. (see #1139)
Fixed simulation crash related to lane-changing.
Fixed bug where vehicles would no longer stop on the correct lane if they already stopped on the wrong lane.
Fixed bug which would cause collisions due to unsafe lane changes
Fixed crash when terminating the simulation while vehicles were performing continuous lane changing maneuvers (using option --lanechange.duration)
Fast vehicles can now be correctly inserted closely in front of slow vehicles (#1176).
Rerouting fixed for vehicles which are on internal lanes when the rerouting is requested (#1128).
SUMO-GUI:
Fixed crash when using the object locator on some versions of Ubuntu.
Fixed bug where brake lights were shown even though the vehicle was not braking
Fixed bug where train carriages where sometimes drawn onto the wrong lane
The vehicle option 'select foes' now works correctly for foe vehicles on internal lanes
Fixed rare graphical glitch when drawing concave junction shapes
Fixed drawing of segmented vehicles (trains) which are longer than their departPos
NETCONVERT:
Fixed bug which gave some links the wrong priority thus causing collisions (see ticket #1096)
Fixed crash when specifying connections from/to edges which are removed during network building
OSM import no longer fails when encountering empty strings in places where numerical values are expected.
Fixed bug where permissions involving the vClasses custom1 and custom2 were not written correctly.
Fixed bug where connections from a lane were sometimes indexed in the wrong order.
Disconnected nodes can no longer be joined into a cluster when using the option --junctions.join.
Fixed crash when using option --ramps.guess
option --ramps.guess no longer creates ramps if one of the involved connections is a turnaround
traffic lights which get new programs are no longer renamed (see ticket 1157)
DFRouter:
Fixed crash/infinite loop when using option --guess-empty-flows. Use of this option is not (yet) recommended (see ticket 1198)
JTRRouter:
Fixed handling of empty flows (no vehicles) together with a specified start time (see ticket 1109)
TraCI:
instantInductionLoops are no longer included when calling calling traci.inductionloop.getIDList()
Tools:
Fixed bug which prevented traceExporter.py from running
Fixed bug which caused all speed values in NS2 output to be 0
Fixed bug which prevented traceExporter.py option --penetration from taking effect
Enhancements:
Simulation:
The summary of teleporting vehicles now lists all teleports according to their reason
Vehicles now perform an emergency braking maneuver to prevent driving across a red light. If this happens in a simulation it usually indicates that the length of the yellow-phase is to short in relation to the road speed and the braking capabilities. To enable driving across red lights, additional TraCI flags were added (see below).
Improved intersection model which results in less conflicts between vehicles with intersecting trajectories while on internal lanes.
Added a first version of the PHEMlight emission model (contribution of TU Graz)
Rerouting now keeps existing stops and adds new stops which are part of the new route even in cyclic routes
SUMO-GUI:
Reworked drawing of trains to have more realistic carriage lengths. Also some busses are drawn with flexible segments now.
The vehicle parameter dialog now lists the maximum speed of the vehicle's type and the the time headway to the vehicle's current leader
added vehicle coloring mode by time headway
Traffic light colors now distinguish between green major (code G) and green minor (code g) by coloring the minor state with a darker color.
The lane color scheme by vClass now gives fine-grained control over coloring by using the permission bitmask to select the color.
Added menu option Edit->Select lanes which allow...->vClass. Together with the street-coloring option by selection this allows an easy overview of the road network permitted for a given vClass.
Added junction visualization option to disable drawing of junction shapes.
The vehicle coloring mode by max speed now factors in the speed limit on the current lane and the speedFactor of the vehicle. The same color thresholds as in coloring by speed are now used.
NETCONVERT:
added option --osm.elevation which imports elevation data from OSM input (default false).
Conflicts between connections originating from the same edge are now recognized. This can be used to model interaction between right turning vehicles and straight moving non-vehicular traffic on a lane further right.
improved the heuristic for determining junction clusters to be joined when using option --junctions.join. This results in fewer invalid joins. Candidate clusters for manual intervention are indicated.
TraCI:
added method traci.simulation.convert3D() which converts a road position to either x,y,z or lon,lat,alt
added additonal bits to the traci command Change Vehicle State/speed mode to configure the behavior at intersections. This can be used to make vehicles ignore right-of-way rules and also to force them to drive across a red light.
added optional argument 'flags' to traci.vehicle.setStop() in accordance with the Vehicle modification API specification
the API to Areal Lane Detectors was added; thanks to Mario Krumnow and Robbin Blokpoel
it is now possible to retrieve the leading vehicle within a specified range Vehicle API specification
a vehicle may be added using a full specification (which is available via XML input)
Tools:
added tool xml2csv.py which converts all of the XML-output files written by SUMO to a flat-file (CSV) format which can by opened with most spread-sheet software
added tool csv2xml.py for the opposite conversion, requiring an XML schema and also for conversion to Google's protocol buffers xml2protobuf.py
osm/osmGet.py now supports retrieving very large areas by bounding box using the option --tiles . (previously this option was only supported together with option --oldapi which has severe size limitations}}
added option --gpx-output to traceExporter.py which allows exporting vehicle trajactories as GPX files
added option --poi-output to traceExporter.py which allows exporting vehicle trajectories as POIs
added option --vclass to randomTrips.py which ensures that generated trips only depart and arrive at edges permitted for vclass
randomTrips.py now recognizes the network fringe even if the network contains turn-around connections (An edge belongs to the fringe if it contains only incoming or outgoing connections excepting turnarounds). This is important when using the option --fringe-factor for generating plausible through-traffic in small networks.
added two tools for visualising emission behaviour
added some visualisation tools
Other:
TraCI:
TraCI version is now 8
fixed documentation of of command slow down: It changes speed smoothly over the given number of milliseconds (in contrast to command speed which changes using maximum acceleration/deceleration).
All Applications:
Added option --xml-validation with possible values never, always and auto defaulting to auto. This causes all input files to be validated against their respective schema, provided the schema-URL is declared in the toplevel XML-Tag (always requires the schema-URL to be present).
Added option --xml-validation.net to all applications which read .net.xml-files which works like option --xml-validation but applies only to sumo networks (default never since network validation is computationally expensive).
Most of the input and output files have an XML schema now

New in SUMO - Simulation of Urban MObility 0.17.1 (Jun 3, 2013)

New in SUMO - Simulation of Urban MObility 0.17.0 (Jun 3, 2013)

Bugfixes
Simulation
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 occasonaly 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 propper 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.
Enhancements
Simulation
added support for traffic-actuated traffic lights (see Simulation/Traffic_Lights#Loading_new_TLS-Programs, Networks/Building_Networks_from_own_XML-descriptions#Node_Descriptions)
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 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
junction coloring
NETCONVERT
added support for traffic-actuated traffic lights (see Networks/Building_Networks_from_own_XML-descriptions#Node_Descriptions)
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 usefull when importing networks from OpenStreetMap which contain many pedestrian actuated traffic-lights.
Tools
added tool for creating smaller scenarios from a big scenario Tools/Routes#cutRoutes.py
replaced the old trace exporter by a new Tools/TraceExporter tool
experimental Python 3 support for TraCI python API and duaIterate.py
Tutorials
added a tutorial on trace generation
Documentation
added and improved several XML schemata (thanks to Matthew Fullerton)

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

Documentation
Patched CSS issues in IE
Enhancements
building
added configure option --enable-profiling to be used with gprof
Simulation
added the option --routing-algorithm 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 to limit the size of routeDistributions (useful to conserve memory for long-running simulations)
added several new output types by Mario Krumnow: emission output, full output, vtk output, fcd output, and queue output. Thanks!
added the option --fcd-output.geo. If this option is given the output from --fcd-output 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 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.
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.
API version was increased to 5
Added object context subscriptions
Added method remove to the vehicle module
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 specifing 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
Other
general
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.

New in SUMO - Simulation of Urban MObility 0.15.0 (Mar 14, 2012)

Bugfixes:
Simulation
Real time factor in simulation summary is now correct (was off by factor 1000)
Option --route-steps now reads the given number of seconds ahead (input argument was interpreted as milliseconds, inadvertently)
specifying invalid departPos no longer causes an infinite loop
The minimum gap is now outside of the vehicle. This means, a vehicle starts at its position, the minimum breaking distance is in front of the position. This effects the retrieval of a vehicle's position via TraCI, and also the measures collected by detectors - now, the collected vehicle lengths do not contain the minimum distance anymore. see blog entry
consolidating right-of-way rules (again). Networks must be rebuild
fixed crash when using TraCI to set new TLS-programs with less phases (ticket #652)
NETCONVERT
looped ways are now correctly imported from OSM (before, these were pruned from the network)
fixed bug related to --proj.plain-geo (would sometimes crash or produce invalid output)
fixed bug in geometry computation when dealing with 3D-coordinates
fixed bug when joining junctions (did not join as much as requested)
OSM import no longer discards edges with multiple types as long as at least one type is known (this caused missing bridges etc.)
debugged import of VISUM-turn descriptions ("ABBIEGER")
fixed calculation of intersecting lines
GUI
corrected the link numbering
no longer crashes when reload is pressed during running simulation
DUAROUTER
Option --max-alternatives is no longer ignored
clogit probabilities are calculated correctly
Enhancements:
Simulation
Meandata output can now print default travel times / emissions on empty edges (excludeEmpty="defaults")
DUAROUTER
added Option --routing-algorithm. It supports the values dijkstra (default) and astar (new). The newly added astar algorithm uses the euclidean distance heuristic. It routes 30% faster on the road network of Cologne and 40% faster on the road network of Berlin.
In verbose mode, some performance measures of the routing algorithm are given
better defaults for emission based routing
GUISIM
object choser can now filter by selection
NETCONVERT
added Options --speed.offset and --speed.factor. These modify all edge speeds by first multiplying with factor and then adding offset.
added output Option --junctions.join-output FILE. This writes a protocol of joined junctions to FILE. Loading FILE as additional nod.xml reproduces these joins.
All
Logging options are handled consistently
step logging enabled by default, can be disabled for all relevant applications (sumo, duarouter, jtrrouter, od2trips)
Other:
Simulation
traffic light offset is now interpreted as delay. An offset of x delays all phases by x seconds. The old behaviour was to let all phases start x seconds earlier.

New in SUMO - Simulation of Urban MObility 0.14.0 (Jan 11, 2012)

Enhancements
NETCONVERT
changed the way junctions are joined when using --join.junctions; see Networks/Building Networks from own XML-descriptions#Joining Nodes
all output is now written using UTF-8 encoding instead of Latin-1. This should allow the usage of international street names (note that street ids may use only ascii)
added option --proj.plain-geo which writes plain-xml files using geo-coordinates
location information is now embedded in nod.xml files. This makes conversion between net.xml and plain xml lossless.
Importing large OSM Networks is much faster due to algorithmic
improvements:
added options --keep-edges.by-type and --remove-edges.by-type for restricting a network
GUISIM
sumo-gui now parses command line options
general options
boolean options may be disabled from the command line (--help=false)
a single parameter (not starting with "-") is treated as a configuration file
Tools:
added eco routing capabilities to duaIterate.py
Reduced memory consumption of all applications. Also increased speed for some applications. For benchmark values see [#634]

added option --osm.discard-tls (do not use tls definitions when importing OSM)
added option --junctions.join-exclude [,]* (junctions in this list are not joined)
added option --no-left-connections (do not build connections to left)
added optional attributes 'toLane' and 'fromLane' to connection-file element 'reset' (see Networks/Building_Networks_from_own_XML-descriptions#Connection_Descriptions)
added importer for openDRIVE files, see Networks/Import/openDRIVE; many thanks go to Marius Dupuis from VIRES for allowing to use the example files for tests
added importer for matSIM files, see Networks/Import/MATsim (actually already in 0.13.0)
added new plain xml input/output format plain.tll.xml which holds information about traffic lights.
added option --geometry.max-segment-length to restrict segment length by inserting additional geometry points
debugged brakedown on VISUM import
ignore connections for explicitly removed edges (instead of throwing an error)

SUMO-GUI:
can now switch traffic lights back on
Tutorials:
moved tutorials from /docs to /tests/complex for assuring their compliance with the current version; they should though appear in the release under /docs

Tools:
added script tools/net/netdiff.py which creates the plain-xml differences of two sumo networks. The set of difference files can be loaded together with to recreate . This allows for advanced scenario management.
added tools for dealing with turn-ratios
Documentation:
restructured wiki-pages
new static HTML docs generated from the wiki
Other:
updated gl2ps to version 1.3.6
removed MSMsgInductLoop; the functionality was almost the same as for a plain MSInductLoop just that an additional string wasgiven; the functionality can be easily obtained by using proper ids and mapping them to "messages"

New in SUMO - Simulation of Urban MObility 0.13.0 (Nov 3, 2011)

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 /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 and elements
replaced and elements by . Dummy connections (SUMO_NO_DESTINATION) are no longer written.

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 --save-template --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

solved tickets ticket#273 (consolidate speed and acceleration manipulation methods) and ticket#330 (Speed adaptation after receiving SLOWDOWN command not working.)
introduced a way to decide whether safe velocity, maximum deceleration and maximum acceleration shall be considered when changing a vehicle's speed, see: TraCI/Change_Vehicle_State, speed mode (0xb3)
added default "error" return values for teleported/not-yet-inserted vehicles
All lengths are encoded as written in the specification. The correct code for reading length is:
int length = readByte()
if length==0:
length = readInt()
added Contributed/SUMO Traffic Modeler
