Dear friends and users,
we are happy to announce the release of SUMO version 1.23.0.

This release brings many new python tools for remapping simulation inputs
between different networks and enhances or fixes tools for working with traffic data.
All car-following models now support speed-dependent acceleration and netedit
now supports working with multiple route- or additional-files simultaneously.
There are many more features and fixes in this release and the most
important ones are listed below. For a full list of changes, as always see
https://sumo.dlr.de/Changelog.
### Enhancements
- sumo
- All carFollowModels now support attributes speedTable, maxAccelProfile and desAccelProfile to model speed-dependant limits on acceleration
- Zipper junctions with an arbitrary number of conflicting connections are now supported
- public transport rides that are created for a personTrip now use any vehicle that stops at the destination by default.
- Road slope is now used in HBEFA3 and HBEFA4 computation
- netedit
- Each object now tracks the file from which it was loaded to facilitate working with projects where multiple route- or additional-files are used
- Menu-toggle 'show bubbles' is now available in additional editing modes and always toggles between showing junction shapes and junction bubbles.
- netconvert
- OSM: newer tagging schemes for on-street parking are now supported
- sumo-gui
- busStops now support param emptyColor to distinguish virtual stopping places from normal busStops.
- Color settings dialog now features 'recalibrate rainbow' controls for dynamic vehicle coloring schemes
- TraCI
- vehicle.setSpeedMode now supports a 7th bit to control adherence to the road speed limit
- Addedd function person.getWalkingDistance
- Added lanearea functions getIntervalMeanTimeLoss and getLastIntervalMeanTimeLoss
- subscriptions to all complex types are now working
- Tools
- randomTrips.py: When option --validate is set, the generated amount of vehicles is guaranteed (by replacing invalid trips with new valid trips)
- remap_additionals.py: convert infrastructure from one network to another network (which may differ in geometry, lanes and edge splits)
- remap_renamed.py: convert route files and additional files after renaming network ids (i.e. with --numerical-ids)
- remap_network.py: New tool for finding correspondence between networks based on geometry
- gtfs2pt.py: now supports option --stops for giving a list of candidate stop edges to guide mapping. This can can greatly improve running time
- generateDetectors.py: new tool for generating detectors on arbitrary network edges
- The tools mapDetectors.py and edgeDataFromFlow.py received new options to handle more varied inputs of real-world traffi counts
- csv2xml.py: Added option --flat to convert arbitrary csv files without a schema
- generateTurnRatios.py: added option --split-types to create type-specific turn ration attributes
### Bugfixes
- sumo
- Fixed invalid stop position at busStop when a vehicle became blocked while the stop was occupied (regression in 1.6.0)
- Fixed crash when using rail signal on shared lane (regression in 1.22.0)
- Fixed invalid waitingTime in personinfo output
- Fixed failure to overtake two parallel stopped leaders
- Fixed oscillating speed during zipper merging
- Fixed invalid rail behavior after rerouting
- Fixed deadlock between vehicle and pedestrian on walkingarea
- Fixed bug where right-turning vehicle ignores bicycle on indirect left turn
- Fixed several stationfinder device bugs
- Taxi no longer disappear after teleporting in a jam.
- netedit
- Restored functionality for setting custom geometry point by entering values (regression in 1.20.0)
- Improved visibility of internal junction markers on connections (regression in 1.20.0)
- Move mode with elevation checkbox active now shows elevation numbers again when zoomed out (regression in 1.20.0)
- Fixed crash in tls mode (regression in 1.20.0)
- Fixed missing edge colors when defining person walk (regression in 1.21.0)
- Fixed overly large endpoint markers in move mode (regression in 1.22.0)
- Fixed crash when TL controlled junction overlaps with another uncontrolled one (regression in 1.22.0)
- Fixed bug where shift-click to inspect lane only works after moving mouse (regression in 1.22.0)
- Fixed crash after deleting edges with opposite-lane information
- sumo-gui: Fixed scaled/unscaled rendering of rail carriages on edges whith custom length
- netconvert
- Fixed unsafe program transition from 'G' to 'g' (regression in 1.20.0)
- OpenDRIVE import: Fixed invalid simplification of elevation data on straight roads
- Fixed invalid connections when using option --osm.turn-lanes
- Fixed invalid bus connections when guessing
- Fixed invalid right of way with respect to left-turns from the oncoming direction at junctiop type left_before_right
- Fixed invalid internal lane shape when importing OpenDRIVE
- Fixed failure to join junctions
- durarouter
- Fixed invalid route output when loading invalid routes with stops and setting option --ignore-errors
- vClass-specific speed restrictions are now working
- TraCI
- Fixed bug where traci.vehicle.moveToXY matched onto the wrong internal lane
- Fixed bug where vehicle.slowDown required an additional simulation step to reach the taget speed and vehicle.setAcceleration was achieving the wrong acceleration
- Fixed invalid active person count after person removal
- Subscriptions to methods with additional parameters now work in libsumo
- libsumo subscriptions no longer ignore begin and end time
- Tools
- sumolib.net.lane.getClosestLanePosAndDist now gives correct results when lane length differs from shape length
- gtfs2pt.py: Fixed multiple bugs causing faulty routes to be written
- ptlines2flows.py: Fixed multiple bugs causing faulity routes to be written
- distributeChargingStations.py: Fixed invalid position of generated parking area when input contains negative positions
- loading tool config with multiple positional input file arguments now works
### Miscellaneous
- The new default emission model is now HBEFA4. Please note that this means a major reduction especially in the values for CO and HC at low speeds.
- TraCI: the functions simulation.getBusStop* are deprecated in favor of the corresponding functions in the busstop domain
Have fun with the new release,
