Dear friends and users,
we are happy to announce the release of SUMO version 1.11.0.
The download links are at
https://sumo.dlr.de/docs/Downloads.htmlThis release brings you the longest list of changes we have ever had. There are
plenty of enhancements and bugfixes for all applications and we added many new
tools that we hope you'll find useful.
Even though the list below is long, it only contains a subset of all changes.
For the full list, as always see
http://sumo.dlr.de/wiki/ChangeLog=== Enhancements ===
- Simulation
- Traffic light type "NEMA" is now supported and implements a NEMA compliant dual-ring controller. (Thanks to Qichao Wang and NREL)
- Added new electric vehicle model "MMPEVEM". (Thanks to Kevin Badalian and the MMP, RHTW Aachen)
- Detectortype (E1, E2, E3) now support attribute 'detectPersons' to detect pedestrians and passengesr.
- Added option --weights.separate-turns which allows route-search to distinguish travel times by turning direction
- BoardingDuration / loadingDuration are now also applied when exiting a vehicle.
- Parking search now employs memory of previously visited and occupied parking areas.
- Taxi simulation now supports the use of multiple taxi fleets and customer choice of fleet.
- Stopping against the direction of traffic is now possible.
- sumo-gui
- Improve positioning of persons in vehicles.
- Clicking on timestamps in message window now creates breakpoints with a configurable offset.
- Coloring of stop lines can now be switched to "realistic" mode.
- Added extra colors for 'stopped' in vehicle coloring scheme 'by speed'
- Added number of stopped vehicles to network parameters.
- Meso vehicles are now drawn with interpolated positions
- Segment boundaries are now drawn in meso simulation.
- in meso, stops are now indicated when 'show route' is active.
- netedit
- Added new 'Lock' menu to protect different types of objects from inspect,move,select and delete operations.
- Objects within a polygon boundary can now be selected by using the polygon context menu.
- Added options to set the default names for new objects. The new default prefix for edges is 'E' and the new prefix for junctions is 'J'.
- Newly created reverse-direction edges now receive an id based on the forward direction edge and a '-' sign.
- Generic parameters (<param>) of traffic light programs can now be edited in the traffic light frame.
- stopOffset (bike box) can now be defined.
- Object attributes that are computed rather than user-defined (i.e. edge length) are now distinguished in blue.
- Intervals and child-elements of rerouters and VSS can now be inspected.
- <DEL>-key can now be used in inspect mode to delete the currently inspected element.
- Selection mode can now filter for attributes that have/haven't an empty value using '=' and '^' operators.
- TraCI
- Added function 'traci.simulation.getEndTime' to retrieve the --end value that was set when starting sumo.
- addSubscriptionFilterTurn can now be combined (additively) with addSubscriptionFilterLateralDistance and with addSubscriptionFilterLanes.
- Added function 'traci.person.remove'
- Added functions to retrieve aggregated traffic measures from E3-detector.
- Libtraci now supports 'Simulation::start'.
- Added functions to control the split and offset of NEMA-type controllers.
- tools
- Added tool plotXMLAttributes.py to generated 2D-plots from arbitrary attribute of XML files.
- Added tool addTAZ.py for adding taz information to route files.
- Added tool route2OD.py which generates a tazRelation-file (OD-Matrix) from a taz-file and route-file.
- Added tool computePassengerCounts.py to count passenger number in vehicle over time
- Added tool scheduleStats.py to analyze deviations between loaded public transport schedules and simulation timing.
- Added tool parkingSearchTraffic.py to analyze reroute times and distances for parking search traffic.
- Added tool tripinfoByType.py for aggregating tripinfo output by vType
- routeSampler.py: added option --min-count to set mininum number of counting locations for each used route.
- generateParkingAreaRerouters.py: added option --opposite-visible to ensure that parking areas on the opposite direction road are visible.
- addStops2Routes.py received new options to define stops at parkingAreas, add stops to persons and to define stationary (parking) traffic.
- ptlines2flows.py: Added options --stop-duration-slack, --speedfactor.bus and --speedfactor.tram to generated public transport schedules that are robust against delays
- osmWebWizard.py now avoids duplicate sidewalks when building a simulation with persons.
- misc
- netconvert: Added option --osm.sidewalks. This permits to import complete sidewalk data from OSM.
- netgenerate: The option --bidi-probability can now be used to control the generation of reverse edges for grid and spider networks. When set to 0, pure oneway networks are generated.
- od2trips & marouter: tazRelation files (as written by netedit) are now supported as OD-matrix definition.
- duarouter & jtrrouter: Added option --named-routes which writes routes with an id and lets vehicles reference them.
- meso: Tau value of vehicles types now affect simulation (by acting as a multiplier on the segment tau value)
- marouter: --netload-output now includes 'density' and 'laneDensity' and 'speedRelative'.
