Dear friends and users, we are happy to announce the release of SUMO version 1.18.0. The download links are at https://sumo.dlr.de/docs/Downloads.html
This release brings many bug fixes including a critical fix to the HBEFA4 model and refinements to the netedit python-tool features introduced in the previous release. 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 http://sumo.dlr.de/wiki/ChangeLog ### Enhancements - Simulation - Added device.taxi.idle-algorithm value 'taxistand' which makes idle taxis return to a pre-configured set of locations. - Can now configure vehicle behavior after colliding with a pedestrian. - The SSM-device now supports the new surrogate safety measure "MDRAC". - Vehicles can now be configured to ignore specific vehicles/types during car-following - netedit - Implemented new dialog for setting netedit and sumo options. This dialog supports option help, file selection dialogs and permits dynamic filtering of listed options. - Now supports trips and flows between TAZs. - netconvert - OpenDRIVE import: now supports road objects from connecting roads. - OSM import: typemap osmNetconvertRailUsage.typ.xml now imports service designation. - Added option --railway.signal.guess.by-stops to add rail_signal nodes to a network that is lacking them. - When using option --tls.rebuild, the tltype can be changed by setting option --tls.default-type. - TraCI - Added functions 'lane.getAngle' and 'edge.getAngle'. - Added function 'vehicle.getJunctionFoes'. - Function traci.vehicle.setStopParameter and getStopParameter now supports optional argument customParam=True to work with user defined stop parameters. - 'vehicle.setImpatience' and 'vehicle.getImpatience' now set/get the dynamic impatience value which is affected by waitingTime - vehicletype domain now support the functions set/getBoardingDuration and set/getImpatience. - tools - randomTrips.py: added options --from-stops and --to-stops to define pedestrians, personTrips and person rides from and to stops (i.e. busStop). - plotXMLAttributes.py and plot_trajectories.py now show the plot by default. - plotXMLAttributes.py: Now supports attribute value @DENSITY to create density plots. - routeSampler: Added option --taz-files and support for loading origin destination matrices in tazRelation format. - scheduleStats.py: Now permits analysis of planned and actual travel time between pairs of stops. - tileGet.py now supports option --parallel-jobs to speed up data retrieval. - checkStopOrder.py: more options and features for table generation - generateRailSignalConstraints.py: now supports portion working (vehicles with depart="split"). ### Bugfixes - Simulation - Setting param vTypes for actuated and delay_based tls detectors is working again. (regression in 1.15.0) - Fixed invalid emission and consumption outputs for the HBEFA4 emission classes (model was calibrated on km/h instead of m/s). - The simulation now aborts when encountering an invalid stop definition (unless option --ignore-errors is set). - Fixed crash when loading state with vehicles that have triggered departure. - Fixed crash after rerouting and losing a stop. - A parkingReroute now works even if the parkingArea on the current edge is not included in the alternatives list. - IDM no longer violates right of way due to imprecise stopping at minor link. - Fixed multiple problems causing emergency braking and collisions - Fixed multiple problems with bidirectional lane use - netedit - Fixed crash when importing OSM data direclty. (regression in 1.16.0) - Saving plain xml now works when selecting an existing plain-xml file to define the output prefix. (regression in 1.16.0) - Fixed invalid undo operation after moving a set of network elements. (regression in 1.16.0) - Fixed segfault when closing netedit and no net is loaded (regression in 1.17.0) - Fixed spacing for person mode path info subframe. (regression in 1.17.0) - Loading Data Elements via menu item is working again. (regression in 1.17.0) - netdiff-dialog now permits to change the output prefix. - Fixed invalid default values in netgenerate dialog and tool dialogs. - Boolean options can now be reset in tool dialogs. - A person with a single stop stage is now visible after loading. - Z value is no longer applied twice in move mode. - Using netedit to define custom detectors for actuated traffic lights is now working. - netconvert - Fixed invalid connection permissions after joining junction. - Fixed broken network after setting option --tls.rebuild. - Fixed classification of turnaround connection on some divided highways. - OSM: fixed incomplete public transport route. - OSM: fixed problems with one-way bus and bicycle infrastructure. - OSM: fixed crash when using option --osm.turn-lanes. - Fixed unsafe signal plan at joined tls. - various fixes for bidirectional rail and road edges - duarouter - Fixed railway routing failure if the stop is defined on a short buffer edge (also applies to sumo). - Fixed invalid ride in output when starting personTrip on rail edge. - Fixed invalid route output when a personTrip provides alternative vehicle modes. - activitygen: fixed crash when there are no work positions within a city. - TraCI - Fixed crash when calling traci.load and running with sumo-gui. (regression in 1.16.0) - Calling vehicle.insertStop now preserves the original route edges beyond the inserted stop. - Fixed missing vehicle type in saved state and vehroute-output for vehicle added via TraCI. - Tools - Fixed mouse control in several game scenarios. (regression in 1.17.0) - Fixed error when calling some tools without argument. (regression in 1.17.0) - gridDistricts.py: Networks with non-normalized offsets now create correct taz shapes. ### Miscellaneous - Many tools now repurpose the -c shortcut for loading a configuration. All options that previously used this shortcut continue to work with the respective long option name. - plotXMLAttributes.py and plot_trajectories.py no longer create output file 'plot.png' by default (use option --output FILE instead) - netconvert: option --osm.all-attributes now defaults to exporting all attributes because the explicit list of attributes (--osm.extra-attributes) now defaults to value all. - netconvert: increased default bike path width. - traci.simulationStep has no return value on Python any longer (similar to the other languages), use traci.simulationStepLegacy for the old behavior. - The default file extension for netedit configuration files was changed from .neteditconfig to .netecfg for consistency with other config extensions. Have fun with the new release, Robert, Johannes, Michael, Yun-Pang, Pablo, Mirko, Benjamin, Angelo and Jakob
