Dear friends and users, we are happy to announce the release of SUMO version 1.14.0. The download links are at https://sumo.dlr.de/docs/Downloads.html
This release brings you many new emission models and options for configuring fuel consumption. Our python tools provide new features to simplify traffic demand generation. We also fixed quite a number of bugs some of which were regressions in previous releases. 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 support for emission model PHEMlight V5. Among other things, this permits modeling of fleet aging. - Added support for the HBEFA4 emission model with more than 800 emission classes. - Vehicles at longer planned stops now switch off their engine. - Automated engine start/stop can be modeled. - Actuated traffic lights can now react to downstream jamming - On-demand stopping of public transport vehicles is now possible - netedit - Traffic light mode now supports all phase attributes of NEMA and actuated tlTypes and fully supports the NEMA controller - All attributes can now be reset to their default value by deleting the attribute - Walkingareas are now shown and can be located by id. - Shift-click in demand-stop mode now sets parent element (i.e. vehicle). - Create edge mode now visually previews whether a new junction will be created or an existing junction will be re-used. - Added dialog for fixing / reporting network element problems. - Improved visualization of trips between junctions. - A custom color rainbow is now supported for all data elements. - Added tooltips on mouseover - tools - tls_csvSignalGroups now supports generating actuated traffic lights - osmWebWizard now provides a seamless satellite background - plotTrajectories.py: Now supports plotting by leaderGap - addStops2Routes.py: Added various options to randomize stop assignment (i.e. to model random break-down of cars). - routeSampler.py: now supports option --write-flows poisson to generate flows with poisson arrival pattern. - routeSampler.py: Can now load pedestrian walks as candidate routes. - randomTrips.py: Can now define a timeline of different demand levels. - randomTrips.py: Now supports option --insertion-rate to define demand as vehicles-per-hour and option --insertion-density to define demand as vehicles-per-hour-per-km. - sumo-gui: 3D-view now permits opening vehicle context menu via right-click. - netconvert: Now supports generating NEMA controllers. - netgenerate: Added option --random.type to pick a random edge type from all loaded types. === Bugfixes === - Simulation - Fixed invalid speed when approaching stop for carFollowModel IDM. - Fixed pedestrian collision and jamming - Fixed bug where taxi fails to drop off customer. - Fixed invalid emissions for decelerating / standing vehicles for HBEFA models - inductionLoop near lane end no longer miscounts pedestrians. - Fixed invalid depart and arrival position for persons after taxi ride - Fixed errors when using departSpeed="avg" or departSpeed="last". - Fixed emergency breaking on approach to junction. - Lane-specific speed limits now influence lane-changing decisions. - Fixed bug where vehicles would enter lanes that are separated from a required lane by a forbidden lane. - Fixed collision and other issues related to opposite direction driving. - Fixed various crashes related to mis-configured NEMA controllers - netedit - Fixed crash when loading a network (on very slow computers / builds). (regression in 1.9.0) - Greatly increased rendering speed. (regression in 1.11.0) - Fixed crash when drawing tazRelations. (regression in 1.11.0) - Loaded named routes are now visible again. (regression in 1.12.0) - Setting allow/disallow in create-edge frame is now working again. (regression in 1.12.0) - Fixed incomplete demand output when defining a <flow> and a <pedestrianFlow> with the same id. - Fixed various issues related to containers - Loading and saving a selection is now working for all data elements. - Fixed inconsistent traffic light settings when removing node from a joined traffic light by changing its type. - sumo-gui - Background images (decals) and multi-view settings are now restored on reload. (regression in 1.13.0) - Fixed crash when drawing persons that enter a vehicle. - Detectors are no longer drawn on top of traffic light signals and right-of-way indicators. - Fixed many issues related to the 3D View - netconvert - Fixed invalid reduction in edge shape detail at very dense geometry. (regression 1.12.0) - Fixed crash when loading OpenDRIVE road object validity record. - Fixed missing tram connections at sharper turns on large junctions. - Fixed generation of invalid pedestrian crossings. - Fixed invalid right-of-way rules when using custom contPos at connections from a side road. - TraCI / libsumo - Function vehicle.setAcceleration now supports negative values. - Fixed invalid taxi state after re-dispatch (causing early taxi removal). - Fixed invalid mapping with vehicle.moveToXY onto intersections with parallel internal edges. - Function 'traci.vehicle.rerouteTraveltime' now behaves the same in traci and libsumo in all cases. Previously, the argument currentTravelTimes was ignored by libsumo. The behavior in traci changed slightly: instead of using the current edge speeds and updating them for all vehicles, it now uses the aggregated routing mode (which also reacts to current speeds). - Function traci.person.moveTo is now working (for pedestrians). === Miscellaneous === - Outputs now use attribute period instead of freq whenever denoting a time period. - Updated default bicycle speed on highway.path and highway.cycleway. - Fuel consumption is now given in mg/s instead of ml/s to achieve consistency across liquid an gaseous fuels. For backward compatibility, the option --emissions.volumetric-fuel may be set. - The default parameters of the battery model have been changed to that of a KIA Soul EV (formerly the parameters were for a large electric bus). Issue #10883 Have fun with the new release, Jakob, Robert, Melanie, Johannes, Michael, Yun-Pang, Angelo, Pablo, Mirko and Benjamin
