Dear friends and users, we are happy to announce the release of SUMO version 1.12.0. The download links are at https://sumo.dlr.de/docs/Downloads.html
This release brings you exciting changes for the simulation of traffic lights as well as many new features to simulate cruising for parking. It also fixes a regression in intermodal network building and therefore come a bit ahead of schedule. 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 lights of type 'actuated' and 'delay_based' now support attributes 'earliestEnd', 'latestEnd' and param 'cycleTime' to configure coordination. - Traffic lights of type 'actuated' now support custom logical conditions for switching. - Many new parameters for traffic light type 'NEMA' to support different operating modes - Parking search now permits opportunistic parking along the way and configurable "intuition" about target occupancy. - Persons are now included in saved simulation state when setting option --save-state.transportables. - Vehicle attribute departSpeed now supports the values 'last' and 'avg' (both support higher insertion flows than alternative values). - sumo-gui - Many enhancements to the traffic light "Track Phases" window. Among other things, it can now show the state of detectors and switching conditions. - Parameter tracker window supports multiple plots and shows the values at the cursor - Additional parking search visualization for vehicles and roads - Vehicle size can now be scaled by attribute. - All text setting now have the checkbox "only for selected" to display text selectively. - netedit - Trips and flows between junctions (fromJunction, toJunction) are now supported. - The name prefixes for all created additional elements can now be configured and their defaults have been shortened. - All elements of a side frame can now be collapsed/expanded. - Loading and setting of vTypeDistributions is now supported. - Lane change prohibitions (changeLeft, changeRight) are now visualized. - Selections can now be modified based on object hierarchy (i.e. to selection junctions for all selected edges). - Improved visibility for short edges. - netconvert - OSM: import of public transport now supports share_taxi (PUJ) and minibus. - OSM: attribute turn:lanes is now used to determine lane-to-lane connections when option --osm.turn-lanes is set. - Several improvements to OpenDRIVE import and export - tools - generateParkingAreaRerouters.py: multiple new options to customize parking search - addStops2Routes.py: Can now generate stationary traffic to fill each parkingArea to a configurable occupancy. - Added tool generateParkingAreas.py to generate parkingAreas for some or all edges of a network. - randomTrips.py now supports option --random-depart to randomize departure times. - randomTrips.py: now support option --fringe-junctions to determine the fringe from junction attribute 'fringe'. - tripinfoByType.py: now supports option --interval to aggregated data by depart time or by arrival time - emissionsDrivingCycle now permits loading of electric vehicle params via the new options --vtype and --additional-files. === Bugfixes === - simulation - Fixed bug where persons could enter the wrong vehicle and thereby cause a taxis simulation to crash. (regression in 1.11.0) - Fixed various issues with emergency vehicle behavior - Fixed various bugs in parking search - Fixed varous bugs in taxi simulation - Fixed bugs for carFollowModels EIDM and Wiedemann - Fixed junction collisions - Fixes to opposite direction driving - Several bugfixes for traffic light type 'NEMA' - netedit - Fixed bug preventing inspection of tazRelations. - Fixed invalid weights of sinks and sources when loading taz from file. - Fixed crash on undo after resetting connections. - Fixed missing 'end' attribute when converting trip to flow. - Routes now longer have a color unless set by the user. - Stops can no longer be created on edges that do not belong to the route. - When splitting an edge, all routes passing that edge are now adapted. - sumo-gui - Fixed crash when using guiShape "truck/trailer" or "truck/semitrailer" for short vehicles. (regression in 1.11.0) - Fixed occasional freezing during person simulation. - netconvert - Fixed invalid network when importing public transport and sidewalks. (regression in 1.10.0) - Fixed multiple bugs in OpenDRIVE import (Re-import your networks for improved geometrical accuracy) - Fixed unsafe location of internal junctions that were causing collisions in the simulation. - Fixed unsafe intersection rules that could cause emergency braking at pedestrian crossing. - Fixed invalid connectivity at motorway ramp when importing OSM lane change prohibitions. - Options --tls.group-signals and --tls.ungroup-signals now work for pedestrian crossings. - meso - Fixed invalid stop arrival time in meso. - Fixed invalid ride depart time and route length when starting directly after stop. - Dynamically modified road permissions (i.e. closingReroute with disallow and closingLaneReroute) are no longer ignored and can now cause jamming. - Fixed invalid capacity in intermodal scenario. - duarouter - Fixed invalid route output when using option --remove-loops on routes with multiple loops. - Fixed inconsistent railway routing results for stops on consecutive bidi-edges. - marouter: Fixed wrong begin and end times in marouter output with additive traffic. - traci: Fixed bug where calling changeSublane with high 'latDist' value, causes exaggerated maneuverDistance. === Miscellaneous === - SUMO can now be installed from python wheels. This provides up to date release and nightly versions (via test.pypi.org) for all platforms. #4639 - Added documentation on road capacity and headways. - Added documentation for signal plan visualization Have fun with the new release, Laura, Pablo, Jakob, Robert, Melanie, Johannes, Matthias, Michael, Yun-Pang and Angelo
