    • Added functionality for retrieving lane, position and stopped vehicles for traci domains 'busstop', 'parkingarea', 'chargingstation' and 'overheadwire'. Issue #5952, #7099
    • The python client now supports the optional argument 'traceFile' in function traci.start which records all traci commands to the given file (also works for libsumo.start). The optional boolean argument 'traceGetters' can be used to switch off tracing of data retrieval functions. Issue#6604, #7481
    • Added function 'vehicle.replaceStop' which replaces the upcoming stop with the given index and automatically adapts the route to the new stop edge. Issue #7226

    • Added new tool addStopDelay.py to add random stop delays to a route file. Issue #5209
    • routeSampler.py: Now supports option --weighted. This causes routes to be sampled according to their probability. The probabilty can either be specified explicitly using route attribute 'probability' or implicitly if the same sequence of edges appears multiple times in the the route input. Issue #7501

Other#

  • Simulation
    • Route attribute 'period' was renamed to 'cycleTime'. Issue #7168
    • Total simulation running time is now in seconds rather than milliseconds. Issue #7255

  • TraCI
    • In the python client, function vehicle.getLeader can now optionally return the pair ("", -1) instead of 'None' if no leader is found. The new behavior can be enabled by calling function traci.setLegacyGetLeader(False). In later versions this will be the default behavior. The return value 'None' is deprecated. Issue #7013
    • The function 'libsumo.vehicle.getNextStops' now returns a list of StopData objects rather than a list of tuples (the same result type returned by getStops) but different from the return type of 'traci.vehicle.getNextStops'. If the python script should be fully compatible between traci and libsumo, the new function 'vehicle.getStops' must be used.
  • Tools
    • randomTrips.py now generates repeatable results by default (by using a fixed default seed). To obtain the prior random behavior without specifying a seed, the option --random can be used (just like for sumo). Issue #6989

    • Trip, flows, personTrips and walks with attributes fromJunction,toJunction and viaJunctions are now supported when setting option --junction-taz. Issue #6474
    • Trips can now be written with attributes fromJunction and toJunction and viaJunctions by setting option --write-trips.junctions. Issue #6474
    • When using trip attributes fromXY, fromLonLat, etc. the given positions can now be mapped to junctions instead of edges by setting option --mapmatch.junctions. Issue #6475
  • jtrrouter
    • Added option --sources-are-sinks (shortcut -S). When this option is set, all flows will terminate upon reaching the from-edge of another flow. Issue #6601
    • Added option --discount-sources (shortcut -D). When this option is set, the flow departing at an edge will be reduced by the amount of traffic that has reached this edge from upstream flows. When combined with option --sources-are-sinks, upstream flows will terminate at a downstream edge when the source flow number has been reached. This can be used to build a scenario from flow counts at arbitrary locations. Issue #6601
  • TraCI / Libsumo
    • Added context subscription filter that filters in a given range around the vehicles route 'addSubscriptionFilterLateralDistance'. Issue #6287
    • Libsumo now supports context subscription filters
  • Tools
    • duaIterate.py now supports intermodal scenarios. Issue #6403
    • Added duaIterate.py option --measure-vtypes to improve accuracy of measured travel times when different vehicle types can use different lanes.
    • Added tileGet.py to retrieve image tiles from public servers. Issue #6279
    • Added randomTrips.py option --personrides LINE to generated person rides with the give line id.
    • Added randomTrips.py option --junction-taz to generated trips, flows, personTrips and walks between junctions. Issue #6474
    • Added the ability to download Satellite image backgrounds (using tileGet.py) in osmWebWizard. Issue #6481
    • Added new tool jtcrouter.py to build a traffic demand scenario based on turn-count data (this uses jtrrouter in the background). Issue #6229
    • Added new tool routeSampler.py to build a traffic demand scenario based on turn-count and edge-count data. This tool samples from a given set of routes to meet the detected counts. Issue #6616
    • Added new tool turnCount2EdgeCount.py which converts turn-count data into edge-count data. Issue #6619

Other#

  • Build
    • removed autotools build
  • sumo-gui
    • the settings file no longer accepts the element breakpoints-file (command line option is still there)
    • renamed attributes in the settings (breakpoint.value to breakpoint.time and decal.filename to decal.file)
    • Default settings values 'show link junction index' and 'show link tls index' changed because their interpretation varies after #6376. Old GUI-setting files must be updated to achieve the default look.
  • TraCI
    • traci.lane.getLinks (python) now returns the extended descriptions by default, the older behavior should not be used anymore (but is still available using a second parameter)
