all <node>-attributes are now also supported within a <join> element to affect the joined node. Issue #1982
Various improvements to the generation of traffic light plans. Issue #5191, Issue #5192, Issue #5194, Issue #5196
If a custom ID was assigned to a traffic light (different from the junction ID), it will no longer be joined with other traffic lights when option --tls.join is set. Issue #5198
Lane widths are now imported from VISSIM networks. Issue #5216
Changed option default for --opendrive.advance-stopline to 0 to improve generated geometries in most cases.
Roundabouts can now be disabled and removed by setting the node type to right_before_left Issue #2225
netedit
Major improvement in rendering speed
Junction context menu function split junctions now restores original node ids Issue #4992
The new function split junctions and reconnect now recreates edges heuristically. Issue #4998
can now edit tls phase attributes next and name. Issue #4788
can now load additionals and shapes using -a "file.xml" or --additionals "file.xml". Issue #5049
Connection attributes dir and state can now be inspected and used as selection filter. Issue #3858
Can now locate objects by their name (streetname or generic parameter key="name"). Issue #5270
Roundabouts can now be removed by setting the node type to right_before_left Issue #2225
Added option --write-trips<BOOL> to output trips instead of routes. This is useful for validating trip input that shall be routed during simulation. Issue #4971
Added option --write-trips.geo<BOOL> to write trips with attributes fromLonLat, toLonLat instead of from and to
Reading trips with attributes fromLonLat, toLonLat, fromXY, toXY, viaLonLat, viaXY is now supported. Issue #2182
Time losses due to passing intersections from a non-priority road are now anticipated. The anticipated loss can be configured using the new option --weights.minor-penalty<FLOAT> (new default 1.5, previous behavior when set to 0). Issue #2202.
Added option --weights.random-factor<FLOAT> to randomize routing results with bounded deviation from optimality. Issue #1353
TraCI
Added multi-client support to TraaS (setOrder) Issue #4957
traci.vehicle.getNextTLS now returns upcoming traffic lights for the whole route of the vehicle (before, only traffic lights until the first required lane change were returned). Issue #4974
Added functions trafficlight.getPhaseName and trafficlight.getPhaseName to all clients. Issue #4788
Extended the function traci.vehicle.openGap() to include an optional parameter specifying a reference vehicle. Issue #5151
Added function traci.vehicle.getNeighbors() and convenience wrappers (getLeftFollowers(), etc) to retrieve neighboring, lanechange relevant vehicles. Issue #5170
Added function person.getSlope to all clients. Issue #5171
Function vehicle.changeLaneRelative(vehID, 0) can now be used to a pin a vehicle to the current lane. Issue #5178
The default algorithm for averaging road speed to estimate
rerouting travel
times was
changed from exponential average (0.5) to moving average
(180s). This is better suited for averaging traffic light
cycles in urban road networks. To restore the old behavior, the
option --device.rerouting.adaptation-weight 0.5 can be used. Issue #4975
netconvert
Turn-arounds are no longer built at geometry-like nodes by
default (when there is a node but no intersection so there would
only be straight connections and turn-arounds). The old behavior
can be restored by setting option --no-turnarounds.geometry false. Issue #5121
The default priorities for different railway edge types imported
from OSM haven been changed so that all types use a different
priority value.
The assigned edge speed for unrestricted motorways was lowered
to 142km/h (from 300km/h) to better reflect real world speed
distributions (together with the default speed factor
distribution). Also, the default motorway speed was lowered from
160km/h to 142km/h for the same reason. Issue #5434
TraCI
TraCI Version is now 20
Function trafficlight.setCompleteRedYellowGreeenDefinition now
expectes the 5th component next to be a list of integers when
defining phases. Function
''trafficlight.getCompleteRedYellowGreeenDefinition now
returns a list of integers as the 5th component (next) when
defining phases. Custom clients must be patched to handle this.
Function trafficlight.setCompleteRedYellowGreeenDefinition now
accepts name as an optional 6th component when defining
phases. Function
''trafficlight.getCompleteRedYellowGreeenDefinition now
returns name as the 6th component when defining phases. Custom
clients must be patched to handle this.
TraaS function Simulation.findRoute now returns SumoStage
object (containing all data returned by the TraCI API) instead
of SumoStringList with just the edge IDs
TraaS function Simulation.findRoute now returns
LinkedList<SumoStage> (containing all data returned by the TraCI
API) instead of LinkedList<SumoStringList>
