Hello, when you open the gui, the simulation has not yet started running and so no 'routing device assumed speeds' are available. if you run the simulation for a single step you will see the speed limts. If you continue running the simulation, the colors will start to change, corresponding to traffic effects. For more details regarding the 'assumed speed', see http://sumo.dlr.de/wiki/Demand/Automatic_Routing#Edge_weights
To color by current speeds you can either use 'color by average speed' which uses absolute speed values or 'color by average relative speed' which uses the fraction of averageSpeed/speedLimit for coloring regards, Jakob 2018-09-18 19:46 GMT+02:00 mohsen hs <[email protected]>: > > Dear sumo developers, > > I was wondering if you could please explain a bit more about "*by routing > device assumed speed*", as no such information is provided here: > http://sumo.dlr.de/wiki/Demand/Automatic_Routing# > Investigating_edge_weights > > > Only available info is here : > http://sumo.sourceforge.net/userdoc/Z/Changes_from_ > Version_0.25.0_to_Version_0.26.0.html > > as > > - *Lanes can now be colored by routing device assumed speed.
