Re: [sumo-user] VariableSpeedSigns in TraCI

[Sasan Amini <aminissn@xxxxxxxxx>]

That seems to be a bit more complicated than I thought.
Regarding the workaround, I guess using VSS is more practical because
it affects all the downstream lanes (overwrites the vehicle maxSpeed)
while using traci.lane.setMaxSpeed would only change the speed limit
in the lane where the vss is defined. Moreover, it takes the fun away
from the SUMO-GUI by not changing the VSS icons.
