Hello Jakob,
Thank you for your inputs. I used the SpeedMode command but the vehicles
still do not begin to move at the yellow phase.
I came across a discussion
https://sourceforge.net/p/sumo/mailman/message/32796321/
in which one of the user suggests setting tau to a value of zero. But that
doesn't seem to work either.
Desired state - Vehicle begin to move at Yellow phase (which precedes the
Green phase)
Current state - Vehicle do not begin to move at green phase.
Commands tried -
1) traci.vehicle.setTau(vehID, 0)
2) traci.vehicle.setSpeedMode(vehID, 23)
#At the end of red phase I execute following section of code to begin the
vehicles to accelerate-
for veh in stopped_veh:
traci.vehicle.slowDown(veh, 16, 8000)
Please suggest.
