Hello
My vType definition looks like <vehicle id="controlled" depart="1.1"
departSpeed="10" color="1,0,0" lcAccelLat="5000">
I set lcAccelLat very high because I don't want it to be a constraint when I
use changeSublane
Also, I set maxSpeedLat during the simulation with traci and the following
command: traci.vehicle.setMaxSpeedLat(controlled_vehicle,5000)
Then at every timestep I use
traci.vehicle.changeSublane(controlled_vehicle,0.8) that is supposed to make
the vehicle shift by one sublane every timestep. But in reality the shift at
every timestep is much lower than that.
There are no neighboring vehicle.
In my sumo cfg file I have
<lateral-resolution value="0.8"/>
<step-length value="0.1"/>
sumo version: 0.31.0
I am only using release versions but if you think the development version can
solve the problem, I can use it
Thanks for the answer, Best,
Alex

Hello,
maxSpeedLat and lcAccelLat should bet the only constraints on achieved lateral
distance (besides neighboring vehicles of course).
Note, that these values are per second so if you use a lower time-step the
resulting distances are scaled by that as well.
What does your vType definition look like?
What version of sumo are you using?
Did you try the latest development version already?
regards,
Jakob

Hello all,
I am using the sublane model and Traci in order to control the vehicle
laterally.
My goal is to control the time it takes for the vehicle to make a lane change.
But when I try to use changeSublane, the vehicle lateral speed seems to be
constrained by something. I've already set the max lateral speed, lateral
acceleration, max speed and max acceleration to be very high in order not to be
constrained by anything.
I feel like the command changeSublane does not really move the vehicle
laterally by the given amount: how is the real lateral change calculated at
every timestep ?
Best,
Alex
