Hello,
I am trying to modify 1) position 2) velocity and 3) acceleration of each
actor within my simulation to prescribed values that I chose.
Sumo version: 1.16.0 - interfaced with flow
What I currently do is
----------------------------
for loop over all the actors
self.k.kernel_api.vehicle.setPreviousSpeed(
vehID=actor_id,
speed=wanted_velocity - wanted_acceleration*simulation_step)
self.k.vehicle.moveToXY(
veh_id=actor_id,
edge_id=actor.edge,
lane=actor.lane,
posX=actor.pos_2d[0],
posY=actor.pos_2d[1],
angle=self.k.vehicle.get_angle(actor.actor_id),
keepRoute=1,
)
self.k.kernel_api.vehicle.setAcceleration(
vehID=actor.actor_id,
acceleration=actor.acceleration * 2,
duration=self.sim_step)
end for
self.k.simulation.simulation_step()
--------------------------------------
With this approach I can successfully set each actor position velocity and
accelerations to my values. However it seems the success is really
depending on the sequence of steps (for example setting moveToXY prior to
setPreviousSpeed results in an unsuccessful final outcome - no error, just
not getting what I want).
Therefore, I have the following questions:
0) Is what I am doing 1) feasible and 2) sound, given the above mentioned
sequence of commands?
1) I tried to use setSpeed multiple times instead of setPreviousSpeed, but
it doesn't work. Can you help me understand why?
2) It seems weird that I have to double my wanted acceleration (see
acceleration=actor.acceleration * 2) to get the final wanted result. Why is
that happening?
Thanks in advance for the help!

Stefano.
