Re: [sumo-user] vehicle set speed issue

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

To set the speed after calling executeMove, use the function vehicle.setPreviousSpeed

Hi Jakob,

I guess this is the issue related to excuteMove(). If we call executeMove(), then we move the vehicle and update the speed of the vehicle after this using setSpeedMode(veh, 32) and slowDown() and we finally call step().

Here, the speedTimeline is not getting updated to myState.mySpeed for the current step. This is the reason that getSpeed() is giving old speed before calling slowDown.

On the older branch when executeMove() was not there...I was able to change speed in the current step.

Thanks,

Mahima

In my test, the vehicle changes speed instantly (i.e. also in the departure step). The speed limit isn't even relevant since the speedMode makes the vehicle ignore limits).

Feel free to provide a minimal failure example, preferably as a python script or python traci command log.

Hi Sumo team,

Any inputs from your side?

Thanks

Hi,

I am adding a vehicle on a lane with max depart speed (max speed of this lane is 16.67).

Now, in the same timestep I am moving this vehicle to the next lane (max speed of this lane is 27.78). I want to change the speed of this vehicle to 22.27.

But, when I check the fcd file, the position and lane changes as per the moveTo but speed remains 16.67 only. Please suggest why the speed is not going beyond the depart speed in this timestep and how I can achieve this. Thanks

I am using the following steps:

libsumo::Vehicle::setSpeedMode(2, 32);

libsumo::Vehicle::slowDown(2, 22.27, 0);

libsumo::Vehicle::moveTo(2, lane_id, lane_pos);
