Now using version 0.32.0, the maximum lateral speed is always 1 m/s when I use changeSublane. I set maxSpeedLat and lcAccelLat very high. I want the maximum lateral speed to be higher than 1 m/s.
What other parameters could be constraints ? I'm using a simple net with 2 lanes in the same driving direction, only one vehicle, with a lateral resolution of 0.8 and a lane width of 3.2.

Therefore, it could be a bug in 0.31.0. regards, Jakob 2017-12-13 9:16 GMT+01:00 alex goupilleau via sumo-user <[email protected]<mailto:[email protected]>>: 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 ________________________________ De : Jakob Erdmann <[email protected]<mailto:[email protected]>> Envoyé : lundi 11 décembre 2017 16:35 À : alex goupilleau; Sumo project User discussions Cc : sumo-user Objet : Re: [sumo-user] Constrained lateral movement 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 2017-12-11 15:06 GMT+01:00 alex goupilleau via sumo-user <[email protected]<mailto:[email protected]><mailto:[email protected]<mailto:[email protected]>>>: 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 ?
