Re: [sumo-user] Minimal speed for lane change

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

Hello,

you can use vType parameters

maxSpeedLatStanding and maxSpeedLatFactor (https://sumo.dlr.de/wiki/Definition_of_Vehicles,_Vehicle_Types,_and_Routes#Lane-Changing_Models) to model the dependency between lateral and longitudinal speed.

However, if you set maxSpeedLatStanding=0 vehicles may be unable to complete a strategic lane change and get stuck.

regards,

Jakob

Hello all,

 

we currently work on a co-simulation of a driving simulation with SUMO. SUMo vehicles are transposed in the driving sim environment. In order to make their movements more realistic, we use the option --lanechange.duration with a value > 0. This interpolates the lane change movement but does not prevent lane changes at very low speeds / standstill, e.g. waiting at the stop line.

 

Is there currently any option to disallow lane changes when the longituginal speed is too low? The only thing I have noticed which might be related judging from the name is a constant in the source code of the sublane model (LOOK_AHEAD_MIN_SPEED 0.0).

 

Best regards

Mirko
