[sumo-user] 答复: a strange action when change lane

[杜 伟强 <iShadowPrince@xxxxxxxxxxx>]

Thank for your help

 

And I already set the bit 8 and 9 to 00 in my code, and it doesn’t work.

 

So no matter which mode I chose, it will adapt speed to do lanechange ?

 

and I sove this problem by set the speed every step, it work

Hello,
By default, the changeLane command is handled with urgency, that means vehicles will adapt their speed to fulfil the change request as soon as possible.

You can influence this with the setLaneChangeMode command (bits 8 and 9: http://sumo.dlr.de/wiki/TraCI/Change_Vehicle_State#lane_change_mode_.280xb6.29

Jakob

Hello:

       I build a simple network with two edge and every edge has three lanes.

       And I add two same vehicle except there depart lane into network.

 

       When I use traci command to force one vehicle change lane, it will brake and change lane .

       So any one can tell me why? And how to avoid it.

 

       The python code used to change lane is here:

 

       class mylistener(traci.StepListener):

    def step(self, s=0):

        print(s)

        if s == 2000:

            traci.vehicle.setLaneChangeMode("veh0",0)

            traci.vehicle.setSpeedMode("veh0",0)

            traci.vehicle.changeLane('veh0', 1, 3)

 

      and I took a photo to illustrate the phenomenon

     

 

Thank you 😊
