| Re: [sumo-user] Ovetaking via TraCI |
Veins version 5 is compatible with SUMO 1.2. which already uses TraCI API version 20. I recommend upgrading Veins._______________________________________________Am Do., 9.

In my first email I said i'm using the SUMO 1.2.0 but in fact Veins is only compatible with SUMO 1.0.1 and I am using this version. I noticed that even using the attribute lcOpposite="0" the vehicles remains performing overtakings in SUMO 1.0.1.To test, I run my network in SUMO 1.4.0 and noticed that in this version the attribute lcOpposite="0" works fine and no overtakings occurs. But when I run Veins with SUMO 1.4.0 the following error occurs:I think the best approach is to find the change that corrects this behavior and applies in version supported by Veins TraCI interface (generating a new version 1.0.1 with the fix applied). The other option is to adapt the interface to support SUMO 1.4.0. The problem is that is approach requires many more changes. What is your opinion on these approaches and what might be the best way to solve this problem?Thanks in advance!Em qui., 2 de jan. de 2020 às 18:28, Jakob Erdmann <namdre.sumo@xxxxxxxxx> escreveu:1)a) you can use<vType>-attribute lcOpposite="0" to disable automatic opposite direction drivingb) you can use laneChangeMode to disable the interaction between the laneChange model and traci: https://sumo.dlr.de/docs/TraCI/Change_Vehicle_State.html#lane_change_mode_0xb62) I don't think this is a Veins issue but rather the laneChange model at work (and possible a bug in the way that the duration argument is interpreted for opposite-direction driving). The answers to 1) should take care of this.regards,Jakob_______________________________________________Am Do., 2.

I would like to trigger overtaking maneuver via TraCI (from Veins, using V2V to get environment awareness). But I'm having two issues that I would like a suggestion from you:1. To perform the overtaking, I include the 'neigh' information in the network. With this, Sumo perform automatically the overtaking of some vehicles. Is there any way to disable automatic overtaking in Sumo so that only TraCI overtaking occurs?2. When I trigger the overtaking via changeLaneRelative TraCI command, in some cases, the vehicle starts jumping between the current line and the opposite line several times. I tracked the submission of the command and it is occurring only once. Is there a mechanism in Veins that forces the vehicle back to its current lane even before the changeLaneRelative timeout?Thanks in advance!--Att.
