Re: [sumo-user] Platooning functioning

[Iñaki Cejudo Fresnadillo <icejudo@xxxxxxxxxxxxx>]

Hi Mirko, 

Thank you for your response. Regarding this issue, I have continued working trying to simulate a shuttle of some vehicles so they maintain formation for the whole simulation. I tried to change car-following and lane change parameters but without having success.

My next approach has been in every step of the simulation, move the follower vehicles to a previous position of the leader vehicle. In the example I attached, just a leader and a follower, always crashes in step = 22 with no specific logs, just "Exception has occurred: FatalTraCIError". I attached two pictures to better understand the simulation. These are from the step before the simulation crash. What could be the cause? Thank you.

Best Regards, 

Iñaki

Hi Iñaki,

 

I can confirm that your goal cannot be achieved using simpla, as this module is meant to form platoons spontaneously. It may work in some networks with few lane changes and platooning vehicles following the same route, but cannot be guaranteed at all. The vehicles still act indepedently: they may let other vehicles change onto their lane, stop at traffic lights while the front vehicle passed etc.

 

In theory, TraCI includes all the tools to control the vehicles remotely and implement your own platooning algorithm:

• enable / disable speed and lane change checks
• overrule speed, issue lane changes

This control does not necessarily happen all the time, but you need to step in at critical points like intersections.

 

Best regards

Mirko

Hello, 

 

I recently started working with the Simpla module in SUMO, researching what can be done regarding platooning. 

From what I have tried so far, the vehicles enter and leave platooning mode depending on the conditions of the simulation and the simpla configuration. What I would like to achieve is to create a platoon of, let's say, 5 vehicles, and those 5 vehicles keep their formation during all the simulation (representing a shuttle). What I have achieved so far is that these vehicles form the platoon at the start of the simulation but as the simulation goes on, they leave the formation and change lanes and leave platooning mode. 

Is it possible to achieve what I am looking for? Any tips on how to do it? Thank you.

 

Regards, 

 

Iñaki
