  • Thread-topic: Many collisions with CACC model compared to ACC model?

Hi,

 

Please, find below a description of a problem that find each time I run simulations.

It is related to the CACC car following model.  

 

 

Problem description:

In SUMO simulations, I have a case where a car is stand still on a motorway with the purpose to provoke collisions.

Peculiarly, A huge number of collisions emerges for the CACC model, while I have no collisions for the ACC model within the exact same conditions.

 

I have a minimal number of parameters for the CACC or ACC model. I’m not using traci to initiate a TOR

There is also no difference whether the parameter “has.toc.device” is set to True or False for different simulations.

Do anyone knows why there is a huge difference?

 

Here, you find the number of collisions when using the CACC model for CAVs and CVs
