logging accelerations and velocity for multiple cars

[amezzali]

Hi All,

I'm trying to get the acceleration and velocity profiles of multiple self-interacting cars (simulated on autopilot, for instance). As result, I would like to obtain a log file with timestamp, id_vehicle, accelerations and velocity value. However I'm struggling to find an efficient and simple solution

In my last attempt, I've started from the generate_traffic.py example, but I've not found an easy way to incorporate the imu_sensor for the npcs. Another possibility is to use the automatic_control.py example and create multiple vehicles, but I'm not sure it's the right way to proceed.

Do you have any idea on how can I approach the problem?

many thanks!

Get the world snapshot.
In world snapshot you can have all the actors in the simulator. You can then extract the information like velocity, acceleration, angular velocity of all the actors.
