  • Thread-topic: getSpeed vs. getFollowSpeed
hello,

I am trying to understand the difference between getSpeed and getFollowSpeed.
Based on the definition, it seems like getSpeed returns the speed from the current time step whereas getFollowSpeed returns the speed for the next timestep (calculated by the carFollowingmodel).

However, when I printed both speeds it seems like getFollowSpeed returned the current time step's speed and getSpeed returned the speed from the last time step.
I attached a screenshot that shows both getSpeed and getFollowSpeed printed in command window and the current status of the vehicle in simulation.

The first highlighted speed is the 'getFollowSpeed' and the second highlighted speed is the current speed of the vehicle (in simulation).

If 'getFollowSpeed' doesn't return the next timestep's speed, is there any way in SUMO to predict the next timestep's speed?

Thank you,
