Thank you very much! and Looking forward to receive your answer soon

I noticed that in your paper you mention the NGSIM dataset. the input range of the vehicle is 180 feet, All vehicles observed in the same time frame should be outside this range, how did you deal with it.
In Apollo, all vehicles at a time are taken into account, what is the difference between the two?

If the same time frame will be saved as multiple training sequences, will the amount of saved data be too large? Especially in NGSIM because it has a lot of data to process.
