The mapping is: 0: LEFT, 1: RIGHT, 2: STRAIGHT, 3: LANEFOLLOW, 4: CHANGELANELEFT, 5: CHANGELANERIGHT The command does correspond to the command in CIL, but additionally modern benchmarks consider multi-lane roads so there are additional commands for lane changes. Command corresponds to the navigational command in Table 1 of the paper. In that table we compare the effect of using either the command or the target point.
For the final model I use both because the target speed MLP classifier in figure 7 otherwise has no conditional signal (Target point is input to the GRU). Though adding the command didn't seem to have any measurable effect, so conditioning is likely not so important for longitudinal control.
The commands are provided by the carla leaderboard client. Probably gets calculated based on the HD map and the desired route waypoints with some A*.
In the dataset (measurement.json) and in the transfuser_utils.py "command" is being used. There are 6 categories: [0, 1, 2, 3, 4, 5].
Can anyone help answer some clarifying questions?
Thanks!
