Ok, thank you very much !
I think these information is very important for trajectory prediction project !

Hi, @lucabergamini , I feel confused too, as paper says, you provide these property in semantic_map:
Lane boundaries
Lane connectivity
Driving directions
Road class
Speed limits
Lane restrictions
Crosswalks
Traffic lights
Traffic signs
Restrictions
Speed bumps
but the map_dict_keys only have lat, lon, lanes, lanes_bounds, crosswalks, crosswalks_bounds.
I look into lanes[0], I get this result:

What's the meaning of each array ?
I'm looking forward to your reply !
Thank you!

Hi @la1290 @pch9520, thanks for the feedback!
Is there any way getting the lane connectivity and driving directions from the semantic map?
Not yet from our API, but that information is in our semantic map proto, so it will be exported in the future.
I feel confused too, as paper says, you provide these property in semantic_map
All those features are in the map proto and we're working hard to provide API user will be able to include in their projects to use those features
What's the meaning of each array ?
please take a look here for the exact syntax of the arrays. lanes
elements have the following shape:
- left-boundary tuple
- X coords np.array
- Y coords np.array
- Z coords np.array
- right-boundary tuple
- X coords np.array
- Y coords np.array
- Z coords np.array
We're planning to expand the semantic rasterisation and API with tons of features in the upcoming months
from l5kit.
Lane boundaries Lane connectivity Driving directions Road class Speed limits Lane restrictions Crosswalks Traffic lights Traffic signs Restrictions Speed bumps
I am looking into these too. Can you please let me know how I can get these information? Basically, we plan not to use images at all. But, rely on low dimensional road geometry information and semantic map information. I was looking into https://github.com/lyft/l5kit/blob/20ab033c01610d711c3d36e1963ecec86e8b85b6/l5kit/l5kit/data/proto/road_network.proto . But, I really do not know how I can correlate scenes with this.
Also, how is l5kit.data.load_semantic_map
different from l5kit.data.map.load_semantic_map
? I am not able to use either.
