Faulty traffic light data in mini db - Vehicle drives over red traffic lights #329

Hello,

first of all, great work on the devkit! It makes working with the databases much easier :)

During working on my own visualization for the mini db files, I encountered some strange driving behavior. It seems like the vehicle drives over two red traffic lights (lane_connector_ids 18456 and 20246) as if they didn't exist. Can you tell me the reason for that? Am I overlooking something? Thanks in advance!

Hello,

the traffic light data is inferred from the movement of the vehicles in the scene (e.g. described here). I assume this causes occasional errors in the traffic light data provided to the planner. However, I observed these errors rarely in practice. Maybe there will be improvements to traffic light data in the future. I don't know if that's planned by the nuPlan-team.

Best, Daniel
