How does traffic detection system work?

[EcotronCorp]

1)Run the traffic light detection program, /rough/rois and /rois topics have values, and rviz 2) Displays the result as unknown, which is affected by the judgment condition in the traffic_light_map_based_detector node. Why is the green frame drawn when approaching the traffic light or when the vehicle has already passed the traffic light?;

@yukkysaito @shmpwk Could you answer this question ? (This is likely a bug in traffic light recognition module or awsim 🤔 )

Could you share your environment? (map, SVLSimulator model…)
It looks the position of the traffic light is different from the lanelet map and SVLSimulator. The traffic light 2523 shows right side on the lanelet map, but shows left side on the SVLSimulator.
