Sim_Agent: issue with off_road metric

[YueYao-bot]

Dear Waymo team,

I notice that when you calculate the distance between agent and road edges, this function (

waymo-open-dataset/src/waymo_open_dataset/wdl_limited/sim_agents_metrics/map_metric_features.py

Line 112 in 5f8a1cd

corner_distance_to_road_edge = _compute_signed_distance_to_polylines(

) could return negative value, which is always lower than the threshould of "off road".

Best regards,

Yue

okay, seems I wasn't understand it correctly. The OFFROAD_DISTANCE_THRESHOLD=0, which means "in road" should have a negative value.

The problem is: I tried to set the all states of object trajectory to 0, which clearly out of the area of map. The distance to road_edge is something like -10000. However, it is lower than the threshould and considered as "in road".
