  • Dataset: BDD

  • format of annotation:

    • video: video id

    • label: contains action and reason for each video

    • action: forward, stop, turn left, turn right, change lane to left('change_left'), change lane to right('change_right'), can't change lane to left('cant_change_left'), can't change lane to right('cant_change_right'), confuse

    • reason: (bool type)

      • forward('f_reason'):

        • follow traffic('f_follow_traffic')
        • road clear('f_road_clear')
        • traffic light is green or yellow ('f_traffic_light')

      • stop('s_reason'):

        • obstacle: car ('s_ob_car')
        • obstacle: pedestrian ('s_ob_ped')
        • obstacle: rider ('s_ob_rider')
        • traffic light is red or yellow ('s_traffic_light')
        • other ('s_other')

      • turn left('l_reason'):

        • front car turning left ('l_front_car')
        • in the left lane ('l_lane')
        • traffic light or sign allows turning left ('l_traffic_light')

      • turn right('r_reason'):

        • front car turning right ('r_front_car')
        • in the right lane ('r_lane')
        • traffic light or sign allows turning right ('r_traffic_light')

      • can't change lane to left('no_l_reason'):

        • cars in the left lane('no_l_car')
        • no left lane('no_l_lane')
        • can't cross solid line('no_l_solid_line')

      • can't change lane to right('no_r_reason'):

        • cars in the left lane('no_r_car')
        • no left lane('no_r_lane')
        • can't cross solid line('no_r_solid_line')
