All_Aboard (IMAGE)
Caption
(A) Typical MBTA bus stop signs among the selected trial locations in downtown Boston. Very few bus stops in the area covered by the transit agency are sheltered, and the distinctive sign is often the only visual identification of the bus stop. (B) Operation of the All_Aboard app in the general vicinity of a bus stop. The lower inset shows the app detecting the bus stop sign (the bounding box is drawn around the detected sign in the camera view displayed on the smartphone screen). The percentage value around the bounding box indicates the confidence of detection. The upper inset shows a successful detection at night in low light conditions.
