Closed bottom bus shelters are difficult to keep clean and seem to always have water and trash pooled in the corners. The open bottom glass shelters were designed for ease of maintenance — a truck comes by with a power washer and spends less than a minute to spray it down and clean it. The frameless glass panels are also relatively easy to replace, less parts, less fasteners. The air circulation means they smell better, especially if some inconsiderate smoker decides to use it as a shelter.
