These already happen to be implemented in Toronto as bike corrals which take up the length of just under two car parking spots. They are removed for snowy seasons and reinstalled in the spring.
FWIW, I feel more confident in parking my bicycle in these corrals than I probably would if parking on the platform featured in the link, as the bike corral is protected on the three sides facing the road.
