Install no U-turn sign on Wood street

Ubers making 3-point turns on Wood Street to avoid going through Mutual Street (one way) - potentially hitting pedestrians and more importantly children

I realize that any traffic rule violations taking place on the road should be reported to Toronto Police: 416-808-2222. However, when I reported my concern they said that they had to catch them while the infraction was taking place, saying that there has been no patrol of Wood Street to catch such infractions. 

I believe it would be beneficial to install a no U-turn sign on Wood Street) for improving the safety at this location
