All such installations shall be in accordance with the standards that may be set forth in this chapter or by ordinance or resolution of the City Council.

D.    Emergency and Experimental Regulation. Notwithstanding any other provisions of this chapter, when it is reasonably necessary to facilitate the movement of traffic and prevent pedestrian and vehicular congestion of the City streets, the City Traffic Engineer is authorized to establish emergency and experimental regulations to control the direction and movement of traffic, including establishing one-way streets, changing the direction of travel on one-way streets otherwise established, and installing and maintaining signals, signs and other devices to indicate the regulations so established.
