B. The city traffic engineer shall ascertain and determine the locations where such signals are required by resort to field observation, traffic counts and other traffic information as may be pertinent and his determinations therefrom shall be made in accordance with those traffic engineering and safety standards and instructions set forth in the California Maintenance Manual issued by the Division of Highways of the State Department of Transportation.

C. Whenever the city traffic engineer installs and maintains an official traffic signal at any intersection, he shall likewise erect and maintain at such intersection street name signs visible to the principal flow of traffic unless such street name signs have previously been placed and are maintained at any said intersection.
