(Amended by Ord. No. 134,523, Eff. 7/17/67.)
(a) The Department is hereby authorized to determine those streets, intersections, or highway railroad grade crossings at which there is a special hazard to life or property by reason of the volume of traffic upon such streets or at such intersections, or over such highway railroad grade crossings, or because of the lack of visibility to the drivers of vehicles approaching such streets, intersections or highway railroad grade crossings, or because of the number of reported accidents or the apparent probability thereof, or by reason of physical conditions which render any such streets, intersections or highway railroad grade crossings exceptionally dangerous or hazardous to life or property, and where the factors creating the special hazard are such that, according to the principles and experience of traffic engineering, the installation of stop signs is reasonably calculated to reduce the expectancy of accidents, and that the use of warning signs would be inadequate.
(b) When such determination has been made, the Department shall designate any such street as a through street between specified limits, or designate any such intersection as a stop intersection, or designate any such highway railroad grade crossing as a Stop Railroad Grade Crossing, subject to the approval of the Public Utilities Commission of the State pursuant to the provisions of Section 21110 of the Vehicle Code, and the Department shall post such stop signs as are necessary to give effect to such designation. Stop signs at any intersection may be so posted so as to stop either or any of the streams of traffic entering such intersection as the needs of the particular location may require.
