The state traffic laws regulating the speed of vehicles shall be applicable upon all streets within the city, except as otherwise provided by ordinance upon the basis of engineering and traffic investigation that certain speed regulations shall be applicable upon specified streets in certain areas. Any speed in excess of the speed so declared by ordinance, when signs are in place giving notice thereof, is prima facie evidence that the speed is too great and therefore unreasonable.
