When it has been determined upon the basis of an engineering and traffic survey that a speed greater than the prima facie speed limit of twenty-five miles per hour would facilitate the orderly movement of vehicular traffic and would be reasonable and safe under the conditions found to exist upon any street or highway in the city, the city council may by resolution determine and declare a prima facie speed limit of thirty, thirtyfive, forty, forty-five, fifty, fifty-five or sixty miles per hour or a maximum speed limit of sixty-five miles per hour, and such declared prima facie speed limit shall become effective when signs are erected giving notice thereof.
