Adult crossing guards normally are assigned where official supervision of elementary school pedestrians is desirable while they cross a public highway on a “suggested route to school,” and at least forty elementary school pedestrians for each of any two hours daily use the crossing while going to or from school. Adult crossing guards may be warranted under the following conditions:
A. At uncontrolled crossings where there is no alternate controlled crossing within six hundred feet, and:
1. In urban areas where the vehicular traffic volume exceeds three hundred fifty in each of any two daily hours during which forty or more school pedestrians cross while going to or from school, or
2. In rural areas where the vehicular traffic volume exceeds three hundred in each of any two daily hours during which thirty or more school pedestrians cross while going to or from school. Whenever the critical approach speed exceeds forty miles per hour, the warrants for rural areas should be applied;
B. At stop sign controlled crossings: Where the vehicular traffic volume on undivided highways of four or more lanes exceeds five hundred per hour during any period when the school pedestrians are going to or from school;
C. At traffic signal-controlled crossings:
1. Where the number of vehicular turning movements through the school crosswalk exceeds three hundred per hour while school pedestrians are going to or from school,
2. Where there are circumstances not normally present at a signalized intersection, such as crosswalks more than eighty feet long with no intermediate refuge, or any abnormally high proportion of large commercial vehicles.
