Adult Crossing Guards

Introduction
Adult Crossing Guards are an additional measure to assist elementary school pedestrians and are not a traffic control device. They may be assigned to designated school crossings to assist elementary school pedestrians at specified hours when going to or from school. The following suggested policy for their assignment applies only to crossings serving elementary school pedestrians on the "Suggested Route to School".

An Adult Crossing Guard should be considered when:
  • Special problems exist which make it necessary to assist elementary school pedestrians in crossing the street, such as at an unusually complicated intersection with frequent turning movements and high vehicular speeds; or,
  • A change in the school crossing location is pending but existing conditions require school crossing supervision for a limited time and it is impossible to install another form of control for a temporary period.
Need for Adult Crossing Guards
Adult Crossing Guards normally are assigned where official supervision of elementary school pedestrians is desirable while they cross a public highway on the "Suggested Route to School", and at least 40 elementary school pedestrians for
each of any 2 hours daily use the crossing while going to or from school. Adult crossing guards may be used under the following conditions:
  • At uncontrolled crossings where there is no alternate controlled crossing within 600 feet
    • In urban areas where the vehicular traffic volume exceeds 350 during each of any 2 hours (not necessarily consecutive) in which 40 or more school pedestrians cross daily while going to or from school
    • In rural areas where the vehicular traffic volume exceeds 300 during each of any 2 hours (not necessarily consecutive) in which 30 or more school pedestrians cross daily while going to or from school.
    • Whenever the critical approach speed (85 percentile) exceeds 40 mph, the guidelines for rural areas should be applied.
  • At stop sign controlled crossings:
    • Where the vehicular traffic volume on undivided highways of 4 or more lanes exceeds 500 per hour during any period when the elementary school pedestrians are going to or from school.
  • At traffic signal controlled crossings:
    • Where the number of vehicular turning movements through the school crosswalk exceeds 300 per hour while school pedestrians are going to or from school
    • Where there are  situations not normally present at a signalized intersection, such as crosswalks more than 80 feet long with no pedestrian protection, or high  amount of large commercial vehicles.
