  • Abstract:
    School speed zones are frequently requested traffic controls for school areas, based on the common belief

    that if the transportation agency would only install a reduced speed limit, then drivers would no longer

    speed through the area. This research project was tasked with reviewing existing practices and developing

    guidelines regarding the establishment of school zones. Researchers documented existing knowledge on

    traffic control devices in school zones using a review of previous research that examined effectiveness of

    devices, a survey of practitioners on signing and marking, a review of state and city school zone guidelines

    and warrants, and a telephone survey of law enforcement officers. Researchers also collected field data at

    24 school zones across Texas and analyzed the data for findings on speed-distance relationships, speed-time

    relationships, influences of various site characteristics on speeds, and special characteristics of school zones

    with buffer zones. The findings from these analyses were used in developing suggested guidelines for

    traffic control devices, including school speed zones, near schools in Texas. The Guidelines are designed to

    serve as a supplement to the Texas Manual on Uniform Traffic Control Devices and the manual on

    Procedures for Establishing Speed Zones. They are included in this report as Appendix A. Major topics in

    the Guidelines include: definitions, school location, school speed zone characteristics, pavement markings,

    crosswalks, school entrances, and conditions for removing a school speed zone.
