    • Abstract:
      School zones are often viewed as an effective way to reduce driving speeds and thereby improve

      safety near our nation’s schools. The effect of school zones on reducing driving speeds, however, is

      minimal at best. Studies have shown that over 90% of drivers exceed speed limits posted in school

      zones (Trinkaus, 1996; Trinkaus, 1998). Many drivers report that their lack of speed reduction was

      based on the fact that they were unaware that they were in a school zone (Ash, 2006).

      Researchers have investigated methods used to increase driver compliance for some time (McCoy,

      Mohaddes, & Haden, 1981). Based on the results of empirical studies, effective methods include

      increased enforcement (Dumbaugh & Frank, 2007), appropriate speed zone settings (Day, 2007;

      McCoy & Heimann, 1990), visual placement of school buildings and play equipment (Clifton &

      Kreamer-Fults, 2007), and speed monitoring devices (Ash, 2006; Lee et. al., 2006). In a recent study,

      Kattan, et al., (2011) found that in the situation when there is 2-lane roads, roads with fencing, traffic

      control devices and the presence of speed display device or children, and zones that were longer,

      drivers’ mean speed was lower and the rate of compliance was higher.
