摘要：	School zones are often viewed as an effective way to reduce driving speeds and thereby improve safety near our nations 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.
