Speed monitoring displays (SMDs) were installed in four reduced speed school zones in Utah in order to evaluate the effectiveness of these dynamic signs at improving speed compliance. Despite the data loss due to the malfunctions of the SMDs and speed data collection equipment, substantial speed data were collected, analyzed, and compared from before and after the SMDs were installed. In some cases the SMDs maintained their effectiveness at increasing speed compliance; in other cases they lost some of their effectiveness possibly due to higher percentages of commuter traffic. For the most part, these SMDs helped improve school zone safety by decreasing speeds and increasing speed compliance as manifested by the decrease in mean speed, standard deviation, 10 mph pace range and the percentage of vehicles exceeding the 20 mph school-zone speed limit.
