School zone is a stretch of a road or a street proximate to a school and as such is designated by proper traffic signs. Transparent marking of school zone alerts drivers to be especially careful while driving through such designated area in school zones, where children are frequently pedestrians, traffic calming measures include not only traffic signs for speed limits, but also different kinds of obstacles and vibro lines- sound warning devices. In addition to the above measures in school zone vehicle speed detector with display can be implemented as additional warning for drivers in case of speeding. The vehicle speed detectors with displays are set on approaches to the school from both sides, and the devices operate on the principle of variable message signs and radar speed detection of the encountered vehicle and it's speed appears on the display. The speed of the vehicle is displayed continously thus enabling to monitor how the driver behaves, or whether he reduces or increases the speed of his vehicle. If the speed is above that allowed for the school zone, a second display with messages alerts the driver of speeding and informs him that he is driving through the school zone. In this paper, vehicle speed detector with display in school zone implementation is analyzed in highly urbanized areas and on stretches of main roads passing through rural areas.
