THE EFFECTIVENESS OF SCHOOL SIGNS WITH FLASHING BEACONS IN REDUCING VEHICLE SPEEDS

The effectiveness of signs with flashers in school zones during times of pedestrian activity in reducing vehicular speed was studied in detail. Individual signs and flashers were examined. Non-uniform signing, inoperative flashers, hidden flashers, deteriorating signs and pavement markers and poor signt distances were found to be problems. Speed measurements were made during flashing and non-flashing periods at 48 locations. Physical characteristics of the locations were taken into consideration. Average speed reductions were only 36 mph (1.6 m/s) during flashing periods. Signs and flashers at high speed locations increased inter-vehicle accident potential because of decreased speed uniformity. Crossing guards caused reduction in speed to within the 25 mph (11-m/s) limit. Speed enforcement, minimal periods of flashing, good sight distance, proper maintenance of signs and flashers, installation only after careful investigation of need, raised speed limits in school zones wherever there is a high speed approach highway and special pedestrian phasing at major intersections are recommended.
