Trial of part time school speed zones

A demonstration project of special speed zoning at six trial sites used manually operated signs and flashing yellow lights to reduce the speed limit during the periods that the supervisor was controling the school crossing. Significant reductions in free vehcile speeds were obtained. Part-time school speed zones which operate at the same times as the school crossing were accepted by drivers with a minimum of enforcement and no specific publicity. Part-time school speed zones are considered to be safe and effective in reducing vehicle speeds at supervised school crossings.
