The Warrant for 40 km/h School Zones (Electronically-Signed Part-Time Speed Limits at Schools)

This conference paper, from the 2002 meeting of the Institution of Professional Engineers New Zealand (IPENZ) Transportation Group, provides a brief description of how the warrant for the installation of 40 km/h school zones was derived from the results of surveys undertaken to evaluate trial sites for these zones in Christchurch, New Zealand. There were trial periods of two years each at five sites in Christchurch. After these trials, the Land Transport Safety Authority (LTSA) implemented a more general installation of 40 km/h school zones. These zones included permanently-displayed fluorescent warning signs, with part-time 40 km/h speed limits imposed by electronically-operated, illuminated signs. The author notes the guidelines for the implementation of a school speed zone, then discusses the "active" nature of the speed limit signs. School zones should only be installed at schools where there is a significant amount of child activity on the roadside, and the times the speed limit signs are activated should align as closely as possible to the times this activity occurs. The author also discusses minimum vehicle speed thresholds, crash history, road classifications, and underlying speed limits.
