Question NW123 to the Minister of Transport
16 February 2021 - NW123
Lees, Mr RA to ask the Minister of Transport
Whether the Design and Implementation of Speed Humps: Supplement to the National Guidelines for Traffic Calming (details furnished) has been updated since it was last published in 1997; if not, why not; if so, what are the relevant details?
Reply:
The Design and Implementation of Speed Humps: Supplement to the National Guidelines for Traffic Calming has not been updated since it was last published in 1997.
The National Guidelines for Traffic Calming 1998 together with the supplementary documents the ‘Design and Implementation of Speed Humps’ and the ‘Design Guidelines for Mini-roundabouts’ have remained the de facto main national reference documents for traffic calming. Given the holistic approach described in the document, some local authorities had adopted the National Guidelines for Traffic Calming as formal municipal policy as a whole, without any amendment whereas other municipalities opted to develop their own policies and standards for traffic calming.
The National Road Safety Steering Committee (NRSSC) technical committees have updated National Guideline for Traffic Calming measures, including clearer designs for speed humps, as a priority. This updated guideline will be incorporated to Road Safety Authorities guideline manuals for implementation.
