Technical Note - Curve Advisory Speeds in New Zealand (2002)
AuthorsKoorey, Glenshow all
Recent research investigated the use of curve advisory speed signs in New Zealand. A comprehensive literature review identified key issues to examine. Current traffic speed behaviour was observed at the site of curve advisory speed signs, using a series of optical sensors, in order to determine effectiveness and compliance. Alternative methods for determining curve advisory speeds, using road geometry data or accelerometer/gyro-based systems, were compared with ball-bank surveys. The existing criteria and methods used for setting curve advisory speeds in New Zealand were assessed in light of the above findings, and changes suggested.
