Samenvatting

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 ballbank 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.
