Rotorua, New Zealand: IPENZ Transportation Group Technical Conference 2002, 25 Sep 2002. 5 p.http://hdl.handle.net/10092/634Recent 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.enConference Contributions - PublishedFields of Research::290000 Engineering and Technology::290800 Civil Engineering::290803 Transport engineering
