New Zealand has adopted the raised-profile type of audio tactile profiled (ATP) roadmarkings. This research was undertaken in 2011/2012 to help address gaps in available international literature on the stability of motorcycles when travelling on or across ATP roadmarkings. The research investigated the stability of motorcycles when contacting ATP roadmarkings, through evidence of traffic crash reports from motorcycle crashes at locations where ATP roadmarkings were present, a review of associated international literature, and simulation of motorcycles interacting with ATP roadmarkings via full-scale physical testing and computer simulation testing. This research found no evidence that ATP roadmarkings as currently used in New Zealand create any significant instability issues for motorcycles. (Author/publisher)
