Abstract:

This research studied the relationship between removal methods used to remove pavement markings and driver confusion when encountering ghost lines. The study included field based and driver video experiments. Video data was collected at five locations in Oregon to examine the frequency with which drivers did not follow the correct markings when encountering ghost lines. The 40 participants video experiment was used to determine which removal method affected drivers’ perception of which markings were the correct ones to follow. Hydroblasting was found to be the method that participants most frequently looked at when encountering the removed pavement markings versus the grinding method in all weather and lighting conditions. The study results suggest that the hydroblasting method should be used in conjunction with restriping methods that ensure that the correct pavement markings are followed.
