This study investigates the influence of 15 line marking types on cycle instability. Six paid participants completed more than one thousand runs over test lines using the same instrumented racing cycle. Recordings of lateral acceleration and handle bar angle were combined to form a single measure of instability relative to recordings of normal riding over smooth asphalt. New techniques to control for learning effects were used within an experimental procedure that controlled for the angle and speed of the cyclist. Findings compare the influence of line markings such as audio tactile lines, new structured markings, thermoplastic markings and traditional waterborne markings. Oversized thermoplastic lines (7mm thick) and audio tactile lines showed significant effects on the stability of cycles whereas traditional chlorinated rubber lines and waterborne line showed no significant impact on cycling.
