To help bicyclists identify where they should wait at a signalized intersection to be detected by an inductive loop detection system, the standard bicycle detector pavement marking is used, as shown in Figure 9C-7, in the current Manual on Uniform Traffic Control Devices. Previous research has indicated that 55% of the general population does not intuitively understand what this symbol means and as a result do not position themselves over it. Cyclists not properly dwelling over the detection loop will not receive a green indication to proceed through the intersection until another bicycle or automobile arrives at the intersection and stops over the loop, or until someone pushes a pedestrian/bicycle pushbutton. Receiving no green indication results in excessive delay and bicyclist frustration, which is one of many reasons leading to risky red light running behavior. The 9C-7 was always shown first to avoid other designs with more information influencing responses to the marking.
