2.Evaluate (analyze) intersection

The next step is to really evaluate and analyze the intersection by listening first to determine traffic patterns and intersection geometry. The pedestrian who is blind needs to stand there and listen through a signal cycle to attempt to figure out the number of lanes, direction to cross and other information about the intersection that can be discerned by listening. During that time, pedestrians also should listen for a pushbutton locator tone or a tone or speech walk indication that would let them know that there are APS installed at the intersection.

The next question is to determine if the WALK indication is audible on every cycle. If so, it’s probably pretimed and it may not be necessary to push a button for a walk interval , although APS devices may include a tactile arrow or other information. If pushing the button is not needed, it may be that the preference is just to listen through a cycle to confirm sounds and the street signaled. Some individuals may prefer to find the pushbutton and check the arrow and vibrotactile indications.
