The general rule for the speaker locations is that the speaker should always be closest to the crosswalk which it signals. If the installer is not aware of the issues and careful to install the devices correctly, they may be installed incorrectly, particularly if the installer is focused on the sidewalk locations rather than the crosswalks. Speakers may not be located on the pedhead that controls the same crosswalk, depending on the pedestrian signal head location. The pedhead closest to one crosswalk may signal the perpendicular crosswalk. In this case, speaker should be mounted on pedhead for perpendicular crosswalk.
