The

2011 Texas Manual on Uniform Traffic Control Devices

(TMUTCD) includes the Pedestrian Hybrid Beacons (PHB) for use at marked crosswalks which are not managed by a traffic control device such as a traffic signal or stop signs.

A PHB is a pedestrian-activated warning device located on the roadside, or on mast arms over midblock pedestrian crossings. The beacon head consists of two red lenses above a single yellow lens. The beacon head is dark until the pedestrian wanting to cross the roadway presses the button and activates the beacons.

This device provides an additional tool for improving the safety of crosswalks when traffic signals do not meet warrants. PHB's should be used in conjunction with signs and pavement markings to warn and control traffic at locations where pedestrians enter or cross a street or highway.
