The pedestrian signal heads operate normally, displaying an upraised hand (don't walk) aspect during the time that vehicles have the right of way. [4] When a pedestrian activates the beacon by pushing the pedestrian call button , the HAWK beacon sequence is started.
The MUTCD identifies five types of traffic light mounts. On pedestals, signal heads are mounted on a single pole (this is the normal installation method for the UK). [90] [19] On mast arms, signal heads are mounted on a rigid arm over the road protuding from the pole. On strained poles, signals are suspended over a roadway on a wire, attached ...

For many years these bore white walk and Portland Orange dont walk legends, [ 44 ] but pictograms of an "upraised hand" (symbolizing dont walk ) and a "walking person" (symbolizing walk ) have been required since 2009.

State road rules in the United States usually require a driver to yield the right of way to a pedestrian crossing a road when the pedestrian crosses at a marked crosswalk or an unmarked crosswalk.

This three-arm signal controlled junction has three vehicle phases (A, B and C) and a pedestrian phase (D). The phases operate together in three stages (1, 2 and 3). Moving phases are shown in green and stopped phases are shown in red. Phases are indications shown to traffic on traffic signal aspects (a single light on a signal head). For ...

improve signal conspicuity (to better capture the motorist's attention); increase the likelihood of stopping (with signal head signs, advance-warning flashers or rumble strips); and; address intentional violations (through signal optimisation, properly timed amber-change intervals, and all-red clearance intervals).
