The Bleep and Sweep
signal which was developed for the Highways Agency in
collaboration with Southampton University’s Institution
of sound and Vibration Research, has a sound which is
quite distinctive from other traffic noises. It also
has the ability to adjust its volume according to ambient
noise levels so that in busy city streets it will be
much louder than for example, in a quiet residential
area.
This means that during the off peak hours when traffic
volume is low the disruption to local residents is kept
to a minimum thus ensuring that it is environmentally
friendly.
Fully interlocked for safety
– audio and tactile signals will only appear
when all the following combinations are present
and correctly timed;
Green ‘clear to cross’ is on
Interlock signal (Red to traffic) is on
Red ‘do not cross’ is off
