This is something we get asked for a lot in Stoke by the public as they 
see=
m to
think it is a legal requirement for us to provide a temporary crossing 
faci=
lity
at roadworks where a permanent crossing has to be switched off so I did 
some
research into it.

This is taken from LTN 1/98 "The Installation of Traffic Signals and 
Associ=
ated
Equipment":

8.09   Care should be taken to safeguard pedestrian safety during 
roadworks
   within the area of the work site and particularly at or near pedestrian
 =20 crossing facilities.     Temporary pedestrian facilities may be 
provid=
ed on
    temporary signals as long as the area where pedestrians should cross 
is
    clearly marked.

This suggests that pedestrian facilities could be used at temporary 
signals
when working near a pedestrian crossing which has to be switched off.

The actual brochure for the product says that it is fully compliant with 
TR=
2503
"Performance Specification for Pedestrian Facilities at
Temporary Stand-alone Traffic Signals". (This=20can be found at the TSS 
pla=
ns
registry website: http://www.tssplansregistry.org )

This specification states that the product should comply with TSRGD 
Diagram
3000, Regulation 33, the signals shall comply with TSRGD Diagram 4002.1,
Regulation 47, and=20the push button shall comply with TSRGD Diagram 4003=
 and
Regulation 47.
The unit uses peak elite signal heads and AGD push button units all of 
which
are fully compliant with the TSRGD regulations.

With regards to approval for the product as a whole,=20this comes under 
the
requirements for Self-Certification set out in TRG 0600 (http://www.
tssplansregistry.org) which allows companies to design, test and self 
certi=
fy a
product to a specific Technical Requirements Specification. This 
specificat=
ion
also gives regulations that it must be compliant with when using radio 
sign=
als.
Again in the brochure this is something that the company states the 
equipme=
nt
fully complies with and so I believe the product could legally be placed 
on=
 the
highway with no site specific authorisation being required.

The one thing that would be of interest is how drivers react to the 
signals.
Drivers tend not to treat temporary signals with the same respect as 
perman=
ent
ones and so when they see the other side stop they may drive through the 
red
signal which would create a major safety issue.
