I may be missing something here, but surely you just need a new
('permanent-type') controller equipped with elv outputs (Microsense and
Peek both do this as I understand it), which will come with all
functionality including UTC interface (as specified). If you install this
on a short term basis - surely it becomes 'temporary'!

[TCUG] Re: FW: TCUG query
This subject has been bouncing around for years!!
I would imagine that the first requirement is to look at the legal
requirements for temporary signals (conflicts, detection etc.) and then
apply them to the semi permanent arrangement, hopefully any permanent
controller post 0141 would supercede these requirements! I would imagine
it
would be pretty easy to get a "bombproof" controller (T200, 400) which is
easy to build up or down to the required configuration. (other controllers
are available) If there is a requirement for 50-0-50 supply, then I
believe
most controllers were available to Welsh Office Spec or possibly Hong Kong
which had this as a requirement. I've never understood why temps could not
be controlled under UTC as long as the controller and interface were
approved for use, which in this case, they would be. I would look no
further
than TfLs stockpile of controllers and build various configurations to
suit,
based on the existing MOC.

Alan.
Thank you for your response.
As I understand it, portables have limited capability and features. What
we
are attempting to do is develop a temporary/portable controller that can
provide the full range of phases/stages and detection as the existing site
controller that may have been knocked down or is being replaced under
modernisation.
The key issue is that we want to maintain the network capacity through the
period that the work is taking place.
Best regards,
Jag

Jag - in Blackpool we use portable signals for such situations - these are
provided and managed by a local traffic management company.
In the event of a knock-down we can usually have portable signal control
within 1 hour - if its a large junction then we reduce the traffic lanes
with signing and coning - obviously this causes delays but at least the
junction is safely controlled.
We also successfully used portables at various stages of junction
modernisation / improvements.
With the advent of the new radio controlled portables there is no longer
the
need for extensive cabling and cable mats
