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
