❓ A WA parliamentary question on notice regarding the cost of a trial program for uninterruptible power supplies (UPS) at traffic signals and the estimated cost of installing them at priority sites throughout the metropolitan area. The trial will cost $280,000 and installation at 100 priority sites is estimated at $2 million.

(b) what will be the cost of the trial program; and (c) if installed throughout the metropolitan area, what is the estimated cost?
(c) if installed throughout the metropolitan area, what is the estimated cost?
The Uninterruptible Power Supplies Project will be remotely monitored and controlled and will provide a continuous four hours battery backup power. In the event of loss of mains power the traffic signals will automatically switch to the back up supply so that no loss of service is experienced by the traffic signals. An alarm will be sent advising of the loss of power at the site. Main Roads will monitor the situation and arrange the installation of a backup generator if mains power has not been restored before the battery power supply is exhausted after approximately four hours. (b) The total cost of the trial program including Design and Project Management is estimated to be approximately $280 000. (c) It is not envisaged that UPS systems will be installed at all traffic signal sites. If the trial is successful, it is intended to install them at ?priority? sites on high speed roads, on six lane roads or those with special facilities (ie. linked to railway level crossings). If UPS systems were installed at the approximately 100 priority sites in the State, the estimated cost is expected to be around $2 million, as the economy of scale and improvements arising from the trial are realised. These estimated costs exclude maintenance costs which are unknown at this time.

(a) As part of a pilot trial an Uninterruptible Power Supplies (UPS) Project to develop battery backup systems at busy traffic signals will be installed as a pilot at six traffic signal controlled intersections around the Welshpool area, namely: Tonkin Highway/Leach Highway, Roe Highway/Welshpool Road, Tonkin Highway/Welshpool Road, Roe Highway/Tonkin Highway, Roe Highway/Kalamunda Road and Leach Highway/Welshpool Road. The design of the pilot system is nearing completion, with the field trial expected to commence in October 2004 and to run for 12 months.
The Uninterruptible Power Supplies Project will be remotely monitored and controlled and will provide a continuous four hours battery backup power. In the event of loss of mains power the traffic signals will automatically switch to the back up supply so that no loss of service is experienced by the traffic signals. An alarm will be sent advising of the loss of power at the site. Main Roads will monitor the situation and arrange the installation of a backup generator if mains power has not been restored before the battery power supply is exhausted after approximately four hours.
