The electrical assets include:

  • Street lighting
  • Traffic signals and pedestrian crossings
  • Lighting units for traffic signs
  • Vehicle activated speed limit signs

The Agency manages the electrical assets with the assistance of the Mayrise computerised management system.

The inspection of street lighting includes night patrols to identify lamps which are out or obscured by trees, structural testing and electrical testing.

Area identified for improvement or renewals are included in the programme for future works and bids for funding submitted accordingly.

To minimise the number of lamp failures a bulk change is carried out at a frequency determined by the life expectancy of the lamps used.
This may be annual, or every two or three years. In addition, the fittings are cleaned on an annual basis.

The traffic signal equipment used on the network is expected to operate without regular routine adjustments. Inspections are carried out to identify defects which may lead to failure at a later date.

Most of the signal installations are now equipped with remote monitoring facilities enabling faults to be detected without the need to visit the site.
