We are responsible for 318 traffic signal installations.
This includes:
- 158 signalled junctions
- 123 signals at pedestrian crossings (Pelican and Puffin)
- 36 signals at pedestrian and cycle crossings (Toucan)
- 1 equestrian crossing (Pegasus).
In addition, we manage assets associated with the following:
- the Urban Traffic Management and Control System
- the Canwick Road Tidal Flow system
- traffic signal matrix signs
- bus priority facilities
- fixed and portable CCTV cameras
- the Fire Service Green Wave priority equipment
Most of our sites have been upgraded to use ELV LED signal heads to improve reliability and reduce energy consumption.
Inspections and maintenance
Every year each installation will be inspected. This includes the physical condition of the controller, auxiliary equipment cabinets and other site hardware like poles and signal heads. We also carry out earth testing and clean the signal lenses.
In addition, every 6 years, a full inspection for electrical safety is carried out.
Reactive maintenance
Our contractor Colas looks after our traffic signals. Standard contract hours are 07.30 – 18.00, Monday to Friday, with emergency cover provided at weekends.
Response times for attending a fault are:
- Standard faults (e.g. lamp failure, detector fault) – 12 hours
- Emergency faults (e.g. signals all off) - 2 hours
Fault attendance times and repairs are a crucial activity within the contract and are monitored and assessed through our Fault Management System.
Planned maintenance
We keep comprehensive records of our traffic signals assets and their maintenance. This enables us to plan maintenance and refurbishment works at the optimal time when the assets are close to the end of their serviceable life.
We recognise that traffic signals work can be disruptive and work hard to keep this to a minimum. We try to coordinate our works with other highways maintenance like planned resurfacing.
In the next 5 years, we have planned refurbishment works at 41 sites.
