Traffic signal faults

We encourage people to report traffic signal faults or make suggestions for improvements in Whangarei.

To help us help you when you call, please give the operator as much information about the problem as possible.

Information that we will need includes:

  • what the problem is, such as delays/queuing, light bulb not working, or accident damage
  • exact location of the intersection
  • if the problem is queuing or phasing, what time the problem happens
  • the direction of the traffic affected by the problem
  • at pedestrian crossings, which corner or side of the road the push button or tactile pad is not working.

Our traffic signals network

Traffic signals may be installed for the following reasons:

  • there is a safety or traffic flow problems at the existing intersection
  • safety and accessibility considerations require signals control in a new intersection
  • pedestrian and/or cyclist safety will influence the decision to install signals
  • those with disabilities may be impacted by other forms of control.

These reasons are why many intersections within the Central Business District (CBD) operate on traffic signal control.

Why not roundabouts?

  • roundabouts only work well when vehicle traffic flows are balanced and there is little demand for pedestrian or cycle facilities
  • pedestrians find that the gaps they need to cross the road safely tend to be removed by the roundabout's operation. This creates a safety problem for both able-bodied and disabled alike
  • traffic signal controlled intersections resolve this issue by providing safer and more equal opportunity for all road users.

How does the traffic signal system work?

All intersections in Whangarei are connected to a traffic control computer which supervises the whole network's operation.

Traffic volumes are electronically monitored and the computer adjusts the timings at the intersections to manage changes in traffic flows. There are also built-in checks to ensure that time is allocated to maximise efficient traffic flow.

At regular intervals, we review the software and make changes where appropriate.

At various locations intersections are linked together through the traffic control computer to allow the number of stops at intersections to be minimised.
