Wellington bus drivers will have the quality of their driving monitored by new technology, which will keep an eye on poor behaviour such as speeding, harsh braking and rough cornering.
The telematics technology will be installed across its GO Wellington and Valley Flyer fleets, after a successful introduction in Auckland.
The new system would alert drivers when they were approaching the safety or efficiency thresholds NZ Bus had set for particular behaviours.
For each different behaviour a visual signal would start out green, changing to amber when the threshold was being approached and then to red when it was crossed, NZ Bus chief executive Zane Fulljames said.
The system was part of a broader training programme for drivers that would increase their skills and deliver smoother journeys for commuters, while reducing fuel emissions and the physical wear and tear on buses, he said.
