Technology that allows late buses to get priority at traffic lights is be rolled out to more Auckland intersections.
An Auckland Transport promotional video said it used a buses' onboard GPS to identify when a service was running late.
They could then prioritise green traffic lights on the buses' route to give it a "green wave" or "boost" to get it back on time.
"If you can speed up more people hopefully public transport becomes more attractive" - Auckland councillor Richard Hills
Auckland councillor Richard Hills said the technology was trialled on Manukau and Dominion Roads and the Eastern Busway last year.
It would be added to 25 more intersections over the next six to eight months, he told Morning Report.
"Essentially it's trying to speed up the public transport system so people want to use buses more. There's nothing worse than being in a bus stuck behind 10 cars when there's 90 of you in a double decker waiting to get through a queue."
Hills said there had to be a bus lane, or another mechanism to give buses priority, for the system to work.
"If we want to add more of them in areas where we don't have bus priority, we will have to add things like bus lanes and transit lanes, which someone people don't like. But we know that if you can speed up more people hopefully public transport becomes more attractive which speeds up everyone."
