The zones use electronic signs to temporarily lower speed limits when a vehicle approaches from a side road to reduce crash risks.
Temporarily reducing speeds to 60km/h at intersections when an approaching car is detected increases road users’ awareness and gives them more time to react to avoid collisions, the agency said.
If a crash did happen, it would be less likely to result in serious injury or death.
“They don’t completely prevent crashes, but research shows they do help to mitigate the risk of them occurring and the severity when they do,” NZTA director of regional relationships Waikato Bay of Plenty, Andrew Corkill, said.
Several of the intersection speed zones have already been implemented in these regions following public feedback, with positive results, NZTA said.
Corkill said the consultation, held across the next six weeks, will welcome all official submissions.
“Along with safety, technical, cost, benefit and other data, community feedback is a part of the process we can’t do without when determining whether we should change speed limits in these locations.
“Local and road-user insights are invaluable.”
Speed limits under review
The proposal is to permanently change the speed limit from 80km/h to 60km/h east of Quarry Rd to south of the Whangapoua Rd intersection.
The proposal is to permanently change the speed limit from 80km/h to 60km/h west of Hot Water Beach Rd to east of Hot Water Beach Rd.
The proposal is to install an intersection speed zone to take the speed limit from 80km/h to 60km/h when the electronic sign is activated for a short time.
There are proposals for various permanent speed limit changes.
There are proposals to permanently change speed limits on several sections of these state highways.
The proposal is to permanently change the speed limit from 70km/h to 50km/h north of Bellot St to south of McClure St.
The proposal is to permanently change the speed limit on a section of the state highway at the entrance to Te Kūiti south from 100km/h to 50km/h.
The proposal is to remove the intersection speed zone as it is no longer required following the construction of the roundabout.
The proposal is to permanently change the speed limit from 70km/h to 60km/h east of Cambridge Rd to west of Cambridge Rd.
The proposal is to install an intersection speed zone to take the speed limit from 100km/h to 60km/h when the electronic sign is activated for a short time.
The proposal is to remove the variable speed limit as the school entrance has been moved off the state highway and the variable speed limit is no longer needed.
More information about each proposal and the online survey is available on the NZTA website.
The survey is open until 5pm on August 27.
