Laurence Street has an existing speeding issue, the speed limit on this street is 50km/h and 85 percent of recorded speeds are at about 56km/h so it is important to slow vehicles down at this location for safety.

There is a higher number of vehicles and pedestrians during the weekends as Laurence Street is close to a park and also part of a bus route, therefore, speed cushions can provide a safer road environment on this street.

Feedback

The proposal received positive feedback with some concerns raised by respondents. After reviewing this feedback and all other supporting evidence, the proposal will proceed with changes to the next stage of detailed planning.

Specific feedback

  • Speed limit should be reduced to 40kmph. The road does not meet the requirements for a change in speed limit. Laurence street is designed as a 50km/h speed environment, if vehicles use the road at the appropriate speed the area will be safer for all residents. Changing the speed limit does not necessarily reduce the speed that vehicles travel along this section of road without enforcement.
  • Pedestrian crossing should be installed at the park. The number of pedestrians crossing this area is not high enough to warrant pedestrian crossings at this point. However, with reduced speeds from the speed cushions crossing at the refuge islands should be significantly safer.
  • This will lead to rapid deceleration and acceleration, and noise. The speed cushions along Laurence street were designed to reduce speed over the whole section of road. The spacing was optimised to ensure acceleration between cushions was minimised.
  • Speed limit signage should be installed. As the area is a residential area speed limit signs are considered unnecessary as the standard 50km/h limit applies.
  • Broken yellow lines should be installed on the bridge to ensure vehicles don’t park there. Parking demand is very low on Laurence street and has not been an issue in the past. During the investigation stage no vehicles were parked on the bridge. broken yellow lines are considered unnecessary as residents and locals have plenty of space to park.
  • Will speed cushions slow down buses due to their wide wheel base. The reason speed cushions are being installed it to reduce their effect on bus drivers. Speed cushions do not have a speed calming effect on busses, however, busses drivers should be driving to the speed limit and are monitored by AT Metro.
  • Too many speed cushions / Install more speed cushions / Change the location of speed cushions The speed cushions are designed to standard to ensure that they effective in reducing speed over the whole section of road. The spacing was optimised to ensure a reduction in speed. By removing or changing the spacing we encourage drivers to accelerate between speed cushion increasing noise and reducing the effectiveness of the design.
    Speed cushions have been designed and modelled with vehicle tracking to ensure vehicles can exit and enter side roads without causing damage to the vehicles. This is why moving the cushions closer to the intersection is not an appropriate option.
    An additional speed cushion has been added to the proposal outside 7 Laurence Street as requested by the residents. Speed cushions outside 18 Laurence Street have been moved outside 20 Laurence Street.
  • Traffic chicanes should be installed / Speed camera or Mini Roundabout should be installed at intersection of Cross St, Laurence St. Traffic chicanes were considered during the design process. However, due to the high number of boats and trailers which would have to make these movements it was more appropriate to keep vehicles travelling straight than introduce lateral movements.
    Speed cameras are installed and operated by NZ Police and are installed based on a national programme. Laurence street is considered a minor speeding issue on a national scale and does not warrant speed cameras. The installation and placement of speed cameras has to go through a lengthy process including a committee made up of members from NZTA, NZ Police and the AA.
  • Bus bays should be installed / Why is the bus stop changing location? Currently the bus stop is at the entrance of three driveways. AT Metro is doing improvements on the whole network and has requested that we move this bus stop and improve the facilities.
  • Intersection improvements need to made on Cross St, Give way signs should be installed. If you would like your request to be considered by AT for future development works, please provide feedback here.

Next steps

We expect to introduce this work in the 2018/19 financial year, subject to any further changes in design or funding issues.
Contractors will issue 48-hour notice to all affected residents prior to construction work.
