MOXHAM / HATAITAI / WAITOA INTERSECTION

ROUNDABOUT PROPOSAL

Hataitai Residents Association

7 July 2020

Summary

• The majority of bus passengers travelling from the eastern suburbs to the central city travel

through the intersection. It is used by approximately 7,000 people in buses and 12,000 people in

private vehicles per day

• A number of reported crashes and near misses, one involving a mother and baby, at the Hataitai

intersection at Hataitai Road, Waitoa Road and Moxham Avenue have been received over recent

years.

• Concerns were raised by the community regarding pedestrian safety and driver confusion at this

intersection through the Residents Association.

• Previous engagement with the community on the proposal of traffic lights in September 2018

met objections and a number of other options have since been explored.

• When ranked against criteria the delivery of a small mountable roundabout with a raised zebra

crossing on the Hataitai Road approach was considered to deliver the maximum benefit of

overall performance and pedestrian safety at this intersection.

2

Previous engagement on traffic light proposal

• In September 2018, we consulted with the local community on a proposal to install traffic lights at the

intersection to improve safety, particularly for pedestrians.

• We had great engagement on this proposal, with nearly 800 people, businesses and organisations taking

the time to provide a submission, 82% of these being residents.

• While more than half of respondents answered ‘YES’ to having experienced, witnessing or being aware of

crashes or near misses at the intersection, only 32% supported the installation of traffic lights.

• We concluded that based on a high percentage of concerns received regarding the safety at the

intersection, there was a definite mandate to make safety improvements, but not for traffic lights.

• Since then our Council officers have assessed various other options (15 in total) and a roundabout is now

being proposed.

How options performed

7

• A cost benefit analysis has been carried out with three options considered: a roundabout, traffic signals

with parallel and Barnes dance crossings, and the current road layout. The roundabout option has shown

significant benefits and a far safer and more efficient design that what is currently in place.

• The roundabout option offers travel time benefits for private vehicle and bus passengers, with only a slight

increase in travel time for pedestrians – between 10 and 14 metres which equates to between 8-12 seconds

per pedestrian journey when using a zebra crossing compared with the current direct route.

• The roundabout option has the only true cost benefit ratio and provides high value for money, in the order

of $3 million compared with an indicated $1.5 million dis-benefit on the traffic signal proposal (based on

NZTA’s 40 year analysis period).

Parking & Place Function

• A total of 13 car parks will be removed with the Roundabout proposal, however we are looking at opportunities

to create further parking around the vicinity of the intersection.

• Bus stop on Hataitai Road (Hataitai Stop C) – GWRC have advised us that this bus stop can become part-

time as it is only used in the morning peak hour. It is proposed that this bus stop operates from 6.30am-

9.00am and P60 At All Other Times. This would free up 3 spaces in this location.

• Change unlimited angle parking on William Street to P60 (3 to 6 spaces).

• Bus Stop on Waitoa Road East (Hataitai Stop E) – possible option to re-instate some parking pending on

GWRC’s new timetable changes assessment.

• Place function is currently being investigated at the intersection.

Communication Approach

• WCC initially consulted with the whole community with a proposal for traffic lights, and received strong

engagement with approximately 800 responses.

• We are now taking a slightly more targeted approach with the proposal for the mountable roundabout.

We are now talking mainly with Ward Councillors, the Resident’s Association, Hataitai businesses and

those who made submissions in the previous engagement in 2018.

• The communication is now focused on the preferred option of a mountable roundabout with a raised

pedestrian crossing (on Hataitai Road) and building community support for this - a full communications

plan in is place.

• A Traffic Resolution will be required to legalise the parking changes and a formal consultation targeted at

those residents and business most affected will be required.

Our investigation into a mountable roundabout saw that there would be moderate and significant improvements to each aspect we looked at. Pedestrian safety and vehicle efficiency are projected to see moderate improvements and

driver confusion indicates that it will be significantly reduced. With this option we will see a safer area for pedestrians and cyclists in comparison to the current situation, which falls into WCC’s Transport Strategy, where we are aiming to

create less demand for individual car usage, and enhance the experience of public transport, cycling and walking. $125k

This involves lifting the road level at the intersection to slow traffic and enhance the village centre. There would be moderate improvements to place function and a slight improvement for pedestrian safety. Other factors would see no

significant change. $200K

This involves installing traffic lights to control all movements at the junction. Pedestrians would be given an early start before turning vehicles are allowed to filter through the pedestrian crossing and give way to the people still on the

crossings. The pedestrian signalised crossings would be placed on the desire line of the pedestrians to achieve greater compliance and safety for all intersection users. $250k

This involves leaving the crossings in their current positions, but making them more visible by lengthening the white bars and highlighting them with a coloured background. Pedestrian guide tactiles would also be installed on all

approaches to assist visually impaired users. There would be little to no changes to the cur- rent situation. $30k

This is a bigger version of the raised intersection. It involves reconstructing all the roads in the village centre to create a large shared area similar to lower Cuba Street. A lower speed limit (10km/h) would be appropriate to reinforce the

shared nature of the streetscape. The only change from this option was slight improvement in overall safety. $1.5milliion

This involves changing the Give Ways to Stops, extending the kerbs and relocating the pedestrian zebra crossings further away from the intersection to make it clearer to motorists which approaches have right of way. We would be

expected to see slight changes to the current situation, in both positive and negative ways, however overall it would remain the same. $120k

Comparison between mountable roundabout and traffic signals and existing road layout

• A cost benefit analysis has been carried out with three options considered; traffic signals with parallel and

Barnes dance crossings and the roundabout with average delays on each intersection approach and

estimated average delays for each pedestrian crossing leg between 5.00pm -6.00pm.

• The roundabout option substantially decreases delays on all four approaches. All three options increase

pedestrian delay with signals with the Barnes Dance being the worst performing.
