Lees Road Carpark Entrance - Options Report 3

1 Introduction

It is understood that Thames-Coromandel District Council (Council) are constructing a new car park

on Lees Road in Hahei at approximately RP 1450. The car park is predicted to fit approximately 500

cars. Due to the anticipated increased traffic along Lees Road and into the car park, Council is seeking

options to treat the entranceway to the car park to ensure that through traffic remains relatively

unaffected, that visitors are adequately directed to and into the carpark without travelling further up

Lees Road and visitor traffic can enter and exit the car park safely. Opus have been engaged by

Council to investigate treatment options for the entrance to the car park as listed below:

• Option 1: Provide a right turn bay on Lees Road into the car park;

• Option 2: Provide a rural T-Intersection;

• Option 3: Provide a 4m radius central island roundabout.

• Option 4: Provide a 10m radius central island roundabout.

It should be noted that Opus has also been engaged to undertake a seal extension design for Lees

Road from RP 0 to RP1620. Works that are to be undertaken as part of the seal extension have

been omitted from this investigation.

2 Existing Infrastructure

2.1 Site Location

Figure 1 shows the proposed location of the car park entrance site, at approximately RP 1450 on Lees

Road in Hahei.

Proposed car

park entrance


2.2 Existing Road

The existing section of road where the car park entrance is proposed is currently unsealed, consisting

of a carriageway width between 5-6m, with no centreline or edgeline markings. It is our

understanding that this section of Lees Rd from Hahei Road to the existing sealed section of Lees

Road is proposed to be sealed prior to the carpark being commissioned, it is expected that the sealed

width of Lees Rd will be 7m from Hahei Rd to the carpark entrance.

Lees Road has no signed speed limit, however rural roads generally have a posted speed limit of

100km/h. The estimated design speed for the 2 curves either side of the proposed car park entrance

are 45km/h and 55km/h in the direction of Lees Road from Hahei Road.

Lees Road is generally constructed within the road reserve, however it appears that some parts of

Lees Road may be within private property, including a small section to the north of the proposed car

park entrance as can be seen on the image below.

The site of the proposed car park entrance is moderately flat. Lees Road winds towards the north

west direction in front of the proposed car park entrance.

The carpark entrance is to be shared with a private land owner who requires access into their private

farm property via the same car park entrance. Other stakeholders to be considered are the property

owners and business owners further north on Lees Road, some of which are driven by tourist trade.

3 Option 1: Right Turn Bay

Figure 2 shows the concept sketch for Option 1: Right Turn Bay. Refer to Appendix A for a higher

resolution sketch.

Figure 2: Option 1: Right Turn Bay

The following works are proposed for this option:

• Widening of the proposed sealed road by approximately 5.5m to allow for a right turn bay in the north direction on Lees Road. The right turn bay will provide an exclusive area for traffic turning right into the car park to stand until the way is clear to make the turn safely. There will be room for several vehicles to stack waiting to make the right hand turn.

• This treatment is an accepted and expected treatment for motorists travelling on a rural

road of this nature.

• Pavement marking including:


o Centre lines and edge lines to delineate traffic lanes; o Limit lines to guide traffic to slow down/stop; o A give way symbol; o A chevron painted median to allow traffic into the right turn bay.

• Installation of new signage including: o Give Way signage; o Headway Chevron signage.

• Installation of lighting at the intersection to illuminate and provide visibility at night.

This option will have the least disruption on existing vehicle movements along Lees Road during

construction as the widening from the existing road can be constructed offline, allowing 2 lanes of

traffic to remain open. The extra width also means that 2 lanes of traffic can be maintained during

other works throughout the project such as sealing and line marking.

A small section of the proposed road on the northern side of Lees Road crosses into the adjacent

property, this is an existing situation. This is the same property that the car park is being constructed

on therefore land acquisition to formalise the area being used as road could be a simple procedure.

Alternatively Lees Road could be widened and realigned to the south within the existing road reserve.

This option will provide vehicles waiting to turn right into the proposed car park approximately 85m

of Safe Intersection Sight Distance (SISD) with some tree removal and vegetation clearing. This

distance exceeds the SISD requirements in Austroads for a 40km/h design speed but the SISD for a

60km/h or 70km/h design speed would be desirable.

There is no kerb or other concrete construction involved with the construction of this option, it

merely widens the proposed sealed road to allocate additional road space for the right turn bay and

uses pavement marking to delineate traffic movements. It has a low level of construction work

required.

3.1 Design Standards Used For Option 1

The following design standards have been used in the development of this option:

• Austroads Guide to Road Design Part 4A: Signalised and Unsignalised Intersections

• Turning movements have been completed for a: 12.6m long Tour Coach.

• Manual of Traffic Signs and Markings (MOTSAM) Part 1: Signs

• Manual of Traffic Signs and Markings (MOTSAM) Part 2: Markings


5 Option 2: T-intersection

Figure 3 shows the concept sketch for Option 2: T-intersection. Refer to Appendix B for a higher

resolution sketch.

Figure 3: Option 2: T-intersection


• The construction of a rural “T” Intersection with left turn lane to continue on Lees Road. The intersection will consist of a flush painted island that is able to be driven over if required by larger vehicles.

• This treatment is an accepted and expected treatment for motorists travelling on a rural

road of this nature, however signage and other treatments prior to the intersection

providing advance warning of the carpark ahead would be critical to it functioning as

required. This type of treatment just prior to the carpark entrance is a safety concern.

• Pavement marking including: o Centrelines and edgelines; o Limit lines to guide traffic to slow down/stop;


o Give way symbols; o Chevron paint inside the splitter island.

• Installation of new signage including: o Give Way signage; o Headway Chevron and Street Name Board. o Threshold Treatment


This option involves pavement construction works in conjunction with pavement marking and

signage to achieve a simple rural T-intersection design that directs traffic to the proposed carpark as

well as providing a left turn facility to continue along Lees Rd. As the through movement will be

directly into the proposed carpark advanced warning signage and threshold type treatment would be

essential to advise motorists that the road ahead enters a carpark and ends. This intersection option

is a safety concern as motorists will need to be aware and be provided with several cues that the road

is ending, so they slow down before entering the carpark. The safety aspects would need to be fully

addressed during detailed design if this intersection form is chosen, however driver cues are likely

to include a threshold type treatment on approach to the intersection which would include signage,

planting, road markings and kerbing.

This option will have little disruption on existing vehicle movements along Lees Road during

construction as a large portion of the works can be constructed offline, allowing 2 way traffic during

construction.

With some tree removal and vegetation clearing, this option will give approaching vehicles 92m of

Approach Sight Distance (ASD) to the limit line of the Give Way. This distance meets the ASD

requirements in Austroads for a 70km/h design speed. 70km/h exceeds the expected design speed

for this section of Lees Rd.

This option will provide vehicles waiting to turn right into Lees Rd approximately 155m of Safe

Intersection Sight Distance (SISD) looking south and approximately 30m looking North into the

carpark. The distance looking south exceeds the SISD requirements in Austroads for a 70km/h

design speed. The SISD from the carpark approach is acceptable as we expect vehicles exiting the

carpark to be travelling at low speed <30 km/h.

This option will require some heavy vehicles to drive over the flush splitter island in order to perform

a turning movement through the intersection, however all usual movements of the design vehicle

can be accommodated within the intersection footprint.

This option will not require any land acquisition on either side of the current road reserve.

There is no kerb or other concrete construction involved with the construction of this option, it

merely widens the proposed sealed road for the intersection form and uses pavement marking to

delineate traffic movements. It has a low level of construction work required.




• Turning movements have been completed for a: RTS18 – Semi Trailer




6 Option 3: 4m Radius Central Island Roundabout

Figure 4 shows the concept sketch for Option 2: 4m Radius Central Island Roundabout with a 7m

wide circulating lane. Refer to Appendix C for a higher resolution sketch.

Figure 4: Option 2: 4m Radius Central Island Roundabout


• The construction of a 4m radius central island concrete roundabout. The roundabout central island will be a fully mountable concrete island that is able to be driven over if required by large vehicles.

• A roundabout would be an unexpected treatment for motorists in this type of rural location.

• Construction of splitter islands comprised of a semi-mountable kerb with concrete infill.

• Construction of new kerb and channel.

• Construction of a heavy duty asphalt pavement to allow for high turning stresses through the roundabout.

• Pavement marking including:


o Centrelines and edgelines to delineate traffic lanes; o Limit lines to guide traffic to slow down/stop; o Give way symbols; o Chevron paint leading to splitter islands.

• Installation of new signage including: o Give Way signage; o Diverge Arrows signage; o Keep Left Arrow signage; o Roundabout Ahead signage.


This option involves concrete and pavement construction works in conjunction with pavement

marking and signage to achieve a simple roundabout design.

The northern leg on Lees Road must be slightly realigned to improve sight distance to the proposed

roundabout. This option will give approaching vehicles approximately 80m of Approach Sight

Distance (ASD) to the limit line with some tree removal and vegetation clearing. This distance

exceeds the ASD requirements in Austroads for a 60km/h design speed.

This option will require some heavy vehicles to mount the outside of the central island in order to

perform a turning movement through the roundabout, smaller vehicles are should use the

roundabout circulating lane as intended. This option does not specifically comply with the

recommended roundabout size and deflection criteria in Austroads Guide to Road Design Part 4B:

Roundabouts and is usually reserved for situations where there is insufficient space to construct a

full roundabout, and/or the roundabout is retrofitted to an existing intersection.




• Austroads Guide to Road Design Part 4B: Roundabouts

• Turning movements have been completed for a: 12.6m long Tour Coach




7 Option 4: 10m Radius Central Island Roundabout

Figure 5 shows the concept sketch for Option 4: 10m Radius Central Island Roundabout. Refer to

Appendix D for a higher resolution sketch.

Figure 5: Option 4: 10m Radius Central Island Roundabout


• The construction of a 10m radius concrete central island roundabout. The proposed roundabout includes splitter islands and a central island consisting of semi-mountable kerb with concrete apron and garden.

• A roundabout would be an unexpected treatment for motorists in this type of rural location.

• Land acquisition will be required.

• Construction of 170m of new semi-mountable kerb and channel.

• Construction of three concrete infilled splitter islands.

• Construction of a heavy duty asphalt pavement to allow for high turning stresses through the roundabout.


• Pavement marking including: o Centrelines and edgelines to delineate traffic lanes; o Limit lines to guide traffic to slow down/stop; o Give way symbols; o Chevron paint leading to splitter islands.

• Installation of new signage including: o Give Way signage; o Diverge Arrows signage; o Keep Left Arrow signage; o Roundabout Ahead signage;


This option will require land acquisition on both sides of the current road reserve and from two

separate land owners which will add to the overall project cost.

The northern leg on Lees Road gets slightly realigned to improve sight distance to the proposed

roundabout. This option will give approaching vehicles approximately 80m of Approach Sight

Distance (ASD) to the limit line with some tree removal and vegetation clearing. This distance

exceeds the ASD requirements in Austroads for a 60km/h design speed.

This option will likely comply with roundabout size and deflection criteria in Austroads Guide to

Road Design Part 4B: Roundabouts.

This option involves the most significant concrete and pavement construction works in conjunction

with pavement marking and signage to achieve a fully built up roundabout design. It is usually

reserved for situations where there are higher traffic numbers to justify the cost of construction.

8 Discussion and Safety

The predicted 2021 peak summer volume of traffic on Lees Road, following commissioning of the

Great Walks, P&R and Lees Rd Carpark, (based on the MWH report “Hot Water Beach to Ferry

Landing Peak Summer Traffic and Parking Assessment” dated 23 March 2016) is 2700 vehicles per

day or 338 vehicles per hour with 2080 of those vehicles accessing the proposed carpark (during

peak summer period). Part of the reason for TCDC's commissioning of this report is to consider

entrance design into the Lees Road carpark entrance that will minimise visitor’s missing the car park

and travelling to the end of the Lees Road. In addition to the carpark entrance design, TCDC is

considering other mitigation measures including signage and parking restrictions with associated

by-laws. These measures will likely reduce projected peak summer volumes at the top end of Lees

Road, and monitoring of traffic volumes will be required to confirm assumptions made in the MWH

report.

Option 1: Right Turn Bay is an intersection type that is accepted and expected by motorists on a

rural road such as Lees Road. Vehicles turning right into the proposed carpark have a central right

turn bay refuge to stop and give way prior to turning into the carpark. This option provides an

appropriate level of service as recommended by Austroads based on the projected peak summer

turning volumes and should provide a high level of safety. This option provides the least effect for

through traffic on Lees Road whilst providing a right turning facility that meets the minimum safety

requirements. This option is the least favoured option in relation to reducing the risk of vehicles

missing the carpark. However, it is considered to be the most favourable option in relation to both

safety and cost.

The following measures could be implemented to address concerns and minimise vehicles missing

the carpark entrance:

1. Installation of appropriate signage: a. Sign at the left side of the car park entrance (Car Park )

Lees Road turn right at the entrance of the carpark, which means that the line of

sight for drivers are towards the car park. This should reduce the risk of drivers

missing the carpark.

b. Sign on the approach to the right turn bay (Car Park 200m) c. Sign at the Lees Road/Hahei Road Intersection (Car park 1500m)

2. Providing a turning opportunity further along Lees Road (for the low risk of vehicles missing the car park) would also mitigate the impact of any vehicles that actually miss the car park. There is a location approximately 200m past the car park that can potentially be used as a turning opportunity, which could be constructed at a lower cost than providing a higher cost option at the entrance to the car park such as a roundabout.

Option 2: T Intersection is an intersection type that is accepted and expected by motorists on a

rural road such as Lees Road. The location of this option at the entrance to the proposed carpark is

a safety concern as a motorist travelling along Lees Road in the northern direction may not realise

that the road ends at the intersection and enters the carpark at speed. If this option was preferred

additional measures would need to be added prior to the intersection including a threshold type

treatment to provide the necessary cues for the motorist to adjust their speed and decide if they are

travelling north on Lees Road or entering the carpark. This threshold treatment would need to

include advanced signage, planting, kerbing and roadmarking. This option is considered the least

safe for motorists out of the four options considered. However, this option is considered the best


treatment for reducing the risk of vehicles missing the car park as the road continues straight into

the car park. However, this treatment will potentially increase speed into the car park which will

increase the risk for conflict between vehicles in the carpark and pedestrians. Although this option

provides the best treatment to ensure vehicles do not miss the carpark entrance, it will still require

the installation of signage along Lees Road to ensure that vehicles are aware that the road will lead

straight into the carpark and adjust their speed accordingly. Directional signage to the carpark at the

Lees Road/Hahei Road intersection would also be required to ensure vehicles turn onto Lees Road.

Option 3 & 4: Roundabout is an intersection type that would be somewhat unexpected by a

motorist on a rural road such as Lees Road. Advanced warning signage, splitter islands and kerbing

would be included with the design to provide the necessary cues to the motorist of the roundabout

intersection ahead. The visual appearance of the roundabout itself on approach would also provide

cues that something is different ahead, so slow down. The roundabout option is a good option for

motorists to make a conscious decision about where they want to go and provides minimal

change/disruption to traffic continuing along Lees Road as well as providing good direction for

traffic into the proposed carpark. Roundabouts provide a good level of intersection safety and for

such low volumes of traffic such as this should work well. Both of the roundabout options are

considered to provide a good level of safety for motorists. The roundabout options are considered to

be the second best treatment for reducing the risk of vehicles missing the carpark as vehicles

naturally need to slow down, make a decision and drive through the roundabout.

The roundabout options will also require the installation of signage along Lees Road to ensure that

vehicles are aware that the carpark entrance is at the roundabout. Directional signage to the

carpark at the Lees Road/Hahei Road intersection would also be required to ensure vehicles turn

onto Lees Road.

Note that:

• The inclusion of Tourist Signage costs have been excluded from the cost estimates. A full

signage strategy will need to be developed by Council in consultation with stakeholders.

• No land acquisition costs have been included.

• The ROC for each option excludes the costs of the proposed seal extension works over the

same extents for each option. Therefore the ROC for each intersection option is the net

physical works cost over and above the cost to complete the proposed seal extension works.

11 Conclusion and Recommendation

The safety aspects of an option should be considered first and foremost when considering the most

suitable type of carpark entrance treatment. As discussed above, the risk of vehicles missing the car

park can be reduced by installing appropriate signage on the approach to the carpark and at the Lees

Road/Hahei Road Intersection and additonally by providing a turning opportunity further along

Lees Road.

Based on the findings detailed in this report it is recommended that Option 1 Right Turn Bay is

adopted as it is the preferred treatment on a rural road as per the Austroads Guide to Road Design

Part 4A: Signalised and Unsignalised Intersections. It is an accepted and expected treatment for

motorists travelling on a rural road of this nature. Additionally, this option is low cost, will meet all

functional requirements of the entrance treatment and provides a high level of safety.

The roundabout options would also provide a good intersection treatment at this location and

possibly better direction for traffic entering the carpark, i.e. less vehicles missing the car park

entrance and travelling north along Lees Road. Both of the roundabout options would provide a good

level of safety at a higher cost than the basic right turn bay treatment and would be the preferred


option if the main consideration for the intersection treatment was to ensure the least amount of

vehicles missed the proposed carpark entrance.

The location of this the T-intersection option at the entrance to the proposed carpark is a safety

concern as a motorist travelling along Lees Road in the northern direction may not realise that the

road ends at the intersection and enters the carpark at speed. Therefore this option is considered

the least safe for motorists out of the four options considered. However, if this option was preferred,

the risks may be reduced by installing additional measures prior to the intersection including a

threshold type treatment to provide the necessary cues for the motorist to adjust their speed and

decide if they are travelling north on Lees Road or entering the carpark. This threshold treatment

would need to include advanced signage, planting, kerbing and roadmarking.

It is understood that Council will undertake consultation with the relevant stakeholders to further

develop the preferred car park entrance treatment based on the concept designs provided in this

report. Once a preferred entrance treatment has been agreed upon, Opus would be happy to provide

an offer of service for the detailed design and procurement of the works.
