Macquarie Links Estate – TMP 07th April 2016 iii
Executive summary
Macquarie Link Estate (the Estate) is a gated community located 42 kilometres south-west of the Sydney
CBD and is part of City of Campbelltown Local Government Area. The Estate has been developed over
last 15 years and comprises 18 Stages with approximately 400 homes and a golf course.
Caldwell & Kent Consulting (CKC) were engaged by Macquarie Links Estate (the Estate) to develop a
Masterplan for introduction of traffic calming measures and to investigate options to increase available
parking provision. The primary objective of this study is to develop an overarching strategy that will
guide the Committee members in selecting treatments of each individual section.
Methodology
CKC has provided Macquarie Links Estate a detailed review of the existing traffic and parking conditions
prevalent with the Estate, which includes the following:
Preliminary Analysis
o Inception Meeting;
o Working Group Meeting;
o Detailed Site Visit;
o Review of Existing Data; and
o Existing Parking Demand Analysis.
CKC have conducted regular on-site observations to better understand to magnitude of the issues.
Existing peak parking demand has been estimated and compared to existing parking supply to
determine estimated short falls.
Identification of Issues
o Identification of Problem Areas;
o Categorisation of Identified Issues;
o Development of Possible Solutions;
o Pros& Cons of each Option Proposed;
o Presentation of the Draft Options to the Committee; and
o Consultation with all the Stake Holders.
As part of this stage, CKC have also included an analysis to outline the recent issues and assess the
effectiveness of the measures undertaken since 2010.
In addition the driving behaviours have been assessed – particularly in regards to speeding at various
points around the Estate. CKC have recommended mitigation and traffic calming measures to address
areas of concern that have been outlined in the report.
Macquarie Links Estate – TMP 07th April 2016 iv
The main issues noticed within the estate include:
The 2015 speed surveys indicated that the 85th percentile average speed at the surveyed
locations varied between 46-56kmph (traditionally 85th percentile speed was used to set speed
limit) within a 40kmph speed environment;
The 2015 surveys suggested that at the majority of the surveyed locations, less than 30% of
vehicles were adhering to the posted speed limit of 40kmp - indicating a traffic calming device is
required at these locations to slow down the vehicles;
The Estate by-laws generally prohibits on-street parking (except in designated areas) however,
residents were observed to be parking along a majority of the streets servicing the Estate; and
The review of the historical data suggested that the installed traffic calming devices along the
section of Macquarie Links Drive have reduced the overall travel speed. However, the 2015
survey results suggested that there are still a proportion of drivers who speed and therefore, the
installed devices are required to be modified to be further effective in slowing down the
vehicles.
CKC have provided a list of recommendations that address these issues including the following:
Introduce traffic calming device along the section of Macquarie Links Drive located North of the
Pedestrian Crossing;
Introduce traffic calming device along the section of Governors Way located west of the existing
pedestrian crossing servicing the bus stop at Stage 2 of the Estate;
Introduce traffic calming device along the section of Governors Way on approach to Apartment
Villas;
Introduce road rumbles along Macquarie Links Drive near the entrance;
Modify the existing slow points to reduce the vehicular speed along the section of Macquarie
Links Drive located near the Golf Course Entrance;
Introduce on-street parking on all the street servicing the Estate;
Modify the existing traffic circulation along the streets servicing the Stage 1, 3, 4, 7, 8,9, 10 & 11
Additionally as part of this review CKC have developed a long term plan including a standard process and
a point scoring system that will assist in assessing whether there is a speeding issue or not. This
assessment will assist in identifying the severity of the issue and help in selecting an appropriate traffic
calming devices. Lastly, we have also prepared a list of strategies to not only increase the on-street
parking provision but also to manage the on-street parking demand.
Draft Report
CKC submitted a draft report to the Committee which was presented to the all the stage representative
at their monthly meeting held on 1st of March 2016. The purpose of the presentation was to explain the
methodology and the reasoning behind the proposed recommendations. As part of the proposed
Macquarie Links Estate – TMP 07th April 2016 v
recommendation multiple options were presented to the Committee summarising the pros and cons of
each measures and the committee was requested to nominate the preferred options/measures to be
included as part of the final report.
Following presentation, the representatives were given two weeks time to review the report including
the findings and provide necessary comments to be included as part of the final report. The list below
provides the summary of the comments raised by the Committee members:
Agreement on modification of the existing Traffic Calming Measure along Macquarie Links at
speed survey Location 2;
Need for Introduction of a Traffic Calming Measure along the Governors Way (Near Stage 2 of
the Estate);
Impact of the existing community bus services on the proposed on-street parking provision;
Preference for introduction of vertical deflection devices over horizontal deflection devices. The
preferred Traffic Calming devices was identified as a Speed Cushions;
Details about the Proposed On-street Parking arrangement along Macquarie Links Drive and
Governors Way;
Limited availability of on-street parking within Villa East and its impact on the residents of Stage
7; and
Request for example of kerb mountable parking implemented elsewhere in NSW.
Key Recommendations
Following the presentation of the Draft Report CKC recommends that the Estate progress with the
actions listed below:
Priority Items
Modify the existing slow points to include speed cushion that will assist in reducing vehicular speed at Location 2;
Introduce traffic calming device (speed cushions)at Location 6 of the speed surveys;
Introduce on-street parking within Stage 3 & Stage 4;
Modify the existing traffic circulation along the streets servicing the Stages 3, & 4;
Introduce traffic calming device (speed cushions) at Governors Way on approach to the pedestrian crossing connecting the recreational area (refer to Section 4.2 of this report);
Introduce traffic calming device (speed cushions) at Location 3 of the speed surveys; and
Introduce on-street parking along Governors Way and Macquarie Links Drive;
Introduce no-stopping zones within the turning area associated with the Cul-de-Sac
The Estate should consider utilising VMS sign on a temporary basis to educate the residents; and
In absence of the enforcement by the authorities the committee is left with only one choice i.e. to enforce the traffic control measures on their own with the assistance from the existing security company.
Macquarie Links Estate – TMP 07th April 2016 vi

1 Introduction Caldwell & Kent Consulting (CKC) were engaged by Macquarie Links Estate (the Estate) to develop a
Masterplan for introduction of traffic calming measures and to investigate options to increase available
parking provision.
Macquarie Links Estate (the Estate) is a gated community located 42 kilometres south-west of the
Sydney CBD and is part of City of Campbelltown Local Government Area. The Estate has been developed
over last 15 years and comprises 18 Stages with approximately 400 homes and a golf course. The Golf
Course is privately owned and includes a proposal for the construction of a new function centre. The
Golf Course operates independently to the residential development and has an adequate on-site parking
provision to cater for the typical operation of the Golf Course and its associated activities.

2 Site Description 2.1 Macquarie Links Estate
Macquarie Links Estate (the Estate) is a gated community located 42 kilometres south-west of the
Sydney CBD and is part of City of Campbelltown Local Government Area. The Estate has been developed
over last 15 years and comprises 18 Stages with approximately 400 homes and a golf course.
The residential development was completed in a staged process and comprises 14 Stages of housing, 3
stages of villas and 1 apartment strata. The residents also have access to community facilities which
include a swimming pool, tennis court, BBQ and Golf Course all of these facilities have a potential to
generate travel and parking demand.
The Estate operates as a community association (i.e. each completed Stage has an independent Strata
Manager and a committee). In addition to the above there is an executive committee which includes an
Estate Manager whose responsibilities include the maintenance and improvement of the overall estate.
Figure 2- The Estate - Staging Plan
Macquarie Links Estate-TMP 07th April 2016 4
Vehicular access to the Estate is available via Williamson Road and connects to Macquarie Links Drive
which is a private road. The entrance to the Estate is controlled utilising a boomgate control and an
additional security officer is available at the entrance to monitor the vehicles accessing the site.
The following are the two major private roads servicing the Estate which have a posted speed limit of
40kmph:
Governors Way; and
Macquarie Links Drive
Governors Way is a local private road which primarily provides vehicular access to Stages 2, 3, 4, 10, 11,
13, 14 and Peak Villas & Peak Apartment. The carriageway is undivided and comprises one traffic lane in
each direction with no on-street parking provision.
Macquarie Links Drive is a local private road which provides vehicular access to Stages 1, 6, 7, 8, 9, 12,
15 & Villas East. The carriageway is undivided and comprises one traffic lane in each direction with on-
street parking provision available along sections of Macquarie Links Drive.
We note that all roads servicing the Estate have a posted speed limit of 25kmph except Macquarie Links
Drive and Governors Way (which have a posted speed limit of 40kmph).
Community Buses
The Estate operates regular community bus services on weekday (except for public holidays). The
community bus service connects the Estate with Ingleburn Railway Station and is accessible via the 17
bus stops located across the various section of the Estate. These services operates during the peak
periods (both morning and afternoon peak period) with a frequency of approximately one service every
20 minutes or so.
The figure below presents location of the bus stops across the Estate.

Figure 3 – Bus Stop Locations (Source - Macquarie Links Estate Website)
In addition to the above there are approximately six school bus services which are accessible via the bus
stop located outside the Estate. Please note while determining the on-street parking capacity within the
Estate we have assumed the bus stops to be a maximum of 12 metres long resulting in a loss of two (2)
car spaces per stop.

3 Data Review 3.1 Review of the Speed Surveys
The Estate Committee had received numerous complaints from the residents stating that the vehicles
accessing the Estate were travelling at a higher speed than the posted speed limit. Subsequently, the
Estate had undertaken speed surveys in July 2010. The speed surveys were undertaken utilising
automated tube counts for a 24 hour period across a full week. The surveys were undertaken at five
locations along both Macquarie Links Drive and Governors Way. The survey results confirmed the
residents concern. The survey results showed 60% of the vehicles accessing the Estate exceeded the
posted speed limit (of 40kmph) by up to 20kmph and some uncontrolled individuals were observed to
be travelling at speeds up to 100kmph.
Following review of the speed surveys, the committee identified a few high priority locations to install
traffic calming measures along Macquarie Links Road and Governors Way Road. The committee agreed
to monitor the speed of vehicles by undertaking speed surveys on an annual basis. The recent speed
surveys were undertaken in December 2015 and included an additional location along Governors Way.
A comparison of the 2015 speed survey result (of all vehicles accessing the Estate) with the 2010 results
are summarised in the table below:
Table 1 – Summarised Comparison of 2015 and 2010 Speed Survey

2010 0.0% 0.3% 1.7% 11.1% 38.0% 36.9% 10.6% 1.2% 0.1% 0.0% 0.0%
2015 0.0% 0.5% 2.9% 23.2% 49.1% 20.5% 3.2% 0.5% 0.0% 0.0% 0.0%
Difference 0.0% 0.2% 1.2% 12.1% 11.2% -16.4% -7.5% -0.7% -0.1% 0.0% 0.0%
A comparison of the survey results indicate that in 2015 approximately 76% were travelling at a speed
less than or equal 50kmph compared to 51% in 2010 - suggesting that the installed traffic calming
devices are contributing to the desired objective i.e. slowing down the vehicles.
The locations at which the 2015 speed surveys were undertaken is shown on the figure overleaf:
Macquarie Links Estate-TMP 07th April 2016 7
Figure 4 – Speed Survey Locations The 2015 surveyed further indicated that the 85th percentile speed at the surveyed locations varied
between 46-56kmph (traditionally 85th percentile speed was used to set speed limit) within a 40kmph
speed environment. The summary of the speed surveys is summarised in the table below:

Macquarie Links Estate-TMP 07th April 2016 8
The survey results indicate vehicle accessing Location 4 (along Macquarie Links Drive near Jane Jarvis
Way) had a higher proportion of drivers that were adhering to the posted speed limit of 40kmph. We
understand that recently a speed hump was installed at this location which has forced vehicles to slow
down.
Based on our discussion with the representatives we understand that the selected location 2,3,5 & 6 for
the 2015 surveys are new locations (which were not included in the previous surveys). These locations
were selected as the residents had raised the concerns about speeding within the Estate. The review of
the historical data suggested that the installed traffic calming devices along the section of Macquarie
Links Drive have reduced the overall travel speed. However, the 2015 survey results suggested that
there are still a proportion of drivers who speed and therefore, the installed devices are required to be
modified to be further effective in slowing down the vehicles.
Furthermore at Location 3, 5, & 6 less than 30% of vehicles were adhering to the posted speed limit of
40kmp - indicating a traffic calming device is required to slow down the vehicles.
3.2 Review of the On-street parking demand
The Estate is anticipated to reach its full planned growth (approximately 400 homes completed and
occupied) with the completion of the last stage to be finished by the end of this year. As part of the
planning proposal all parking is required to be restricted to on-site i.e. no on-street parking permitted.
However, as a result of the recent growth the Estate has been experiencing a significant increase in the
overall parking demand. This activity has forced residents and their visitors to park on-street thereby
breaching the planning policies of the Estate. Therefore, the Committee is investigating options to
increase the parking provision by introducing on-street parking and opportunities to create additional
parking provision on community lots.
Majority of the street servicing the Estate do not have line markings indicating the on-street parking
provision except a section of Macquarie Links Drive and Governors Way. However, during our site visit
we had observed vehicles were parked on along the remaining majority of the internal streets.
Therefore, in absence of line marking indicating on-street parking zone CKC had established on-street
parking capacity based on the aerial image.
A review of the aerial image indicating the road network servicing the Estate was undertaken to
understand the potential on-street parking capacity within the Estate. In order to determine the on-
street parking capacity along a street we have assumed that the standard parking space will include the
following dimensions:
Space Length – 6.0 metres; and
Space Width – 2.1 metres
Macquarie Links Estate-TMP 07th April 2016 9
Following our review and based on the existing parking utilisation CKC has established that the existing
streets servicing the Estate have a potential to accommodate approximately 719 car spaces.
Furthermore, we had noticed generally on streets where residential homes were located on either side
of the carriageway cars were observed to be parked on both side of the Kerb.
Macquarie Links Drive and Governors Way are the two major roads servicing the Estate. Currently, on-
street parking is available on certain section of both Macquarie Links Drive and Governors Way. The
existing on-street parking along Macquarie Links Drive follows a kerb mountable parking arrangement
(i.e. drivers are required to have their vehicles wheel along the raised section of the kerb) and these
Kerb mountable spaces were observed to have a width of 1.5 metres.
The following photograph indicates the kerb mountable on-street public parking Implemented
elsewhere in NSW.
Figure 5- Example of Kerb Mountable Parking Implemented in Balmain and Rozelle
Generally, both Macquarie Links Drive and Governors Way have a carriageway width of approximately
8.8 metres (Kerb to kerb). Following a review of the on-street parking demand CKC recommends kerb
Macquarie Links Estate-TMP 07th April 2016 10
mountable on-street parking should be introduced on both sides of the carriageway. The Australian
Standard recommends a carriageway width of minimum of 5.5 metres is required to accommodate two-
way traffic flow. Therefore, following introduction of the kerb mountable on-street parking along both
Macquarie Links Drive and Governors Way, on both sides of the carriageway, will result in an effective
carriageway width of 5.8 metres which is considered adequate for accommodating two way traffic flow.
A section of Macquarie Links Drive located to the north of the Golf Course Entrance has a unique
carriageway characteristic comprising low mountable kerb on the western side whereas, the eastern
side of the carriageway accommodates a barrier kerb. Furthermore, residential developments are
located on either side of Macquarie Links Drive - resulting in on-street parking demand on both sides of
the carriageway. In order to introduce on-street parking along this section of Macquarie Links Drive we
recommend the following:
Along Low Mountable kerb – the standard on-street kerb mountable parking should be
introduced; and
Along Barrier kerb – 1.8 metres wide parking bay should be marked.
Following introduction of the on-street parking along the above section of Macquarie Links Drive, on
both sides of the carriageway, will result in an effective carriageway width of 5.5 metres which is
considered adequate for accommodating two way traffic flow.
The carriageways of internal roads servicing the Estate have a width ranging from 5.0-7.0 metres. The
introduction of on-street parking, on both sides of the kerb, will result in an effective carriageway width
of approximately 3.0-4.0 metres which is considered inadequate to accommodate two way flows.
Therefore, in order to introduce on-street parking along internal roads servicing the Estate, some of the
existing streets are required to be converted to accommodate one-way circulation. Detailed breakdown
of the parking capacity along each individual streets are presented as Table 4.
In order to develop the traffic circulation, along the various section of the Estate, we have adopted the
Standard Clockwise vehicular circulation approach practiced in Australia. For determining the direction
of travel along the intermediate streets we have utilised the existing on-street parking behaviour. For
example, vehicles were parked on both sides of kerb along James Meehan Way and a majority of the
cars were noticed to park with their nose facing in an eastern direction, therefore the direction of travel
along this street was proposed to allow vehicles to travel from west to east (i.e Lord Castlereagh CCT to
Barrack CCT). Attachment C presents the proposed modifications to the traffic circulations to
compliment the introduction of on-street parking.
3.3 On-Street Parking Demand
The Estate is a residential development and the majority of the residents are likely to be home at night
time. Therefore the Estate is highly likely to experience peak parking demand during the night time and
weekends. To understand the current parking demand experienced within the Estate on-street parking
surveys were undertaken on a weeknight and a Saturday night.
Macquarie Links Estate-TMP 07th April 2016 11
The survey results indicated 158 cars and 211 cars were parked on-street on a weeknight and Saturday
night respectively. The Estate experienced greater parking demand on a Saturday night than the
Weeknight- this behaviour is anticipated as the residents are likely to attract visitors on a weekend.
Attachment D presents a detailed breakdown of the existing on-street parking demand experienced on
individual streets across the Estate.

Total Capacity 719 158 211
It is evident from the above surveys that the Estate experiences relatively lower parking demand (i.e.
one third of the total on-street parking capacity) and the existing parking supply of approximately 719
car spaces is more than adequate to cater for any potential increase in parking demand. Furthermore, a
review of the on-street parking demand on individual streets indicates that the parking demand is less
than the parking capacity of the street.
In future if the Estate experiences a greater parking demand than the existing parking capacity of the
Estate there are potential areas which can be modified to further increase the on-street parking
provision by introducing parking along the Golf Course frontage.
Furthermore, during our site visit we had observed vehicles were parked within the turning area
associated with the Cul-de-Sac for example, Jarvisfield Place, Strathwallen Close, and Dromedary Place.
This behaviour of the residents prohibits vehicles from turning around and forces drivers to utilise the
driveways to turn around thereby intruding the privacy of the residents. To mitigate this we recommend
“No-Stopping” areas should be introduced within the turning areas and the residents be advised to
utilise available on-street parking. Attachment B presents the proposed on-street parking plan.
Macquarie Links Estate-TMP 07th April 2016 13
4 Assessment of the Existing Conditions 4.1 Review of the Existing Traffic Calming Measures
There are number of traffic calming devices installed within the Estate and consists of the following
devices:
Speed Humps;
Roundabouts;
Slow Points;
Raised Pedestrian Crossing; and
Marked Pedestrian Crossing.
These devices are located along Macquarie Links Drive and Governors Way. The review of the 2015
speed surveys suggests that these devices are generally slowing down the vehicles except the slow
points (Slow Points represents a series of kerb extensions on alternating or opposite sides of the
roadway, which narrows and/or angle the roadway) located along Macquarie Links Drive. The review of
the historical data suggested that the installed traffic calming devices along the section of Macquarie
Links Drive have reduced the overall travel speed. However, the 2015 survey results suggested that
there are still a proportion of drivers who speed and therefore, the installed devices are required to be
modified to be further effective in slowing down the vehicles.
To mitigate this CKC recommend the exiting slow points should be modified to include a vertical
deflection device (i.e. speed cushions) resulting in a Hybrid solution. The only disadvantage of
introducing the vertical clearance device is that it may increase traffic noise level due to the increased
number of braking and accelerating actions and the vertical displacement of vehicles and goods.
Alternatively, the geometry of these slow points can be modified to create a Horizontal Deflection which
is required to slow down the vehicles. Note that the horizontal deflection should be moderately
increased to ensure large vehicles can still manoeuvre through.
The review of the existing slow points along Macquarie Links Drive suggested that these slow points are
located near the resident houses and therefore, the introduction of vertical deflection devices may
result in an increase in traffic noise levels. The slow point located near 21 Macquarie Links Drive has only
one residential house located on approach to this device and thus, as part of the priority
recommendations we suggest modifying the existing slow point along Macquarie Links Drive (located at
21 Macquarie Links Drive) to include vertical deflection devices. The proposed recommendation is
shown in Figure 6 presented overleaf. CKC recommends the committee should continue monitoring the
speeds on an annual basis – this will assist in assessing the effectiveness of the installed devices.

4.2 Review of the existing Pedestrian Facilities
CKC had undertaken a site visit to identify the potential pedestrian activity generators located within the
Estate. The site visit indicated that the major pedestrian activity generators are as follows:
Entrance to the Golf Club;
Entrance to the Community Recreational Centre; and
Bus Stop servicing the buses operated by the Estate.
The review further indicated the above locations were serviced by a dedicated raised pedestrian
crossing with the exception of the marked pedestrian crossing connecting the Community Recreational
Centre. The marked pedestrian crossing is located on a curved section of Governors Way, north of the
intersection of Governors Way and Macquarie Links Drive which results in limited visibility of the on-
coming vehicles. The limited visibility along the marked pedestrian crossing is likely to result in an unsafe
condition for both the pedestrians and the vehicles accessing this area. There are potentially two
options to mitigate this-either to convert this marked pedestrian crossing into a raised pedestrian
crossing which will slow down the vehicles or to introduce a speed hump on approach to the marked
pedestrian crossing.

4.2 Other Considerations
The discussions with the representatives indicated the residents of Villa East, were observed to utilising
the community owned land located within Stage 7 of the Estate to park their vehicle. However, our
observations (from the on-street parking) suggested the existing on-street parking within Villa East was
underutilised. Thus the availability of the on-street parking spaces indicate the existing on-street parking
provision is adequate to cater for the on-street parking demand generated by the residents of the Villa
East.
In an event the on-street parking demand generated by the residents of Villa East is greater than the
available parking supply – the committee can consider either of the following two options:
Modify the existing two way traffic flow along Jane Jarvis Way to accommodate one way (i.e. in
southbound direction) and introduce on-street parking along eastern side of the kerb. The
recommended traffic flow and the on-street parking conditions presented in the Figure 8;
and/or
Introduce parking along the community owned land – we understand this exercise is likely to be
expensive than the first option.

5 Stakeholder Consultations 5.1 Stakeholder Meetings
Caldwell & Kent Consulting (CKC) attended the Executive Committee meeting with the representatives
of individual Stages of the Estate. The purpose of the meeting was to understand the traffic and parking
issues encountered within various stages of the Estate- which provides valuable help in staging the
proposed recommendation works.
The committee meeting was organised in December 2015 and was attended by most of the
representatives of the individual stages. During the meeting a majority of the stage representatives
indicated generally the residents adhere to the posted speed however the Estate is experiencing a
change in the demographic characteristic of the resident. Traditionally the residents of the Estate
comprised of experienced drivers however with the demographical changes in the age groups it now
includes a proportion of teenagers who are considered as inexperienced drivers and are generally
vulnerable to breaking the implemented road rules/conditions.
In relation to the parking behaviour of the residents, the representatives suggested that the Estate has
experienced a significant increase in car ownership as the children of the residents have now started
driving. Furthermore, the representatives suggested that the children of residents of the Estate are
continuing to live at home for longer due to the economic/real estate growth experienced across NSW.
The representative further suggested that the number of residents are now utilising their garages for
storage resulting in vehicles parked on-street- which is a breach of the by-laws.
There was a general consensus among the representatives to reconsider the by-laws to introduce on-
street parking. Lastly, one of the stage representative suggested in order to increase on-street parking
provision, the residents of Estate would prefer modification of the existing traffic circulation to
accommodate one way circulation.
5.2 Stakeholders Consultation
We recommend that the Committee should continue engaging with residents to identify the areas that
require upgrade/needs to be investigated. Furthermore the standard process for introduction of a by-
law should include a consultation session with the residents to inform them about the proposed
amendments and the likely benefits these amendments will provide. Following a feedback from the
residents if deemed appropriate the Committee should reconsider the modifications to address/include
any comments provided.
Macquarie Links Estate-TMP 07th April 2016 18
6 Proposed Recommendation The primary objective of a successful and efficient traffic management system is to create safer road
network for all road users including pedestrians. The traffic management system should include as a
minimum the fundamental 3 E’s of traffic engineering principles which are as follows:
Education;
Engineering; and
Enforcement.
6.1 Education
Based on our discussion with the Committee and Stakeholders we understand that a proportion of the
resident drivers comprise of teenagers who have recently started driving. There is a probability that
these drivers are unaware of the prevailing conditions implemented within the Estate.
Therefore to educate the residents of the prevailing conditions implemented within the Estate adequate
signage should be installed within the Estate. This may be undertaken by the form of road marking
indicating the applicable speed limits within the Estate or Leaflet drop out indicating of the changes
implemented on the site or messages on the Estate website/community notice board.
Recent research studies have indicated that the use of Variable Message Sign (VMS) informing the
individual vehicle travel speed accompanied by proper enforcement were effective in implementing the
posted speed limit. Therefore, CKC recommends that the Estate should utilise this VMS sign on a
temporary basis to educate the residents.
6.2 Engineering
In relation to the engineering measures the following Traffic Calming devices were reviewed and pros
and cons of each measure are discussed in this section.
Based on the review of the Austroads Guide to Traffic Management following are the effective measures
for reducing the travel speed:
Vertical Deflection ; and
Horizontal Deflection.
Vertical Deflection
As the name suggests these are the devices which results in vertical deflection of vehicles and thus
forcing drivers to slow down while negotiating these devices. The following are the standard equipment
that can be used to introduce vertical deflection to slow down the vehicles:
Road Hump;
Road Cushions;
Macquarie Links Estate-TMP 07th April 2016 19
Flat Top Road Hump;
Wombat Crossing; and
Raised Pavement.
The pros and cons of the above vertical deflection equipments are as follows:
Pros
Results in significant reduction in vehicle speeds;
Relatively low cost to install and maintain;
Likely to discourage through traffic;
Cons
Traffic noise level may increase due to the increased number of braking and accelerating actions and the vertical displacement of vehicles and goods;
Uncomfortable for vehicle passengers; and
Adversely affect access for buses, commercial vehicles and emergency vehicles. Furthermore, from our on-site discussions we understand there is a considerable opposition (from the
residents) to the installation of vertical deflection traffic calming measures.
Horizontal Deflections
The alternative form of devices to slow the vehicles is to introduce horizontal deflection and following
are the equipment which can be used to introduce Horizontal deflection required to slow down the
drivers:
Kerb Extensions;
Slow Points;
Centre Blisters; and
Roundabout.
The pros and cons of the horizontal deflection equipment are as follows:
Pros
they reduce vehicle speeds when properly designed and installed;
they prevent vehicles from overtaking each other;
they can provide a refuge for pedestrians and cyclists crossing the street;
their flexibility in design allows buses and commercial traffic to be accommodated;
they may visually enhance the street through landscaping; and
they have relatively little effect on emergency vehicles.
Macquarie Links Estate-TMP 07th April 2016 20
Cons
they reduce the amount of available kerbside parking;
possible increase in traffic noise;
Will inhibit vehicular access arrangement to the driveways located within the vicinity of the slow point; and
Drivers may mistake an empty kerbside parking lane for a traffic lane resulting in a potential unsafe road environment.
A review of the 2015 speed surveys and our on-site observations indicated the following locations require a traffic calming devices:
Introduce traffic calming device at Location 3 of the speed surveys;
Introduce traffic calming device at Location 6 of the speed surveys;
Introduce traffic calming device at Location 5 of the speed surveys;
Introduce road rumbles along Macquarie Links Drive near the entrance; and
Modify the existing slow points to reduce the vehicular speed at Location 2. A copy of the proposed recommendation is presented as Attachment A. Spacing between various Traffic Calming Devices A number of studies were undertaken by the various road research authorities to identify the maximum spacing between traffic calming devices. These studies concluded that within a 40kmpn road environment- the traffic calming devices which have the potential to reduce speeds to 20kmph should be spaced at a maximum of 120 metres. The review of the historical speed data suggests that following introduction of speed calming devices along Macquarie Links Drive there has been a substantial reduction in vehicle speeds. However, the 2015 surveys suggests that there are still a proportion of drivers who speed and therefore, the installed devices are required to be modified to be further effective in slowing down the vehicles. CCK has recommended modifying the existing slow points to include vertical deflection devices which are likely to improve the performance of these slow points. As an alternative the committee can investigate opportunities to introduce additional slow points along Macquarie Links Drive. As the research studies suggested closely spaced devices are also likely to result in reduction of vehicle speeds and thus, increasing the operational efficiencies of these slow points. Development of Final Report
CKC submitted a draft report to the Committee which was presented to the all the stage representative
at their monthly meeting held on 1st of March 2016. The purpose of the presentation was to explain the
methodology and the reasoning behind the proposed recommendations. As part of the proposed
recommendation multiple options were presented to the Committee summarising the pros and cons of
each measures and the committee was requested to nominate the preferred options/measures to be
included as part of the final report.
Macquarie Links Estate-TMP 07th April 2016 21
Following presentation, the representatives were given two weeks time to review the report including
the findings and provide necessary comments to be included as part of the final report. The list below
provides the summary of the comments raised by the Committee members:
Agreement on modification of the existing Traffic Calming Measure along Macquarie Links at
speed survey Location 2;
Need for Introduction of a Traffic Calming Measure along the Governors Way (Near Stage 2 of
the Estate);
Impact of the existing community bus services on the proposed on-street parking provision;
Preference for introduction of vertical deflection devices over horizontal deflection devices. The
preferred Traffic Calming devices was identified as a Speed Cushions;
Details about the Proposed On-street Parking arrangement along Macquarie Links Drive and
Governors Way;
Limited availability of on-street parking within Villa East and its impact on the residents of Stage
7; and
Request for example of kerb mountable parking implemented elsewhere in NSW.
Detailed lists of the comments from the Stage Representatives on the draft report are presented as
Attachment F.
Key Recommendations
Following the presentation of the Draft Report CKC recommends that the Estate progress with the
actions listed below:
Priority Items
Modify the existing slow points to include speed cushion that will assist in reducing vehicular speed at Location 2;
Introduce traffic calming device (speed cushions)at Location 6 of the speed surveys;
Introduce on-street parking within Stage 3 & Stage 4;
Modify the existing traffic circulation along the streets servicing the Stages 3, & 4;
Introduce traffic calming device (speed cushions) at Governors Way on approach to the pedestrian crossing connecting the recreational area (refer to Section 4.2 of this report);
Introduce traffic calming device (speed cushions) at Location 3 of the speed surveys; and
Introduce on-street parking along Governors Way and Macquarie Links Drive;
Introduce “no-stopping zones” within the turning area associated with the Cul-de-Sac
The Estate should consider utilising VMS sign on a temporary basis to educate the residents; and
In absence of the enforcement by the authorities the committee is left with only one choice i.e. to enforce the traffic control measures on their own with the assistance from the existing security company.
Secondary Items
Macquarie Links Estate-TMP 07th April 2016 22
Introduce on-street parking along all the street servicing the Estate;
Modify the existing traffic circulation along the streets servicing the Stage 1, , 7, 8, 9,10 & 11;
Introduce traffic calming device (speed cushions) along the section of Governors Way at
Location 5;
Introduce road rumbles along Macquarie Links Drive near the entrance;
Introduce on-street parking along Villa East and modify the existing traffic circulation along the
Jane Jarvis Way.
Future Considerations The assessment of the existing traffic and parking conditions within the Estate suggested that the
proposed recommendations should be adequate to resolve the identified issues. However, in an event if
it is observed that the proposed recommendations are inadequate and additional measures are required
to improve the traffic and parking facilities. CKC recommends the Committee should consider (but not
limited) to the following actions;
Investigate options to connect Stage 4 with the Governors Way;
Investigate options to connect Governors Way and Macquarie Links Drive via Dromedary Place;
and
Introduce parking along the community owned land.
The images presented below indicate examples of on-street parking introduced along the community
owned areas.

6.2 Enforcement
Based on our discussions with the Management Committee we understand the committee had
requested both the NSW Police and Campbelltown City Council for assistance in enforcing the posted
speed limits and on-street parking restrictions implemented within the Estate. Both the authorities have
declined the committee’s request suggesting that the road network servicing the Estate is privately
owned and therefore, it is outside their respective jurisdiction.
In absence of the enforcement by the authorities the committee is left with only one choice i.e. to
undertake the enforcement on their own. We understand in the past the Committee had employed the
existing security company to undertake random speed observations to record the details of the vehicles
speeding within the Estate. We also understand that there is a provision under the Estate bylaws which
permits the Committee to restrict a particular vehicle from accessing the Estate.
We encourage the Committee to continue engaging the security personals to randomly record the
details of the speeding vehicles. Following which the speeding drivers should be banned (for a short
duration) from entering the Estate.
6.3 Long Term Planning
The Estate committee should consider developing/implementing a standard process for identifying the
potential areas which are experiencing speeding issues. This process can also be utilised to ascertain the
type of traffic calming devices required to mitigate the identified issues. This process can become a
standard to categorise issues, prioritise each issue and provide mitigations strategy.
The chart below provides an example of the standard process applied to “speeding”.

the surveys are repeated post installation to determine the effectiveness of the installed
measure if the issue is not resolved this process is repated
Macquarie Links Estate-TMP 07th April 2016 25
The Estate will need to develop a system to evaluate the severity of each issue. The point scoring system
was developed with reference to the Austroads Guide to Traffic Management System - used by majority
of Council’s around Australia to identify, develop and implementing a Local Area Traffic Management
System.
The Guide recommends the point scoring system should include the review the existing traffic
conditions including the crash history.

On-Street Parking Demand
In an event the on-street parking demand exceeds the identified parking capacity than the Committee
should consider (but not limited) to the following actions;
investigate opportunities to increase on-street parking by modifying the existing on-street
parking configuration for example, introducing on-street parking along the golf course end of
the kerb;
Investigate opportunities to introduce parking within the community owned land; and
Introduce measures to encourage usage of sustainable modes of transport.
Introduce policy to restrict car ownership i.e. maximum number of vehicles a resident can own
(Highly Contentious but mentioned to ensure all possibilities are stated);
Macquarie Links Estate-TMP 07th April 2016 27
7 Conclusion The Estate has a potential to introduce an on-street parking provision of approximately 719 car
spaces.
On-street parking surveys indicated that the Estate experiences a peak parking demand of
approximately 211 cars on a Saturday night- indicating the on-street parking provision is more
than adequate to cater for the existing parking demand.
A comparison of the survey results indicate that in 2015 approximately 76% were travelling at a
speed less than or equal 50kmph compared to 51% in 2010 - suggesting that the installed traffic
calming devices are achieving their desired objective i.e. slowing down the vehicles.
We understand that a proportion of the resident drivers comprise of teenagers who have
recently started driving and therefore, CKC recommends that the Estate should consider utilising
the VMS signs on a temporary basis to educate the residents.
A review of the 2015 speed surveys and our on-site observations indicated the following locations require a traffic calming devices:
o Introduce traffic calming device at Location 3 of the speed surveys; o Introduce traffic calming device at Location 6 of the speed surveys; o Introduce traffic calming device at Location 5 of the speed surveys; o Introduce road rumbles along Macquarie Links Drive near the entrance; and o Modify the existing slow points to reduce the vehicular speed at Location 2
In absence of the enforcement by the authorities - the committee is left with only one choice i.e.
to enforce the traffic control measures on their own with the assistance from the existing
security company.
