1 Introduction

Cardno has been engaged by Manzeene Avenue Development Project Trust Pty Ltd to undertake a traffic

engineering assessment of the proposed rezoning of a parcel of land on the east side of O’Hallorans Road in

Lara, from Rural Living to the General Residential Zone. A Development Plan Overlay is proposed for the

site, which will provide planning guidelines for its future development.

In the course of preparing this report, the subject site and its environs have been inspected, and plans of the

proposal and relevant background information has been examined.



2 Background

2.1 Location and Land Use

The subject site is an irregular parcel of land, located on the east side of O’Hallorans Road between

Windermere Road and Patullos Road in Lara.

The site has a road frontage to Manzeene Avenue, O’Hallorans Road and Kees Road, with a total site area

of approximately 60 hectares. It is noted that the subject site is located within the Lara Structure Plan, which

was formally adopted by the City of Greater Geelong in April 2011.

Figure 2-1 illustrates the locality of the subject site, and Figure 2-2 shows the location of the site in the

context of the Lara Structure Plan.

The site is currently zoned Rural Living and generally comprises rural lifestyle and low density residential

uses. Other land uses in the vicinity is typically rural residential in nature, with the Lara local neighbourhood

town centre located approximately 2.6 kilometres to the east. To the southwest of the subject site is the

Elcho Park Reserve and Elcho Park Golf Course is located to the south of Elcho Road.

To the west of the subject site, the land is also known as the Lara West Growth Area which is affected by

Amendment C246. This amendment proposes to rezone the land to the Urban Growth Zone, accompanied

by a Precinct Structure Plan, Native Vegetation Precinct Plan and Development Contributions Plan Overlay.

A Panel Report considering Amendment C246 was released in July 2013.

2.2 Road Network

2.2.1 Manzeene Avenue

Manzeene Avenue is generally aligned in a north-south direction, and provides a connection between Kees

Road in the north and Patullos Road in the south. Manzeene Avenue splits the subject site and has a

pavement width of approximately 6 metres and operates as a single carriageway providing for one traffic

lane in each direction, within a 20 metre road reserve.

Manzeene Avenue looking north from Patullos Road is shown in Figure 2-4.

Figure 2-4 Manzeene Avenue looking north from Patullos Road



2.2.2 Patullos Road

Patullos Road is a local road between Bacchus Marsh Road and Elcho Road. To the east of Elcho Road

along the frontage of the site, Patullos Road is classified as a major road and provides for a single lane of

traffic in each direction within a wide road reserve.

In the vicinity of the subject land, Patullos Road comprises a sealed pavement of approximately 7.5 metres,

within a large road reserve of approximately 62 metres. A speed limit of 80km/h applies on Patullos Road at

the frontage of the subject site.

Patullos Road looking east from Manzeene Avenue and O’Hallorans Road is shown in Figure 2-5 and Figure

2-6.

Figure 2-5 Patullos Road looking east from Manzeene Avenue



Figure 2-6 Patullos Road looking east from O’Hallorans Road



2.2.3 Kees Road

Kees Road is a local road connecting Windermere Road in the north and Patullos Road in the south. In the

vicinity of the subject land, Kees Road comprises a sealed pavement of approximately 3.4 metres, within a

large road reserve of approximately 64 metres.

Towards the eastern end of Patullos Road, Kees Road widens to provide 1 traffic lane in each direction and

a service road which provides direct access to adjoining lots. This leaves a significant verge between the

service road and the main carriageway.

Kees Road along the frontage of the site is shown in Figure 2-7.

Figure 2-7 Kees Road looking east from the subject site



2.2.4 Windermere Road

Windermere Road is a collector road providing access from Bacchus Marsh Road in the west through to Mill

Road in the east.

In the vicinity of the subject land, Windermere Road has a sealed pavement of approximately 7 metres

providing 1 trafficable lane in each direction within a 20 metre road reserve.

Windermere Road along the frontage of the site is shown in Figure 2-8.

Figure 2-8 Windermere Road looking east from the subject site



2.2.5 O’Hallorans Road

O’Hallorans Road is an unsealed rural road, connecting Windermere Road in the north and Canterbury Road

west in the south, from where it continues as Minyip Road to Bacchus Marsh Road. In the vicinity of the

subject land, O’Hallorans Road has a gravel road of approximately 6 metres providing 1 lane in each

direction, within a 20 metre road reserve.

It is understood that as part of the Lara West Growth Area, it is proposed to upgrade O’Hallorans Road, and

the intersection of Patullos Road and O’Hallorans Road is to be controlled by a traffic signals. The

O’Hallorans Road upgrade is not part

Figure 2-9 O’Hallorans Road looking south from Windermere Road



2.3 Public Transport

The site has reasonable access to public transport with a bus route operating on Patullos Road within

walking distance from the site. This bus service is listed in Table 2-1 and the bus routes are illustrated in

Figure 2-10.

Table 2-1 Available Public Transport Services

Service Route No Nearest Stop Route

Bus 12 Patullos Road Geelong City - Lara

It is also noted that the subject site is located within the study area of the G21 Integrated Public Transport

Strategy, which has identified improvements to the Route 12 bus service. These improvements include

providing morning and afternoon peak service to Lara, and expand services to cater for residential growth

areas.

Figure 2-10 Geelong Bus Routes

In addition to the bus service detailed above, the site is located approximately 3km to the west of the Lara Railway Station which provides access to a number of V/Line railway services. Travel times between Lara and Geelong generally is less than 18 minutes, whilst travel times between Lara and Melbourne is approximately 1 hour.

Subject Site



3 Lara West Growth Area

3.1 General

Land to the west of the subject site opposite O’Hallorans Road is also known as the Lara West Growth Area,

which covers approximately 380 hectares. The preliminary urban structure plan prepared for this land

indicates that it would include up to 4,000 residential lots, with a range of community and commercial

facilities including a neighbourhood activity centre, employment precinct, primary and secondary schools and

recreational areas.

A Panel Report considering Amendment C246 was released in July 2013.

Access to the Lara West Growth Area is proposed via the site frontages along O’Hallorans Road,

Windermere Road, Patullos Road and Bacchus Marsh Road, as shown in Figure 3-1.

Figure 3-1 Lara West Growth Area Preliminary Urban Structure Plan

Subject Site



3.2 Lara West Growth Area Traffic Volumes

A traffic report was prepared by O’Brien Traffic (dated 12 June 2012) for the development of the Lara West

Growth Area, and included detailed survey results of peak hour turning movement counts in the vicinity of

the subject site on Wednesday 4 May 2011 between 7am-9:30am and 4:30pm-7pm.

The location of the traffic surveys is illustrated in Figure 3-2, with the detailed survey results on Windermere

Road and Elcho Road shown in Figure 3-3 to Figure 3-6.

3.3 Lara West Growth Area Traffic Model

A traffic model was prepared by O’Brien Traffic for the development of the land within Lara West Growth

Area, which was developed in conjunction with Council and Vic Roads.

For the purposes of the traffic analysis, the interim traffic model in year 2022 was selected for future travel

demand forecast. The peak hour volumes for the Lara West Growth Area in 2022 during the AM and PM

peak are shown in Figure 3-7 and Figure 3-8 respectively, and Figure 3-9 illustrates the anticipated external

traffic distribution to the external road network.

In the Lara West Growth Area traffic model, the estimated peak hour traffic volumes were based on existing

traffic volumes and an annual growth factor of 4 per cent per annum.

Figure 3-9 Anticipated External Traffic Distribution Prepared by O’Brien Traffic



4 Proposed Amendment

4.1 General

Based on the development concept plan prepared by Spiire (Project Ref: 137580, Version 3), it is proposed

to rezone the subject site along both sides of Manzeene Avenue from Rural Living to the General Residential

Zone. The concept plan envisages a mix of conventional and medium density residential dwellings.

Based on the land area of approximately 60 hectares, it is projected the subject site could potentially

accommodate in the order of 600 lots assuming development of 10 lots per hectare. This estimation is

considered conservative and provides an appropriate base for the purposes of this traffic assessment.

The southwest corner of the subject site, has been identified as a possible site for non-residential uses such

as hotel, food and drink premises and service station. For the purposes of this report a maximum floor area

of 6,000 square metres has been assumed.

With regard to vehicle access, Manzeene Avenue will serve as the main road thorough the site with

connections to Kees Road in the north and Patullos Road in the south. With respect to O’Hallorans Road,

there is the opportunity to provide access to O’Hallorans Road with lots fronting O’Hallorans Road gaining

direct access.

The plan also shows the opportunity for future local connections to abutting land at 145 Patullos Road to the

south. Figure 4-1 illustrates the proposed residential subdivision lot layout and site access points to the

wider area.

Figure 4-1 Proposed Residential Subdivision Layout

145 Patullos Road



4.2 External Access

4.2.1 Interim Site Access

The development plan illustrates 2 primary access points to the subject land from Patullos Road and Kees

Road. In the interim, these primary site access points will allow fully directional access with the provision of

localised widening to facilitate turning movements.

In addition, road connections to the west via O’Hallorans Road are also available.

4.2.2 Ultimate Site Access

The Lara West Growth Area contemplates the upgrade of the key intersections in the vicinity of the subject

site, with localised widening to provide separate turning lanes.

In particular, it is proposed to construct traffic signals at the Patullos Road/ O’Hallorans Road intersection,

and realign the existing T-intersection of Patullos Road/ Elcho Road. In the future, it is expected that Patullos

Road/ O’Hallorans Road intersection will operate with 2 traffic lanes in each direction.

To the north, the O’Hallorans Road and Windermere Road intersection will also be upgraded to include

localised widening to provide a turning lane and an eastbound overtaking lane.

Conceptual functional layout plans illustrating the above intersection treatments are attached in Appendix A,

which were prepared by Smec Urban.

In O’Hallorans Road, it is understood that a 9 metres wide single carriageway will be constructed to

accommodate a traffic lane in each direction. At key intersections, O’Hallorans will be widened to provide

auxiliary right and left turning lanes to access the subject site.

4.3 Internal Road Network

The internal road network proposes a main access road (Manzeene Avenue) aligned in a north – south

direction within a 20 metres wide road reserve, with access streets branching off in an east-west direction.

All roads within the subdivision will be designed to provide for convenient access to individual allotments,

with road reservations typically 16 metres wide which is sufficient to provide for standard residential 7.3

metre wide road pavements.



5 Traffic Considerations

5.1 Traffic Generation

Traffic Modelling of the Lara West PSP area was undertaken by O’Brien Traffic (OBT) in their ‘Proposed

Development Lara West Growth Area Transport Assessment’ report dated June 2012.

Table 3 of the OBT report outlines the estimated traffic generation of the Lara West Growth Area and is

reproduced as Table 5-1.

Table 5-1 OBT Anticipated Traffic Generation for Lara West PSP

5.1.2 Residential

The ‘Lara West Growth Area Traffic and Transport Impact Assessment’ dated 21 June 2012, prepared by

O’Brien Traffic, adopted a peak hour traffic generation rate of 0.8 vehicle movement per hour for standard

residential lots, or approximately 8 vehicle movements per day per lot.

Based on the above and assuming the subject land is developed for in the order of 600 dwellings, it is

projected that such a development would generate 4,800 vehicle movements per day, inclusive of 480

vehicle movements in each peak hour.

Based on the above, a total of 480 vehicle movements are expected to be generated to and from the land

during each peak hour.

For residential subdivisions however, not all trips are external trips, with internal trips generally comprising local shopping and social visits.

The Victorian Integrated Survey of Travel and Activity 2007 (VISTA 07) is a survey of personal travel by

residents of Melbourne, Geelong and the regional centres of Ballarat, Bendigo, Shepparton and Latrobe,

undertaken by the Department of Transport in 2007 and 2008.



To assist in the distribution of residential traffic, VISTA 07 survey results were sourced for the outer

metropolitan areas, to determine the percentage of residential trips which are local shopping trips. The

results of the VISTA 07 surveys suggest that 6% of vehicle trips during the AM peak hour are shopping trips,

18% of vehicle trips during the PM peak hour are shopping trips and 20% of vehicle trips across the day are

are shopping trips.

Based on the foregoing, for the purposes of this assessment it will be assumed that 6% of residential trips

during the morning peak hour are internal trips, 18% of residential residential trips during the afternoon peak

hour are internal trips and 20% of residential trips across the day are internal trips.

Application of the above equates to 29 of the generated trips during the AM peak being internal, 86 of the generated trips during the PM peak being internal and 960 of the generated daily trips being internal. As such, the residential component is expected to generate 451 vehicle movements and 394 vehicle movements during the AM and PM peaks respectively and 3,840 daily vehicle movements.

Studies of residential developments indicate that during the morning peak hour approximately 20% of

movements are arrivals and 80% departures, whilst during the evening peak hour 60% of movements are

arrivals and 40% departures. The internal shopping trips however, are expected to comprise 40% inbound

trips during the AM peak and be evenly split between inbound and outbound movements during the PM

peak, in line with the anticipated shopping distributions. A summary of the anticipated traffic generated by the

residential component is provided in Table 5-2, Table 5-3 and Table 5-4 for total trips, internal trips and

external trips respectively.

Table 5-2 Peak Hour Traffic Movements – Total Residential Trips

Daily - - 4,800

Table 5-3 Peak Hour Traffic Movements – Internal Residential Trips





Daily - - 960

Table 5-4 Peak Hour Traffic Movements – External Residential Trips





Daily - - 3,840

5.1.3 Non-residential uses

For the purpose of this assessment, it is expected the critical time for traffic generation of non-residential

uses will be in the afternoon PM peak hour.

Based on the rates adopted in the Lara West Growth Area, it is estimated that the non-residential uses will

generate traffic at an average rate of 90 movements per 100 square metres per day, and 9 movements per

100 square metres in the PM peak hour. During the AM peak it is estimated that the traffic generation will be

10% of the PM peak, or 0.9 movements per 100 square metres.



Application of the above rate results in a projected daily traffic generation of 5,400 movements for the floor

area of 6,000 square metres, including 54 vehicle movements during the AM peak and 540 movements in

the PM peak hour. Of this traffic, 29 of the generated trips during the AM peak, 86 of the generated trips

during the PM peak and 960 of the generated daily trips have already been considered as shopping trips in

the residential traffic generation.

Therefore, it is projected that non-residential uses as proposed within the southwest corner of the site would

generate 25 vehicle movements to the external road network during the AM peak, 454 vehicle movements to

the external road network during the PM peak and 4,440 vehicle movements to the external road network

across the day.

For the purposes of this assessment it will be assumed that 60% of vehicle movements are inbound during

the AM peak and that vehicle movements are evenly split between inbound and outbound during the PM

peak. A summary of the anticipated traffic generated by the non-residential component is provided in Table

5-5, Table 5-6 and Table 5-7 for total trips, internal trips and external trips respectively. The internal trips

listed within Table 5-6 are the same trips listed in Table 5-3 and as such, should not be considered twice in

the assessment of the total traffic generation of the site.

Based on the foregoing, the development is anticipated to generate 476 vehicle movements and 848 vehicle

movements during the AM and PM peaks respectively and 8,280 daily vehicle movements. A summary of the

total trips generated by the proposal is provided in Table 5-8, broken up into internal trips in Table 5-9 and

external trips in Table 5-10.

5.2 Traffic Distribution

In consideration of the recorded traffic volumes, the following will be assumed with regard to distribution of

residential traffic.

▪ 15% of external traffic will be to / from the north along O’Hallorans Road. ▪ 15% of external traffic will be to / from the south along O’Hallorans Road. ▪ 20% of external traffic will be to / from the north along Manzeene Avenue. ▪ 50% of external traffic will be to / from the south along Manzeene Avenue. ▪ To the wider road network, approximately 30% of the traffic will have origins/destinations to the west

and 70% of the traffic will have origins/destinations to the east.

With regard to the non-residential use, it is expected that more people will utilise the higher order road, that

is, O’Hallorans Road and as such, the following distributions will be assumed.

▪ 35% of external traffic will be to / from the north along O’Hallorans Road. ▪ 35% of external traffic will be to / from the south along O’Hallorans Road. ▪ 10% of external traffic will be to / from the north along Manzeene Avenue. ▪ 20% of external traffic will be to / from the south along Manzeene Avenue. ▪ To the wider road network, approximately 30% of the traffic will have origins/destinations to the west

and 70% of the traffic will have origins/destinations to the east. ▪ Drivers with destinations to the west will use O’Hallorans Road.

Based on the foregoing, Figure 5-1 and Figure 5-2 have been prepared to illustrate the anticipated

development traffic distribution to Patullos Road, O’Hallorans Road and Kees Road for the residential and

non-residential use respectively, whilst Figure 5-3 illustrates the expected development daily volumes in the

vicinity of the subject site. Figure 5-4 illustrates the resultant peak hour volumes.

5.3 Other Developments

Review of the draft Precinct Structure Plan for the Lara West Growth Area and associated traffic report

indicates that the development to the west of the site is projected to generate in the order of 28,000

movements per day, assuming that a proportion of external trips will be multi-purpose trips.

Figure 5-5 illustrates the projected daily post development traffic volumes associated with the Lara West

Growth Area development, and the surrounding road network.

Figure 5-5 Lara West Growth Area Projected Post Development Traffic Volumes

The Lara West Growth Area traffic analysis indicates that O’Hallorans Road north of Patullos Road would be

expected to carry between 2,000 and 5,800 vehicles per day. To the south, Patullos Road is estimated to

carry 14,500 vehicles per day, whilst to the north Windermere Road is projected to carry 5,200 vehicles per

day.



5.4 Resultant Post Development Daily Traffic Volumes

The anticipated post development daily traffic volumes are summarised in Table 5-11, based on the

anticipated generation of the Lara West Growth Area in Figure 3-9, the anticipated generation of the

proposal in Figure 5-3 and the traffic volumes anticipated post the development of the Lara West Growth

Area shown in Figure 5-5. Existing volumes have generally been determined by subtracting volumes in

Figure 3-9 from volumes in Figure 5-5.

Figure 5-6 illustrates the external and resultant daily traffic volumes on O’Hallorans Road and Manzeene

Avenue.

5.5 Traffic Impact

5.5.1 Manzeene Avenue

Manzeene Avenue can be defined within the Greater Geelong Planning Scheme as a Level 2 Access Street,

which as a guide has an indicative maximum daily volume of 3,000 vehicles per day.

The proposed development is anticipated to generate a daily volume of 2,810 vehicle movements in

Manzeene Avenue. Based on this, Manzeene Avenue has sufficient capacity to accommodate the traffic

generated from the development of approximately 600 dwellings.

5.5.2 O’Hallorans Road

Traffic volumes in O’Hallorans Road will increase significantly as development occurs at the Lara West

Growth Area and to a lesser extent within the subject site. At the completion of these developments, it is

projected that O’Hallorans Road will carry up to 7,880 vehicles per day. Therefore, the proposed upgrade of

O’Hallorans Road will have sufficient capacity to accommodate the projected traffic volumes.

5.5.3 Kees Road

Based on the expected daily traffic generated by the site, Kees Road would carry in the order of 1,980

vehicle movements per day following the completion of the development.

Therefore, future volumes on Kees Road are typical of Level 1 Access Street, of which volumes in the range

of 1,000 to 2,000 vehicles per day are suggested within Clause 56 of the Geelong Planning Scheme.

In the vicinity of the subject site, Kees Road operates with a sealed pavement of approximately 3.4 metres

within a large road reserve. To accommodate the projected future traffic volumes (including those from Lara

West), it is recommended that Kees Road be widened to provide 1 traffic lane in each direction between

Windermere Road and Benjamin Drive. Upgrade of Kees Road should be shared between Lara West and

Manzeene.

In the context of existing traffic volumes, the widening of Kees Road will adequately accommodate the

anticipated peak demands.

5.5.4 Patullos Road and Manzeene Avenue Intersection

For the purposes of this assessment, it will be presumed that the interim access strategy will incorporate

localised widening at the Patullos Road and Manzeene Avenue intersection to provide auxiliary right and left

turning lanes to access the site.

A concept functional layout illustrating the proposed interim access arrangements is provided in Figure 5-7.

Figure 5-7 Patullos Road and Manzeene Avenue Intersection Concept Layout

Figure 5-8 has been prepared to illustrate the resultant 2022 peak hour volumes.



Figure 5-8 Patullos Road and Manzeene Avenue Intersection Peak Hour Volumes (2022)

To determine the impact of the proposed development, the traffic volumes detailed in Figure 5-8 and the

proposed Patullos Road and Manzeene Avenue intersection have been input into SIDRA and analysed.

SIDRA, a computer package originally developed by the Australian Road Research Board, as a guide for

intersection design has been used to assess the operation of the proposed intersections. The package

provides information about the capacity, average delay and 95th percentile back of queue of an intersection,

as described below.

Degree of Saturation (DOS) is the ratio of the volume of traffic observed making a particular movement

compared to the maximum capacity for that movement. Various values of degree of saturation and their

rating are shown in Table 5-12.

Table 5-12 Rating of Degrees of Saturation

Degree of Saturation Rating

Up to 0.6 Excellent

0.6 to 0.7 Very Good

0.7 to 0.8 Good

0.8 to 0.9 Fair

0.9 to 1.0 Poor

Above 1.0 Very Poor

Whilst rated as ‘poor’, it is considered acceptable for some critical movements in an intersection to operate in

the range of 0.9 to 1.0 during the high peak periods, reflecting actual conditions in a significant proportion of

suburban signalised intersections.

The 95th Percentile (95%ile) Queue represents the maximum queue length, in metres, that can be

expected in 95% of observed queue lengths in the peak hour.

Average Delay (seconds) is the delay time that can be expected for all vehicles making a particular

movement in the peak hour.

The results of the SIDRA analysis are summarised in Table 5-13, and they highlight that the Patullos Road

and Manzeene Avenue intersection is expected to operate under ‘good’ conditions after the completion of

the proposed development.

As shown in Figure 5-8, there is a significant level of through traffic carried during the peak periods on

Patullos Road in 2022 due to the development of the Lara West Growth Area. Accordingly, the SIDRA output

indicates delays in the order of 170 seconds will be experienced by motorists turning right out of Manzeene

Avenue in the afternoon peak hour.

Patullos Rd W (L) 0.01 8 0 0.03 8 0

Patullos Rd W (T) 0.74 0 0 0.46 0 0

Notwithstanding the above, it is anticipated that Patullos Road will experience a high level of platooning when the proposed traffic signals are constructed at the Patullos Road and O’Hallorans Road intersection. As such, it is considered that the projected delay for the right turn movements exiting out of Manzeene Avenue is overstated. This is highlighted by the degree of saturation and the modest queue distance. Based on this it is considered that the intersection will operate satisfactorily.

5.5.5 Patullos Road and O’Hallorans Road Intersection

It is proposed to construct traffic signals at the Patullos Road and O’Hallorans Road intersection, prior to the

development of the Lara West Growth Area. A concept functional layout illustrating the ultimate access

arrangement is provided in Figure 5-9.

Figure 5-10 has also been prepared to illustrate the resultant 2022 peak hour volumes at the Patullos Road

and O’Hallorans Road intersection, and Table 5-14 shows the results of the SIDRA intersection analysis.

The results of the SIDRA analysis highlight that the Patullos Road and O’Hallorans Road intersection is

expected to operate under ‘good’ conditions after the completion of the proposed development in 2022.

5.5.6 O’Hallorans Road and Windermere Road Intersection

The O’Hallorans Road and Windermere Road intersection is proposed to be upgraded with localised road

widening to accommodate right turning movements into O’Hallorans Road, and an eastbound overtaking

lane. A concept functional layout illustrating the above ultimate access arrangement is provided in Figure 5-

11.

The above analysis indicates that at the full development of the subject site in 2022, the O’Hallorans Road

and Windermere Road intersection will operate within the ‘excellent’ category with negligible queues and

delays to motorists departing the subject site, highlighting that the proposed improvement works would be an

acceptable intersection treatment.



6 Internal Road Layout

At this stage a road layout for the subdivision has not been established. It is recommended that in general

terms, all road cross sections be designed in accordance with Clause 56 of the Planning Scheme with due

reference to the GAA guidelines.

7 Conclusions

Based on the preceding analysis, it is concluded that:

▪ Development of 600 dwellings within the subject site would generate in the order of 4,800 vehicle movements per day, and 480 vehicle movements occurring during the peak periods.

▪ The non-residential uses as proposed is projected to generate approximately 5,400 vehicle movements per day, and 540 movements in the PM peak hour.

▪ Generated traffic will be distributed to both the surrounding local road network and directly to Manzeene Avenue and O’Hallorans Road.

▪ Daily traffic volumes in Manzeene Avenue would carry in the order of 2,810 vehicles per day, which is within the targeted range for a street of this function and nature.

▪ At the completion of the proposed Manzeene Avenue subdivision and the Lara West Growth Area, Patullos Road east of Manzeene Avenue is projected to carry approximately 18,000 vehicles per day, and Windermere Road east of Kees Road will carry in the order of 7,000 vehicles per day. Kees Road will carry approximately 2,000 vehicles per day.

▪ The additional traffic volumes on Patullos Road and Windermere Road would be adequately accommodated within the existing carriageway.

▪ With regard to O’Hallorans Road and Kees Road, the proposed improvement works will adequately accommodate the projected traffic volumes.

▪ The proposed intersection treatments at Patullos Road/ Manzeene Avenue, Patullos Road/ O’Hallorans Road, and O’Hallorans Road/ Windermere Road will provide for safe and efficient site access.

▪ There are no traffic engineering grounds that should prohibit the rezoning of the land to the General Residential Zone.
