1. Introduction

Cleanaway are applying for the reconstruction of the Materials Recovery Facility on Lot 62 Hyne Road in South

Guildford. Planning Solutions on behalf of Cleanaway, have requested a Transport Impact Assessment to support

the Development Application.

The local council is the City of Swan. The site location is shown in Figure 1. Figure 2 is an aerial photo of the

site and the previous facility before a fire occurred at the site in late 2019.

2. Proposed Development

2.1. Proposed Use

From May 2017 to November 2019, the site was used as a Material Recovery Facility which received and

processed recyclable waste from numerous local councils in Western Australia. Once reconstructed, the same

operations will resume. The site will include a tipping area, a production area, a finished product store, an office,

an education room, a weighbridge and parking areas for cars and trucks.

A maximum of 60 employees are expected to be on site each day based on two shifts with 30 employees during

each shift. Additionally up to 20 customers or visitors can be accommodated in the education room.

A site plan is shown in Figure 3.

3. Vehicle Access and Parking

3.1. Proposed Access and Parking

The access arrangements will not change. Truck access is via two crossovers at each end of the site. Light

vehicle access is via a full movement crossover located between the truck crossovers which leads to the car park.

A total of 90 car bays and 39 truck bays are proposed on the site. The vehicle access and parking layout is shown

in Figure 4.

3.2. Car Parking Supply

The requirements for car parking have been assessed for compliance with the City of Swan Local Planning Policy

POL-TP-129 Vehicle Parking Standards as outlined in Table 1. The POL-TP-129 land uses applied are consistent

with the previous application that was approved in 2016.

Table 1: Car Parking Calculation

1 space per person employed;

whichever is greater

2,500m2 GLA 25

Total Required 273

Total Provided 90

Shortfall or Surplus -183

As shown, the parking provision is significantly short of the requirements as calculated based on the Gross

Leasable Area. It is noted that the actual parking demand for the facility is likely to be much less on the basis that

the facility will primarily generate staff trips, delivery trips and some customer/visitor trips.

As mentioned previously, an absolute maximum of 60 employees would be on site on any given day with a

maximum of 30 employees during each of the two working shifts. Assuming conservatively that all staff drive to

and from work individually, the peak parking demand for staff would be 60 bays which would occur at the shift

changeover. An additional 20 bays would be required for the maximum 20 customers or visitors, again assuming

that all would drive individually and attend the site at the same time as the shift changeover. Overall, the realistic

car parking demand is therefore estimated to be 80 spaces.

It is noted that site has sufficient hardstand space around the buildings to accommodate additional parking bays

if necessary to accommodate any future changes in operations. However, for the operations currently being

proposed, the provision of 90 car bays is considered to be adequate.

A review of historical aerial photography indicates that the available parking on the site has been adequate with

vacant bays on most days. Appendix A includes some aerial images from when the site was operating.

Figure 3.2 of AS2890.1, shown as Figure 5, prescribes the minimum required entering sight distance (ESD) for

access driveways based on varying approach speed of vehicles on the frontage road.

Figure 5: AS2890.1 Access Sight Distance Requirements

Based on the 50km/h speed limit along Hyne Road, the minimum required ESD from the exit crossovers is 45

metres (69 metres desirable). The available sight distance at each of the crossovers greatly exceeds the minimum

requirements due to the wide verges and lack of obstructions within the verge. Again, it is noted that Hyne Road

is a cul-de-sac and so the actual speeds along the Hyne Road adjacent to the crossovers is likely to be lower

than 50km/h.

4. Provision for Service Vehicles

The site is accessed by various service vehicles including collection trucks, 40ft trailer trucks, 40ft container

trucks, B-Doubles and others. As the site has accommodated these vehicles previously and will resume the same

operation, the accessibility for services vehicles has not been assessed further.

5. Hours of Operation

The facility will operate Mondays to Saturdays from 5am to 10pm. A maintenance team is also likely to work

overnight.

6. Daily Traffic Volumes

The volume of traffic generated by the facility has been calculated from statistics collected by Cleanaway when

the site was operating.

From December 2018 to November 2019, the site generated an average of 158 service vehicle trips per day.

These trips are assumed to be spread out relatively evenly throughout the day and so the trip generation during

the peak periods on the road network is likely to be in the order of 11 service vehicle trips per hour. Additionally,

the 60 staff are also likely to generate vehicle trips with these trips conservatively assumed to coincide with the

road network peak. Overall, the peak hour trip generation is estimated to be 71 vehicles per hour.

This volume of traffic is considered to have a low to moderate impact on the road network.

Due to the high proportion of heavy vehicles generated by the site and the surrounding developments, an

assessment of the peak hour operation of the Great Eastern Highway / Hyne Road intersection has been

undertaken in SIDRA Intersection 8.0.

The peak hour intersection flows were derived from traffic data obtained from Main Roads WA, the City of Swan

and manual traffic surveys undertaken by Shawmac. The results of the assessment are shown in Figure 6 and

Figure 7.

Figure 6: SIDRA Assessment Results – AM Peak Hour (7 to 8AM)

Figure 7: SIDRA Assessment Results – PM Peak Hour (4 to 5PM)

The results of the assessment suggest that there is insufficient capacity for vehicles turning right from Hyne Road

onto Great Eastern Highway, particularly during the afternoon peak hour.

In reality, the upstream and downstream signalised intersections at the Great Eastern Highway Bypass and

Kalamunda Road will have a platooning effect where the signals creates larger gaps in the traffic along Great

Eastern Highway on the approach to Hyne Road.

A review of the intersection operation during the afternoon peak hour in March 2020 indicated that the intersection

was operating within capacity with the right turn movement from Hyne Road experiencing low to moderate delays

and a maximum queue of approximately 5 vehicles.

7. Traffic Management on Frontage Streets

The details of the adjacent road network are summarised in Table 2.

Table 2: Road Configuration

Road and Location Road Type Cross Section Speed Limit

Hyne Road Access Road Single carriageway – 2 lanes 50 km/h

Great Eastern Highway Primary Distributor Single carriageway – 4 lanes 60 km/h

Although Hyne Road has a 50km/h speed limit, it is a cul-de-sac less than 500m long and so the typical vehicle

speeds are likely to be below 50km/h, particularly towards the cul-de-sac end of the road adjacent to the site.

Great Eastern Highway intersects with Hyne Road as a T- intersection under give-way control with priority along

Great Eastern Highway. The layout of the intersection is shown in Figure 8.

8. Public Transport Access

The site has some access to existing public transport services. The following Transperth bus routes currently

operate within reasonable walking distance of the site:

Route 36 between Perth and Midland Station

Route 299 between Perth and Walliston

Both routes have stops along Great Eastern Highway immediately north-west of Hyne Road, approximately 400

to 500m walking distance from the site.

Based on the proposed use, the demand for public transport is likely to be relatively low and so the existing

services are considered to be adequate.

12 | P a g e

9. Pedestrian and Cycle Access

There is limited pedestrian/cyclist infrastructure along Hyne Road with only short sections of paths in some areas.

This is considered to be typical of many industrial areas and developments where there is little or no demand for

pedestrian or cyclist access to and from the site.

13 | P a g e

10. Site Specific or Safety Issues

The crash history along Hyne Road for the five-year period ending December 2018 was obtained from the MRWA

Reporting Centre.

Only two crashes have been recorded along Hyne Road with both occurring at the intersection with Great Eastern

Highway and both being rear end crashes involving an eastbound light vehicle colliding with another light vehicle

turning right into Hyne Road. One crash occurred in 2015 during the weekend peak hour in wet conditions

resulting in property damage only. One crash occurred in 2018 during the morning peak hour in dry conditions

requiring medical attention.

The number of crashes is considered to be low and considering that the proposed operations will remain the

same as before, it is unlikely that the risk of crashes would increase as a result of the proposed development.

No other site specific or safety issues were identified.

14 | P a g e

11. Conclusion

A Transport Impact Statement of the proposed mixed use development concluded the following:

The proposed development is expected to have a minimal transport impact on the adjacent road network

and no modification to the network is recommended. It is noted that site has recently operated as a

Materials Recovery Facility and that the proposed operations will be the same as the previous operations.

A SIDRA assessment of the peak hour capacity at the Great Eastern Highway / Hyne Road intersection

suggests that there is insufficient capacity for vehicles turning right from Hyne Road onto Great Eastern

Highway, particularly during the afternoon peak hour. A site visit during the critical afternoon peak hour

confirms that the site is actually operating well within capacity due to the upstream traffic signals on either

side of Hyne Road having a platooning effect on the traffic approaching this intersection by creating larger

gaps than modelled by SIDRA.

The proposed car parking provision is considered to be adequate.

The accessibility for pedestrians and cyclists is considered to be adequate.

The existing available public transport services are considered to be adequate.

A review of the crash history did not identify any atypical crash patterns. The expected volume of traffic

generated by the development is not likely to increase the risk of crashes on the adjacent road network.
