1 Introduction
1.1 Background
Aurigen Group Limited (Aurigen) is a private waste service provider that specialises in a variety of
services to domestic, industrial and local government clients including resource recovery, waste
logistics, waste disposal and commodity aggregation and trading. Commodity aggregation refers to
the sorting and consolidation of recycled materials in order to prepare them for sale to markets.
Aurigen acquired a lease on 25 Jackson Street, Bassendean (the Site) in late 2015 where they propose
to develop a Waste Transfer and Resource Recovery Facility (the Proposed Development). This will be
an integrated Facility providing a range of recycling and waste management services reflective of
modern, advanced facilities.
Talis Consultants Pty Ltd (Talis) has been engaged by Aurigen to prepare a Traffic and Transport
Assessment (the Assessment) to determine the potential traffic impacts of operating the Facility on the
adjacent road network and also considers the traffic arrangements within the Site. This Assessment has
been requested by the Town of Bassendean (the Town) to support Aurigen’s planning approval sought
for the proposed Facility, in addition to the Environmental Assessment and Management Plan (EAMP).
Operation of the Facility will generate new inbound and outbound vehicle movements accessing the
Site and the Assessment provides evidence that this increase in traffic will not cause an unacceptable
impact to surrounding businesses and other road users.
1.2 Scope of the Report
This Traffic and Transport Assessment has been broadly prepared in general context with the Western
Australian Planning Commission’s (WAPC) Traffic Impact Assessment Guidelines, Volume 4: Individual
Developments (2016) to demonstrate to the Town that the Proposed Development will:
Provide safe and efficient access for all modes of traffic type which will be associated with the
proposed development;
Be well integrated with surrounding land uses;
Not adversely impact surrounding land uses; and
Not adversely impact surrounding transport networks and the users of those networks.

2 Site Information
The Site is located at 25 Jackson Street, Bassendean in the Bassendean Industrial Area within the
administrative boundary of the Town of Bassendean, approximately 10km from the centre of Perth.
The site is bordered by Jackson Street on its southwestern side with a separate access road to the Site
from Alice Street to the southeast of the Site. The location of the site is shown in Figure 1.
2.1 Surrounding Land Uses
The Site is located in the middle of an industrial zone that is comprised of the Bassendean (or Tonkin)
Industrial Area and the adjoining Bayswater Industrial Area to the west. Consistent with the zoning, the
area is characterised by numerous industrial businesses including manufacturing companies and
warehouses.
The closest residential area to the Site is located approximately 570m away to the north in the
neighbouring suburb of Bayswater (within the City of Bayswater). These residences are situated directly
adjacent to the northern extent of the industrial area, which extends onto the northern side of Collier
Road.
There are also a number of waste management facilities at which similar operations are undertaken
in the vicinity of the Site. Talis is of the opinion that this demonstrates that the Site is located within an
appropriate area for the proposed Facility.
2.2 Surrounding Road Network
The surrounding road network in the immediate vicinity of the Site includes Jackson Street and Alice
Street. Both Jackson Street and Alice Street are on the oversize Restricted Access Vehicle (RAV) network,
as defined by Main Roads Western Australia (MRWA). These streets are considered as RAV Network 2-7
(Main Roads WA) roads, which means that vehicles equal or up to 36.5m in length and up to a mass
of 107.5 tonne can utilise them. According to the MRWA Road Hierarchy, Jackson Street is classified
as a Local Distributor road and Alice Street and Wood Street are classified as Access Roads, all of
which have a speed limit of 50km/h.
2.2.1 Crash Blackspots
In preparation of this report, the Town’s Local Area Traffic Management (LATM) Plan (Opus, 2012) was
reviewed. The LATM Plan sets out local traffic issues and proposed measures to address these issues.
The intersection of Collier Road/Grey Street/Jackson Street was identified as a problematic crash site,
ranking No. 1 based on crash data from 2006 to 2010, which reported 47 collisions. The LATM Plan
indicated that this intersection was proposed for treatment with the construction of a dual lane
roundabout. The Town submitted a nomination for the construction of the roundabout at the Collier
Road/Grey Road/Jackson street intersection to MRWA in July 2012 and MRWA approved funding of the
project under their 2014/15 State Black Spot Program.
2.2.2 Speed on the Surrounding Road Network
The LATM Plan also analysed the incidence of speeding on local roads. Jackson Street, at its northern
end, Alice Street at its northern end and all of Wood Street were flagged as roads with over one quarter
(25%) of road users exceeding the speed limit and in the 85th percentile speeds of 5km or more over
the speed limit.

TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 3
2.3 Site Access
The Bassendean Industrial Area is conveniently located in close proximity to a number of major arterial
roads including Collier Road (approximately 100m to the north) and bordered by Railway
Parade/Guildford Road (approximately 750m to the south) and Tonkin Highway (approximately 415m
to the west), which is accessible via Collier or Guildford Roads.
There are three gated vehicle access points to the Site. Two of these are from the front of the Site on
Jackson Street, which are separated from each other by a security fence on a small embankment.
There is a third Site access point from a private access road on the adjacent Alice Street. Most of the
traffic will be dropping off or collecting commodities, recyclables or waste and will access the site via
the northern Jackson Street or Alice Street entrances. Both of these entry points will be equipped with
weighbridges. The Alice Street entry will also have a gatehouse.
Heavy vehicles will enter and exit the Site via two primary Site entrances, namely the northern Jackson
Street entrance and Alice Street entrance. The types of heavy vehicles that will drop-off and collect
waste and commodities are detailed in Table 2-1.
Table 2-1: Heavy vehicles accessing the Site during operation
Vehicle Type Capacity
Kerbside/Front Lift Collection vehicles 6-9 tonnes
Semi-trailers such as side loading 20 tonnes
B-doubles 60 tonnes
Given Waste Transfer and Resource Recovery are logistics operations, it is important that the Site is
easily accessible by road. The Site is in an excellent strategic location, in close proximity to major roads
including Collier Road (to the north) and Tonkin Highway (accessed via Collier Road) which provides
easy access to other associated facilities (e.g. port).
2.3.1 Staff Access
Staff, maintenance and visitor vehicles will enter the Site through the northern of the two Jackson Street
entrances to access the designated small vehicle car parking areas. The parking facilities on-site will
be upgraded to include provision for at least 40 parking bays, as shown in the Conceptual Site Plan
(Drawing G-001 in the EAMP). The number of inbound and outbound staff vehicles from the Site
assumes one vehicle per staff member. Aurigen forecast the fully developed site would operate with
thirty (30) staff members, with 10 parking bays allowed for visitors and maintenance vehicles. Aurigen
will encourage the employment of local people at the Facility, the use of public transport, car sharing,
or other sustainable forms of transport (cycling etc.). Therefore, it is anticipated that the staff vehicle
traffic volumes will be significantly less than those estimated in the Assessment.
2.3.2 Pedestrian and Cyclist Access and Networks
There are no pedestrian footpaths currently located along Jackson Street. However, the Site has
provision for pedestrians and cyclists to have direct access to the Site via the office, which is equipped
with a dedicated path accessible from Jackson Street, north of the two vehicle entrances (see
Conceptual Site Plan Drawing G-001).
According to the Department of Transport, Jackson Street is on the Perth Bicycle Network (

TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 4
Plate 2-1) which connects with cycling routes to the east (towards Bassendean), north (towards Morley),
west (towards Embleton) and south (towards Ashfield).
Plate 2-1: Perth Bicycle Network surrounding the Site
2.3.3 Public Transport Access
The closest train station to the Site is Ashfield station on the Perth to Midland line, which is approximately
12 minutes’ walk from the Site. The closest bus stop is on Collier Road where bus no. 955 runs between
Ellenbrook and Morley Bus Station.
2.4 On-site Parking
As mentioned above, there will be on-site parking provided for staff, maintenance and visitors. Details
of the parking including the type, number and dimensions are shown in Table 2-2. The dimensions for
car parking bays were allocated utilising of the following documents as guidance:
Town of Bassendean’s Local Planning Policy No. 8 – Parking Specifications; and
Australian Standard Parking facilities – Part 6: Off-street parking for people with disabilities.
The location of the car parking facilities are shown on the Conceptual Site Plan (Drawing G-001 in the
EAMP).
Table 2-2: Proposed on-site parking facilities
Type of Parking No. of bays Parking angle Dimensions per bay
Upgraded car park 17 0º or 90º 2.5m x 5.4m
Undercover parking 4 0º 2.5m x 2.5m

Disabled parking (with shared area) 2 90º 2.4m x 5.4m
TOTAL 40 - -
The designated small vehicle parking area is located between the Jackson Street entrance and the
main office, which accommodates 17 vehicles. There are an additional 3 parking spaces on the rear
side of the office, along with two accessible (disabled) parking spaces. An additional 14 parallel

parking bays along the north-west perimeter of the Site. The parking area will include an upgraded car
park, existing undercover parking and disabled parking facilities totalling 40 bays.
2.5 Loading and Unloading Areas
As shown in Drawings G301- G303, the designated loading and unloading areas are located in close
proximity to each of the Facility’s proposed operations. An undercover unloading area on the south-
eastern side of the Site next to the baler/shredder shed will enable vehicles to unload scrap metals
prior to baling/shredding and consolidation in the Metal Recovery Facility. Once consolidated, scrap
metal will be loaded into sea containers to the south-west of the Metal Recovery Facility ready for
collection and shipment to overseas markets. The Materials Recovery Facility (MRF) and Waste Transfer
Station (WTS) will have designated unloading areas (2 for the MRF and 3 for the WTS) inside the proposed
building to allow vehicles to reverse and unload their waste. The Baling Shed that will bale paper and
cardboard from the MRF will have a loading bay at its north-eastern end.
2.6 Environmental Noise
An Environmental Noise Assessment was undertaken for the Site by Lloyd George Acoustics (Lloyd
George) (full report in Appendix E of the EAMP). The Noise Assessment concluded the Site complies
with noise regulations during the daytime, Monday to Saturday 7:00 to 19:00. To operate the site on
Sundays and public holidays between 9:00 and 19:00, a 5dB reduction in noise would be required.
Noise from trucks currently utilising the site from the Alice Street entrance were predicted to generate
67dB, which after a 5dB penalty for tonal noise emissions, results in an assembled level of 71dB. The
assigned noise level for this industrial area during the day is 65dB. The assessment identified that a 6dB
exceedance must be mitigated to ensure compliance with noise requirements. Lloyd George
recommended that a noise wall be constructed along the east side of the ramp and a section of the
north east boundary to mitigate noise form trucks. Implementing this targeted noise controls is
anticipated to sufficiently reduce the environmental disturbance of any current or future traffic
movements to and from the Site.

3 Existing Traffic Volumes
As part of this analysis, two intersections were analysed including Jackson Street and Alice Street, as
well as Alice Street and Wood Street, as shown in Diagram 3-1. As mentioned previously, Jackson
Street is classified as a Local Distributor road and Alice Street and Wood Street are Access Roads, both
of which have a speed limit of 50km/h. These three roads surround the Site and will likely experience
the most direct impact of any increase in traffic volume due to the operation of the Facility.
No recent traffic data was available on these roads from MRWA or the Town of Bassendean. As a result,
in order to analyse current traffic movement, Talis performed a manual traffic count on these
intersections. The traffic count was performed between 10:00-11:00 on a weekday to gain an average
representation of peak traffic volumes. Based on advice from the client in relation to anticipated Site
traffic, peak periods of two hours duration are anticipated to occur on weekday mornings (9:00-11:00)
and afternoons (14:00-16:00).
Copies of the original manual count sheets have been attached in Appendix A. The results of the
manual traffic count are shown below in Diagram 3-1, where the number of vehicles passing and
percentage of heavy vehicles are displayed.
Diagram 3-1: Existing Weekday Traffic Flow with Heavy Vehicle Percentage over 1 hour (10:00 –
11:00)
The manual traffic count provided a breakdown of heavy vehicle traffic and overall volumes to be
determined for the hour in question. From these volumes, the traffic flows towards the two primary
Facility entrances can be calculated and used to determine traffic impact. The approach and exit
flow for each direction is shown below in Diagram 3-2.

Aurigen Group Ltd
TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 7
As expected, the highest volume of traffic was observed on Jackson Street, as this road creates a
direct connection between Collier Road and Railway Parade. At the time of the traffic count, none of
the traffic movements involved vehicles entering and exiting the Site as the Facility is operating with
limited traffic movements currently.

4 Development Proposal
Talis modelled the vehicle movements based on the quantity of waste and materials anticipated to
be accepted per annum at the Site along with the types of vehicles expected to carry loads. For
completeness, the incoming vehicles to the Waste Transfer Station (WTS) and Materials Recovery
Facility (MRF) are predicted to be primarily kerbside waste collection vehicles with a capacity of
approximately 9 tonnes. The incoming commodity drop-off vehicles may vary in capacity from 15 to
26 tonnes.
Table 4-1 sets out the anticipated daily vehicle movements to and from the Site based on the
following design capacities:
Material Recovery Facility of 100,000 tonnes per annum (tpa);
Commodity aggregation activities of up to 120,000 tpa; and
Waste Transfer Station with capacity for 100,000 tpa.
It is important to note that the calculations have assumed a seven day working week for waste
acceptance. In reality, fewer vehicles are expected on weekends than weekdays.

As shown in Table 4-1, the traffic data modelling indicates that there would be an estimated 161
vehicle movements or trucks dropping off and collecting waste and materials to and from the Site
during normal operating hours (06:00-18:30) along with 30 staff vehicles.
Traffic and Transport Assessment
Waste Transfer and Resource Recovery Facility, 25 Jackson St, Bassendean
Aurigen Group Ltd
TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 9
During each of the two hour peak periods occurring in the morning (09:00-11:00) and the afternoon
(14:00-16:00), the following predicted traffic volumes were utilised:
35% of total daily inbound MRF vehicles (16 vehicles);
35% of total daily inbound Putrescible WTS vehicles (11 vehicles);
Inbound Commodity drop-offs (8 vehicles); and
Even distribution of outbound traffic associated with commodity collections and compacted
putrescible waste removal (6 vehicles).
This equates to 41 vehicles over the two hour period or 20-21 vehicles over the one hour peak period.
This is a conservative ‘worst-case’ approach towards expected vehicle movements and volumes are
not anticipated to exceed these volumes. Commodity drop-offs and compaction haulage vehicle
movements are not anticipated to experience ‘peak periods’ and were modelled to arrive and depart
consistently over the duration of 12.5 hour working day.
Operational staff will be required to be present at the Site prior to waste vehicle arrivals and following
the end of the day, so it was assumed that staff vehicle traffic did not impact site operation vehicles
and was analysed separately. Designated staff car parking will also be provided for small vehicles (see
Section 2.4 for more information).
To determine the impact constructing the proposed Facility would have on the surrounding traffic
network, four scenarios were analysed and compared to current volumes, including:
Scenario 1: Jackson Street Entrance (Trucks Only);
Scenario 2: Alice Street Entrance (Trucks Only);
Scenario 3: Staff Arriving Jackson Street Entrance; and
Scenario 4: Staff Departing Jackson Street Entrance.
4.1 Assumptions
When modelling the scenarios, the following assumptions were made:
Manual traffic counts undertaken for one hour between 10:00-11:00 on a weekday on the
intersections of Jackson Street and Alice Street, as well as Alice Street and Wood Street is during
the morning peak period (09:00-11:00) expected at the Facility;
Half of the staff arrive and depart from the Site via Collier Road, whilst the other half arrive and
depart from Railway Parade;
The model assumes that all staff will drive to work and each drive their own vehicle. In reality,
there is potential for staff to carpool, cycle or use public transport with a dedicated pedestrian
and cyclist access gate off Jackson Street; and
Half of the vehicle movements or trucks dropping off and collecting waste will utilise the
Jackson Street entrance, arriving from and departing towards Collier Road, whilst the other half
of vehicles movements or trucks are anticipated to access the Site via Alice Street utilising the
Alice Street and Collier Road access point.
4.2 SIDRA Analysis
In order to assess the operation of the intersections and the impact of additional traffic, analysis was
undertaken using SIDRA INTERSECTION 5.0 (SIDRA), a software package utilised for intersection design
and modelling network capacity.
Traffic and Transport Assessment
Waste Transfer and Resource Recovery Facility, 25 Jackson St, Bassendean
Aurigen Group Ltd
TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 10
SIDRA creates a model based on the lane geometry and traffic volumes and provides a number of
outputs including, but not limited to:
Degree of Saturation: the ratio of demand to capacity on the approach to the intersection;
Average Delay: average of all time delays of vehicles travelling through the intersection; and
Average Speed.
One of the key outputs of the SIDRA analysis is the Level of Service for each approach to the
intersection. Level of Service (LOS) is a qualitative measure used to describe the operating conditions
of a roadway. By performing an analysis of current conditions and predicted traffic, the Level of Service
provides a means of comparison to easily identify overall impact to the intersection. An explanation
of the different Level of Service ratings is shown below in Table 4-2.
Table 4-2: Level of Service Ratings
Level of Service Rating Traffic Condition
LOS A Excellent Free flowing
LOS B Very good Stable flow with minimal delays
LOS C Good Stable with restricted movement
LOS D Fair Movement more restricted
LOS E Poor Traffic is congested with long queues and delays
LOS F Very Poor Traffic demand exceeds intersection capacity
The current traffic volumes, as discussed in Section 3, were modelled in SIDRA to allow a comparison
to be made against the predicted conditions. The results of the analysis are shown below in Table 4-3
including left (L), right (R) and through (T) traffic movements. Output calculations from the SIDRA
modelling are presented in Appendix C.

As shown in Table 4-3, the current traffic movements of both intersections are categorised as LOS A
(Excellent) in all directions. Traffic is freely flowing and there are no significant delays experienced by
any of the flow directions.
4.3 Impact on Scenario 1 and 2
When introducing the Facility’s operations into the analysis, the impact of the additional traffic on the
existing volumes entering and exiting the Site could be determined through the SIDRA modelling
process, as shown in Table 4-4.

In Scenario 1, the north-west and south-east approaches of Jackson Street experienced no change
to their Level of Service. The only changes appear to affect vehicles exiting the Facility from the
Jackson Street access point turning left (LOS B) and turning right (LOS C), of which only the right turning
vehicles are relevant as vehicles are expected to exit towards Collier Road for Tonkin Highway. The
SIDRA modelling has determined that only vehicles entering and exiting the Facility are going to
experience any sort of delay, with maximum average delays expected to be up to 21.9 seconds. The
entrance has sufficient space for one B-double, the longest vehicle accessing the Site, to queue on
the access road.
With respect to the SIDRA modelling for Scenario 2, all directions of traffic are classified as LOS A,
except for the vehicles entering the Facility turning right from Alice Street. The only vehicles subject to
any delays for Scenario 2 are the vehicles entering the Facility with maximum average delays
Traffic and Transport Assessment

TW15042 - Traffic and Transport Assessment.1b December 2016 | Page 12
expected to be up to 11.3 seconds. The Alice Street entrance also has sufficient space for one B-
double, the longest vehicle accessing the Site, to queue on the access road.
4.4 Impact on Scenario 3 and 4
The traffic conditions under Scenario 3, when staff arrive at the start of the day (pre-peak) and Scenario
4, when the staff leave at the end of the day (post-peak), in conjunction with the current traffic volumes
is summarised in Table 4-5 below. These movements were modelled on a conservative basis
assuming that morning and afternoon traffic volumes are the same as the Facility’s peak period. In
reality, the traffic volumes at these times will be much lower.

All volumes under these scenarios still maintain the same level of service (LOS A) as the current traffic
conditions. The office and parking areas are located on the Jackson Street side of the Site. All staff
vehicles will enter the Site through the Jackson Street (small vehicle) entrance.
4.5 Committed Developments
4.5.1 Lot 10 – Railway Parade, Bayswater
As part of the Assessment, the Town requested that the Outline Development & Subdivision Concept
Plan – Eastern Access Assessment (Concept Plan) be considered. The Concept Plan was prepared in
relation to a development of vacant industrial land located at Lot 10 Railway Parade, Bayswater, south
of the Site. This plan includes a new access point onto Tonkin Highway, a full movement access point
on Railway Parade and construction of Vincent Street and Wicks Street, with a roundabout at its
intersection with Jackson Street.
The Concept Plan reports on the preferred eastern road connection to the development. The preferred
connection was found to be the proposed new road, Wick Street, onto Jackson Street with provision

of a new roundabout, at this intersection. The Concept Plan states that traffic would be anticipated to
utilise Jackson Street to access Tonkin Highway however, no vehicle movements are quantified within
the Concept Plan. Traffic produced as a result of this development is expected to interact with traffic
volumes surrounding the Site. However, all vehicles accessing the Site during operations will access
and depart the Site utilising Jackson Street and Collier Road or Alice Street and Collier Road for Tonkin
Highway and are not anticipated to utilise Railway Parade or the new Wick Street/Jackson Street
intersection.
4.6 On-site Vehicle Movements
4.6.1 Turning Path Movements
Vehicle movement mapping was performed for a kerbside collection vehicle, B-double and semi-
trailer as shown in Drawings G-301- G-303 in Appendix B. These turning path movements demonstrate
that the Site has sufficient capacity for all vehicles types modelled to manoeuvre between the loading
and unloading areas, and still enter and exit the Site without major obstruction.
4.6.2 Traffic Safety on-site
A number of management measures will be adopted on-site to safely manage traffic including:
Vehicles will be restricted to a maximum speed of 10km/hour whilst on the Site which will be
signposted at appropriate locations including the entrance to the Site;
Signage providing Site directions, traffic control measures and safety instructions will be
established and maintained at appropriate locations around the Site;
There will be adequate staff supervision to ensure staff safety around moving vehicles; and
Employees and contractors shall wear high visibility and reflective clothing when working in
areas where vehicle movement occurs.
Further information in relation to traffic management on-site can be found in the EAMP.

5 Conclusions
The conclusions of the Traffic and Transport Assessment are as follows:
The current traffic volumes on the road network surrounding the Site will experience minimal
impact due to the predicted traffic movements during the Facility’s peak periods.
The development of the proposed Facility will generate an estimated 161 heavy vehicle and
30 staff vehicle two-way movements (into and out of the Site) each day under the ‘worst-case’
scenario.
Up to 70% of the total heavy vehicle traffic is expected during the morning and afternoon
peak periods between 09:00-11:00 and 14:00-16:00 for Materials Recovery Facility and Waste
Transfer Station drop-offs. This would result in up to 41 vehicle movements per hour with these
vehicles utilising Jackson Street and Alice Street to access the Site and Collier Road.
Turning path movements undertaken demonstrate that the Site has sufficient capacity for all
vehicle types modelled to manoeuvre between the various loading and unloading points,
and still enter and exit the Site without major obstruction.
SIDRA analysis of the two Site entrances determined that these intersections have sufficient
operational capacity for the Facility’s vehicle movements.
The modelling indicates that the only delays created due to the additional traffic associated
with the Site would be experienced by those vehicles entering and exiting the Site with
maximum average delays expected to be up to 21.9 seconds. Both entrances have sufficient
space for one B-double, the longest vehicle accessing the Site, to queue on the access road.
The modelling indicates that surrounding businesses and other road users will not experience
any significant impact.
The development of Lot 10 Railway Parade, Bayswater has been considered as part of this
Assessment. Traffic produced as a result of the development of Lot 10 Railway Parade is
expected to interact with traffic volumes surrounding the Site. However, all vehicles accessing
the Site during operations will access and depart the Site utilising Jackson Street and Collier
Road or Alice Street and Collier Road for Tonkin Highway and are not anticipated to utilise
Railway Parade or the new Wick Street/Jackson Street intersection.
Based on the modelling, available information and the assumptions made, the Facility will
have limited impact on the surrounding area and should not create a significant disturbance
to surrounding business or other road users in the area.
