Whatley Crescent is a dual undivided carriageway in the vicinity of the site. Roberts Street is a single undivided
carriageway in the vicinity of the site. The unsignalised intersection of Whatley Crescent/Roberts Street is located
midblock between the signalised intersections of Garratt Road/Whatley Crescent and King William Street/Whatley
Crescent and operates under Give Way control on the Roberts Street approach. The existing geometry of the
intersection is shown in Figure 4.
Figure 4: Existing Whatley Crescent/Roberts Street Intersection Geometry
Existing traffic volumes were obtained via SCATS data from Main Roads Western Australia for Whatley Crescent
in the vicinity of the site and have been supplemented by turning movement surveys undertaken at the Whatley
Crescent/Roberts Street intersection on Wednesday 17th September 2014. The existing daily volumes on Whatley
Crescent, east of Garratt Road are in the order of 18,700 vpd (March 2014). Daily volumes were not available for
Roberts Street but based upon the results of the peak period traffic counts, it is estimated that the daily volumes
are in the order of 1,400 vpd. The existing traffic volumes are shown in Figure 5.

These volumes were then used as input into the intersection modelling program SIDRA to assess the existing
traffic operations at this location. The results of this traffic assessment are detailed in Section 4.
2.2 PUBLIC TRANSPORT, PEDESTRIAN, AND CYCLIST FACILITIES
The site is located approximately 450m walking distance to Bayswater Railway Station which is located to the
north-east of the site. The closest bus stops are located on Whatley Crescent, east King William Street, and on
both sides of King William Street, south of Whatley Crescent. Local bus services include Route 48 (Morley Bus
Station – Perth via Bayswater Station, Guildford Road and Lord Street) which operates a 20 to 30-minute service
during weekday peak periods and hourly service during the midday and on weekends. The Circle Bus (Routes
98/99) also operate on King William Street and provides high frequency service to major centres and activity
nodes within the middle suburban areas of Metropolitan Perth such as tertiary educational institutions, hospitals,
employment nodes, regional centres and shopping centres. Figure 6 shows the existing public transport services
in the area.
A dual use path is in place on the south side of Whatley Crescent and a Principal Shared Path is in place on the
north side adjacent to the railway line. A footpath is in place on the east side of Roberts Street. Figure 7 shows
the cycling and pedestrian infrastructure in the vicinity of the site. Leake Street to the east of the site has also
been classified as a bicycle-friendly street.

3. PROPOSED DEVELOPMENT
A site plan of the proposed development has been prepared by Tuscom Subdivision Consultants. A copy of the
site plan is contained in Appendix A.
3.1 PROPOSED LAND USES
The proposal seeks the development of 16 multiple-dwelling residential units. The proposed residential
development is to be constructed on the site which is currently occupied by a single family dwelling, which is
located on the south side of Whatley Crescent, west of Roberts Street. In the suburb of Bayswater
3.2 PROPOSED ACCESS AND PARKING ARRANGEMENTS
The proposed access arrangements are shown to consist of a single crossover to be located to the south side of
Whatley Crescent, approximately 45m west of Roberts Street and to the north side of the ROW for
service/delivery/rubbish collection purposes approximately 75m south of Whatley Crescent. No access to the site
is proposed via Roberts Street directly.
Direct access to the ground floor area car parking area will be accommodated via crossovers from both the ROW
at the southern end and via Whatley Crescent at the northern end of the development. Proposed car parking
supply consists of 16 bays plus 3 visitor bays (total of 19 bays) which is consistent and compliant with State
Planning Policy 3.1: Residential Design Codes as the site is located within 800m of a high frequency railway line.
Rubbish collection will be undertaken via kerbside collection via Whatley Crescent and the rear ROW to Roberts
Street and a separate Waste Management Plan will be prepared in consultation with the City of Bayswater during
the detailed design stages of the project.
3.3 END OF TRIP FACILITIES
End-of-trip facilities (including bicycle racks) are proposed to be provided on the site within individual storage
lockers and consistent with Austroads guidelines.
4. TRANSPORT ANALYSIS
A traffic generation and distribution exercise has been undertaken to assess the potential traffic impacts
associated with the proposed development. The aim of this exercise was to establish the traffic volumes which
would be generated from the proposed development and to quantify the effect that the additional traffic has on the
surrounding road network, specifically on the intersection of Whatley Crescent/Roberts Street and on the
crossover intersection to Whatley Crescent.
4.1 TRIP GENERATION
The traffic generated by the proposed development has been predicted by applying trip generation rates for the
Residential Condominium/Townhouse (230) category. These rates were derived from the Institute of
Transportation Engineers’ (ITE) Trip Generation Manual, 8th Edition. This trip generation represents the ‘worst
case’ scenario as the anticipated net site traffic increase has not been adjusted to reflect a the existing traffic
generated by the uses currently operating on the site, which typically result in a reduction in net impact on the
boundary road system. The total anticipated traffic generated by the proposed development is estimated to be in
Client Name: Tuscom Subdivision Consultants October 2014
Project Name: 139 Whatley Crescent
MC_139 Whatley Crescent_TIA_V3_081014.docx 8 Move Consultants
the order of 93 vehicular trips (50% inbound/50% outbound) on a daily basis; 7 vehicular trips (1 inbound/6
outbound) during the a.m. peak hour; and 8 vehicular trips (5 inbound/3 outbound) during the p.m. peak hour.
4.2 TRIP DISTRIBUTION
Based upon the existing traffic patterns in the area and the spatial distribution of adjacent land uses, the following
distribution for the proposed ‘new’ development generated traffic has been assumed:
60% to and from the west via Whatley Crescent;
40% to and from the east via Whatley Crescent; and
2 to 3 vpd maximum at rear entering/exiting ROW (service/delivery vehicles only).
The number of trips entering / exiting the site via the proposed site crossover to Whatley Crescent has been
assigned based upon the most logical route for vehicles to take given their origin / destination. Figure 8 and
Figure 9 shows the site-generated traffic at the site crossover and at the Whatley Crescent/Roberts Street
intersection.
The anticipated site-generated traffic was then been assigned to the respective crossovers to Whatley Crescent
and Roberts Street based upon the proportions for both the weekday a.m. and p.m. peak hours. The resultant
increases in weekday daily and a.m. and p.m. peak hour-generated traffic under the ‘worst case’ scenario for the
boundary road network would be as follows:
Whatley Crescent:
o Daily: +93 vpd
o A.M. Peak Hour: +7 vpd
o P.M. Peak Hour: +8 vpd
Roberts Street:
o Daily: +4 to 6 vpd
o A.M. Peak Hour: +2 to 3 vpd
o P.M. Peak Hour: +2 to 3 vpd
These increases in daily and a.m. /p.m. peak hour volumes will have a negligible impact on existing traffic
operations in the area and represent an increase in daily volumes of less than 1% on Whatley Crescent and
Roberts Street.

4.3 INTERSECTION AND CROSSOVER ASSESSMENT
4.3.1 SIDRA Intersection Analysis
The operational performance of the signalised intersection of Whatley Crescent/Roberts Street intersection and
Whatley Crescent crossover locations was assessed using the software program SIDRA Intersection 6.0. This
was undertaken for existing conditions and also with the addition of the development generated traffic. In addition,
the operation of the site crossover was analysed for when the development is in place.
SIDRA is a commonly used intersection modelling tool used by traffic engineers for all types of intersections.
Outputs for four standard measures of operation performance can be obtained, being Degree of Saturation
(DoS), Average Delay, Queue Length, and Level of Service (LoS).
Degree of Saturation is a measure of how much physical capacity is being used with reference to the
full capability of the particular movement, approach, or overall intersection. A DoS of 1.0 equates to full
theoretical capacity although in some instances this level is exceeded in practice. SIDRA uses maximum
acceptable DoS of 0.90 for signalised intersections for its Design Life analysis. Design engineers
typically set a maximum DoS threshold of 0.95 for new intersection layouts or modifications.
Average Delay reports the average delay per vehicle in seconds experienced by all vehicles in a
particular lane, approach, or for the intersection as a whole. For severely congested intersections the
average delay begins to climb exponentially.
Queue Length measures the length of approach queues. In this document we have reported queue
length in terms of the length of queue at the 95th percentile (the maximum queue length that will not be
exceeded for 95 percent of the time). Queue lengths provide a useful indication of the impact of signals
on network performance. It also enables the traffic engineer to consider the likely impact of queues
blocking back and impacting on upstream intersections and accesses.
Level of Service is a combined appreciation of queuing incidence and delay time incurred, producing an
alphanumeric ranking of A through F. A LoS of A indicates an excellent level of service whereby drivers
delay is at a minimum and they clear the intersection at each change of signals or soon after arrival with
little if any queuing. Values of B through D are acceptable in normal traffic conditions. Whilst values of E
and F are typically considered undesirable, within central business district areas with significant
vehicular and pedestrian numbers, corresponding delays/queues are unavoidable and hence, are
generally accepted by road users.

4.3.2 Results of SIDRA Analysis
The results of the SIDRA analysis under existing and proposed peak hour conditions are detailed Appendix B.
The results indicate that the intersection of Whatley Crescent/Roberts Street will continue to operate at excellent
Levels of Service during the weekday a.m. and p.m. roadway peak hours and that the proposed crossover to
Whatley Crescent will also operate at excellent Levels of Service during these periods. The minimal increases in
vehicular traffic on Roberts Street south of Whatley Crescent are generally concentrated on a short section of this
road between the ROW and Whatley Crescent and it is anticipated that the site-generated traffic will have a
negligible impact on the adjacent local road system.
In conclusion, it should be noted that based both on a review of the modelled total traffic assessment and
observed traffic operations of the boundary road system, the anticipated site-generated traffic associated with the
redevelopment proposal is negligible and that no external boundary road improvements will be required.
5. VEHICULAR ACCESS AND PARKING
5.1 ON-SITE QUEUING, CIRCULATION AND ACCESS
The site plan indicates a single proposed crossover to be located on Whatley Crescent, approximately 45m west
of the intersection with Roberts Street, and an access for service/delivery/rubbish vehicles via the ROW along the
southern boundary of the site. No direct access is proposed to Roberts Street. This primary crossover to Whatley
Crescent has been designed to consist of a minimum of 6 metres to accommodate both inbound and outbound
movements with all movements to be accommodated in forward gear.
A review of the proposed on-site circulation and car parking layout was undertaken to assess the adequacy of the
proposed site access and circulation in addition to service/delivery areas on the site. The design of the proposed
car parking areas adjacent to the rear of the building on the site has been reviewed using AutoTrack and the
relevant Australian Standards and Austroads guidelines, with the proposed design considered adequate to
accommodate on-site manoeuvring and circulation. Rubbish collection will be undertaken via kerbside pickup and
service/delivery will be accommodated via entry from Whatley Crescent and exit via the ROW access at the
southern boundary of the site to Roberts Street. Details relating to the Waste Management aspects of the project
will be negotiated directly with the City of Bayswater during the detailed design stages of the project.
5.2 SIGHTLINE REVIEW AND CRASH HISTORY
A review of the sightlines along Whatley Crescent for exiting and entering vehicles in the vicinity of the proposed
crossover location has been undertaken and it can be concluded that the sightlines meet minimum Austroads
sightline requirements.
A review of the crash history for the reporting period of 2009-2013 indicates only 3 crashes relating maneovering
into or out of a driveway between Garratt Road and King William Street with only 1 crash on Roberts Street south
of Whatley Crescent. This very low number of crashes, particularly in the context of the traffic volumes on
Whatley Crescent, indicates that the additional traffic associated with the development will have a negligible
impact on the risk profile at this location.

5.3 PARKING DEMAND AND SUPPLY
The required car parking supply for the site, based upon the City of Bayswater’s Town Planning Scheme No. 24
and State Planning Policy 3.1: Residential Design Codes is 18 bays. The proposed supply on the site is 19 bays,
including 3 visitor bays, which is consistent with the R-Codes, including visitor bays. It should be noted that the
location of the site due to its location within close walking distance of high quality and high frequency bus and
railway services enhances its accessibility to alternative transport modes. On-street car parking is also available
on Roberts Street east of the site for visitors, if required.
In addition, the WAPC’s Development Control Policy (DC) 1.6: Planning to Support Transit Use and Transit
Oriented Development provides the following guidance with respect to car parking concessions due to proximity
to public transport options.
Excerpts from Clause 4.6: state “…in carrying out the necessary analysis as part of the local planning strategy
process, and in developing related planning provisions, local governments should have particular regard to
matters such as…”:
the encouragement of public transport use over car use;
the encouragement of mixed use development, both generally and within individual developments;
the development and application of scheme parking standards that reflect the availability within the
precinct of transit facilities and that provide discretion to vary standards, and to progressively replace
surface level car parking close to stations with other more transit supportive uses over time;
the potential to use planning provisions to provide incentives for appropriate development in transit
oriented precincts, including reduced parking standards and floor-space ‘bonuses’; and
For the immediate environs of transit facilities, local government is encouraged to consider the
preparation of precinct plans that provide greater detail with respect to both land use and the physical
form and relationship of development in the precinct to the transit facility, including design guidelines.”
It can therefore be concluded that a proposed reduction in statutory parking allocation maintains this aim through
a corresponding restriction in on-site parking supply. This is known to be a primary factor in promotion of mode
shift away from car-as-driver modes and towards single car households utilising the available alternative modes
including carpooling, public bus transport and cycling. The location of the subject site proximal to a major public
transport and other non-motorised transport infrastructure for these alternative modes will assist in the transition
towards more sustainable transport in the area.
This approach is also consistent with the stated objectives of Western Australian Planning Commission in
documentation including and Directions 2031 and Beyond and Liveable Neighbourhoods.
6. CONCLUSIONS
The aim of this Transport Impact and Car Parking Assessment was to discuss the traffic likely to be generated by
the proposed residential 16-unit multiple dwelling development proposed at 139 Whatley Crescent, Bayswater, in
the City of Bayswater to assess the impacts associated with anticipated site-generated upon the adjacent
transport infrastructure. In particular, the assessment considered the impacts on the nearby unsignalised
intersection of Whatley Crescent/Roberts Street as well as on the frontage of the site.

A detailed SIDRA analysis was undertaken for the unsignalised intersection of Whatley Crescent/Roberts Street
and at the site crossover to Whatley Crescent indicates that these locations will operate at excellent Levels of
Service during the future weekday a.m. and p.m. peak periods and the addition of site-generated traffic will have
a negligible impact on the boundary road network.
The proposed access arrangements are shown to consist of a single crossover 6m wide to the south side of
Whatley Crescent approximately 45m west of Roberts Street. The results of the SIDRA analysis under existing
and proposed peak hour conditions are detailed Appendix B. The minimal increases in vehicular traffic on
Roberts Street are concentrated on a short section south of Whatley Crescent with additional increases in traffic
easily accommodated within its existing practical capacity and functional road classifications of both Whatley
Crescent and Roberts Street of the roads adding less than 1% to the existing base traffic volumes on a daily
basis.
Site observations indicate that good visibility is available in both directions along Whatley Crescent and a review
of the crash history for the reporting period of 2009-2013 indicates only 3 crashes relating maneovering into or
out of a driveway between Garratt Road and King William Street with only 1 crash on Roberts Street south of
Whatley Crescent. This very low number of crashes, particularly in the context of the traffic volumes on Whatley
Crescent, indicates that the additional traffic associated with the development will have a negligible impact on the
risk profile at this location.
A review of the proposed on-site circulation and car parking layout was undertaken to assess the adequacy of the
proposed site access and circulation in addition to service/delivery areas on the site. The design of the proposed
car parking areas adjacent to the rear of the building on the site has been reviewed using AutoTrack and the
relevant Australian Standards and Austroads guidelines, with the proposed design considered adequate to
accommodate on-site manoeuvring and circulation. Service/delivery and rubbish collection will be undertaken
through kerbside pickup via entry from Whatley Crescent and exit via the ROW at the rear of the site to Roberts
Street and will be negotiated in consultation with the City of Bayswater. The proposed crossover to Whatley
Crescent has been designed to a width of 6 metres will be sufficient to accommodate entry and exit by site-
generated traffic.
The proposed on-site car parking supply for the site is consistent with the City of Bayswater’s Town Planning
Scheme No. 24, the Residential Design Codes and State planning policies. The proposed on-site supply is 19
residential bays including 3 visitor bays.
In conclusion, it should be noted that based both on a review of the modelled total traffic assessment and
observed traffic operations of the boundary road system, the anticipated site-generated traffic associated with the
proposed development can be accommodated within the existing practical capacity and functional road
classification of the local road system.
