1. Introduction

1.1 Traffic Engineering Report Layout

KCTT have been requested to provide a Traffic Engineering Report for the proposed development of Lot 18 (No 79) Victoria Road, Kenwick.

The purpose of this document is to provide commentary and analysis on the potential impact of large vehicles on Victoria Road, with particular attention paid to the integrity of the pavement and the condition of the intersection of Bickley Road and Victoria Road. The following is the scope of work in this report: -

Phase 1 – Conduct Background Research

• Collate all available traffic volumes from the City of Gosnells and Main Roads WA within 400 metres of the subject site. If no volumes are available, we will make an assessment of the likely traffic volumes in Victoria Road from our site inspection and the number of premises on Victoria Road, given Victoria Road is a cul-de-sac with access to the south to Bickley Road only. KCTT will also review the information we already have in our archives from the MKSEA project, where there are extensive vehicle volumes collated in the area of the subject site.

• Undertake a site visit and review any existing sight distance / road geometry issues which should be considered in the reporting. In particular, the City of Gosnells has expressed concern with the condition of the road, and the condition of the intersection of Bickley Road and Victoria Road.

• Collate all crash data for roadways and intersections within a 400 metre radius of the subject site. • Collate the road hierarchy information, roadway and carriageway widths for all roads directly fronting the

subject site.

Phase 2 – Traffic Engineering Report

• To estimate the likely volume of traffic attracted to the site on a daily basis, and to compare this with the likely current trip generation in Victoria Road.

• To provide an assessment of the condition of Victoria Road and the intersection of Victoria Road and Bickley Road, and if required, the timeframe the road is likely to handle that type of traffic movement before damage is done to the integrity of the pavement.

This report is not intended to be a Transport Impact Assessment, therefore the bulk of the standard information we provide as part of a TIA will not be provided as part of this assessment.

1.2 Notes Pertaining To This Report

This report has been provided to serve as a study for the proposed development of Lot 18 Vitoria Road, Kenwick. Particular attention will be paid to the condition of the pavement on Victoria Road and the intersection of Bickley Road and Victoria Road.

2. Traffic Engineering Assessment

2.1 Project Outline This Assessment considers the proposed development of Lot 18 Victoria Road, Kenwick (under the jurisdiction of the City of Gosnells). The proposed development will see the parking and storage of commercial vehicles, plant and material on site.

The purpose of this report is to address comments as follows from Officers at the City of Gosnells, as emailed to Mr David Maiorana on Wednesday 11th June 2014: -

“After review of the draft OCM report and the information presented within your 21 May 2014 email, my Manager advised that the City’s Traffic Engineer was to review the application.

The DA was subsequently internally referred to them. The response from the City’s Traffic Engineer is as follows [highlight added]:

“Victoria Road is classified as an Access Road under the City’s Functional Road Hierarchy with a desirable maximum traffic volume of 3,000 vehicles per day. Recent traffic count recorded a daily (24 hr) average weekday traffic volume of 646 vehicles. In terms of the traffic volume the road is performing below its capacity, however, the traffic count also recorded a high percentage (approx. 22%) of heavy vehicles traffic on the road. The road is a rural access road with designed pavement thickness and carriageway width to accommodate non-industrial type traffic. In the view of the fact that the development will generate heavy vehicles traffic, the applicant needs to demonstrate how the potential adverse impact on the road will be mitigated. A traffic impact assessment report that encompasses Stages 1 and 2 Road Safety Audit – Feasibility/concept/functional and how the adverse impact on traffic and road will be mitigated is required.

The Road Safety Audit is to assess the carriageway width, intersection (in particular the intersection of Victoria Rd and Bickley Rd) layouts, access location and the likely impact on the safety of all users of the road environment and the likely impact on the safety performance of active and passive travel on Victoria Road.”

2.1.1 Planning Context

Victoria Road is part of the Maddington Kenwick Strategic Employment Area (MKSEA) Stage 1. We were one of the consultants involved in significant studies in 2012 and 2013 into the future direction of industrial development in the region. We believe it is important that the proposed low-scale development of Lot 18 (No 79) in Victoria Road is recognised as part of the general movement in the area toward a potential formalisation of the MKSEA development area, and therefore greater intensification of land-uses in the future.

Therefore we believe that upgrade measures proposed in this report should consider the future potential intensification of land-uses and the ratification of the MKSEA Structure Plans due to the scarcity of strongly connected industrial landholdings in the inner eastern suburbs in the Perth Metropolitan Region.

Therefore any road upgrades / pavement assessments are looked at with a 3 to 5 year horizon.

2.1.2 Vehicular Access

The subject site fronts and offers direct vehicular access from Victoria Road, Kenwick.Victoria Road is classified as an Urban Local Road / Access Road by Main Roads WA (MRWA). Throughout its entirety, Victoria Road is a two-way two-lane undivided road with a speed limit of 50kph, which culminates in a cul-de-sac at its northern end.



PAGE 7

Access to Victoria Road is therefore by Bickley Road at the roads southern end. Moderate vegetation is present on both sides of the road reservation, this vegetation is close to the shoulder of Victoria Road in some locations. There are no bus services in Victoria Road. The current layout of Victoria Road would allow for full unrestricted movement of vehicles to and from the development.

The table below shows the most recent available traffic data for the surrounding network. The following information has been obtained from Main Roads WA.

Note * With reference to City of Gosnells traffic engineer, email dated 11th June 2014.

Note ** Vehicle volumes per day not available for Bickley Road. Estimates have been provided based on site visit investigations and have accounted for the functionality of the road and all access points.



PAGE 8

Note *** The likely vehicular volume per hour on Victoria Road and Bickley Road have been estimated based on the site visit investigation. In calculating these expected volumes, reduced activity overnight was considered due to the functional classification of the road.

In summary, while the existing percentage of heavy vehicles at 22% is high for a local access road, the volume of traffic at 646 VPD is low and is not approaching the theoretical capacity of a road of this nature which should be able to cater for 3,000 vehicle movements per day and up to 5% heavy vehicle composition within that 3,000 VPD. Therefore, the following comparative analysis means that the Victoria Road pavement should be suitably designed for the volumes of traffic: -

1. 646 VPD with 22% heavy vehicle traffic equates to approximately 142 semi-trailer movements per day 2. 3,000 VPD with approximately 5% heavy vehicle movements equates to approximately 150 semi-trailer

movements per day.

Therefore if Victoria Road has been constructed in accordance with the general requirements for an access road, the pavement should be currently suitable for the volumes of traffic (inclusive of the 22% heavy vehicle component) which is currently using the road.

2.1.3 Engineering Road Note No 9 Calculation

Main Roads WA Engineering Road Note No 9 provides the following calculation to determine pavement design requirements and characteristics: -

N = 365n d R c NVAG * 10-4

Where,

N = No of heavy vehicle axle groups

n = Annual average number of vehicles daily in one direction during year = 113,050 vehicles per year (using 646 VPD)

c = Percentage of heavy vehicles = 22.0%

r = Annual growth rate of heavy vehicles = 3.0% per annum

d = Percentage of heavy vehicles using that design lane = 100% (single lane in each direction only)

NHVAG = Average number of axle groups per heavy vehicle = 1 (semi trailers only, no tandems etc)

P = Pavement design life (years) = 5 years (consideration should be given to the MKSEA Structure Plan in the future

R = Cumulative growth factor = 5.31 based on Section 3.4 of Engineering Road Note No 9

Therefore N = 4820.4

From this equation a minimum required pavement thickness can be calculated: -

t = [219 – 211(log CBR + 58 log CBR2] log N / 120

Where: -



PAGE 9

CBR is assumed at 12%

N = 4820.4

Use of the above conservative inputs has generated a pavement thickness requirement of 95mm. We believe that a pavement thickness of around 330 to 350mm would have been used for this type of Access Road with a profile as follows: -

• 25 or 30mm AC10 asphalt • 150 to 200mm base course • 100 to 150mm sub-base course

We therefore believe that a 3 to 5 year pavement design life is conservative as per our previous comments, and that the structural integrity of the pavement, if built to a minimum 200mm thickness on a sub-grade compacted to CBR = 12% is more than suitable for the existing traffic volumes, additional vehicle volumes on this site as nominated in this report, plus a general allowance for 3% per annum growth from other landholdings on this road.

In summary, due to no accidents in Victoria Road during the previous 5 years, we believe that the existing road is functioning reasonably with 22% heavy vehicles.

2.1.5 Vehicle Parking Requirements

The subject site will primarily be used for the storage of commercial vehicles as well as other plant and materials. With the provision of a hardstand area for the storage of vehicles, there is sufficient area provided to meet parking requirements. The site offers 2 formal parking bays for staff and visitors and offers suitable area for semi-trailer access / egress and turning requirements within the property.

Consideration should also be given to the fact the site maintains a residential premise.

2.1.6 Vehicle Trip Attraction

The proposed development will allow for the parking and storage of commercial vehicles, plant and materials within allocated areas on the subject site (refer Appendix 1 for details of the proposed layout).

We believe the trip attraction to this site is likely to be demand / supply based and therefore there may add minimal movements over the top of existing residential trip generation on general days, with some increased trip



PAGE 11

attraction on other days. Given the size of the site, we believe it will attract a maximum of up to 50 vehicle movements per day, (including existing residential uses around 6.7 VPD), with a theoretical maximum of around 20 semi-trailer movements per day. It should be assumed that 50% of these semi-trailer movements will be fully-laden, with the other 50% empty (without additional loading).

For the purposes of pavement integrity review, we believe the development is likely to add a maximum of an extra 15 vehicle movements per day with 30% heavy vehicle component.

2.2 Traffic Flow

Victoria Road ends at a cul-de-sac at the north, with access via Bickley Road from the south. Vehicles will therefore travel via Bickley Road and Victoria Road to reach the subject site. Turning movements for a 19 metre semi-trailer truck are attached in Appendix 2. We have modelled the following movements only: -

• Left-out from Victoria Road into Bickley Road • Right-in from Bickley Road into Victoria Road

We recognise that it should be a requirement of any acceptance of this development proposal that heavy vehicles are not permitted to enter / exit the site from Bickley Road to the northwest of Victoria Road.

2.2.1 Review of Pavement Integrity and Sight Distances

This section incorporates photographs from our site inspections in August 2014.

Victoria Road has a designated legal speed limit of 50 km/hr. Austroads Guide to Road Design Part 3: Geometric Design Table 5.5 shows a desirable sight distance of 91 metres for semi-trailers with a reaction time of 2.5 seconds. This was taken into account during the site visit conducted on Monday the 25th of August 2014, with the results shown below: -



PAGE 12

Figure 2 - Sight Distance from access road looking north

Figure 3 - Sight Distance from access road looking south

The rounded edges of the pavement are generally in strong condition as noted above and are showing limited signs of deterioration with 22% heavy vehicle traffic. The following photographs highlight the extent of minor cracking along Victoria Road, which we do not believe shows the beginning of any concerning structural defects in the integrity of the pavement.

Clear line of sight from access road to Lot 18 (No 79) looking north. Vehicle travelling southbound is approximately 90 metres away.

The photo shows the line of sight from access road looking south. Colleague standing at crest of hill is approximately 40 metres away. Given the likelihood of right turns from this premise is low, adherence to this sight distance criterion is not critical.

Limit of pavement damage on Victoria Road – from Bickley Road to subject site. Minimal “crocodile cracking” observed, with 1mm wide cracks. These are minor.

Limit of pavement damage on Victoria Road – from Bickley Road to subject site. Approximately 2mm wide crack observed



PAGE 14

The above photographs confirm minimal damage is present along Victoria Road. An increase of an average of 15 vehicles per day (averaged on an annual basis) due to this development will not unduly stress the pavement along this road.

Therefore, we do not believe there are any remedial works required in Victoria Road along the alignment.

The general width of Victoria Road varies between 7.5 metres near Lot 18 (No 79) Victoria to 6 metres in some sections of the pavement.

2.2.2 Intersection of Victoria Road / Bickley Road

The intersection of Victoria Road and Bickley Road is showing signs of wear on the edges of the pavement formation with vehicle tyre movements through soft sandy shoulders evident during our inspection. We believe the following issues are present at this intersection: -

• The angle between Victoria Road and Bickley Road means left turn movements from Victoria Road into Bickley Road are slightly more difficult than at a 90-degree t-intersection.

• There is no curve widening to allow for the movement of semi-trailers out of Victoria Road.

Figure 6 – Vehicle movements through shoulder at Victoria Road / Bickley Road intersection

We recommend reconstruction and widening of pavement around the radius to suit semi-trailer vehicle movements. This should be done on a contribution basis by various landowners in Victoria Road who are currently proposing to expand their home-business based activities. Reconstruction should include the

2.3 Daily Vehicular Volumes and Vehicular Types

It is anticipated that the storage use at the subject site will generate an average maximum of 15 additional vehicle movements per day. As discussed earlier in this report, we believe this is a conservative assessment as the use of the storage area is not intended as a daily pick up and receival. The intent is for longer term storage requirements.

Victoria Road is sealed and deemed suitable to accommodate the vehicle movements generated by the proposed use, it is also considered to be constructed to a suitable standard for such infrequent traffic movements. The maximum proposed vehicle size is a semi-trailer (or 19.0m length vehicles).

It is also worth noting that we have been informed by the client that once plant and equipment have been established on site, the frequency of vehicle movements is likely to decrease to less than 1 truck movement per week, however for the purposes of creating a robust assessment we have reviewed the integrity of the pavement based on 15 vehicle movements per day average.

2.4 Conclusions

The following are the key conclusions from our site assessment: -

1. The proposed property access / egress has been suitably designed to accommodate semi-trailer movements into and out of the property.

2. The sight distances are in accordance with Austroads requirements for right turn movements into the facility and left turn movements out.

3. A crest in Victoria Road is located approximately 40 metres to the southwest as evidenced in our photograph. The sight distance to this location is clear, and is likely to allow clear sight distances to approximately 60 to 70 metres. This sight distance however is not applicable as vehicles will not be turning right from the subject site into Victoria Road, therefore the potential point of conflict should not exist.

4. Should the City of Gosnells have concerns with this the following management measures can be put in place: 4.1. Crest or similar signage can be used in this location to signify to northeast bound traffic that sight

distances may be impaired to local driveways. 4.2. The City of Gosnells can stipulate that no right turn movements will be allowed outside of the subject

site and that all vehicles must access / egress the site via Bickley Road and Victoria Road. 5. The existing pavement is in a robust condition and does not require patching or re-working in any location

between Lot 18 (No 79) Victoria Road and the intersection of Victoria Road / Bickley Road. 6. The existing intersection of Bickley Road and Victoria Road is deficient in design for left-out semi-trailer

vehicle movements from Victoria Road into Bickley Road southeast-bound. 7. We propose that a contribution system is commenced to allow for a reconstruction of the left-turn from

Victoria Road to Bickley Road. These works would include: - 7.1. Widening of the pavement with a minimum 300mm sub-base and base-course, plus 30mm AC10 or

40mm AC14 intersection mix in accordance with direction from the City of Gosnells. 7.2. Provision of a mountable keyed kerb to protect the pavement edges on the reconstructed intersection

radii (left-out from Victoria Road only). 7.3. All backfill behind the kerbing to be placed and compacted to top of kerb to City of Gosnells

requirements to provide appropriate strength in sideways movements. 7.4. New paint marking delineating the centreline of Victoria Road at the widened intersection. We do not

believe that the provision of a splitter island at this intersection will improve vehicular access / egress as it is likely to become a maintenance issue for the City of Gosnells.



PAGE 18

7.5. We do not believe any other upgrades are required to this intersection. 8. Pavement calculations using Engineering Road Note No 9 and using a CBR of 12 for the compaction of sub-

grade materials shows that the road pavement should be considered satisfactory for a road with approximately 650 vehicles per day, with around 22% heavy vehicle volumes.

9. While the existing percentage of heavy vehicles at 22% is high for a local access road, the volume of traffic at 646 VPD is low and is not approaching the theoretical capacity of a road of this nature which should be able to cater for 3,000 vehicle movements per day and up to 5% heavy vehicle composition within that 3,000 VPD. 646 VPD with 22% heavy vehicle traffic equates to approximately 142 semi-trailer movements per day.

10. 3,000 VPD with approximately 5% heavy vehicle movements equates to approximately 150 semi-trailer movements per day. Therefore if Victoria Road has been constructed in accordance with the general requirements for an access road, the pavement should be currently suitable for the volumes of traffic (inclusive of the 22% heavy vehicle component) which is currently using the road.

11. Existing pavement widths in Victoria Road appear to be suitable given the low traffic volumes. Consideration should be given to widening Victoria Road in the future as part of the MKSEA Structure Plan, such that the road is suitable for movement of vehicles up to 3,000 VPD with a high percentage of heavy vehicle movements.

12. The use of all existing properties on Victoria Road in a similar manner to that proposed on this site is not expected to increase existing traffic volumes beyond 1,000 VPD therefore we do not believe there is merit in widening sections of Victoria Road until the MKSEA Structure Plan is ratified and a formal contributions scheme or a land developer acquires a significant amount of land / puts forward a significant and intensive land-use proposal.

13. Given the site is a storage facility it is reasonable to assume that vehicles will enter or exit the site full-laden, however leave in the opposite direction empty. The lighter vehicle mass of an empty semi-trailer is not considered separately in the pavement design calculations.

14. The future MKSEA Structure Plan Stage 1 should be considered in the short-term requirements for landowners seeking to build home-based businesses which add marginal traffic volumes to the existing road network.

This assessment has been completed by a qualified civil engineer to Masters level and Road Safety Assessment qualifications. Colin Kleyweg is listed on Main Roads WA website as having met the requirements for this course and has completed numerous road safety assessments in the last 5 years including recently for the Shire of Exmouth, Shire of Kalamunda and for private clients in the City of Wanneroo.

Colin Kleyweg is also currently providing expert opinion in civil engineering and road engineering design matters to the State Solicitors Office for Western Australia Government clients including the Commissioner of Main Roads WA and the Western Australian Planning Commission. Therefore we believe the qualifications of the author should provide the City of Gosnells with some comfort that the information contained in this report is robust and equitable to all parties.
