Audit type Preliminary design road safety audit.

Purpose As part of the proposed Richmond Bridge and approaches upgrade a number of intersections in the surrounding road network will need to be upgraded. The purpose of this audit was to identify potential safety issues associated with a number of intersection upgrades proposed, as well as identify safety issues associated with any potential or perceived re-distribution of traffic.

Background In July 2012 the Richmond Bridge and Approaches Congestion Study was prepared by Hyder Consulting (Hyder) documenting traffic performance of the eight short-term improvement options (Options A to H) which have potential to improve traffic flow at Richmond Bridge and approach roads in the Richmond and North Richmond areas. Each option was assessed in terms of key traffic factors which are most likely to influence a decision on the best performing option. The Congestion Study has identified Option H as the best performing option.

This road safety audit is inclusive of the existing conditions as outlined in the scope (below), and the preliminary design of Option H.

Scope of audit The auditable materials included the following:

The Bells Line of Road/ Grose Vale Road/ Terrace Road intersection with

regards to:

Its current layout.

The concept option with reference number SK1108-1 and date 10 May

2012.

The concept option with reference number 30011177-120820-Gross-

Terrace-Int-Plan.

The Kurrajong Road/ Old Kurrajong Road intersection with regards to:

Its current layout.

The concept option with reference number SK1109-4 and date 16


Page 2 Hyder Consulting Pty Ltd-ABN 76 104 485 289


November 2011.

The Kurrajong Road/ Bosworth Street/ March Street intersection with regards

to:

Its current layout.

The concept option with reference number SK1108-4 and date 24 May

2012.

The concept option with reference number 30011177-120820-Bosworth-

Int-Plan.

The current layout of the local road precinct in Richmond and Agnes Banks

including:

Old Kurrajong Road – Yarramundi Lane from Kurrajong Road to

Crowleys Lane.

Crowleys Lane from Yarramundi Lane to Castlereagh Road.

Innalls Lane from Yarramundi Lane to Castlereagh Road.

Drift Road from Castlereagh Road to Innalls Lane.

This local road precinct is herein referred to as the Richmond-Agnes Banks local road precinct. The review of this precinct was in consideration of the other proposed intersection improvements described above.

These roads are depicted in Figure 1.

Audit team details Damien Chee, Hyder Consulting (level 3, lead auditor – RSA-02-0094).

Josh Kleinhans, Hyder Consulting.

Audit methodology

A day and night time inspection was carried out on 6 September July 2012. This included a walkover and drive through inspection of each of the intersections as well as the Richmond-Agnes Banks local road precinct. A follow up site inspection was also carried out on 13 September 2012.

Reporting of audit deficiencies in accordance with the NSW Centre for Road Safety’s Guidelines for Road Safety Audit Practices (2011).

Report includes a completed checklist as provided in the Austroads Guide to Road Safety Part 6. The audit team chose to use the existing road checklist rather than the one associated with preliminary design. This was due to the proposed intersection upgrades being retrospective improvements on an existing road network. Furthermore, it is understood that there are no current plans to upgrade the Richmond-Agnes Banks local road precinct. As such, this component of the audit was considered to be an existing road audit.

Report does not specify suggestions or recommendations for action. This is an RMS policy and the responsibility of the project manager, it will highlight the specific deficiencies of intersections, roads and the concept design as advised in the project scope.

Material supplied See Scope of audit.

Meeting and assessment details

Project start up meeting held on 4 September 2012

Site inspection carried out on 6 September 2012.

1.2 Responding to the audit report

Road safety audits provide the opportunity to highlight potential road safety problems and have

them formally considered by the project manager in conjunction with all other project

considerations.

The responsibility for the project rests with the project manager, not with the auditor. The project

manager is under no obligation to accept the audit findings. Also, it is not the role of the auditor

to agree to, or approve the project manager’s responses to the audit.




1.3 Previous audits and outstanding issues

A number of road safety issues were identified in the Richmond Bridge and Approaches

Congestion Study. These have not been formally raised as road safety deficiencies in this audit.

3 CONCLUDING STATEMENT

We have undertaken a preliminary design road safety audit using reference documents detailed

in Section 1 of this report.

The audit has been carried out for the sole purpose of identifying any features of road and

intersections surrounding Richmond Bridge that are deemed to be unsafe. These identified

issues to outline roadways which could be reviewed for safety performance.

Issues identified have been noted in this report for the Project Manager and Designer to review

and assess, and where appropriate make the necessary recommendations to improve safety,

this report does not make any suggestions and recommendations.
