…the scope of a project, route choice, selection of design standard, impact on the existing road network, route continuity, provision of interchanges or intersections, access control, number of lanes, route terminals, stage development, and more,
would be examined. In the draft design stage:
…horizontal and vertical alignment, sightlines, intersection layouts, land and shoulder width, pavement cross fall and superelevation, overtaking lanes, provision for parked and stationary vehicles, provision for cyclists and pedestrians, effects of departures from standards and guidelines, safety during construction, and so on,
are audited. In the detailed design stage before the preparation of contract documents, the auditor will assess:
…line markings, signing, delineation, lighting, intersection details, clearances to roadside objects, provision for road user groups with special requirements (for instance, pedestrians, cyclists, people with disabilities, trucks and buses), temporary traffic management and control during construction, drainage, poles and other roadside objects, landscaping, batters [slopes] and guard fencing.
At the pre-opening stage, auditors will drive and walk on the roads to assess the overall design and safety of the road. This method of auditing is conducted under all conditions, for example during the day and at night, in dry and wet weather. Lastly, auditing the in-service stage is appropriate for newly constructed and existing roads. The team systematically identifies weaknesses in the functioning of safety features while the road is open to motorists.
For every stage that is audited, an audit team makes a series of formal checks against established standards and guidelines. These guidelines serve a similar purpose as the accounting standards. These guidelines and checklists are outlined in AUSTROADS Road Safety Audits, 2nd Edition, 2002 (See Appendix I). The Roads and Traffic Authority of NSW also follows a similar set of guidelines when conducting road safety audits (See Appendix II). In practice, these checklists have proved to be very useful as reminders for auditors, but there is also a risk that they are too heavily relied on, and therefore auditors do not consider individual situations during the assessment. A combination of judgement, skill and systematic working is required to carry out an audit.
In order to conduct an audit, the auditor must have expertise in both highway design and road safety and be properly trained and experienced in carrying out audits in the same way that traditional auditors must have ‘tertiary education, are required to complete the education program of one of the two accounting bodies (CA Program or CPA Program) and also undertake continuing professional development throughout their audit career’.
In Britain, for example, the audit team includes ‘a road safety engineering specialist with expertise in crash investigation, a highway design engineer, and a person experienced in the safety audit procedure’. Specialists in the various areas join the team during certain audit stages. In Australia however, an auditor who is qualified under the Institute of Public Works Engineering Australia’s (IPWEA) Road Safety Auditor Accreditation scheme leads the team. The remainder of the audit team is comprised of people who are appropriately experienced within the area of construction being audited. In a similar manner, throughout the process of a traditional audit, the auditor too may require an expert’s opinion towards a particular subject matter, such an industry specialist, or technical specialist to provide a greater deal of specialised information.
The auditor must also possess communication skills, which are necessary to present audit results in a constructive manner in order to encourage a positive response from the design team. It is preferable to hire a small auditing team rather than a single auditor for two main reasons. As a team, each member can offer their skills and expertise thus generating better solutions and also as a team, individual biases are avoided thus making the auditing function more independent and successful. An integral part of the audit is monitoring and evaluating the process itself. Auditors should monitor the effectiveness of procedures and checklists and keep track of costs and benefits. Certain sections of the checklists may need to be altered in the future for example to take into consideration new technological developments or designs in the same way that certain auditing standards could be altered in relation to the changes within the profession.
The results of the audit should be documented and reported at each stage to the design team and in turn to the client of the scheme. The audit report usually includes recommendations for improvements to the design. Conducting safety audit reports, however, can sometimes lead to conflicts between the audit team, the design team and the client for the scheme. Therefore it is essential that prior to the audit a solid agreement be made (whether or not supported by law) that enables audits to be carried out successfully and the recommendations based on the audits to be implemented. This agreement can be likened to an “engagement letter” proposed by the external auditor to the client, which explicitly states the terms of the engagement and thus avoiding future misunderstandings between the parties.
Road Safety Audits have been adopted in NSW as an effective means of preventing potential crashes and reducing the severity of crashes should they occur. However, a road safety audit team cannot guarantee that crashes will not occur, even though the construction of the roadways are in accordance to safety standards. Road users, are human, and will make mistakes or law infractions on the road. In much the same way, a traditional auditor, provides assurance that the statements represent a ‘true and fair” view of the company’s financial status, however, it is not the auditor’s responsibility to detect fraud, and thus cannot guarantee that fraud does not exist.
Conclusion
The auditing function is a beneficial way of ensuring that a business’ practices, whether it be financial reporting or a construction of a road, is carried out in the most professional, ethical and safest way possible. The auditor has the responsibility of assessing the subject matter to provide end users of the financial statements (shareholders, creditors, investors and others) and roads (road users and pedestrians) a high level of assurance that the subject matter has been prepared in accordance to the required standards. More and more professions are seeing the opportunities audits provide and are making the auditing function an integral part of their business.
