Traffic Management Plans are audited to ensure that traffic will be safely channelled through/past a work site, and to anticipate common driver behaviours that may result from confusion due to the changed conditions.
Engineering judgement is often called upon in situations where standards cannot necessarily be met. Expertise in barrier design and application and traffic engineering is also critical at this stage.
Following implementation of the Traffic Management Plan, an audit should be undertaken to assess how the plan is operating so that adjustments can be made as soon as possible where site conditions were not anticipated on the plan.

Why undertake a Construction/Traffic Management Audit?
- Changed road conditions in a confined space give rise to the potential for crashes
- Construction contractors are often not equipped with expertise in traffic management and will miss many subtle but important issues
- To check that signs and devices are standard to ensure consistency and clarity for road users
- To avoid conflicting messages between existing and temporary signs
- Check that all road users have been considered including road workers, motorists, cyclists and pedestrians
- Inner city construction sites often require a deviation from the standards in order to proceed due to the absence of space. Careful consideration and judgement is required to determine an acceptable deviation
- Minimise exposure to legal action in the event of an accident within the work zone
Typical Issues?
- Location, cleanliness and appropriateness of signage
- Suitability and installation of barriers, including termination
- Suitability/credibility of speed limits
- Proximity of workers to traffic
- Proximity of traffic to hazards caused by the works
- The appropriateness of the selected layout
- Conflicts between existing and temporary road furniture
- Taper lengths at merges
- The depth of boxed out sections
- Provision for all road users
- Implemented in accordance with latest standards
