Treatments and measures

Terminology

• Treatments are applied directly to the roading infrastructure.
• Measures act on driver behaviour.

Overtaking treatments

Depending on the road section strategy, overtaking treatments include:

• overtaking sight distance improvements:
• batter relocation
• vegetation control
• pavement rehabilitation (involving changes to vertical and/or horizontal alignment)
• road realignment
• overtaking enhancements (where overtaking currently occurs or is likely to occur):

• seal widening

• overtaking in opposite direction at passing lanes and slow vehicle bays

• configuration of passing lanes and slow vehicle bays (to preserve existing overtaking zones).

For more detail on where overtaking opportunities are applied, see the Tool kit of options and Long-term framework for passing and overtaking treatments, which are both under Technical information, Passing and overtaking documents.

See also appendix A Tool kit of options and appendix C Long-term framework for passing and overtaking treatments under Technical information, Conference publications, Regional passing and overtaking plans: A bridge between high-level policy and localised solutions.

Passing treatments

Depending on the road section strategy, passing treatments include:

• 2+1 lanes (ie continuous alternating passing lanes)

• passing lanes

• crawler lanes (for specific situations, also known as climbing lanes)

• slow vehicle bays

• diagonally marked wide sealed shoulders (on flat/rolling gradients)

• diagonally marked crawler shoulders (on hilly mountainous gradients).

Supporting treatments and measures

As well as overtaking and passing treatments, a range of supporting treatments and measures will also be applied, depending on the road section strategy:

• centreline treatments,

• roadside/edgeline treatments,

• intersections treatments,

• resource planning measures,

• education measures,

• enforcement measures,

• travel demand management (TDM) measures,

• intelligent transport systems (ITS) measures.
