Applications are sought that include appropriate infrastructure treatments to improve overall safety and reduce the risk of crashes. Because of the likely length of corridor treatments the type of infrastructure are typically focussed on the broader application of a range of lower-cost treatments rather than fewer, localised, high-cost treatments.
Types of infrastructure treatments envisaged under this program include:
- warning signs, including curve advisory speeds
- chevron alignment markers (CAMs) to highlight out-of-context curves or curves beyond crests
- guide posts
- centreline markings (on roads too narrow for continuous centreline, it may still be still be an option to install in the vicinity of curves and crests)
- Road widening. While it would likely be too expensive to treat and entire road, limited sections of widening could be proposed in the vicinity of high risk curves.
- tree and roadside hazard removal, particularly on the outside of curves
- short sections of safety barrier to protect against severe hazards
- sight distance improvements – vegetation removal or sight benching
- improved skid resistance – an over-representation of loss-of-control crashes in wet conditions may be an indicator of inadequate skid resistance
- reduced speed limits may be considered appropriate where, even after treatment, the road would remain significantly more hazardous than the surrounding road network.
