Road Assessment Program
The Australian Road Assessment Program (AusRAP) will help the WA State Government ensure that eventually all sections of national highway in Western Australia which score poorly are prioritised for improvements and upgrades. The risk ratings will also provide road planners and engineers with vital benchmarking information to show them how well, or badly, a particular road performs compared with others.
- AusRAP analyses the crash history and the amount of traffic on each section of the national highway network. The relevant roads are then ranked according to the level of safety they offer and their risk to road users.
- AusRAP will help ensure that the sections of national highway in WA which score poorly are prioritised for improvements and upgrades.
- AusRAP has developed two standard protocols for risk mapping of casualty crashes and a star rating system for roads, using a Road Protection Score (RPS). Using these protocols, roads are rated for safety.
- The AusLink National Network is more than 20,000km in length.
- It generally represents the National Highway System and some of the roads previously classified as Roads of National Importance, additional strategic links, and a number of metropolitan roads that link to major freight terminals.
- AusRAP gives roads across Australia a safety rating, which in turn ensures that the risk of death and injury on different roads more meaningful, stimulates public discussion - and action.
- AusRAP will help road users understand how risk can vary according to changes in the road environment. Risk-aware road users will be more likely to adapt their driving to reduce their risk of a crash.
- The risk ratings will also provide road planners and engineers with vital benchmarking information to show them how well, or badly, a particular road performs compared with others.
- The National Road Safety Strategy 2001-2010 (the National Strategy) shows that nearly half of the targeted improvement in road trauma can be achieved by upgrading Australia's roads.
We can avoid crashes by redesigning roads to make them safer. There are many design elements which contribute to the safety of a road. These include:
- Installation of barriers to separate oncoming traffic.
- Widening and sealing shoulders (or road edges).
- Installing audible edge lines.
- Removing roadside hazards such as trees and poles.
- Providing overtaking lanes.
- Providing line markings.
- Installing advisory speed signs.
- Resurfacing roads.
Black spots
Some road traffic sites have a history of many road traffic crashes. Other sites or sections of roads may be identified from Road Safety Audits to have a high likelihood of crashes because of their design, construction or maintenance. Various measures or road treatments can be undertaken to reduce the chance of road crashes at Black Spot sites. Treatments include:
- Roundabouts.
- Traffic control signals.
- Traffic island on approaches to intersections.
- Seagull islands at intersections.
- Indented right turn pockets (lanes) with islands.
- Left turn slip lane.
- Medians added to existing roads.
- Nibs (pedestrian 'refuge' facilities).
- Ban right turns.
- Non-skid treatments.
- Improve/reinforce priority signs.
